MFC's initialization process and message mapping technology

1. Delete # include in <windows.h>--win32-(MFC must be removed using Win32 engineering programming)

Add # include <afxwin.h>--in MFC-

2. Start by CWinApp

CWINAPP theapp;//globally defines the object of this class, starting with it as the spindle

The InitInstance () function is treated as WinMain (Win32), and the main function

3.Debug Version : Something corresponding to the debug message

Release version : Without some debug information: compiled out much smaller--release version

--VC does not display the selection release, the upper right-click blank inside the selection
