IVideoWindow::put_WindowStyleEx

  • Article

This method sets the style of the control window.

HRESULT put_WindowStyleEx(
  long pWindowStyleEx
);

Parameters

  • pWindowStyleEx
    [in] Value that specifies the style of the control window.

Return Values

Returns NOERROR.

Remarks

This method uses EX window styles. For a complete list of extended window styles, see the CreateWindowEx function in the Win32 SDK.

Use this property to change the overall style of the video window; for example, to remove the border and caption areas of the video window. It is a fairly thin wrapper on top of setting the GWL_STYLE value of the Win32 GetWindowLong function and therefore must be treated with care. In particular, ensure that the current styles are first retrieved, and then the necessary bit fields are added or removed.

Do not use the following window styles because they are not validated:

  • WS_DISABLED
  • WS_HSCROLL
  • WS_ICONIC
  • WS_MAXIMIZE
  • WS_MINIMIZE
  • WS_VSCROLL

With some exceptions (noted here), the acceptable flags are the same as those allowed by the Win32 CreateWindow function.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
