thank you,
but what i mean is:
i have 2 apllication which is built in VFP.
one is Main.exe ( List Of All Module )the other is Invoice.exe ( One Of The Module )
In Main.Exe File there is a button to run invoice.exe ( do invoice.exe ).
after i exit the invoice.exe it turn back to main.exe.
but the invoice.exe doesn't really exit. because i try to copied newer invoice.exe, file access is denied ( main.exe is still open ). if i open and close this several time the error message is "Not Enough Memory", it means the application is still open.

my question is, how to clear the invoice.exe from memory ?
i only use command thisform.release for exit button in every module.
because if i issue quit, error message Cannot Quit Visual FoxPro is appear.
one more, how to avoid error message Cannot Quit Visual FoxPro?
i already place on shutdown quit. because i doesnot have read events.
so my logic in main.exe is
1. do form main
2. on shutdown quit
3. _screen.release

and in invoice.exe is :
1. do form invoice
2. _screen.release
