    Tabbing is provided by the dialog manager, not the Window manager. Therefore, to get tab handling, you need to call IsDialogMessage in your message loop with the hwnd of your window:
    Code:
        /* Run the message loop. It will run until GetMessage() returns 0 */
        while (GetMessage (&messages, NULL, 0, 0))
        {
            if (!IsDialogMessage(hwnd, &messages))
            {
                /* Translate virtual-key messages into character messages */
                TranslateMessage(&messages);
                /* Send message to WindowProcedure */
                DispatchMessage(&messages);
            }
        }
    I think we have discussed this before, so you might also try a board search and check the documentation for IsDialogMessage.
