文件读写方法小记2

①遍历文件夹并且计算文件夹个数

    int iCount = 0;    CString strTempPath;    CString strFileName;    strTempPath = CBApp::getCurrModulePath() + _T("ini");    BOOL bWorking = finder.FindFile(strTempPath + _T("\\*.*"));     while (bWorking)     {         bWorking = finder.FindNextFile();        if(!finder.IsDots())        {            iCount++;        }            strFileName = finder.GetFilePath();    }

②删除非空的文件夹

bool CBSetting::DeleteDirectory(CString sPath)  {      CFileFind Finder;     CString sDir;    sDir.Format(_T("%s\\*.*"),sPath);    BOOL IsFinded = Finder.FindFile(sDir);      while (IsFinded)      {          IsFinded = Finder.FindNextFile();        if (!Finder.IsDots())          {              if (Finder.IsDirectory())                  DeleteDirectory(Finder.GetFilePath());               else                  DeleteFile(Finder.GetFilePath());          }      }      Finder.Close();      if(!RemoveDirectory(sPath))      {          return FALSE;      }      return TRUE;  } 

③文件的删除和重命名

//删除预设文件void CBSetting::deleteSettingFile(CString &sBoyeApp, CBObList &settingList, int iIndex){    CFileFind Finder;     CString sName;    sName.Format(_T("\\%d.ini"), iIndex);    CString strPath = sBoyeApp + sName;    if(Finder.FindFile(strPath))    {        DeleteFile(strPath);    }    else        return;    CString sOldName, sOldPath;    for (POSITION pos = settingList.FindIndex(iIndex); pos != NULL; iIndex ++)    {        settingList.GetNext(pos);        sOldName.Format(_T("\\%d.ini"), iIndex + 1);        sOldPath = sBoyeApp + sOldName;        if(Finder.FindFile(sOldPath))             CFile::Rename(sOldPath, strPath); //重命名文件        strPath = sOldPath;    }}

④文件夹的删除和重命名

//删除对应的设备保存文件void CBSetting::deleteDeviceFile(int iIndex){    CString sPath;    CString sOldPath;    CFileFind Finder;     sPath.Format(_T("ini\\%d"), iIndex);    sPath = CBApp::getCurrModulePath() + sPath;    if(Finder.FindFile(sPath))    {        DeleteFolder(sPath);    }    else        return;        for (POSITION pos = m_DeviceList.FindIndex(iIndex); pos != NULL; iIndex ++)    {                m_DeviceList.GetNext(pos);        sOldPath.Format(_T("ini\\%d"), iIndex + 1);        sOldPath = CBApp::getCurrModulePath() + sOldPath;        if(Finder.FindFile(sOldPath))            ReNameFolder(sOldPath, sPath);            sPath = sOldPath;    }    Finder.Close();}//删除文件夹void CBSetting::DeleteFolder(CString sOldPath) {     int nLength = sOldPath.GetLength();    TCHAR *pNewPath = new TCHAR[nLength+2];    memcpy(pNewPath, sOldPath.GetBuffer(), nLength * sizeof(TCHAR));    pNewPath[nLength] = '\0';    pNewPath[nLength+1] = '\0';    SHFILEOPSTRUCT FileOp;     ZeroMemory((void*)&FileOp,sizeof(SHFILEOPSTRUCT));    FileOp.fFlags = FOF_NOCONFIRMATION;     FileOp.hNameMappings = NULL;     FileOp.hwnd = NULL;     FileOp.lpszProgressTitle = NULL;     FileOp.pFrom = pNewPath;     FileOp.pTo = NULL;     FileOp.wFunc = FO_DELETE;       SHFileOperation(&FileOp);    delete pNewPath;}//重命名文件夹void CBSetting::ReNameFolder(CString sOldName,CString sNewName){    int nLength = sOldName.GetLength();    TCHAR *pOldPathName = new TCHAR[nLength + 2];    memcpy(pOldPathName, sOldName.GetBuffer(), nLength * sizeof(TCHAR));    pOldPathName[nLength] = '\0';    pOldPathName[nLength + 1] = '\0';    SHFILEOPSTRUCT FileOp;     ZeroMemory((void*)&FileOp,sizeof(SHFILEOPSTRUCT));    FileOp.fFlags = FOF_NOCONFIRMATION ;     FileOp.hNameMappings = NULL;     FileOp.hwnd = NULL;     FileOp.lpszProgressTitle = NULL;     FileOp.pFrom = pOldPathName;     FileOp.pTo = sNewName;     FileOp.wFunc = FO_RENAME;         SHFileOperation(&FileOp);    delete pOldPathName;}
