Brent,

This message is recieved by the VFP ON SHUTDOWN handler
on shutdown clear events && set up the shutdown handler

_screen.BackColor = 255
read events && go into the event loop

* this code won't execute until the window X button is clicked or closed from the taskbar button

_screen.BackColor = rgb( 0, 0, 255 )
Messagebox( "on my way outta here" )

on shutdown  && you have to clear the shutdown handler out of the system

_screen.BackColor = rgb( 0, 255, 0 )
return && back to the O/S we go
>I am trying to retrieve the wParam from the tagMSG structure of Windows API GetMessage to detect the SC_CLOSE value sent when the user selects "Close CtrL+F4" from the Windows system title bar menu. However, I can not detect any form event that fires when the user opens that menu, scrolls down to the close option, and presses the "Enter" key.
