MFC选择文件和文件夹对话框

vs2013环境要求比vc6.0严格些。以前的代码不能直接拿来用，做了些修改。有效果图。

打开文件：

\[cpp\] [view plain][] [copy][view plain]

1.  CString gReadFilePathName; 
2.  CFileDialog fileDlg(**true**, \_T("mp3"), \_T("\*.mp3"), OFN\_HIDEREADONLY | OFN\_OVERWRITEPROMPT, \_T("mp3 Files (\*.mp3)|\*.mp3|wav File(\*.wav)|\*.wav|All File (\*.\*)|\*.\*||"), NULL); 
3.  **if** (fileDlg.DoModal() == IDOK) //弹出对话框
4.  \{ 
5.   gReadFilePathName = fileDlg.GetPathName();//得到完整的文件名和目录名拓展名
6.   GetDlgItem(IDC\_EDIT1)->SetWindowText(gReadFilePathName);//将路径显示
7.   CString filename = fileDlg.GetFileName(); 
8.  \}

打开文件夹：

\[cpp\] [view plain][] [copy][view plain]

1.  CFileFind finder; 
2.  CString path; 
3.  **BOOL** fileExist; 
4.  
5.  // 获取特定文件夹的LPITEMIDLIST，可以将之理解为HANDLE
6.  // 所谓的特定文件夹,你可以用CSIDL\_XXX来检索之。
7.  LPITEMIDLIST rootLoation; 
8.  SHGetSpecialFolderLocation(NULL, CSIDL\_DESKTOP, &rootLoation); 
9.  **if** (rootLoation == NULL) \{ 
10. // unkown error
11. **return**; 
12. \} 
13. // 配置对话框
14. BROWSEINFO bi; 
15. ZeroMemory(&bi, **sizeof**(bi)); 
16. bi.pidlRoot = rootLoation; // 文件夹对话框之根目录，不指定的话则为我的电脑
17. bi.lpszTitle = \_T("对话框抬头"); // 可以不指定
18. // bi.ulFlags = BIF\_EDITBOX | BIF\_RETURNONLYFSDIRS;
19. 
20. // 打开对话框, 有点像DoModal
21. LPITEMIDLIST targetLocation = SHBrowseForFolder(&bi); 
22. **if** (targetLocation != NULL) \{ 
23. **TCHAR** targetPath\[MAX\_PATH\]; 
24.  SHGetPathFromIDList(targetLocation, targetPath); 
25. //MessageBox( targetPath );
26.  GetDlgItem(IDC\_EDIT1)->SetWindowText(targetPath);//将路径显示
27. \} 
28.

在MFC编程中经常会需要用到选择目录和选择文件的界面，以下总结一下本人常用的这两种对话框的生成方法：  
  
选择目录对话框

![None.gif][] // 选择目录按钮   
![None.gif][] void  CDcPackerDlg::OnBnClickedDecgen()  
![ExpandedBlockStart.gif][] \{  
![InBlock.gif][]char szPath\[MAX\_PATH\]; //存放选择的目录路径   
![InBlock.gif][] CString str;  
![InBlock.gif][]  
![InBlock.gif][] ZeroMemory(szPath, sizeof(szPath));  
![InBlock.gif][]  
![InBlock.gif][] BROWSEINFO bi;  
![InBlock.gif][] bi.hwndOwner = m\_hWnd;  
![InBlock.gif][] bi.pidlRoot = NULL;  
![InBlock.gif][] bi.pszDisplayName = szPath;  
![InBlock.gif][] bi.lpszTitle ="请选择需要打包的目录：";  
![InBlock.gif][] bi.ulFlags =0;  
![InBlock.gif][] bi.lpfn = NULL;  
![InBlock.gif][] bi.lParam =0;  
![InBlock.gif][] bi.iImage =0;  
![InBlock.gif][]//弹出选择目录对话框  
![InBlock.gif][] LPITEMIDLIST lp = SHBrowseForFolder(&bi);  
![InBlock.gif][]  
![InBlock.gif][]if(lp && SHGetPathFromIDList(lp, szPath))  
![ExpandedSubBlockStart.gif][]\{  
![InBlock.gif][] str.Format("选择的目录为 %s", szPath);  
![InBlock.gif][] AfxMessageBox(str);  
![InBlock.gif][]  
![InBlock.gif][] ![dot.gif][]  
![ExpandedSubBlockEnd.gif][] \}  
![InBlock.gif][]else  
![InBlock.gif][] AfxMessageBox("无效的目录，请重新选择");  
![ExpandedBlockEnd.gif][]\}

