How to create a simple calculator in visual basic 60

In the following tutorial, we will understand how to create a Body Mass Index (BMI) Calculator with the help of the Python programming language. But we get started creating one; let us briefly discuss what Body Mass Index (BMI) is.

Understanding the Body Mass Index (BMI)

BMI, short for Body Mass Index, is a measure of relative weight based on the mass and height of an individual. We generally use the Body Mass Index in order to categorize people on the basis of their height and weight. These categories are underweight, healthy, overweight, and even obesity. Moreover, it is also adopted by various countries in order to promote healthy eating.

We can consider Body Mass Index (BMI) as a substitute for direct measurements of body fat. Besides, BMI is a low-cost and easy-to-perform method of screening for weight classes that may cause health-related problems.

Understanding the working of BMI Calculator

A BMI Calculator accepts the weight and height of an individual and calculates the Body Mass Index (BMI) of that person.

For Example, if the height and weight of a person are 155 cm and 57 kg. The BMI of that person will be 23.73 (approx.), which signifies that the person is healthy.

Body Mass Index (BMI) is a measure of body fat on the basis of height and weight, respectively.

On the basis of the BMI of an individual, the calculator returns a statement stating the overall health of the person.

The following table shows how the classification of BMI is done in order to identify the health status of a person.

S. No. BMI Weight Status
1 Below 18.5 Underweight
2 18.5 – 24.9 Normal
3 25.0 – 29.9 Overweight
4 30.0 and above Obese

Now, let us begin coding the project.

Creating BMI Calculator using Python

As the first step, we will create a New Python program file and name it Within this file, we will begin by creating a block of code to ask the user their height and weight. We can easily accomplish this using the input() function.



In the above snippet of code, we have defined two variables as the_height and the_weight which uses the input() function to accept input from the user. We have also included the float() function outside the input() function in order to convert the input string into the float data type so that we can perform calculations with it.

Next, we will calculate the Body Mass Index.

We will use the following formula in order to calculate BMI.

Let us implement the above formula in the Python program.



In the above snippet of code, we have defined a function for BMI using the above formula. We have divided the height by 100 to convert the centimeters into meters.

Now, let us print the BMI.



In the above snippet of code, we have printed a statement stating BMI of the person.

Now, we will print the statement stating the present health of the user based on their BMI. This block of code will be quite simplified for better understanding.

We will use the if-elif-else conditions for classification.



In the above snippet of code, we have used the value of the variable the_BMI in the if-elif-else statement to check if the BMI of the person lies within one of the categories.

The program will print the statement on the following basis:

  1. If BMI is less than or equal to 18.5 then the program returns the condition for underweight.
  2. If BMI is less than or equal to 24.9 then the program returns the condition for Healthy.
  3. If BMI is less than or equal to 29.9 then the program returns the condition for overweight.
  4. If none of the above conditions are True then the program returns the condition for obese.

Hence, the program is completed.

Let us see the complete source code for the program and output for the same.


How to create a simple calculator in visual basic 60

This is a Sample calculator that I created in visual basic 2008, and this sample will be more useful for learners who are interested in VB 2008 and fortunately the VS 2019 can upgrade the source code perfectly. You can study it and modify it as more as you like.

How to Build a Simple Calculator

First, create an Interface for your calculator which has the following:

  • TextField
  • Buttons for the numbers
  • Buttons for the Operators
  • Button for the Result
  • Off, Clear, and Backspace Button

In my Case, this is the interface I used. How to create a simple calculator in visual basic 60

After that, set the variables for the operator, value 1, value 2, and other needed for operations.

Then, for each number buttons. For script below, my textfield named as “txtInput” and “cmd1” for my number 1 button.

For the operation buttons except for the square root button, follow the script below and change the “[Operator]” value according to the operator you have set to the button.

And for the equal/result button. Use the following code below.

Next is we will create the function that calculates the square root of the value when the square root button will be clicked.

And lastly, creating a function for the button clear, backspace, and decimal.

That’s it, you can now try to debug your simple calculator and test if the Source Code works perfectly as planned. In case it doesn’t work the way it should be, you download the working source code below.

Happy Coding : )

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. After downloading it, you will need a program like Winzip to decompress it.

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe’s, .ocx’s, .dll’s etc.)–only run source code.

How to create a simple calculator in visual basic 60

In this program I will use most of the arithmetic operators that we can use in VB. You just need few controls to make this work. You just need the following controls in your form.

How to create a simple calculator in visual basic 60

1. 3 Label controls – “1 st Value:”, “2 nd Value:”, “Answer” for the name properties that is similar above.

2. 3 text boxes – str1 for the name property of the first text box, str2 for the second, and strans for the last box.

3. 6 command buttons – name it according to the operator that you will use for the command buttons like, “cmdadd”, cmdsubtract, etc.

The codes should look like this.

For cmdadd_click() type this:

strans.Text = Val(str1.Text) + Val(str2.Text)

strans.Text = Val(str1.Text) – Val(str2.Text)

strans.Text = Val(str1.Text) / Val(str2.Text)

strans.Text = Val(str1.Text) * Val(str2.Text)

strans.Text = Val(str1.Text) MOD Val(str2.Text)

strans.Text = Val(str1.Text) ^ Val(str2.Text)

Notice that we used the “Val” to get the numerical value of the string that will be placed in the text boxes.

This is the exact code I have, I am using Visual Basic 2012 and am having trouble converting these numbers into letter grades. VB says I have no errors but when I run it, the program does not convert the numbers into letters. Any suggestions?

1 Answer 1

You swapped the high number for the B and C grades. Also, you probably want AndAlso for these checks, rather than Or . While I’m here, as a matter of good program design, you should abstract this out to a separate method. The final result:

Another thing: VB.Net has a really nice Select Case syntax you can use for this:

Finally, you could avoid a problem like swapping the number above, and as well as improve the code, by converting this to a kind of table lookup:

    1st year coding student and have a project in my visual basics class.

    Create a simple calculator that will multiply, divide, subtract and add. Thing is we are not allowed to use any decision structures or loops, only sequential style coding structure.

    I am struggling with storing, passing, and utilizing the selected mathematical operator later in the program.

    When coding equations, what data type are operators considered?

