This method changes the style parameters for the video window.

Syntax 

HRESULT put_WindowStyle(
  long 
WindowStyle
);

Parameters

WindowStyle

[in] Set of flags that matches a subset of the flags that can be set by the GWL_STYLE value of the Win32 GetWindowLongfunction.

Return Value

Returns an HRESULTvalue.

Remarks

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 GetWindowLongfunction and therefore must be treated with care.

Be sure the current styles are first retrieved, and then the necessary bit fields are added or removed.

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

Do not use this method to affect the window size. For example, if the window is minimized, do not set the WS_MAXIMIZE style; doing so causes unpredictable results.

Instead, use the IVideoWindow::put_WindowStatemethod for maximizing or minimizing the window.

Any of the following styles return E_INVALIDARG:

  • 50WS_DISABLED

  • WS_HSCROLL

  • WS_ICONIC

  • WS_MAXIMIZE

  • WS_MINIMIZE

  • WS_VSCROLL
