long *


Automation Boolean flag (0 is off, –1 is on).

Return Values

Returns an HRESULTvalue.


This member function implements the IVideoWindow::get_AutoShowmethod. 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_Visibleor CBaseControlWindow::put_WindowStatewith the appropriate parameters.

This member function is meant to be called by external objects through the IVideoWindowinterface, and therefore locks the critical section to synchronize with the associated filter. Call the CBaseControlWindow::IsAutoShowEnabledmember function to retrieve this property if you are not calling from an external object.
