System-wide Hotkey VK_SNAPSHOT

[AUGE_OHR]

hi,

i want to re-direct "Print Screen" Key.

this is easy for "own App" but what about System-wide
i like to watch if "Print Screen" Key is press ... how

hi,

i got it run this Way

Code: Select all

   HMG_CallDLL( "User32.DLL", DLL_OSAPI, "RegisterHotKey",Form_1.HANDLE,1,0,VK_SNAPSHOT)
   CREATE EVENT PROCNAME PrtScr_Detect() HWND Form_1.HANDLE STOREINDEX nIndex
   EventProcessAllHookMessage( nIndex, .T. )

   
Procedure On_Release
   HMG_CallDLL( "User32.DLL", DLL_OSAPI, "UnregisterHotKey",Form_1.HANDLE,1)
Return

FUNCTION PrtScr_Detect()
LOCAL nHWnd   := EventHWND()
LOCAL nMsg    := EventMSG()
LOCAL nWParam := EventWPARAM()
LOCAL nLParam := EventLPARAM()
LOCAL nMask, cDevice := ""

DO CASE
   case nMsg == WM_HOTKEY
      DO_SnapShot()
ENDCASE
RETURN NIL

but now it will "always" go to DO_SnapShot() when "Print Screen" is press ...
so i have to look for other Hotkey

i don`t include my Icon in *.RC so fill it with your Icon
change Crypt Key in Setup.PRG ...

you can define any VK Key with RegisterHotKey()
HMG does not use F12 ...
