PRB: RETRY Command in Method Causes Visual FoxPro to Quit

ID: Q142736

3.00 3.00b WINDOWS kbprg kbprb

The information in this article applies to:

Microsoft Visual FoxPro for Windows, versions 3.0 and 3.0b

SYMPTOMS

An "ON ERROR <object>.<method>" command is used to trap for an error. The ON ERROR command calls a method of an object. Inside the method, RETRY will trigger a "Mismatched pushjmp/popjmp call" error, which is not listed in the Help File. After you click OK, Visual FoxPro quits.

WORKAROUND

Do not call a method from an ON ERROR command. Call a program file instead.

STATUS

Microsoft is researching this behavior and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a new form.

2. Add the following code to the form's Load event:

      ON ERROR _Screen.Activeform.Mymethod

3. Create a new method of the form called Mymethod, and type the following

   code into it:

   PUBLIC obj1
   obj1=_Screen.Activeform
   RETRY

4. Place a command button on the form, and enter the following code in its

   Click event:

   obj1.Caption="Fox"

5. Run the form, and click the command button. The Error "Mismatched'

   pushjmp/popjmp call" is triggered. Inside the help for the error is the
   message "The topic does not exist. Contact your application vendor for
   an updated Help File (129)."

6. Click OK, and Visual FoxPro quits.
