[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 DoGetWindowStyle method retrieves the current normal or extended window styles.

Syntax

HRESULT DoGetWindowStyle(
   long *pStyle,
   long WindowLong
);

Parameters

pStyle

Pointer to a variable that receives the style information.

WindowLong

Value specifying which styles to retrieve. Must be one of the following:

Label	Value
GWL_STYLE	Retrieve the window styles.
GWL_EXSTYLE	Retrieve the extended window styles.

Return value

Remarks

This member function calls the Win32 GetWindowLong function to retrieve the window style. It is called by the CBaseControlWindow::get_WindowStyle and CBaseControlWindow::get_WindowStyleEx member functions.
