msdn自带的一个利用CString的Tokenize函数进行分词的例子

// typedef CStringT<TCHAR, StrTraitATL<TCHAR, ChTraitsCRT<TCHAR>>> CAtlString;
CAtlString str(_T("%First Second#Third"));
CAtlString resToken;
int curPos = 0;

resToken= str.Tokenize(_T("% #"),curPos);
while (resToken != _T(""))
{
_tprintf_s(_T("Resulting token: %s\n"), resToken);
resToken = str.Tokenize(_T("% #"), curPos);
};

Remarks
The output from this example is as follows:

Resulting Token: First

Resulting Token: Second

Resulting Token: Third