    For example in 4-1=3 is – considered a string?

    How would one go about storing this value and passing it to another section of the program then converting that to a form you could plug into a formula, all without using a decision structure or loop?

    1) User clicks on “1” button a string value of 1 is stored in a label as a string.

    2) The user clicks the the “+” button and a + is stored (not sure what data type to use here for later needs) in a label.

    3) Then user clicks “1” button a 1 is stored in a label as a string.

    4) User clicks the “=” button.

    5) The = button event handler executes code converting both the “1” strings to integer variables and the formula should represent IntResult= IntvariableOne + intVariableTwo. but since the operator may not always be + and no decision structure can be used. how can this be coded in a way that uses a variable to store the operator and complete the processing correctly in a formula?

    In the most simple terms it would be equivalent to something like: intResult= intvariableOne, Operatorvarible, intVariableTwo Like I said I am new to coding so I apologize if this is a dumb question or completely wrong approach.

    I am Tring to figure out how to make a Simple Calculator.. I have it all designed. but i have no idea where to start on the code.. can someone help me out on this. GIve me some pointers and ideas it is greatly appreciated thanks!


    Maybe you should start by designing the User interface – which I would think will consist of some buttons and a textbox.

    The start by looking at the specific button click events.

    When you click a button it will add the character to the textbox contents.

    Example in the button1 click event to add the number to the textbox contents.

    Textbox1.text = Textbox1.text & Button1.Text

    Then you will need to implement the functionality of some of the Function operator buttons – again in there click event. You will have to have a form level variable to hold the result.

    So in the + button click event you may have something like the following to convert the textbox to a double type and add it to the variable Result.

    Result = Result + CType(Textbox1.Text, double)

    Obviously other buttons such as clear to clear the textbox and result.

    These some pointers for you, you should be able to make some progress in implementing the functionality.

    Prime numbers have important applications in mathematics and computer programming. I met a mathematician on a return trip from Montreal, Canada on his way to a mathematical society meeting in the “Big Easy”. Having studied mathematics a bit (and realizing I could work for 35 years and never publish a new theorem), I asked him what was hot in mathematics. He said cryptography. Large prime numbers are difficult to calculate for super computers, which makes them great as keys for encrypted transactions. And, just recently someone asked me about calculating primes in a way that made it sound like a computer science course project. So, here we are.

    I thought of an algorithm and searched on the Internet for a quick answer. It just so happens that my algorithm is a pretty close approximation of the “Sieve of Eratosthenes”. Eratosthenes was a respected scholar and librarian in Alexandria around 250 BC. (Having to go back so far for the originator suggests to me that we would all be more productive with a lot less television. Newton discovered Calculus because there were no sitcoms.)

    A prime number is a number that is divisible by itself and 1 only. The Sieve of Eratosthenes instructs that a prime number can be derived by testing all primes less than or equal to the square root of a number. This works because all integers are a product of primes and no prime number will be divisible by a number greater than its square root without a number lesser than its square root also being a divisor. Thus if, we test all primes less than the square root of a number then we can determine if a number is prime.

    If we seed our list of primes with 2, a known prime, then we can calculate all of the primes between 2 and n. The limitation to our algorithm will be the largest number we can store of a certain type. In Visual Basic 6 we can use a Long Integer which will allow us to test all of the primes up to about 2.1 billion. The simple user interface for the sample application can be seen in figure 1. Listing 1 provides the basic solution. The solution is described after the listing.

    Figure 1: The user interface for the Sieve of Eratosthenes algorithm.

    Listing 1: A Windows application in VB6 that calculates prime numbers up to n using the Sieve of Eratosthenes.

    The sieve is comprised of thirteen lines of code on lines 13 through 25. The rest of the code supports simple user interface interactions. We initialize an array of primes with a single prime, 2, on line 66. The IsPrime test begins by assuming the Number argument is not a prime. We use a single loop, looping through all of the primes less than the square root of Number. (The loop is set up on line 17.) We invoke DoEvents to be kind to the user on line 18; this prevents the GUI from appearing to be frozen. On line 20 we update the StatusBar showing the current test value (see figure 1). On line 21 we divide the Number by the candidate known prime on line 21 and exit if Number is divisible by Primes(I), the test prime. If Number is divisible by any prime than Number is not prime. The second test evaluates the candidate prime against the square root of the Number. If we have reached the square root of the Number without finding a divisor then Number is prime. We branch out of the For Loop and return True.

    The Sieve of Eratosthenes works as long as we calculate all primes from 2 to n, which ensures that we have all possible prime divisor candidates to check.

    In visual basic, the Timer component is useful to raise an event repeatedly in our application based on the specified interval of time.

    The timer component is available with System.Timers namespace. So, to work with the timer component in our application to raise an event after a set of interval we need to import the System.Timers namespace.

    Following is the example of defining the timer object that raises an elapsed event after a set of interval in visual basic.

    Dim timer As Timer = New Timer ()

    AddHandler timer.Elapsed, AddressOf TimerEvent

    If you observe the above code, we created a timer object by using the Timer class. Here, the Interval property is used to specify the time interval to raise an Elapsed event (TimerEvent) and the Enabled property is used to specify whether the timer object should raise an Elapsed event or not.

    The AutoReset property is used to configure the timer object to raise an elapsed event repeatedly at the specified interval of time defined by the Interval property.

    In case, if we want to raise the Elapsed event only once after the specified interval has elapsed, then we need to set the AutoReset property to false .

    Visual Basic Timer Properties

    The following table lists some of the most commonly used properties of Timer class in visual basic.

    Property Description
    AutoReset It is useful to get or set whether the Timer should raise the Elapsed event only once (false) or repeatedly (true).
    CanRaiseEvents It will return a value that indicates whether the component can raise an event or not.
    DesignMode It will return a value that indicates whether the component is in design mode or not.
    Enabled It is useful to get or set a value to indicate whether the Timer should raise the Elapsed event or not.
    Interval It is useful to get or set the interval in milliseconds at which to raise the Elapsed event.

    Visual Basic Timer Methods

    The following table lists some of the most commonly used methods of Timer class in visual basic.

