IVideoWindow::put_AutoShow (Windows CE 5.0)
This method determines whether the window will be automatically shown.
HRESULT put_AutoShow(longAutoShow);
Parameters
AutoShow
[in] OATRUE (–1) means the window is visible when the state changes.OAFALSE (0) means the window remains hidden until explicitly shown.
Return Values
Returns an HRESULT value.
Remarks
Many simple applications require a displayed window when a filter graph is set to the running state.
AutoShow defaults to OATRUE so that when the graph changes state to paused or running, the window is visible (it also is set as the foreground window). It will remain visible on all subsequent state changes to paused or running.
If you close the window while the stream is running, the window will not automatically reappear.
If you stop and restart the stream, the window will automatically reappear.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.
