CB_SETEXTENDEDUI message

An application sends a CB_SETEXTENDEDUI message to select either the default UI or the extended UI for a combo box that has the CBS_DROPDOWN or CBS_DROPDOWNLIST style.

Parameters

wParam

A BOOL that specifies whether the combo box uses the extended UI (TRUE) or the default UI (FALSE).

lParam

This parameter is not used.

Return value

If the operation succeeds, the return value is CB_OKAY. If an error occurs, it is CB_ERR.

Remarks

By default, the F4 key opens or closes the list and the DOWN ARROW changes the current selection. In the extended UI, the F4 key is disabled and the DOWN ARROW key opens the drop-down list. The mouse wheel, which normally scrolls through the items in the list, has no effect when the extended UI is set.