    Method Description
    Start() It is useful to start raise the Elapsed event by setting Enabled to true.
    Stop() It will stop raising the Elapsed event by setting Enabled to false.
    Close() It is useful to release the resources that are used by the Timer.
    Dispose() It is useful to release all the resources used by the Component.
    MemberwiseClone() It is useful to create a shallow copy of the current object.
    GetType() It is useful to get the type of current instance.

    Visual Basic Timer Example

    Following is the example of using Timer class in visual basic to execute the Elapsed events repeatedly at a specified interval of time.

    Sub Main( ByVal args As String ())

    Console .WriteLine( “Present Enter Key to Exit the Application” )

    Dim timer As Timer = New Timer ()

    AddHandler timer.Elapsed, AddressOf TimerEvent

    Private Sub TimerEvent( ByVal source As Object , ByVal e As ElapsedEventArgs )

    Console .WriteLine( “Event Raised at <0:HH:mm:ss.fff>” , e.SignalTime)

    If you observe the above example, we imported System.Timers namespace to create a timer object by using Timer class. Here, we used Interval property to specify the time interval to raise an Elapsed event (TimerEvent) and the Enabled property to specify whether the timer object should raise an Elapsed event or not.

    When we execute the above visual basic program, we will get the result as shown below.

    Present Enter Key to Exit the Application

    Event Raised at 07:48:49.274

    Event Raised at 07:48:51.275

    Event Raised at 07:48:53.275

    Event Raised at 07:48:55.275

    If you observe the result, for every 2 seconds the Elapsed event (TimerEvent) is raising and executing the elapsed event code.

    This is how we can use the timer object to raise an event repeatedly at the specified interval of time based on our requirements.

    Drop buttons onto a form. Label them “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “0”, “=”, “+”, “-“, “/”, “*”, “.”, “C” and “CE”. Optionally you can add special functions like “±” or “1/x” or “%”.

    Drop a textbox on the same form. This will be the visible “accumulator”.

    Create a handler for each of the numeral keys. If you create a “control array”, you can create one handler to handle each of the keys. The handler will decide what key was pressed. It will add that numeral to the visible accumulator.

    Create a handler for each of the four function keys and for the “=”. The function key will perform the function +, -, /, *, on the value that is in the visible accumulator with an invisible accumulator.

    For the project to succeed, you need to figure out what “states” the program is in. For example, the following states might be considered

    1. A number is being accumulated in the visible accumulator. Nothing is in the invisible accumulator.

    2. A number has been placed in the invisible accumulator and a second number is being placed into the visible accumulator.

    There are other, more subtle states. You need to identify each of them.

    Open up the CALCULATOR program that comes with Windows. Figure out how that must work. That will give you ideas on how to make the calculator work.

    I won’t write the program for you. I’ve done that for a living and they paid me a lot of money for doing it so if you wanted me to write code for you, you’d have to pay me lots of money and I would have to agree to accept it (which I won’t). However, I will give you hints and I’ll help you out, in some cases, with subroutines. (Click the “Go Advanced” button when you’re responding. You can attach a zip file containing the VB6 code).

    How To Make A Calculator In The Visual Basic Programming Language

    How to create a simple calculator in visual basic 60

    Making a calculator using Visual Basic as an application for Windows PC is simple but requires a lot of hard work, practice, and experience in Visual Basic programming and object oriented training. You need to learn and start from smaller things like ‘hello word’ programs before you can take on larger challenges.

    How to create a simple calculator in visual basic 60

    Once you have practiced enough, you can download the Microsoft Visual Studio that will help give in making the application.

    This project will give you a little taste of what computer programming is like, and show you the steps involved in creating a complete program. These instructions will lead you through the steps for creating a Visual Basic program that calculates compound interest.

    First released in 1991, Microsoft Visual Basic was a programming environment where one could build an application by visually creating the user interface first, and then adding code. In contrast, even the smallest Visual Basic basic programs could take reams of program code to write in C or C++. Visual Basic was extremely popular for business application programming. The language itself was an interpreted BASIC dialect, however speed was maintained through the use of reusable compiled libraries (DLLs and VBX controls). These however, limited application development to Microsoft Windows.

    Visual Basic easily interfaced with many database products (most notably Microsoft Access) and reporting tools (most notably Crystal Reports)

    Visual Basic 3 was the most popular version under 16-bit Windows 3.1, while Visual Basic 6 was the most popular for 32-bit Windows 95/NT and later. After version 6, Visual Basic was replaced by Visual Basic .NET, an incompatible successor.

    Release notes

    Microsoft Visual Basic 6.0, now part of Visual Studio, was the last version of the true “Visual Basic” product. It was extremely popular, and is still used in many businesses. It is the last that can create native 32-bit applications for Windows 9x and NT. The replacement product “VB.NET” requires Dot Net, and changes the core basic language in such a way that it is difficult to port VB 6 applications.

    Installation instructions

    Requires that MSIE 4 or later is installed.

    The purpose of this program is to minimize the work of all humans, which is a massive challenge. Users working on the equation would be significantly shortened by using this Basic Calculator. The machine would be able to perform operations such as addition, subtraction, multiplication, division, finding the square root of a number, etc. Quick Calculator is user-friendly and easy to use.

    Languages to be used:

    Front End: Visual is an improved version that contains enhanced features such as heritage, interface, and overloading of these features to include a solid object-oriented programming language. As a simple developer, we can now create a multi-thread, scalable system using a transparent multithread. Other recent improvements include simplified exception handling, customer interoperability, the smooth introduction of automated protection, and improved versioning support.

    Visual consists of three principal entities:

    1. Assemblies: the main deployment unit for the NET program.
    2. Modules: the areas that make up the assembly.
    3. Types: Simple units that encapsulate data and behavior.

    Hardware requirements:

    • Processor: Intel dual-core or above
    • Processor Speed: 1.0GHZ or above
    • RAM: 1 GB RAM or above
    • Hard Disk: 20 GB of hard disk or above

    Software requirements:

    • Language: Microsoft Visual Studio 2008

    Future Scope of the Project:

    • Reduction of paperwork.
    • Human initiative or Manual Labour may be significantly minimized.
    • Large operations that are conducted manually can be completed in a matter of seconds.


