MFC下调试日志的打印

最近项目出现点小Bug，需要调试跟踪代码，于是乎写了份打印日志的代码。

CLogFile.h文件

 #if !defined(AFX_LOGFILE_H__288388CA_9A3E_4F3D_A2B8_F1078E1F6A6B__INCLUDED_)
 #define AFX_LOGFILE_H__288388CA_9A3E_4F3D_A2B8_F1078E1F6A6B__INCLUDED_

 #if _MSC_VER > 1000
 #pragma once
 #endif // _MSC_VER > 1000

 class CLogFile
 {
 public:
     CLogFile();
     ~CLogFile();
 private:
     static CString GetFileName();
     static CString GetFilePath();
 public:
     static bool WriteLog(CString LogText);
 };

 #endif // !defined(AFX_LOGFILE_H__288388CA_9A3E_4F3D_A2B8_F1078E1F6A6B__INCLUDED_)

CLogFile.cpp文件

 #include "stdafx.h"
 #include "CLogFile.h"

 CLogFile::CLogFile()
 {

 }

 CLogFile::~CLogFile()
 {

 }
 //获取文件名称
 CString CLogFile::GetFileName()
 {
     CString sFileName;

     sFileName = CTime::GetCurrentTime().Format("%Y-%m-%d") + TEXT(".log"); 

     return sFileName;
 } 

 //获取应用程序所在路径
 CString CLogFile::GetFilePath()
 {
     CString m_FilePath;

     GetModuleFileName(NULL,m_FilePath.GetBufferSetLength(MAX_PATH+),MAX_PATH);

     m_FilePath.ReleaseBuffer();

     int m_iPosIndex;

     m_iPosIndex = m_FilePath.ReverseFind('\\'); 

     //m_FilePath = m_FilePath.Left(m_iPosIndex) + TEXT("\\Log");
     m_FilePath = "D:\\VISTA\\LOGSA";

     return m_FilePath;
 }

 bool CLogFile::WriteLog(CString LogText)
 {
     try
     {
         //CFile m_File;
         CFile m_SFile;
         CFileFind m_FileFind;
         CString m_sErrorMessage;
         CString m_sFileName = GetFileName();
         CString m_sFilePath = GetFilePath();
         CString m_sCurrentTime = CTime::GetCurrentTime().Format("%Y-%m-%d %X"); 

         if(!m_FileFind.FindFile(m_sFilePath))
         {
             CreateDirectory(m_sFilePath,NULL);
         } 

         m_SFile.Open(m_sFilePath + TEXT("\\") +m_sFileName,CFile::modeCreate |CFile::modeNoTruncate| CFile::modeReadWrite |CFile::shareDenyWrite);
         /*{
         m_SFile.Open(m_sFilePath + TEXT("\\") + m_sFileName,CFile::modeCreate | CFile::modeReadWrite |CFile::shareDenyWrite| CFile::typeText);
     }*/ 

         m_SFile.SeekToEnd(); 

         if(sizeof(TCHAR)==sizeof(WCHAR))
         {
             WORD wSignature = 0xFEFF;
             m_SFile.Write(&wSignature, );
         }        

         //TCHAR* m_szMessage;

         //m_szMessage=m_sErrorMessage.GetBuffer();

         m_sErrorMessage = TEXT("*******************") + m_sCurrentTime + TEXT("*******************")+TEXT("\r\n") ;
         m_SFile.Write(m_sErrorMessage,m_sErrorMessage.GetLength()*sizeof(TCHAR));

         //m_sErrorMessage = LogText ;
         LogText+=TEXT("\r\n");
         m_SFile.Write(LogText,LogText.GetLength()*sizeof(TCHAR));
         //m_sErrorMessage = TEXT("*******************") + m_sCurrentTime + TEXT("*******************") ;
         m_SFile.Write(m_sErrorMessage,m_sErrorMessage.GetLength()*sizeof(TCHAR));

         //m_SFile.Write(m_sErrorMessage.GetBuffer(),m_sErrorMessage.GetLength());   

         m_SFile.Close();
     }
     catch(CFileException fileException)
     {
         return false;
     }

     return true;
 }

以上代码经过调试通过！
