The only way to do that is if the DLL has its own HWND. Even then, the application, not the DLL, will likely be in control of the message queue for the HWND since HWNDs are tied to threads, not modules. If the application thread does not have a message queue, the HWND will not be able to receive messages at all. In which case, the only way for the DLL to receive messages is if the DLL runs the HWND in its own worker thread inside the DLL. What EXACTLY are you trying to accomplish in the first place? Can you provide an example? Gambit
