Without understanding how your application is structured I can't answer your question.

I'm not certain what process you mean by the user logout. You mean when they quit the application altogether? Or are you talking about if the login fails?

If you're talking about if the login fails you'd do something like this:

< set up environment >

DO FORM myloginform TO lSuccess
IF m.lSuccess
* Continue running application
ENDIF

RETURN

With this structure you can return a value from the UnLoad event of the form and it will be stored in lSuccess.

If you have other questions, I need further clarification.
