Access to DigiTV's internal data and functions is granted to 3rd-pary applications via the Windows messaging interface. When using this interface (ie SendMessage, PostMessage etc) it is important for most of the messages to be directed to the currently active DigiTV window.
DigiTV assigns a window to each connected tuner and simply activates and shows the window that contains the currently viewed device. It is important that the user ascertain which window is the active one before sending any messages so that they are directed to the DigiTV instance currently in view. To do this, use the 'Get Active HWND' message described below.
