ICAbout

The ICAbout macro notifies a video compression driver to display its About dialog box. You can use this macro or explicitly call the ICM_ABOUT message.

DWORD ICAbout(
 hic,   hwnd  );

Parameters

hic

Handle of the compressor.

hwnd

Handle of the parent window of the displayed dialog box.

You can also determine if a driver has an About dialog box by specifying -1 in this parameter, as in the ICQueryAbout macro. The driver returns ICERR_OK if it has an About dialog box or ICERR_UNSUPPORTED otherwise.

Return Values

Returns ICERR_OK if the driver supports this message or ICERR_UNSUPPORTED otherwise.
