CBaseWindow::OnClose (Windows Embedded CE 6.0)
1/6/2010
Handles the WM_CLOSE message.
Syntax
virtual BOOL OnClose( );
Parameters
None.
Return Value
None.
Remarks
The default behavior for this member function is to hide the window.
A derived class should not destroy the window when it receives a WM_CLOSE message but should send an EC_USERABORT notification to the filter graph manager.
This will have the playback stopped, and in some cases will also have the filters disconnected and released.
It is only when the filter that owns the window is finally released (that is, destroyed) that the derived class should destroy the window (using CBaseWindow::DoneWithWindow).
