I know Minimize all applications on a computer.
VFP coding,
#Define KEYEVENTF_KEYUP 0x2
#Define VK_LWIN 0x5B

DECLARE keybd_event IN Win32API ;
INTEGER nVirtualKey, ;
INTEGER nScanCode, ;
INTEGER nFlags, ;
INTEGER nExtraInfo

= keybd_event(VK_LWIN, 0, 0, 0)
= keybd_event(77, 0, 0, 0)
= keybd_event(VK_LWIN, 0, KEYEVENTF_KEYUP, 0)

But, I don't know how to Minimize my application on a computer.
the other applications is not Minimize on a computer.