选择文件对话框

![None.gif][] CString CDcPackerDlg::BootOpenDialog()  // 返回选择的文件名称   
![ExpandedBlockStart.gif][] \{  
![InBlock.gif][] CString strFile = \_T("");  
![InBlock.gif][]  
![InBlock.gif][] CFileDialog dlgFile(TRUE, NULL, NULL, OFN\_HIDEREADONLY, \_T("Describe Files (\*.cfg)|\*.cfg|All Files (\*.\*)|\*.\*||"), NULL);  
![InBlock.gif][]  
![InBlock.gif][]if (dlgFile.DoModal())  
![ExpandedSubBlockStart.gif][]\{  
![InBlock.gif][] strFile = dlgFile.GetPathName();  
![ExpandedSubBlockEnd.gif][] \}  
![InBlock.gif][]  
![InBlock.gif][]return strFile;  
![ExpandedBlockEnd.gif][]\}   
![None.gif][]  
![None.gif][] // 加载文件按钮   
![None.gif][] void  CDcPackerDlg::OnBnClickedSelectdec()  
![ExpandedBlockStart.gif][] \{  
![InBlock.gif][]// TODO: Add your control notification handler code here  
![InBlock.gif][] m\_strDescPath =""; //类的成员变量  
![InBlock.gif][]  
![InBlock.gif][]//"打开文件"对话框，选择文件，返回其路径  
![InBlock.gif][] m\_strDescPath = BootOpenDialog();  
![InBlock.gif][]  
![InBlock.gif][] ![dot.gif][]  
![ExpandedBlockEnd.gif][]\}

# [Windows--MFC选择文件对话框和选择文件夹对话框][Windows--MFC] #

选择单个文件对话框：

![复制代码][copycode.gif]

1 CString strFile = _T("");
    2 
    3 CFileDialog    dlgFile(TRUE, NULL, NULL, OFN_HIDEREADONLY, _T("Describe Files (*.jpg)|*.jpg|All Files (*.*)|*.*||"), NULL);
    4 
    5 if (dlgFile.DoModal())
    6 {
    7      strFile = dlgFile.GetPathName();
    8 }

选择多个文件对话框

![复制代码][copycode.gif]

1 void CBugReportDlg::SelectFiles( vector<CString>& all_sel_files )
     2 {
     3     CFileDialog dlg(TRUE, _T("*.jpg"), NULL, OFN_ALLOWMULTISELECT|OFN_HIDEREADONLY | OFN_FILEMUSTEXIST, _T("Image Files(*.jpg)|*.jpg|"), NULL); 
     4     dlg.m_ofn.lpstrTitle = _T("选择图片"); 
     5     CString filename; 
     6     if(dlg.DoModal() == IDOK) 
     7     { 
     8         POSITION fileNamesPosition = dlg.GetStartPosition(); 
     9         while(fileNamesPosition != NULL) 
    10         { 
    11             filename = dlg.GetNextPathName(fileNamesPosition); 
    12             all_sel_files.push_back(filename);
    13         }   
    14     } 
    15 
    16 }

选择文件夹

![复制代码][copycode.gif]

1 CString CBugReportDlg::SelFilePath()
     2 {
     3     TCHAR           szFolderPath[MAX_PATH] = {
          0};  
     4     CString         strFolderPath = TEXT("");  
     5 
     6     BROWSEINFO      sInfo;  
     7     ::ZeroMemory(&sInfo, sizeof(BROWSEINFO));  
     8     sInfo.pidlRoot   = 0;  
     9     sInfo.lpszTitle   = _T("请选择处理结果存储路径");  
    10     sInfo.ulFlags   = BIF_RETURNONLYFSDIRS|BIF_EDITBOX|BIF_DONTGOBELOWDOMAIN;  
    11     sInfo.lpfn     = NULL;  
    12 
    13     // 显示文件夹选择对话框  
    14     LPITEMIDLIST lpidlBrowse = ::SHBrowseForFolder(&sInfo);   
    15     if (lpidlBrowse != NULL)  
    16     {  
    17         // 取得文件夹名  
    18         if (::SHGetPathFromIDList(lpidlBrowse,szFolderPath))    
    19         {  
    20             strFolderPath = szFolderPath;  
    21         }  
    22     }  
    23     if(lpidlBrowse != NULL)  
    24     {  
    25         ::CoTaskMemFree(lpidlBrowse);  
    26     }  
    27 
    28     return strFolderPath;  
    29 }
