CFileFind类学习总结

这两天，我学习了一下CFileFind类，关于其使用，如下：

CFileFind

 Constructs a CFileFind object.

 

Attributes

GetCreationTime

 Gets the time the file was created.

GetFileName

 Gets the name, including the extension, of the found file

GetFilePath

 Gets the whole path of the found file.

GetFileTitle

 Gets the title of the found file. The title does not include the extension.

GetFileURL

 Gets the URL, including the file path, of the found file.

GetLastAccessTime

 Gets the time that the file was last accessed.

GetLastWriteTime

 Gets the time the file was last changed and saved.

GetLength

 Gets the length of the found file, in bytes.

GetRoot

 Gets the root directory of the found file.

IsArchived

 Determines if the found file is archived.

IsCompressed

 Determines if the found file is compressed.

IsDirectory

 Determines if the found file is a directory.

IsDots

 Determines if the name of the found file has the name "." or "..", indicating that is actually a directory.

IsHidden

 Determines if the found file is hidden.

IsNormal

 Determines if the found file is normal (in other words, has no other attributes).

IsReadOnly

 Determines if the found file is read-only.

IsSystem

 Determines if the found file is a system file.

IsTemporary

 Determines if the found file is temporary.

MatchesMask

 Indicates the desired file attributes of the file to be found.

 

Operations

Close

 Closes the search request.

CloseContext

 Closes the file specified by the current search handle.

FindFile

 Searches a directory for a specified file name.

FindNextFile

 Continues a file search from a previous call to FindFile.

为了巩固学习，特编写了两个小的程序，第一个主要实现了通过知道的盘符，遍历该盘符下所有目录，并以视图的形式通过CTreeCtrl控件表现出来，详细代码如下：

void CCFileFind_Tree_DemoDlg::OnBnClickedButton1()

{

     // TODO: 在此添加控件通知处理程序代码

     CString FileName1,FileName2;

     m_EdtFile.GetWindowTextW((CString &)FileName1);

     if(FileName1!=csTempText)

     {

         csTempText=FileName1;

         m_Tree.DeleteAllItems();

         if(true==m_RaDisk.GetCheck())

         {

              nStyle=0;

              FileName2.Format(L"%s://*.*",FileName1);

         }

         else

         {

              nStyle=1;

              FileName2.Format(L"%s//*.*",FileName1);

              MessageBox(L"无法查找遍历文件夹");

         }

         m_Root=m_Tree.InsertItem(FileName1,nStyle,nStyle);

         FileTraverse(FileName2,m_Root);

     }

     else

         MessageBox(L"只能输入一个遍历对象！");

}

void CCFileFind_Tree_DemoDlg::OnBnClickedRadio1()

{

     // TODO: 在此添加控件通知处理程序代码

     m_RaDisk.SetCheck(true);

}

void CCFileFind_Tree_DemoDlg::OnBnClickedRadio2()

{

     // TODO: 在此添加控件通知处理程序代码

     m_RaDisk.SetCheck(false);

}

bool CCFileFind_Tree_DemoDlg::FileTraverse(CString FileName,HTREEITEM m_ParItem)

{

     CFileFind finder;

     bool IsFinded=finder.FindFile(FileName);

     while(IsFinded)

     {

         IsFinded=(BOOL)finder.FindNextFileW();

         if(!IsFinded)

              continue;

         if(finder.IsDots())

              continue;

         if(finder.IsDirectory())

         {

              CString FileName3,FileName4;

              FileName3=finder.GetFilePath();

              FileName4=finder.GetFileName();

              //添加分支结点

              nStyle=1;

              m_CurItem=m_Tree.InsertItem(FileName4,nStyle,nStyle,m_ParItem);

              FileName3+="//*.*";

              bool iReturn=FileTraverse(FileName3,m_CurItem);

              if(true==iReturn)

              {

                   finder.Close();

              }

         }

         else

         {

              CString FileName3,FileName4;

              FileName3=finder.GetFilePath();

              FileName4=finder.GetFileName();

              //添加叶子结点

              nStyle=2;

              m_CurItem=m_Tree.InsertItem(FileName4,nStyle,nStyle,m_ParItem);

         }

     }

     finder.Close();

     return false;

}

程序运行图如下：

第二个程序主要是通过盘符和文件名，查找制定文件，并将文件路径显示出来，详细代码如下：

void CCFileFindTestDlg::OnBnClickedSearch()

{

     // TODO: 在此添加控件通知处理程序代码

     CString csDisk,csFileName,csDirName;

     m_EdtDisk.GetWindowText((CString &)csDisk);

     m_EdtFileName.GetWindowText((CString &)csFileName);

     csDirName.Format(L"%s://*.*",csDisk,csFileName);

     SearchFile(csDirName,csFileName);

     m_EdtPath.SetWindowText(csReturn);

}

bool  SearchFile(CString csDirName,CString csFileName)

{

     CFileFind finder;

     bool IsFinded=finder.FindFile(csDirName);

     while(IsFinded)

     {

         IsFinded=(BOOL)finder.FindNextFile();

         if(!IsFinded)

         {

              continue;

         }

         if(finder.IsDots())

              continue;

         if(finder.IsDirectory())

         {

              CString csNewDirName;

              csNewDirName=finder.GetFilePath();

              csNewDirName+=L"//*.*";

              int iReturn=SearchFile(csNewDirName,csFileName);

              if(iReturn==true)

              {

                   finder.Close();

                   return true;

              }

         }

         else

         {

              CString csCurName;

              csCurName=finder.GetFileName();

//            MessageBox(NULL,csCurName,NULL,0);

              if(/*finder.GetFileName()*/csCurName==csFileName)

              {

                   CString csNewDirName;

                   csNewDirName=finder.GetFilePath();

                   csReturn=csNewDirName;

                   finder.Close();

                   return true;

              }

         }

     }

     finder.Close();

    return false;

}
