SYMPTOMS
When you type the Suspend command in an On Shutdown procedure, the following error message appears:

CANCEL or SUSPEND is not allowed.

In order to quit Visual FoxPro, the On Shutdown command must be cleared by typing the "ON SHUTDOWN" (without quotation marks) command in the Command window.



CAUSE
This behavior is by design.



RESOLUTION
Place the Suspend command in an event that occurs before Visual FoxPro actually begins to shutdown, as in the Destroy event of a form.



MORE INFORMATION
When you exit Visual FoxPro, you trigger the On Shutdown command. Once Visual FoxPro begins removing itself from memory, you cannot type the Suspend command.

Steps to Reproduce Behavior
 Create a program called Test.prg.  Type the following two lines of code: ON SHUTDOWN SUSPEND QUIT  Run the program and the error message appears. Select Cancel from the error dialog. Now when you try to close Visual FoxPro the error message will appear.  Type the following command in the Command window and press ENTER: ON SHUTDOWN Now you will be able to close Visual FoxPro. </ol>
