写日志(注意不要用CString)

因为CString不是安全的，当程序非正常结束时，有可能产生内存泄露

void WriteToLog(CString strInfo, CString fileName)
{
try
{

  char path[512];
  ::GetModuleFileName(NULL, path, 512);
  int len = strlen(path);
  for (int i=len; i>0; i--)
  {
   if ('//' == path[i])
   {
    path[i] = '/0';
    break;
   }
  }

  strcat(path, _T("//"));
  strcat(path, fileName);

  char   tmpStr[512];
  ZeroMemory(tmpStr, 512);
  CTime   mTime;
  mTime=CTime::GetCurrentTime();
  sprintf(tmpStr, _T("%04d-%02d-%02d %02d:%02d:%02d      %s/r/n"), mTime.GetYear(),
   mTime.GetMonth(),
   mTime.GetDay(),
   mTime.GetHour(),
   mTime.GetMinute(),
   mTime.GetSecond(),
   strInfo);



  int   nLen=strlen(tmpStr);
  TCHAR*   tBuf = tmpStr;

  CFile   file;

  if (file.Open(path,CFile::modeCreate |CFile::modeNoTruncate | CFile::modeWrite, NULL))
  {
   file.SeekToEnd();
   file.Write(tBuf,nLen*sizeof(TCHAR));
   file.Close();
  }
}
catch   (...)
{
  TRACE(_T("WriteToLog/n"));
}
}
