Routine Description:

    Call back used to remove the "?" from the wizard page.

Arguments:

    hwndDlg - Handle to the property sheet dialog box.

    uMsg - Identifies the message being received. This parameter
            is one of the following values:

            PSCB_INITIALIZED - Indicates that the property sheet is
            being initialized. The lParam value is zero for this message.

            PSCB_PRECREATE      Indicates that the property sheet is about
            to be created. The hwndDlg parameter is NULL and the lParam
            parameter is a pointer to a dialog template in memory. This
            template is in the form of a DLGTEMPLATE structure followed
            by one or more DLGITEMTEMPLATE structures.

    lParam - Specifies additional information about the message. The
            meaning of this value depends on the uMsg parameter.

Return Value:

    The function returns zero.
