如何在VC中创建LOG文件???????

Question

Answer 1

定义一个FILE*全局变量，一开始运行的时候打开一个文本文件，程序推出前关闭，读写数据的时候，用fprintf写log，定期flush

参考：
BOOL CLogFile::WriteLogFile(CString sFilePath)//sFilePath :  c:\work\file.log
{
BOOL bRtn = TRUE;
CStdioFile fLogFile;
CFileFind fFind;
if ( !fFind.FindFile(sFilePath, 0) )
{
//create log file
if ( !fLogFile.Open(sFilePath, CFile::modeCreate | CFile::modeWrite) )
{
//error
CErrMsg errMsg;
errMsg.GetWarningErr(LOG_FILE_WRITE_ERR, sFilePath);
bRtn = FALSE;
}
else
{
CString sHeadStr; sHeadStr = _T("操作時間,操作タイプ,操作ファイル,前後版数,結果");
fLogFile.WriteString(sHeadStr);
fLogFile.WriteString(_T("\n")); CString sTmp; sTmp = this->m_ExeTime + _T(",");
sTmp += this->m_ExeType + _T(",");
sTmp += this->m_ExeFile + _T(",");
sTmp += this->m_VerChg + _T(",");
sTmp += this->m_Result + _T("\n"); fLogFile.WriteString(sTmp);
fLogFile.Close();
}
}
else
{
if ( !fLogFile.Open(sFilePath, CFile::modeWrite) )
{
//error
CErrMsg errMsg;
errMsg.GetWarningErr(LOG_FILE_WRITE_ERR, sFilePath);
bRtn = FALSE;
}
else
{
CString sTmp;
fLogFile.SeekToEnd(); sTmp = this->m_ExeTime + _T(",");
sTmp += this->m_ExeType + _T(",");
sTmp += this->m_ExeFile + _T(",");
sTmp += this->m_VerChg + _T(",");
sTmp += this->m_Result + _T("\n"); fLogFile.WriteString(sTmp);
fLogFile.Close();
}
}
return bRtn;