    1. Yes, I did leave most of the work to the reader. That was the point. This was an exercise for a class, and I am not helping them if I give them the answers.
    2. This is a tip, not and article. Tips are not intended to go into great detail.
    3. Pressing an operator completes the previous operation, not the current one. Pressing = is a noop . If you pick up a cheap calculator, you will find that this is how they work. If you press 3 × 4 + , pressing + instructs the calculator to complete the previous calculation of 3 × 4 and puts + on the operator stack. Then if you press 2 = it uses the value in the accumulator ( 12 ) and completes the next operation + 2 resulting in 14 . What the display (UI) reads at each step depends on the desired behaviour.
    4. The poster’s question was how to handle more than 2 numbers and 1 operator.
    5. No, I didn’t get bored. I took time out of my workday to answer the poster’s question. Answering the question, writing the code, and writing the article took one hour, which is one hour I don’t get paid.

I need to be able to make the program display the keys pressed by the user on the keypad (only the numbers 0 – 9) and it should also still be able to do the functions even though the numbers were inputted through the keypad and not through the buttons on the calculator, so far Ive been able to create all the functions except the square root and negative sign, i can do that on my own but I would really appreciate some help on this, I was researching and saw this function called “Keypress” but I don’t know how to use it, I just started learning VB 2 days ago, I’m surprised my teacher gave us such a difficult task in only our second meeting, but oh well what can I do. How do I go about doing this, please tell me what functions I should research on, and can you also please explain those functions so I will have an Idea on how to use them. Here is my code.

    Um. you could try the onkeypress() event handler? Just Google for number codes.

    Instead of using a calculator, use Microsoft Excel to do the math!

    You can enter simple formulas to add, divide, multiply, and subtract two or more numeric values. Or use the AutoSum feature to quickly total a series of values without entering them manually in a formula. After you create a formula, you can copy it into adjacent cells — no need to create the same formula over and over again.

    Subtract in Excel

    How to create a simple calculator in visual basic 60

    Multiply in Excel

    How to create a simple calculator in visual basic 60

    Divide in Excel

    How to create a simple calculator in visual basic 60

    Learn more about simple formulas

    All formula entries begin with an equal sign ( =). For simple formulas, simply type the equal sign followed by the numeric values that you want to calculate and the math operators that you want to use — the plus sign ( +) to add, the minus sign ( –) to subtract, the asterisk ( *) to multiply, and the forward slash ( /) to divide. Then, press ENTER, and Excel instantly calculates and displays the result of the formula.

    For example, when you type =12.99+16.99 in cell C5 and press ENTER, Excel calculates the result and displays 29.98 in that cell.

    How to create a simple calculator in visual basic 60

    The formula that you enter in a cell remains visible in the formula bar, and you can see it whenever that cell is selected.

    Important: Although there is a SUM function, there is no SUBTRACT function. Instead, use the minus (-) operator in a formula; for example, =8-3+2-4+12. Or, you can use a minus sign to convert a number to its negative value in the SUM function; for example, the formula =SUM(12,5,-3,8,-4) uses the SUM function to add 12, 5, subtract 3, add 8, and subtract 4, in that order.

    Use AutoSum

    The easiest way to add a SUM formula to your worksheet is to use AutoSum. Select an empty cell directly above or below the range that you want to sum, and on the Home or Formula tabs of the ribbon, click AutoSum > Sum. AutoSum will automatically sense the range to be summed and build the formula for you. This also works horizontally if you select a cell to the left or right of the range that you need to sum.

    Note: AutoSum does not work on non-contiguous ranges.

    How to create a simple calculator in visual basic 60

    How to create a simple calculator in visual basic 60

    In the figure above, the AutoSum feature is seen to automatically detect cells B2:B5 as the range to sum. All you need to do is press ENTER to confirm it. If you need to add/exclude more cells, you can hold the Shift Key + the arrow key of your choice until your selection matches what you want. Then press Enter to complete the task.

    Intellisense function guide: the SUM(number1,[number2], …) floating tag beneath the function is its Intellisense guide. If you click the SUM or function name, it will change o a blue hyperlink to the Help topic for that function. If you click the individual function elements, their representative pieces in the formula will be highlighted. In this case, only B2:B5 would be highlighted, since there is only one number reference in this formula. The Intellisense tag will appear for any function.

    How to create a simple calculator in visual basic 60

    Learn more in the article on the SUM function.

    Avoid rewriting the same formula

    After you create a formula, you can copy it to other cells — no need to rewrite the same formula. You can either copy the formula, or use the fill handle to copy the formula to adjacent cells.

    For example, when you copy the formula in cell B6 to C6, the formula in that cell automatically changes to update to cell references in column C.

    How to create a simple calculator in visual basic 60

    When you copy the formula, ensure that the cell references are correct. Cell references may change if they have relative references. For more information, see Copy and paste a formula to another cell or worksheet.

    A popular question on developer forums is how to create a Roman Numeral converter. It may seem to be a relatively easy task, but looks are deceiving, indeed. Today, I will show you a few different ways to create a decent Roman Numeral converter with Visual Basic.

    First, Some History

    A Roman Numeral is a number that is written in the way that the ancient Romans used to write numbers. This numeric system stayed the way of writing numbers in Europe until the Middle Ages. The Roman numerical system is composed of seven Latin letters which include: I (unus): one; V (quinque): five; X (decem): ten; L (quinquaginta): fifty; C (centum): one hundred; D (quingenti): five hundred; and M (mille): one thousand. By combining symbols, a Roman number is formed. There is no symbol for a zero, so there is also no need for zeros to keep place for other numbers. For example: A number such as 203 is written as CCIII.

    If two letters are next to each other, each letter is worth powers of ten and the second letter is worth ten times the first. The ultimate value of this letter-group, or number, equals the second letter’s value subtracted by the first letter. This means then that IX equals nine, XC is ninety, and CM becomes nine hundred.

    The Roman Numeral system is additive; this means that the numbers are simply added. For example, the number ‘IV’ means four. Talking about the Roman number four, this number is written like that for the simple reason that four or more symbols that look the same aren’t allowed to be written out. This means that you cannot have a number written as IIII—which ordinarily would mean four—but written as IV instead.

