Select five BUTTONS with values , - , X , / and Result.

Change the Name property of BUTTON to Add, - to Subt, X to Multiply, / to Divide and Result button to Result.

Now that the form is ready. Lets create the .bas file by creating the add_click , subt_click etc subroutines by right clicking on the button form fields selecting the script wizards and selecting OnClick option. The first time you do this a dialog box appears, asking you if you wish to create a new bas file. Select ok. Notice that a new .bas gets created with the same primary name as the .txt file. This file contains all the subroutines you will create. 字串2
