CBaseWindow.InitialiseWindow method
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 InitialiseWindow method initializes the window.
Syntax
virtual HRESULT InitialiseWindow(
HWND hwnd
);
Parameters
-
hwnd
-
Handle to the window.
Return value
Returns S_OK.
Remarks
By default, this method retrieves a handle to the window's device context (DC) and creates a compatible memory DC. If the value of the CBaseWindow::m_bDoGetDC flag is FALSE, however, this method does not retrieve the device contexts. The memory DC is useful for selecting bitmaps before blitting them to the window.
The CBaseWindow::DoCreateWindow method calls this method.
