Step-by-Step Example

  1. Create a new form.
  2. Place a command button (Command1) on the form, and add the following code to its Click event:
       lcTemp=ThisForm.gcCurrentclk
       &lcTemp
  3. Place an Option Group on the form, and add the following code to its Click event:
       IF This.Value=1
         ThisForm.gcCurrentclk="ThisForm.Click1"
       ELSE
         ThisForm.gcCurrentclk="ThisForm.Click2"
       ENDIF
  4. Create a new form property called gcCurrentclk, and assign ThisForm.Click1 to gcCurrentclk.
  5. Create a new Form method called Click1, and place the following in the Form.Click1 method:
       WAIT WINDOW "Click #1"
  6. Create a new method called Click2, and place the following code in the Form.Click2 method:
       WAIT WINDOW "Click #2"
  7. Run the form.
The option group determines which Click method for the command button will execute.

NOTE: The Click event for the command button does not have to be a method of the current form. For example:
gcCurrentclk="DO myprog.PRG" would execute a program.
gcCurrentclk="oMyclass.Click1" would execute a method of an external class.
gcCurrentclk="WAIT WINDOW" would execute a wait window.
