ICM_ABOUT
The ICM_ABOUT message notifies a video compression driver to display its About
dialog box or queries a video compression driver to determine if it has an
About dialog box. You can send this message explicitly or by using the ICAbout macro.

wParam = (DWORD) (UINT) hwnd;
lParam = 0;

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.
