ICM_CONFIGURE
The
ICM_CONFIGURE message 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. You can send this message explicitly or by
using the ICConfigure
macro.
ICM_CONFIGURE
wParam = (DWORD) (UINT) hwnd;
lParam = 0;
Parameters
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, as in the ICQueryConfigure macro.
Return Values
Returns
ICERR_OK if the driver supports this message or ICERR_UNSUPPORTED otherwise.
Remarks
This message
is different from 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 the ICM_GETSTATE and ICM_SETSTATE messages. For example,
this dialog box can let the user change parameters affecting the quality level
and other similar compression options.
