CBaseControlWindow.get_Height 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 get_Height method retrieves the current window height.
Syntax
HRESULT get_Height(
long *pHeight
);
Parameters
-
pHeight
-
Pointer to the current window height, in pixels.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
The window has a position on the desktop. This is expressed in pixels by four coordinates (left, top, right, and bottom). Interfaces that are automated by OLE typically express this position through left, top, width, and height; this is the convention used in DirectShow. All coordinates are expressed in pixels, and changing any coordinate will update the window immediately.
Setting the left or top coordinates moves the window left or up, respectively; these coordinates have no effect on the width and height of the window. Likewise, setting the width and height does not affect the left and top coordinates.
