Well, as the above article explains - to set a global hook (i.e. one that is notified about every message sent to any window), implement the hook proc in a DLL and call 'SetWindowsHookEx()' with the DLL' module handle and a NULL thread ID. In pseudocode, that would be
HINSTANCE hInst = LoadLibrary("myhook.dll");
HOOKPROC pProc = GetProcAddress(hInst,"MyHo
SetWindowsHookEx(WH_GETMES
As JKR told you can get all MSg for the associated window and then you can refine the message from the message queue. BUT If SetWindowHookEx last parameter is 0 , it will be hooking the message for all of the windows currently running. If this parameter is zero, the hook procedure is associated with all existing threads running in the same desktop as the calling thread.
So their you can put the thread id for your "single external process"

You can do that using a WH_GETMESSAGE hook that filters for that mesage. See http://msdn.microsoft.com/
