The get_AutoShow method retrieves the current AutoShow state flag.
HRESULT get_AutoShow( long *AutoShow );
Pointer to an Automation Boolean flag (0 is off, 1 is on).
Returns an HRESULT value.
This member function implements the IVideoWindow::get_AutoShow method. This property simplifies window display access for applications. If this is set to 1 (on), the window, which is typically hidden after connection of the filter, will be displayed automatically when the filter pauses or runs. The window should not be hidden when the filter stops, however. If this parameter is set to 0 (off), the window is made visible only when the application calls CBaseControlWindow::put_Visible or CBaseControlWindow::put_WindowState with the appropriate parameters.
This member function is meant to be called by external objects through the IVideoWindow interface, and therefore locks the critical section to synchronize with the associated filter. Call the CBaseControlWindow::IsAutoShowEnabled member function to retrieve this property if you are not calling from an external object.
