 * This procedure processes the keys sent to a dialog that implements the page of a     *
 * notebook control. Navigation keys are processed within the dialog page, all other    *
 * keys are forwarded to the frame window whose client area the notebook control is     *
 * part of.                                                                             *
 * Req:                                                                                 *
 *      hwndPage ...... Dialog implementing notebook page                               *
 *      hwndDialog .... Dialog where the notebook control is part of the client         *
 *      mp1 ........... Parameter 1 of WM_CHAR message sent to notebook page            *
 *      mp1 ........... Parameter 2 of WM_CHAR message sent to notebook page            *
 * Ret:                                                                                 *
 *      ulRc .......... Return code: TRUE no error, FALSE otherwise                     *
