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+1),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;

        CString m_sErrorMessage; 
        CString m_sFileName = GetFileName(); 
        CString m_sFilePath = GetFilePath(); 
        CString m_sCurrentTime = CTime::GetCurrentTime().Format("%Y-%m-%d %X");

        { 
            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, 2); 
        }        
        
        //TCHAR* m_szMessage;
        
        //m_szMessage=m_sErrorMessage.GetBuffer();
        
        m_sErrorMessage = TEXT("*******************") + m_sCurrentTime + TEXT("*******************")+TEXT("

        m_SFile.Write(m_sErrorMessage,m_sErrorMessage.GetLength()*sizeof(TCHAR));
        
        //m_sErrorMessage = LogText ; 
        LogText+=TEXT("
"); 
        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！