    Enough history? Okay, let me move on. Let’s create a project that can convert Roman Numerals to ordinary numbers.

    Create a new Visual Basic Windows Forms project and add one button to the form. Add a separate class. Feel free to use your own names, but remember that my names might be different than yours.

    Let me pause here and explain the methodology first.

    Man, I love patterns! If you look closely, you will see the same pattern being repeated depending on what the value of the number is. Before I get too far ahead of myself, look at the following:

    In Visual Basic, For loop is useful to execute a statement or a group of statements repeatedly until the defined condition returns true.

    Generally, For loop is useful in Visual Basic applications to iterate and execute a certain block of statements repeatedly until the specified number of times.

    Visual Basic For Loop Syntax

    Following is the syntax of defining the For loop in Visual Basic programming language.

    If you observe the above syntax, we defined For loop with different parameters. Here, the variable parameter is require in the For statement, and it must be numeric. The Data Type is optional, and it is useful to define the data type for the variable. The start and end parameters are required to define the initial and final value of a variable.

    Visual Basic For Loop Flowchart Diagram

    Following is the pictorial representation of For loop process flow diagram in Visual Basic programming language.

    How to create a simple calculator in visual basic 60

    Now, we will see how to use For loop in Visual Basic programming language with examples.

    Visual Basic For Loop Example

    Following is the example of using For loop in Visual Basic programming language to iterate or loop through a particular list of statements.

    If you observe the above code, we defined a For loop to iterate over 4 times to print the value of variable i and following are the main parts of For loop.

    When we execute the above Visual Basic program, we will get the result as shown below.

    How to create a simple calculator in visual basic 60

    If you observe the above result, For loop was executed four times and printed the variable i value four times.

    Visual Basic For Loop with Exit Statement

    In Visual Basic, using the Exit keyword, we can stop the execution of the For loop statement based on our requirements.

    Following is the example of stopping the execution of For loop using Exit statement.

    If you observe the above code, we used Exit statement to exit from For loop whenever the variable i value equals to 3.

    When we execute the above Visual Basic program, we will get the result as shown below.

    If you observe the above result, whenever the variable i value equals 3, the For loop execution automatically stops.

    This is how we can use Exit statement in For loop to terminate the execution of For loop based on our requirements.

    Visual Basic Nested For Loop

    In visual basic, we can create one For loop within another For loop based on our requirements. Following is the example of creating a nested For loop in Visual Basic.

    If you observe the above example, we created a For loop within another loop and printing the values based on our requirements.

    When we execute the above Visual Basic program, we will get the result as shown below.

    This Solution is for the “Making a difference Exercise” of chapter 4 in the textbook; Visual c# How to program 6th edition by Deitel.
    The first portion is the Program, the second portion is the needed Class;

    //Date: 4/20/17
    Creates a class called HeartRate with class attributes that include the patient’s first name, last name,
    year of birth and the current year. The class has a constructor that receives this data as parameters.
    Each attribute provides a property with set and get accessors. The class also includes a property
    that calculates and returns the person’s age (in years), a property that calculates and returns the person’s
    maximum heart rate and that calculate and return the person’s minimum and maximum target heart rates.

    The app prompts for the person’s information, instantiates an object of class HeartRates and displays
    the information from that object; including the person’s first name, last name and year of birth, then calculates
    and displays the person’s age in (years), maximum heart rate and target-heart-rate range.

  4. How to create a simple calculator in visual basic 60

    A form of visual acuity testing was employed 1000 years ago when desert Bedouins used the ability to identify double stars as an evaluation of vision. The development of the Snellen chart in the 1860s by Dutch eye doctor Hermann Snellen was an important landmark in the standardization of measuring visual acuity. Dr. Snellen also developed the “Tumbling E” chart (Random E test).

    Visual acuity measures the ability of the eye to distinguish shapes and the details of objects at a given distance (or sharpness of vision). Central visual acuity is a key sign of overall ocular function. Excellent visual acuity indicates the cornea and lens are clear, the image is clearly focused on the retina, the afferent visual pathway is functioning, and the visual cortex has interpreted received signals appropriately. The exam is performed by optometrists, ophthalmologists, opticians, technicians, nurses, and now even in households with the EyeQue Insight. The central visual acuity test is used to:

    Provide a baseline visual acuity recording
    Determine the best possible visual acuity in each eye
    Aid examination and diagnosis of refractive error
    Assess any changes in vision
    Measure the outcomes of cataract or LASIK surgery

    Snellen Test

    How to create a simple calculator in visual basic 60

    The Snellen test is a chart of letters or symbols, commonly used in schools and eye doctors’ offices. It usually includes 11 rows of capital letters, with the first line having one very large letter. Each row has an increasing number of letters that get progressively smaller in size. The individual views the chart from either 14 to 20 feet away, while sitting or standing. At an eye doctor’s office, the chart might be projected or shown as a mirror reflection. Using a mirror eliminates the need to have 20 feet of space from the patient to the chart. One eye is covered with a plain occluder, card, or tissue. Letters are read out loud with the uncovered eye, from the top of the chart down until a person can no longer accurately distinguish them. Then the test is repeated with the other eye. An easier and faster technique is to instruct the patient to read the smallest line they can see.

    Often, this results in the individual going directly to the 20/20 line and reading it correctly, saving considerable time. If a person wears distance glasses, the test is done with and without glasses. In individuals age 40 and older who wear reading glasses or bifocal spectacles, visual acuity can be measured with the near card at 14 inches, which correlates well with distance visual acuity.

    Random E Test

    This test is used by people who cannot read or by young children who don’t know the alphabet. Instead of using different letters, the “Tumbling E” eye chart uses a capital letter E facing in different directions. While looking at the letter on a chart or projection, the person states whether the E is facing up, down, left, or right. With this chart, there is a one in four chance a person can guess the direction, therefore it is recommended they correctly indicate the orientation of most letters of the same size (e.g. five out of six).

    How to create a simple calculator in visual basic 60

    Interpreting Test Results

    The top number refers to the distance in feet you sit/stand from the chart. The bottom number indicates the distance at which a person with normal eyesight can read the same line you correctly read. The line recorded is the last one in which the patient correctly reads the majority of letters. The visual acuity of the right eye is typically written above the fraction for the left eye.

