Place a hook in a .DLL.
Below is an example which monitors mousemoves, independent of which program
is on top. Since the time in the hook procedure must be as short as
possible, an event semaphore is used to signal back to the main program,
which takes the actions:

#define SEM_MOUSEMOVE       "\\SEM32\\MOUSEMV"  

// In e.g. HookDll.Dll

/*****************************************************************************
  Hook which monitors mouse moves
 ****************************************************************************/
BOOL _export EXPENTRY RecordHook(HAB hab, PQMSG pqmsg, USHORT fs)
{
  static int    Count;
  USHORT        ErrorFlag;
  static HEV    SemMouseMove;
  
   if(pqmsg->msg == WM_MOUSEMOVE)
   {
       Count++;
       if(Count==25)    // Wait for 25 mousemove events
       {
            Count=0;            
            ErrorFlag=DosOpenEventSem(SEM_MOUSEMOVE,&SemMouseMove);
            if(!ErrorFlag)
            {
                ErrorFlag=DosPostEventSem(SemMouseMove);
                ErrorFlag=DosCloseEventSem(SemMouseMove);
            }
       }
   }
   return(FALSE);   // Operation has ended, so originator may continue
}

 // In the main program

 MODULE         ModuleHandle;   // Handle for input hook

 DosQueryModuleHandle("HookDll.dll",&ModuleHandle);
 // Set an input hook
 WinSetHook(hab, NULLHANDLE, HK_INPUT, (PFN)RecordHook, ModuleHandle);
  ... (and an WaitEventSem() in a seperate thread)

Bye, Johan.
