建立1个CONSOLE应用程序的时候(使用MFC支持):

using namespace std;

{
 

//下面是类的对象的代码,从CObject派生出来类有4种能力
/*

  • Serialization support

  • Run-time class information

  • Object diagnostic output

  • Compatibility with collection classes

*/

 //向导自动添加部分
 int nRetCode = 0;

 // initialize MFC and print and error on failure
 if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))    //看上面该函数定义
 {/*返回 HMODULE   ::GetModuleHandle(NULL)*/(HMODULE == HINSTANCE)
/*上面函数的参数[in]为NULL时,函数::GetModuleHandle(NULL)返回HINSTANCE基地址*/

 }
 else

  // TODO: code your application's behavior here.
  CString strHello;
  strHello.LoadString(IDS_HELLO);    //加载*.rc文件中定义的字符串
  cout << (LPCTSTR)strHello << endl;
 }

 return nRetCode;
}

在*.rc文件中:

// String Table
//

STRINGTABLE DISCARDABLE
BEGIN
    IDS_HELLO               "Hello from MFC!"
END

#endif
