ICM_CONFIGURE

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

Notifies a video compression driver to display its configuration dialog box or queries a video compression driver to determine if it has a configuration dialog box.

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

hwnd

Handle of the parent window of the displayed dialog box.

You can determine if a driver has a configuration dialog box by specifying

- 1 in this parameter. The driver returns ICERR_OK if it has a configuration dialog box or ICERR_UNSUPPORTED otherwise.

This message is different than the DRV_CONFIGURE message used for hardware configuration. The dialog box for this message should let the user set and edit the internal state referenced by ICM_GETSTATE and ICM_SETSTATE. For example, this dialog box can let the user change parameters affecting the quality level and other similar compression options.
