VC++ MFC 文件处理unicode

 1.读取文件；

// TCHAR szFilters[]= _T("MyType Files (*.my)|*.my|All Files (*.*)|*.*||");
   //跳出对话框，选择指定的文件类型
   TCHAR szFilters[]= _T("DXF Files (*.dxf)|*.dxf");

   // Create an Open dialog; the default file name extension is ".my".
   CFileDialog fileDlg(TRUE, _T("dxf"), _T("*.dxf"),
      OFN_FILEMUSTEXIST | OFN_HIDEREADONLY, szFilters);

   // Display the file dialog. When user clicks OK, fileDlg.DoModal()  
   // returns IDOK. 
   if(fileDlg.DoModal() == IDOK)
   {
      CString pathName = fileDlg.GetPathName();

      // Implement opening and reading file in here. 

      //Change the window's title to the opened file's title.
      CString fileName = fileDlg.GetFileTitle();
      CString strLine;    
      CStdioFile myFile;
       
      myFile.Open(pathName,CFile::modeRead);
      //逐行读取
      while(myFile.ReadString(strLine))
      {
         if(strLine=="AcDbLine")
         {            
             do 
             {
                 
                 myFile.ReadString(strLine);
                 strLine.Trim();
                 if(strLine=="10")
                 {
                    myLinePoint.push_back(LinePoint());    
                    myFile.ReadString(strLine);            
                    myLinePoint[i].start_x=_tstof(strLine);
                 }
                 if(strLine=="31")
                 {
                     myFile.ReadString(strLine);
                    
                     myLinePoint[i].end_z=_tstof(strLine);
                     i++;
                 }
                 
             } while (strLine!="0");

         }
      }

2.跳出对话框选择文件目录，list勾选所选择的项目，读取文本文档，写入文本档，进度条；

void CFurtherConvertCutCodeView::OnBnClickedButtonBrowser()
{
	CString filePath;
	m_ProgressFile.SetPos(0);
	m_ListFiles.ResetContent();
	TCHAR szPath[_MAX_PATH];
	BROWSEINFO bi;
	bi.hwndOwner=NULL;
	bi.pidlRoot=NULL;
	bi.lpszTitle=_T("文件浏览");
	bi.pszDisplayName=szPath;
	bi.ulFlags=BIF_RETURNONLYFSDIRS;
	bi.lParam=NULL;
	bi.lpfn=NULL;
	LPITEMIDLIST pItemIDList=SHBrowseForFolder(&bi);
	if(pItemIDList)
	{
		if(SHGetPathFromIDList(pItemIDList,szPath))
		filePath=szPath;
		CFileFind finder;
		CString strFilenName;
		BOOL bWorking=finder.FindFile(filePath+"\\*.din");
		while(bWorking)
		{
			bWorking = finder.FindNextFile();
			strFilenName=(LPCTSTR)finder.GetFileName();  //str为取得一个文件名
			m_ListFiles.AddString(strFilenName);
		}
		
	}
	else
	{
       filePath="";
	}

	GetDlgItem(IDC_STATIC_Browse)->SetWindowText(filePath);
	

}


void CFurtherConvertCutCodeView::OnBnClickedButtonRun()
{
	// TODO: Add your control notification handler code here
	CString strFilePath;
	//添加光顺后程序保存的目录
	CString strPath;
	GetDlgItem(IDC_STATIC_Browse)->GetWindowText(strFilePath);
	CString strFileName;
	//找出勾选的项目
	int iSel=m_ListFiles.GetCount();
	if(iSel>0)
	{
		   strPath=strFilePath+_T("\\_GCG261");
		   CreateDirectory(strPath,NULL);
	}
	m_ProgressFile.SetPos(0);
	int j=0;
	for(int i=0;i<iSel;i++)
	{
		int ik=m_ListFiles.GetCheck(i);
		if(m_ListFiles.GetCheck(i)==1)
		{
			j++;			
		}		

	}
	m_ProgressFile.SetRange(0,j);
	m_ProgressFile.SetStep(1);
	for(int i=0;i<iSel;i++)
	{
		int ik=m_ListFiles.GetCheck(i);
		if(m_ListFiles.GetCheck(i)==1)
		{
			m_ListFiles.GetText(i,strFileName);
			ReadCodeFile(strFilePath+"\\"+strFileName,strPath+"\\"+strFileName);
			m_ProgressFile.StepIt();		   
		}		
		
	}
}
void CFurtherConvertCutCodeView::ReadCodeFile(CString strFileName,CString strWriteFileName)
{
	CStringList listLines;	
	CString strLine;	
	CString strPartLine;
	CStdioFile writeFile;
	bool isG01=false;

	myFile.Open(strFileName,CFile::modeRead);
	
	CFile mFile;

	//逐行读取
	while(myFile.ReadString(strLine))
	{
	   CArchive ar(&mFile,CArchive::store);

			 }//end while
		   isBreak=false;
		   if(isAddG261==true)
		   {
			   strLine="G261\r\nM07";		      
		   }
