You may want to take a look at Mike Asherman's error handler at http://www.ideaxchg.com/ix07/

>I trying to write a general error recovery procedure. When my VFP program encounters a situation it cannot resolve, such as inability to open a data file, I want to display a message, clean up, and return to the main screen and menu. This could occur almost anywhere in the program and at any read level.

>I have tried the following code:

>procedure AbortProc
>*- display message
>...
>*- close all tables
>close all
>*- release popups
>release popups
>*- release all user windows
>clear windows
>*- release memvars except globals and a few we need
>release all except p_*, cTitle, mainbutton
>set procedure to
>*- return to main menu
>return to master	&& AbortProc

>This seems to work most of the time, but in some situations what happens is that after returning to the main menu, when I select a menu item the program crashs. ("VFP has encountered a program and needs to shut down...") I guess I'm not cleaning up correctly, but I don't see what else to do.
