QUESTION:
When the user exits my application I would like to bring a messagebox to the screen in which I tell them to make a backup frequently. What is the right place in the code where I can do this?
ANSWER:
Use the procedure Exit_Application at the desktop level and call the messagebox WinAPI function via the procedures info_box or stop_box.
Place the following code at the desktop object (above Start_Ui)
Procedure Exit_Application DESKTOP
Boolean bExit
Get Exit_System_Confirmation To bExit
If (bExit) Begin
Send Info_Box "Please frequently make backups of your data"
Abort
End
End_Procedure // Exit_Application
The augmented message will first try to execute a confirmation question in which the user can confirm the exit. If they choose YES to exit the application, the boolean variable bExit will be TRUE and the user will be informed to frequently make backups.
Because the default behavior of the exit_application method is to cancel the application, you need to place an ABORT statement in the procedure as shown above.
