Yes. We need further information. Lot's more:
  1. What is the device? if you want device drivers, you might need C
  2. What is the message? you mentioned a status change, but can you give more detail about the message?
  3. What is the specified window? In particular, is it a stand-alone application or a child window of some application?
  4. Are you using Tk? ActiveState? How is this window created?
Something about this problem smells very Visual C++ to me, but I can't discern that yet . . .
