I'm trying to add a close all command to my text editor. I have tried putting the below code in the WndProc and MDIProc but nothing happens. Where does it go?
Code:const char g_szChildClassName[] = "myMDIChildWindowClass"; case CM_CLOSEALL: { HWND hwnd = FindWindow(g_szChildClassName,NULL); SendMessage(hwnd, WM_CLOSE, 0,0); }
