* sem_user.c - routines for handling messages not processed *
* by the standard message processing routine *
* Created 1990, Microsoft, IBM Corp. *
*--------------------------------------------------------------*
* *
* This module contains the code for processing messages sent *
* to the standard window that the standard window does not *
* process. The application developer need only modify this *
* file in order to implement new menu items or process *
* messages not handled by the standard message routine. *
* *
* This module also contains some routines that demonstate the *
* various dialog box controls and message box types that can *
* be used. The sample code should be deleted when this *
* module is modified for an application. The demonstration *
* code is identified by comments. *
* *
*--------------------------------------------------------------*
* *
* This source file contains the following functions: *
* *
* UserWndProc(hwnd, msg, mp1, mp2) - user window procedure*
* UserCommand(mp1, mp2) - user WM_COMMAND processor *
* SetForegroundColor(hwnd) *
* SetBackgroundColor(hwnd, nMenuId) *
* SetWindowText(hwnd) *