    Visual acuity is expressed as a fraction (e.g. 20/20 or 20/40). A person with 20/20 vision can see what an average person can see on an eye chart when they are standing 20 feet away, which is considered normal. If a person has 20/40 vision, this means they need to be 20 feet away to see an object others can normally see from 40 feet away. After reading the chart, a person looks at the chart using different corrective lenses. The lenses are switched out in each eye until the person can see the chart clearly with both eyes.

    Visual acuity worse than 20/40 frequently results in difficulty in reading the small print. While state laws differ, visual acuity of 20/40-20/60 or better in at least one eye is generally required for driving a car. Visual acuity of 20/200 or worse in the better eye is frequently used as the parameter for legal blindness.

    Limitations of Visual Acuity Tests

    Although they are useful for assessing central visual acuity, eye charts do not determine if you have an eye disease such as glaucoma or problems with the retina. They also do not measure other vision problems such as loss of peripheral vision. However, with new technological advances, you can now track your visual acuity from home which can serve well for those in need of frequent visual acuity check-ups.

    What is the Myopia Epidemic? Is Your Child at Risk?

    In the next few pages, you’re going to create a Calculator. It won’t be a very sophisticated calculator, and the only thing it can do is add up. What the project will give you is more confidence in using variables, and shifting values from one control to another. So create a new project, call it Calculator, and let’s get started.

    Designing the Form

    Let’s design the form first. What does a calculator need? Well numbers, for one. A display area for the result. A plus sign button, an equals sign button, and a clear the display button.

    Here’s how our calculator is going to work. We’ll have 10 button for the numbers 0 to 9. When a button is clicked its value will be transferred to a display area, which will be a Textbox. Once a number is transferred to the Textbox we can click on the Plus button. Then we need to click back on another number. To get the answer, we’ll click on the equals sign. To clear the display, we’ll have a Clear button.

    If you haven’t already, create a new project. Save it as Calculator. To your new form, first add ten Buttons (You can add one, then copy and paste the rest). The Buttons should have the following Properties:

    Name: btn Plus a Number (btnOne, btnTwo, btnThree, etc)

    Text: A number from 0 to 9. A different one for each button, obviously

    Font: MS Sans Serif, Bold, 14

    Next, add a Textbox. Set the following properties for the Textbox:

    Name: txtDisplay
    Font: MS Sans Serif, Bold, 14
    Text: Erase the default, Textbox1, and leave it blank

    Three more buttons need to be added

    Plus Button
    Name: btnPlus
    Font: MS Sans Serif, Bold, 14
    Text: +

    Equals Button
    Name: btnEquals
    Font MS Sans Serif, Bold, 14
    Text: =

    Clear Button
    Name: btnClear
    Font MS Sans Serif, Bold, 14
    Text: Clear

    When your form design is finished, it might look something like this:

    How to create a simple calculator in visual basic 60

    So if you wanted to add 5 + 9, you would click first on the 5. A 5 would appear in the textbox. Then you would click the + symbol. The 5 would disappear from the textbox. Next, click on the 9. The number 9 would appear in the textbox. Finally, click on the = symbol. The 9 would disappear from the textbox, and the answer to our sum would replace it. We would then click the Clear button to clear the display.

    In the next section, we’ll make a start on the VB NET code for the all those buttons.

    In this step you’ll create the application that will be tested, also called System Under Test (SUT). The application will be a simple calculator in a C# class library.

    1- Open Visual Studio and create a new C# class library by selecting “Create a new project” from the Visual Studio startup dialog:

    > Note: Do NOT use any special characters in your project name e.g. (parenthesis). This will result in build errors from the code generated by SpecFlow.

    *Solution name automatically updates to project name, leave it as is.

    4- Rename Class1.cs to Calculator.cs and overwrite the content with the following code :

    As a few people have pointed out, there is actually nothing really wrong with this code.

    I mean, there needs to be some naming standardization, most notably any public property should be capital.

    I would also advise a backing field for each property making the constructor a bit cleaner:

    That being said from a design point of view, it is best to mirror your objects to real world objects.

    Is a PayRateCalculator actually a PayCheck ? Would it not make more sense to have a paycheck of some kind, once you have your details assigned you can return the paycheck as a separate thing?

    The means with which you generate the paycheck should stand alone from the paycheck itself, allowing the possibility in future of having multiple calculation methods or doing something interesting with the paycheck object.

    Although again, these are just design considerations as your application scales.

    There is nothing inherently wrong with your code, which is well-written, decently-named and functional.

    How to create a simple calculator in visual basic 60

    The standard naming convention for properties is PascalCase in C#.

    I try and give default “magic constants” a name. In this case I admit it’s fairly obvious however you never really know what your code will turn into. It is also good to form habits so you wont forget these things.

    You should use decimal as you are operating with currencies and pay rates. Floating point rounding can unexpectedly bite you.

    There is no way to change the _withholdingRate .

    As the PayRateCalculator only really makes sense once you have set the name, hours and payrate I’d consider removing the default constructor. Then you’d have to change the calling code to temporarily store these things before you can instantiate an instance. I’d also consider changing most of those properties to a private set . This way you can avoid getting a PayRateCalculator into an inconsistent state.

    Another programmer cannot easily figure out from just the class interface (ctor and public methods and properties) which he needs to populate in order to make sensible use of it. Taking the choice away (forcing to pass in the important properties through the ctor) makes that obvious.

    Introduction: BMI Calculator

    My name is Umair Bin Asim. I am a student of Global Perspective, doing my O levels. This project is part of an awareness campaign that me and my classmates are currently conducting. We recognize obesity as a rising problem all over the world and are encouraging people to combat obesity before it leads to a major social catastrophe. This project is one of our many awareness campaigns.

    The BMI calculator, is to allow people more ease in calculating their body mass index and determining whether or not they are obese. The calculator we’ve made is set in the standards of the american health association. The purpose of posting this is to allow people to not only make a calculator but to also allow people to modify their calculators to whatever their national standard is.

