4: *
5: * PURPOSE: To test the resource-only DLL "THE_DLL.DLL".
6: *
7: * FUNCTIONS: WinMain() - initialization, create window, msg loop
8: * MainWndProc() - processes main window msgs
9: * DrawBitmap() - draw a specified bitmap in a specified DC
10: *
11: * COMMENTS: Loads the bitmap, the cursor, and the icon from
12: * THE_DLL.DLL. Uses the first two ni registering the
13: * app's window class. Uses the bitmap when painting
14: * the client area.
