Getting Started With. NET 5. Getting Started with ML. NET Core.Creating a Simple Calculator is a good point to start learning. This project is done using Visual Studio Community You can download and install it from above link.
You have to install at least.
Net Desktop Development Environment to continue with this project. Click on create project and select Windows Form App. Enter the name of the project, location and click OK to create your project. You might have notice that at the Top of the form it still shows Form1.
We can change it by changing the Text property of the form. As we have created the user interface next thing we have to do is to write some code. Double click on btnAdd to open the code editor.
You can add above code inside public partial class frmCalc. This will take the numbers entered into two text boxes, txtNumber1 and txtNumber2, and convert them from string type to double type.
Then it will add those two numbers and store in the variable dblAnswer. After that it will change it back into a string and assign as the Text value of txtAnswer text box. If you have done everything correctly it should show the answer in txtAnswer. Now double click on each button and add the following code at appropriate places.
Whole code is included for your convenience. Code for click event of btnSub,btnDiv and btnMulti does the exact same thing as that of btnAdd except they will subtract,divide and multiply the two numbers respectively. Code of the btnClear click event will clear the text of all 3 text boxes and change the values stored in all three variables to zero.
This simple calculator has lot of room to improve. For example if you enter some letters instead of a number it will stop working and show an exception. We will improve this calculator in the next article.

This app is capable of performing addition, subtraction, multiplication as well as division.
View All. Vishal Prajapati Updated date, Nov 06 Press OK. Perform some changes in properties as shown in figure. Step 4 Now, we start working with the display, usually when the calculator starts it should display the number 0. In our case it does not. So we modify the Text Property and write 0 in that. The second thing to note is that the number is aligned to the left, while calculators align the number to the right.
Search for the TextAlign property and change it to Right. This is what the window will look like. Step 5 From the tool box window, drag and drop a Button onto the form. Change its Name property to n1. This will help us identify which number was pressed. Change the backcolor property for the button.
After the color changes, we will modify the text that the button is displaying, so change the text property into 1. Go to the font property, and set its font to courier new, and size to 16 for example. Now we can repeat the same operation to all the other nine buttons, or we can just copy this button and get the same result quickly.
Just hold the ctrl key and drag the control. Change the names of the buttons or you can leave them as they are and skip this part. The names will continue to be n2, n3, n4, n5, n6, n7, n8, n9, and n0. The window should look like this. Step 6 Double click the button n1 to go to its event. It tells you that it get executed when the button whose name n1 is clicked by the user. Write down the code to have it like this:.

They follow the same steps that are mentioned above. You can now use this as a calculator to make calculations on anything you want. The purpose of this project was to inform users who have no programming experience how to make a simple program.
Thank you for taking the time to make this project. If you accidentally double click a tool while moving it from the toolbox Visual Studio will automatically take you to the coding tab, and create a section for coding the element you double clicked. It is recommended to delete this section of code that was accidentally created, as it is junk code that does nothing. To return back to the form design tab, simply click the Form Design tab. Introduction: Visual Basic Calculator. Important Note: These instructions assume you already have Visual Studio installed and open.
Your User Interface where toolbars are placed my look different from the instructions. These instructions will not address how to make changes to the User Interface. Making your User Interface look like the provided pictures is not necessary, but will be helpful.
If you make a mistake, i.This Instrucable will guide you through creating a basic calculator application in C using Microsoft's Visual Studo development software. Visual Studio is a form of development software made by Microsoft to help developers create programs more easily. It is free and can be downloaded on their website. What you will need: A computer running Windows 7 or higher About 30min - 1hr of free time Possibly a scratch sheet of paper for understanding logic.
If you are familiar with the Java programming language, C functions very similarly. The syntax is just slightly different. Don't worry if you aren't familiar with programming. This Instructable will guide you through the entire process. All you need are some problem solving skills! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson. After downloading and installing, run Visual Studio so it is open on your computer. At the welcome screen, click "New Project Next, select "Windows Forms Application" in the right column and name your project in the name field below. I have named mine "Calculator," but choose any name you like. After completing all of the above, Click "OK" and let Visual Studio build the shell for your program.
When finished, your screen should look like the last image above. Click Save All the triple save icon on top of the screen and move on to step 2! This step will help you create an intuitive calculator design for your users. Select the "Form1.
This Form is the window that will display when your program is run. Clicking the green arrow in the toolbar on top of the screen will run the program as an application opening it in a new window. Try it. Close the new window with the X when you are done. The Toolbox menu allows you to add new items like buttons to your interface, while the Properties menu allows you to change the specifics of your currently selected item on the screen.
They can be placed wherever the programmer desires by clicking and dragging around the screen. If they are not visible, open the View menu, and choose "Toolbox" or "Properties Window.
Position them around the Form by clicking and dragging. Saves on clicking and dragging! Select a button.In this part we will see how the code works and then try to improve some functionalities of it. You can read more about this method here. In this example we are taking the value of the Text property of the button which is a string and converting it into a double using the Double.
Parse method. Now as we have calculated the answer we have to display it in the txtAnswer TextBox. We can do this by assigning value of dblAnswer to Text property of txtAnswer.
But to do that we have to first convert double into a string. This method is used to convert a number to its string representation. We use this method to convert the calculated answer to a string and assign it to the Text property of txtAnswer. Code line 6. Functionality of the above code is similar to that of Add button event.
Only difference is when calculating the answer we subtract dblNumber2 from dblNumber1 and assign it to dblAnswer Code line 6. Same as above but dblNumber1 divide by dblNumber2 and dblNumber1 multiply by dblNumber2 assigned to dblAnswer in each case.
When you click this button you rest everything. You might have notice that the label lblOperation have a question mark on it.