    Step 1: Creating a New Visual Studio Project

    1. open visual studio
    2. click on new project
    3. select widows form application
    4. rename the project to “BMI calculator”
    5. save the project and remember the location (i’ve saved it in a separate drive)

    Step 2: Two Sections

    there two sections in Visual studio windows form application

    1) Form1.vb [Design]

    in here you create the GUI

    in here you write your programming

    you can choose the tabs by selecting on them

    Step 3: Design the Interface (labels and Textboxes)

    in this step you need to design the graphics user interface.

    1. select labels from the toolbox available (if you cannot find the tool box press Ctrl+Alt+x)
    2. drag the label on to the form and arrange them on the right. we need three labels
    3. arrange the labels along the left
    4. click on the labels and in the properties change Autosize to FALSE, this will allow you to resize the label.

    click on the labels and in the properties change the text to “height”,”weight”,”your BMI “, respectively.

    you can also change other setting in properties such as colour and 3D effect.

    drag three text boxes from the toolbox and align them along the left parallel to the labels

    click on the textbox and in the properties change the name settings to “txtheight”, “txtweight”, “txtresults”

    you can also change other setting in properties such as colour and 3D effect.

    create a last textbox and align it on the bottom, name this text box “txtcomment”, this will give a result on the basis of the persons BMI as understanding from numbers alone may be difficult.

    changing the name is essential as we will have to call these textboxes up in our program, if you prefer to put any other name you must change the name of the referred button in the program as well. (the names are according to my program)

    Step 4: Design the Interface (buttons)

    place buttons by dragging them from the toolbox and aligning them as show in picture

    while the button is selected change the name on the button in the properties, and you can change the text setting too.

    • create a button name “btncalc”, with text “calculate BMI”
    • create a button name “btnclear”, with text “clear”
    • create a button name “btnexit”, with text “exit”
    • create a button name “btnabout”, with text “learn about us”
    • create a button name “btnhlp”, with text “need help?” (i haven’t used this and it’s been left free in case you want to add a help button)

    align the buttons in the GUI form as you see fit

    changing the name is essential as we will have to call these buttons up in our program, if you prefer to put any other name you must change the name of the referred button in the program as well. (the names are according to my program)

    Step 5: Programming Your Calculator

    Step 6: Congratulations Your Progamming Is Done

    now you can calculate your BMI and you know how to edit your software to your liking

    to play the software press the green arrow on the upper bar or simply press F5 enjoy!

    for your convenience we’ve posted our own calculator(ready made) as well as the programming(in a .txt file)

    In this article, we will create an Excel function to calculate the distance between two addresses using the Google Maps directions API. This will allow you to get the travel time between the two locations. The format of the function will be as follows: =TRAVELTIME(origin, destination, api_key) , =TRAVELDISTANCE(origin, destination, apikey) . The origin and destination will be strings, and can be either an exact address or the name of a place. In order to use the function, an API key is required. The “Getting Started” page can help you with this: Create a new project and make sure the Directions API is added.

    Step 1: Create a new macro file and add VBA-JSON

    Because the Google Maps Directions API is a JSON API, we will use VBA-JSON to make it easy to use the results from the web request. You can download the latest version from here: Download and extract the zip file. Then, open your macro file. Open the Visual Basic Editor (Alt + F11).

    How to create a simple calculator in visual basic 60Open the Visual Basic editor. If you do not have this button, ensure the “Developer” tab is enabled. Right click the ribbon, go to “Customize the Ribbon…”, and check Developer under Main tabs.

    In order to import the VBA-JSON file, go to File > Import File… (Ctrl + M). Select JsonConverter.bas . A JsonConverter module will appear in the sidebar.

    How to create a simple calculator in visual basic 60Import JsonConverter.bas using the Import File… function.

    Next, make sure the appropriate references are enabled. Go to Tools > References… In addition to the references already selected, check off “Microsoft Scripting Runtime” (for Dictionary support needed by VBA-JSON) and “Microsoft WinHTTP Services, version 5.1” (to make the HTTP request to the API). If you require support for Excel for Mac, you will need to install VBA-Dictionary from the author of VBA-JSON. More details can be found at the bottom of the project homepage:

    How to create a simple calculator in visual basic 60Please make sure the pictured references are selected.

    Step 2: Create the functions

    With the references configured, we can now write the code for the function. The code is relatively simple. It is simply takes the three parameters and formats them into a web request. The response of the web request is then parsed by VBA-JSON and the relevant variable returned. Note that the request may return multiple routes, but then function simply returns the time of the first route. The default mode is driving, but refer to the Directions API documentation for information on other modes and adjust the strURL variable accordingly.

    To insert the code, create a new module with Insert > Module. Then paste the following code:

    Save the file. You should now be able to use the functions from within Excel. Place your API key in cell A1, then try the following: =TRAVELTIME(“24 Sussex Drive Ottawa ON”, “Parliament Hill”, A1) . This returns a travel time of about 435 seconds. If you would like this to be displayed in minutes and seconds, try this function: =FLOOR.MATH(A8/60)&” minutes “&MOD(A8, 60)&” seconds” where A8 is the cell with the travel time in seconds. This prints a helpful “7 minutes 15 seconds” for the 24 Sussex example. We can also find the distance. Try the following: =TRAVELDISTANCE(“24 Sussex Drive Ottawa ON”, “Parliament Hill”, A1) . It returns a distance of 2667 meters. Convert to kilometers with this: =ROUND(A9/1000, 1)&” km” .

    Note: The Google Maps Directions API always returns distances in meters. Convert to KM or Miles as you wish. This can be done in Excel or by modifying the functions in VBA.

    How to Create a Floorplan in Excel

    Confession time: I’m a slight spreadsheet nerd. My dad worked for IBM and I remember seeing him working on spreadsheets on our home computer at a pretty young age. I got hooked in late high school/early college, creating spreadsheets for my budget, comparing prices at various grocery stores, etc. So naturally, when I started working as a school librarian, I wanted to use spreadsheets in my work there. The physical space of our library was horribly cluttered when I first got there, so I immediately started dreaming up ways of changing the space. Pretty soon, I decided that I NEEDED a spreadsheet of the floorplan of our space.

