PRB: Selecting Cancel Cancels User Code But Not Form Execution

Article ID: 130342

APPLIES TO

This article was previously published under Q130342

SYMPTOMS

The form runs and appears even though you clicked Cancel in the Program Error dialog box. The form and all objects are not removed from memory.

CAUSE

The Cancel button is supposed to cancel running code only. This is by design. The form is not code, so clicking Cancel has no affect on the form. All Cancel is supposed to do is cancel all the procedures, methods, and events currently in the call stack. It is aware of the existence of objects.

WORKAROUND

If you want to kill the object upon an occurrence of a program error, you can suspend the program, release the object, and then cancel the program.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a new form.
  2. In the LOAD EVENT for the form, type ?MYTEST1() on one line, and ?MYTEST2() on the second line. (intentional errors)
  3. Open the Debug window from the Tools menu.
  4. Add _SCREEN.ACTIVEFORM to the Debug window.
  5. Run the Form.
  6. When the program error dialog appears, click the Cancel button. Notice that the user-defined code in the Load method is canceled. The second line is not executed, but the form object is created and displayed.
