How To Create a Calculator in D365 F&O - Part 2 ( Adding X++ Programming Functionality )

Building a calculator is a great project, especially if you have just started learning Dynamics 365 Finance and Operations Technical. It is quite simple for people of any skill level. This project covers the interactions between UI Design and Programming Functionality.

To get started, you need to consider the basic functionalities of a calculator. They include addition, subtraction, multiplication, division, delete, all-clear, and of course, the ability to use decimal numbers in performing these operations. But here we simply describe the basic four operations addition, subtraction, multiplication, and division.

If you are a beginner use Microsoft's free VM, where you can access both the Technical and Functional environments.

In the previous article, I already explained the UI Design process. In this article, I will explain to you how to add Programming Functionality for functioning the basic functionalities of a calculator like addition, subtraction, multiplication, and division by using X++ programming. 

1. Adding Programming Functionality to the "Addition" Button

For this expand the Addition button and right-click on Methods. Select Override and click “clicked” as shown in the figure.

Write the code In the newly opened window. Here we have declared one integer variable to hold the result of the calculation.

2. Adding Programming Functionality to the "Subtraction" Button

For this expand the Subtraction button and right-click on Methods. Select Override and click “clicked” as shown in the figure.

Write the code In the newly opened window. Here we have declared one integer variable to hold the result of the calculation.

3. Adding Programming Functionality to the "Multiplication" Button

For this expand the Multiplication button and right-click on Methods. Select Override and click “clicked” as shown in the figure.

Write the code In the newly opened window. Here we have declared one integer variable to hold the result of the calculation.

4. Adding Programming Functionality to the "Division" Button

For this expand the Division button and right-click on Methods. Select Override and click “clicked” as shown in the figure.

Write the code In the newly opened window. Here we have declared one integer variable to hold the result of the calculation.

5. Run the Project

In Solution Explorer, right-click on the calculator form and click on “Set as Startup Object”. In the toolbar, select Build and click Build Solution. Finally, In the action pane, click on “Start”. A new browser window should open with your calculator.

Now  Calculator Project is over. Try to share this simple project with your friends, who are looking for a career in d365.

Happy Coding with D365Snippets.
