IFullScreenVideoEx::IsModeEnabled
| Microsoft DirectShow 9.0 |
IFullScreenVideoEx::IsModeEnabled
The IsModeEnabled method queries whether a specified display mode is enabled.
Syntax
HRESULT IsModeEnabled( long Mode );
Parameters
Mode
[in] Index of the display mode to query.
Return Values
Returns an HRESULT value. Possible values include the following.
| Value | Description |
| E_INVALIDARG | Index out of range. |
| S_FALSE | The display mode is disabled. |
| S_OK | The display mode is enabled. |
Remarks
The Full Screen Renderer supports a static set of display modes. By default, every mode is enabled. You can enable or disable a display mode by calling the IFullScreenVideoEx::SetEnabled. The IsEnabled method retrieves the current setting for the specified mode.
The video card on the user's system might not support every mode. The Full Screen Renderer will not use a mode that the video card does not support, even if that mode is enabled. To determine whether the card supports a particular mode, call the IFullScreenVideoEx::IsModeAvailable method. If a mode is disabled, the Full Screen Renderer will not use it, even if the card supports it.
Display modes are indexed from zero. The IFullScreenVideoEx::CountModes method returns the number of modes.
Requirements
Header: Declared in Amvideo.h; include Dshow.h.
Library: Use Strmiids.lib.
