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

 1 #if !defined(AFX_LOGFILE_H__288388CA_9A3E_4F3D_A2B8_F1078E1F6A6B__INCLUDED_) 
 2 #define AFX_LOGFILE_H__288388CA_9A3E_4F3D_A2B8_F1078E1F6A6B__INCLUDED_

 4 #if _MSC_VER > 1000 
 5 #pragma once 
 6 #endif // _MSC_VER > 1000
 7 
 8 class CLogFile  
 9 { 
10 public: 
11     CLogFile(); 
12     ~CLogFile(); 
13 private: 
14     static CString GetFileName(); 
15     static CString GetFilePath(); 
16 public: 
17     static bool WriteLog(CString LogText); 
18 };
19 
20 #endif // !defined(AFX_LOGFILE_H__288388CA_9A3E_4F3D_A2B8_F1078E1F6A6B__INCLUDED_)

CLogFile.cpp文件

 1 #include "stdafx.h" 
 2 #include "CLogFile.h"

64         
65         m_SFile.SeekToEnd(); 
66         
67         if(sizeof(TCHAR)==sizeof(WCHAR)) 
68         { 
69             WORD wSignature = 0xFEFF; 
70             m_SFile.Write(&wSignature, 2); 
71         }        
72

74         
75         //m_szMessage=m_sErrorMessage.GetBuffer();
76         
77         m_sErrorMessage = TEXT("*******************") + m_sCurrentTime + TEXT("*******************")+TEXT("\r\n") ; 
78         m_SFile.Write(m_sErrorMessage,m_sErrorMessage.GetLength()*sizeof(TCHAR));
79         
80         //m_sErrorMessage = LogText ; 
81         LogText+=TEXT("\r\n"); 
82         m_SFile.Write(LogText,LogText.GetLength()*sizeof(TCHAR)); 
83         //m_sErrorMessage = TEXT("*******************") + m_sCurrentTime + TEXT("*******************") ; 
84         m_SFile.Write(m_sErrorMessage,m_sErrorMessage.GetLength()*sizeof(TCHAR));
85         
86         //m_SFile.Write(m_sErrorMessage.GetBuffer(),m_sErrorMessage.GetLength());   
87         
88         m_SFile.Close(); 
89     } 
90     catch(CFileException fileException) 
91     { 
92         return false; 
93     }
94     
95     return true; 
96 }

以上代码经过调试通过！
