    Application.AddmessageFilter

    Hi
    I want to reroute messages with a certain code to a specific control.

    I need to intercept those messages at Application level since the main
    window doesn't catch a third party ActiveX. It is done correctly with my
    IMessageFilter.

    From there I would like to create (and SendMessage) a new message with same
    parameters except the Handler. The problem I have is to get the main window
    handler from inside IMessageFilter process.

    Any short example would be very appreciated!

      Philippe,

      You should be able to change the HWnd property of the structure to the
      handle of the window you want to route the messages to. Since the
      PreFilterMessag e method takes the structure by ref, any changes you make to
      it will stick after the method exits.
