2: * sem_user.c - routines for handling messages not processed *
3: * by the standard message processing routine *
4: * Created 1990, Microsoft, IBM Corp. *
5: *--------------------------------------------------------------*
6: * *
7: * This module contains the code for processing messages sent *
8: * to the standard window that the standard window does not *
9: * process. The application developer need only modify this *
10: * file in order to implement new menu items or process *
11: * messages not handled by the standard message routine. *
12: * *
13: * This module also contains some routines that demonstate the *
14: * various dialog box controls and message box types that can *
15: * be used. The sample code should be deleted when this *
16: * module is modified for an application. The demonstration *
17: * code is identified by comments. *
18: * *
19: *--------------------------------------------------------------*
20: * *
21: * This source file contains the following functions: *
22: * *
23: * UserWndProc(hwnd, msg, mp1, mp2) - user window procedure*
24: * UserCommand(mp1, mp2) - user WM_COMMAND processor *
25: * SetForegroundColor(hwnd) *
26: * SetBackgroundColor(hwnd, nMenuId) *
27: * SetWindowText(hwnd) *
