1. ifstream myFile ;
CStdString strForbiddenFilePathName = strModulePathName + "forbbiden.dat" ;
myFile.open(strForbiddenFilePathName.c_str()) ;

2. // 注：下面的代码中CStdString不是C++的内置类型，如果要复制，请相应更改成string等。有些函数是本人自己写的，也要相应删除。
ifstream myFile1 ;
string strTemp1 ;
CStdString strUrl = strModulePathName + "url.txt" ;
myFile1.open(strUrl.c_str()) ;
ofstream myFileOut1;
CStdString strExtractContent = strModulePathName + "ExtractContent.txt" ;
myFileOut1.open(strExtractContent.c_str()) ;
strTemp1.clear() ;
while (getline(myFile1, strTemp1))
{
TestAnalyze.GetArtical(strTemp1, strMyTitle, strMyContent) ;
myFileOut1<<strTemp1.c_str()<<endl<<strMyTitle.c_str()<<"##"<<endl<<strMyContent.c_str()<<endl<<"####"<<endl ;
strTemp1.clear() ;
strMyTitle.clear() ;
strMyContent.clear() ;
}
myFile1.close() ;
myFile1.clear() ;
myFileOut1.close() ;
myFileOut1.clear() ;
另一个例子：
ofstream a ;
a.open ("1.txt") ;
DWORD I = GetTickCount () ;
for (int i =0; i<10000; ++i)
a<< 2011 << "-" << 8 << "-" << 3 << " " << 14 << ":" << 22 << ":" << 59
<< "\t" << "172.17.17.11" << "\t" << "49801bcf518c445 " << "\t" << "logvertest.exe"
<< "\t" << "Administrator" << "\t" << "无" << "\t" << "Run"
<< "\t" << "neirong" << "\t" << "Warn" << "\r\n";
DWORD II = GetTickCount () - I ;
注意：直接写数字的花费的时间比写字符的快。如 写8 比 写"08"快。
