4、如果你想自己添加函数,可以用ClassWizard添加一个自动化类。

ClasWizard将为IDispatch接口产生如下头文件与执行文件:

// CScriptControlMacroDispatch class

5、这样在产生的代码中已经实现了一些自定义的东西

a. 不必要的声名和代码已经删除

b. 全局的应用程序对象已经声名:extern CScriptControlMacroApp theApp

c. MFC隐含函数声名已经添加:CString AFXAPI AfxStringFromCLSID( REFCLSID ).

d. 为了使用AfxStringFromCLSID,IID_IScriptControlMacroDispatch定义已经移到了头文件中

6、为了在所有MFC程序中方便地提供Unicode支持,在AFX.H头文件中作了如下定制: ////////////////////////////////////////////////////////////
// Win32 libraries
// Start of customization
#ifdef _UNICODE
  #pragma comment(linker, "/entry:wWinMainCRTStartup")
#endif
// End of customization
7、为了在所有MFC工程中使用 _WIN32_WINDOWS=0x500 这个预定义,在AFXV_W32.H头文件中作了如下定制: #ifndef ALL_WARNINGS
#pragma warning(disable: 4201)
  // winnt.h uses nameless structs
#endif
// Start of customization
#ifndef _WIN32_WINDOWS
// End of customization
#define _WIN32_WINDOWS 0x0500
// Start of customization
#endif
// End of customization
