CBaseControlWindow.put_AutoShow method

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The put_AutoShow method sets the AutoShow state flag.

Syntax

HRESULT put_AutoShow(
   long AutoShow
);

Parameters

AutoShow

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

Return value

Returns an HRESULT value.

Remarks

This property simplifies window display access for applications. If this is set to 1 (on), the window, which is typically hidden after the filter is connected, will be displayed automatically when the filter pauses or runs. The window should not be hidden when the filter stops, however. If this 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.
