MFC下对文件及文件夹的操作(复制、剪切、删除、创建文件夹，写文件)
一、文件夹的创建
1 void CFileOperationDlg::OnButtonMakeFolder() 2 { 3 // TODO: Add your control notification handler code here 4 UpdateData(TRUE); 5 CFileFind m_sFileFind; 6 7 if (!m_sFileFind.FindFile(m_FolderName)) 8 { 9 CreateDirectory(m_FolderName,NULL); 10 } 11 }
二、文件的创建
1 void CFileOperationDlg::OnButtonMakeFile() 2 { 3 // TODO: Add your control notification handler code here 4 UpdateData(TRUE); 5 CFile m_sFile; 6 m_sFile.Open(m_FolderName + TEXT("\\") + m_FileName,CFile::modeCreate|CFile::modeNoTruncate|CFile::modeReadWrite|CFile::shareDenyWrite); 7 m_sFile.SeekToEnd(); 8 m_sFile.Close(); 9 }
三、文件夹的复制(包括文件的复制)
1 void CFileOperationDlg::OnButtonCopy() 2 { 3 // TODO: Add your control notification handler code here 4 UpdateData(TRUE); 5 CString m_strDestPath; 6 m_strDestPath = "D:\\TestMyself\\FileOperation\\Debug"; 7 CString m_strSrcPath = "D:\\TestMyself\\FileOperation\\VISTA"; 8 CopyDirectory(m_strSrcPath,m_strDestPath); 9 } 10 11 BOOL CFileOperationDlg::CopyDirectory(CString strSrcPath,CString strDestPath) 12 { 13 CFileFind m_sFileFind; 14 if (strSrcPath.IsEmpty()) 15 { 16 OutputDebugString("源文件名为空，无法进行拷贝!"); 17 return FALSE; 18 } 19 if (!m_sFileFind.FindFile(strDestPath)) 20 { 21 CreateDirectory(strDestPath,NULL);//创建目标文件夹 22 } 23 CFileFind finder; 24 CString path; 25 path.Format("%s/*.*",strSrcPath); 26 //AfxMessageBox(path); 27 BOOL bWorking = finder.FindFile(path); 28 while (bWorking) 29 { 30 bWorking = finder.FindNextFile(); 31 //AfxMessageBox(finder.GetFileName()); 32 if (finder.IsDirectory() && !finder.IsDots())//是文件夹 而且 名称不含 . 或 .. 33 { 34 CopyDirectory(finder.GetFilePath(),strDestPath+"/"+finder.GetFileName());//递归创建文件夹+"/"+finder.GetFileName() 35 } 36 else 37 {//是文件，则直接复制 38 //AfxMessageBox("复制文件"+finder.GetFilePath());//+finder.GetFileName() 39 CopyFile(finder.GetFilePath(),strDestPath+"/"+finder.GetFileName(),FALSE); 40 } 41 } 42 43 return TRUE; 44 } 45 46 CString CFileOperationDlg::GetFilePath() 47 { 48 CString m_FilePath; 49 50 GetModuleFileName(NULL,m_FilePath.GetBufferSetLength(MAX_PATH+1),MAX_PATH); 51 m_FilePath.ReleaseBuffer(); 52 53 int m_iPosIndex; 54 m_iPosIndex = m_FilePath.ReverseFind('\\'); 55 m_FilePath = m_FilePath.Left(m_iPosIndex+1); 56 57 return m_FilePath; 58 } 59 60 CString CFileOperationDlg::GetFileName() 61 { 62 CString sFileName; 63 64 sFileName = CTime::GetCurrentTime().Format("%Y-%m-%d") + TEXT(".log"); 65 66 return sFileName; 67 }
四、文件夹的删除
1 BOOL CFileOperationDlg::DeleteFolder(LPCTSTR lpszPath) 2 { 3 int nLength = strlen(lpszPath); 4 char *NewPath = new char[nLength + 2]; 5 strcpy(NewPath,lpszPath); 6 NewPath[nLength] = '\0'; 7 NewPath[nLength + 1] = '\0'; 8 SHFILEOPSTRUCT FileOp; 9 ZeroMemory((void*)&FileOp,sizeof(SHFILEOPSTRUCT)); 10 FileOp.fFlags = FOF_NOCONFIRMATION; 11 FileOp.hNameMappings = NULL; 12 FileOp.hwnd = NULL; 13 FileOp.lpszProgressTitle = NULL; 14 FileOp.pFrom = NewPath; 15 FileOp.pTo = NULL; 16 FileOp.wFunc = FO_DELETE; 17 return SHFileOperation(&FileOp) == 0; 18 }
五、文件夹的移动（剪切）
1 BOOL CFileOperationDlg::MoveFolder(LPCTSTR lpszFromPath,LPCTSTR lpszToPath) 2 { 3 int nLengthFrm = strlen(lpszFromPath); 4 char *NewPathFrm = new char[nLengthFrm + 2]; 5 strcpy(NewPathFrm,lpszFromPath); 6 NewPathFrm[nLengthFrm] = '\0'; 7 NewPathFrm[nLengthFrm + 1] = '\0'; 8 SHFILEOPSTRUCT FileOp; 9 ZeroMemory((void*)&FileOp,sizeof(SHFILEOPSTRUCT)); 10 FileOp.fFlags = FOF_NOCONFIRMATION ; 11 FileOp.hNameMappings = NULL; 12 FileOp.hwnd = NULL; 13 FileOp.lpszProgressTitle = NULL; 14 FileOp.pFrom = NewPathFrm; 15 FileOp.pTo = lpszToPath; 16 FileOp.wFunc = FO_MOVE; 17 18 return SHFileOperation(&FileOp) == 0; 19 }
六、文件写操作
1 void CFileOperationDlg::OnButtonOk() 2 { 3 // TODO: Add your control notification handler code here 4 UpdateData(TRUE); 5 try 6 { 7 CFile m_sFile; 8 CFileFind m_FileFind; 9 CString m_sErrorMessage; 10 //CString m_sFileName = GetFileName(); 11 //CString m_sFilePath = GetFilePath(); 12 CString m_sCurrentTime = (CTime::GetCurrentTime()).Format("%Y-%m-%d %X"); 13 14 if (!m_FileFind.FindFile(m_FolderName)) 15 { 16 CreateDirectory(m_FolderName,NULL); 17 } 18 m_sFile.Open(m_FolderName + TEXT("\\") +m_FileName,CFile::modeCreate |CFile::modeNoTruncate| CFile::modeReadWrite |CFile::shareDenyWrite); 19 20 m_sFile.SeekToEnd(); 21 22 if (sizeof(TCHAR) == sizeof(WCHAR)) 23 { 24 WORD wSignature = 0xFFFF; 25 m_sFile.Write(&wSignature,2); 26 } 27 28 m_sErrorMessage = TEXT("*******************") + m_sCurrentTime + TEXT("*******************")+TEXT("\r\n") ; 29 m_sFile.Write(m_sErrorMessage,m_sErrorMessage.GetLength()*sizeof(TCHAR)); 30 31 m_RichText += TEXT("\r\n");\ 32 m_sFile.Write(m_RichText,m_RichText.GetLength()*sizeof(TCHAR)); 33 m_sFile.Close(); 34 } 35 catch(CFileException fileException) 36 { 37 return ; 38 } 39 40 }
以上代码测试通过！！