    My first couple of layout designs came out pretty bad, but gradually I started getting the hang of creating floorplans using Microsoft Excel. Now I realize that there are probably better programs out there for creating floorplans. Programs that might even be less labor intensive. But there’s actually method to my madness in using Microsoft Excel:

    1. Most reasonably tech savvy people know how to use it: A generalization yes, but you’re likely to find more people with Excel experience than with Google Sketchup.
    2. We often already have access to it: I researched interior design programs when I first started putting together my layout, and most of the good ones were pretty expensive, while the free ones didn’t give me enough customization. Most people tend to have a copy of Excel on their work or home computers, even Mac users like me.
    3. Highly customizable: There’s a lot of ways to customize your diagrams in Excel.
    1. Labor intensive to start: When you make your first floorplan, it will take a good amount of work and elbow grease. But after you do it the first time, it’s pretty easy to continue modifying it.
    2. Doesn’t cater to unusual shapes: I love our Interior Concepts Collaboration table, but it’s REALLY hard to draw that in Excel. Basic rectangles and circles are a breeze though.
    3. Previous experience in Excel is needed: This post isn’t an intro to Excel, so if you don’t know how to do things like resizing columns and inserting objects, you’ll want to learn that first.

    All this aside, I think it is worth your time to try out making a floorplan using Excel. Now I’m going to show you how I do it.

    Creating your floorplan

    1. Create a rough draft on graph paper (or sketch it out on regular paper)

    This might seem counter-intuitive, but it’s easier to sketch out your floorplan on graph paper first, and then take that information to make a spreadsheet. Grab a tape measure, and measure the boundaries of the room(s) you’re creating the floorplans for. If you have access to the blueprints, awesome! Using one square on the graph paper to represent one square foot, draw out the basic boundaries of the space. Now it’s time to put the stuff in your space 🙂

    2. Measure ALL THE THINGS!

    Measure the length and width of every table, desk, chair, storage unit, etc in your space. Write down the measurements on a notecard. For now, you don’t need to worry about exactly where they fall in the space, What you DO need are a list of how many of each item you have and what their sizes are (ie. Six 30×60 tables, Four 36×90 bookshelves, etc) Don’t worry about the height – that won’t be represented in the spreadsheet. Once you’ve got all the data written down, it’s time to transfer that to the computer.

    3. Setup your spreadsheet like a grid

    Excel spreadsheets start out with wide columns, which doesn’t work well for floor plans. I like to create a grid of squares where each square represents one square foot. That makes it the easiest for planning out the space. This website offers a great tutorial for figuring out exactly what numbers work best for you.

    4. Create the boundaries of your space in Excel

    Decide how many square feet each square on your grid will represent. I prefer 1 sq ft per square, but that’s me. Count out the boundaries of your space based on your scale and highlight those squares. Create a bold boundary around this area to help you see the scale you have.

    5 . Create fixed objects

    If there are certain elements of your space that are fixed, such as wall mounted library shelves, add them straight to the grid. For our shelves, I highlighted the areas where they are and colored those squares burgundy. This helps me to get a visual idea of where they are and it’ll be useful in the next step when creating furniture.

    6. Create and arrange your furniture items

    Using the measurements you took earlier, start to create the furniture items of your space. This can be as simple or complex as you like. Basic rectangle shapes tend to work best for most things. I like to color code my shapes in colors similar to the furniture items, as it helps me to remember what they are. Try to position the items relatively as they are now.

    7. Group items as needed

    If there’s a certain grouping of furniture that always goes together (ie. chairs at computer tables) you can group the items together using the group function in Excel. Hold down control (PC) or command (Mac) and select each of the items you want to group. Then choose group items. Now when you move one, you can move all of them

    8. Play house

    Now that you have all your furniture items in place the way your space is set up, save your file. Then save as and create a new file for experimentation and ideas. Move your furniture all over and experiment with new layouts. Create shapes for furniture items you’re thinking about purchasing and play around with your space. This is my favorite part of creating an Excel layout – it makes it so easy to experiment with new ideas.

    Welcome to Visual Calculator

    Visual Calculator for SansGUI has been created to demonstrate some fundamental capabilities of the SansGUI Modeling and Simulation Environment. This calculator has some simple arithmetic operators and functions built in. It is different from a regular calculator in that the mathematical expressions in Visual Calculator are built by the users in visual diagrams. With this, the relationship of operators and operands can be visualized. In addition to having it as a fun project, our objectives are to introduce a few useful run-time facilities in SansGUI to simulation users and some basic implementation techniques to simulation developers. The Schema Definition and the calculation engine with full source code implemented independently in both Microsoft Visual C++ and Compaq Visual Fortran are included.

    Introduction: shows how to use this environment to create visual representations of mathematical calculations that can really be computed.

    Developer’s Corner: explains how this project was created and how the class functions are implemented.

    Version 1.1 Release Notes

    A new class, Constant , is introduced in version 1.1. Similar to the Variable class, it has a Value attribute. The difference between the two is that the scope of the Value attribute is Input in class Constant , but is In/Out in class Variable . Therefore, when the user clears all the overriding values or clicks on the Reset Data button in the Run toolbar, the overriding values in the parts that are derived from class Variable will be wiped off; whereas those in class Constant derived parts will be kept intact. The examples have been modified to take advantage of the new Constant class.

    The other enhancement in this version is the algorithm of generating damped sine waves in the SineGen class. The damping factor is linearly interpolated inside within circular cycle, rather than staying constant as in version 1.0. With this enhancement, the discontinuity of the curve at the joint of two adjacent cycles is eliminated.

    Although Visual Calculator version 1.1 can work with SansGUI version 1.0, it is recommended that you upgrade SansGUI to version 1.1 to take advantage of the new features, including dynamic charting. Both Example 3 and Example 4 contain plotting of dynamic data values. The dynamic charting feature is available right away without any extra coding in Visual Calculator.

    System Requirements

    This program requires the SansGUI Run-Time Environment . The demonstration version of SansGUI ( SGdemo , available from ProtoDesign’s web site ) can be used to run the pre-built project or create new ones of your own. With the SGdemo edition, however, you cannot save your work for future access. Optionally, the SansGUI Development Environment in the Professional Edition can be used to modify the Schema Definition and extend the calculator’s capability. You are invited to make it a full-blown scientific calculator.
