Create and test an event handler

An event handler is a subroutine that runs in response to an event. Events can be raised from the display itself or from objects in the display. You can create an event handler for a

 display and test the event from the VBA IDE.
To create and test an event handler:
  1. In the
    Microsoft
     VBA IDE, in the code window, type the code for the event handler between the
    Sub
    and
    End Sub
    statements, .
  2. Select
    File
     >
    Save
    , to save display with the subroutine.
  3. To test the event handled, select
    Run
     >
    Run Sub/User Form
    . When the event is fired, the code will run.
  4. In the
    Graphics
     editor open the display for which you are going to write display code.
Remarks
  • When you type a period after a variable name in a statement, the VBA editor displays its properties, methods, and events. Double-click an item in the list to select it, or type the first few characters of the name and then press the comma, space bar, Enter, or close parentheses key.
  • Type a single quote at the beginning of a line to add a comment to code. Everything from the quote to the end of the line is ignored.
  • To add a subroutine or function, on the VBA menu, select
    Insert
     >
    Procedure
    , which opens the Add Procedure dialog box where you specify the Name, Type, and Scope for the procedure.
