Hi AndersCarlsson,
       You have to set windows hook for mouse.

Create a dll, and write this code into it,
LoadTheDll from your application.

The code for setting up the hooks will look like this:

hhookMouse = SetWindowsHookEx(WH_MOUSE,
   (HOOKPROC) MouseFunc,  hInstance, 0);

…which will cause the following hook function to be called:

LRESULT CALLBACK MouseFunc(int nCode, WPARAM wParam, LPARAM lParam)
{
if ( nCode >= 0 )
         return 1;
else
   return(CallNextHookEx(hhookMouse, nCode, wParam, lParam));
}

Don't forget to unhook your hook before you exit by calling the following:

UnhookWindowsHookEx(hhookMouse);

GOOD LUCK
