Customization of File Open Dialog????

Could somebody tell me as to whether it is possible to customize the MFC's common File Dialog
such that, on triggering, it displays only the FOLDERS from the current directory and not the FILES????
I have referred a couple of books, but couldn't find a pointer on how to go abt doing it.
Any help would be appreciated..  Thanx in Advance

Hi,
You can get a sample for this in DIRPK example on ftp://ftp.microsoft.com/ Softlib\Mslfiles directory.
If you have any problems, please get back to me.

Hi Mr. Rajesh

I went to the ftp directory you mentioned (softlib/mslfiles).
But I couldn't find any reference to the file you had mentioned
(DIRPK).  There is neither a file nor a directory in the name of DIRPK.
Thanx for the effort ......

Sorry Mr. Jmmougeolle, the file (DIRPK.EXE) is not to be found even in the directory u mentioned.  Here is the complete listing of the directory ftp.microsoft.com/Softlib;

Mslfiles (directory); README.TXT; SOFTLIB.EXE; WDL.TXT; WNTDL.TXT

These are the only 5 listings I found in the place you mentioned.
There was no sign of DIRPK.EXE ..........
Thanx for the effort though......

Hi,
If you are not able to find that sample, I will mention briefly what is to be done :
1. Follow the instructions given in "Directory Picker Sample Using Modified CFileDialog" article in Knowledge base section of VC++ documentation. Hope you will find that.
Then, in OnInitDialog() of your class derived from CFileDialog,
do following steps :
CMyFileDialog::OnInitDialog()
{  
// This is for showing/hiding the unneeded controls on the CFileDialog template
        GetDlgItem(stc2)->ShowWindow(SW_HIDE);
      GetDlgItem(stc3)->ShowWindow(SW_HIDE);
      GetDlgItem(edt1)->ShowWindow(SW_HIDE);
      GetDlgItem(lst1)->ShowWindow(SW_HIDE);
      GetDlgItem(cmb1)->ShowWindow(SW_HIDE);

 // edt1 is the ID of edit control in the file dialog which //displays the name. So first it's made invisible ( by SW_HIDE ) //and then set       any value so that file dialog gets dismissed when //OK button is clicked.
      SetDlgItemText(edt1, "Junk");
      GetDlgItem(lst2)->SetFocus();

      CFileDialog::OnInitDialog();

      
      return FALSE;  // return TRUE unless you set the focus to       a control
}

Then in the handler for your customised dialog, you can get the directory path as follows:
CMyApp::OnCustomizedFileDialog()
{
  if (IDOK==cfdlg.DoModal())
    {
     CMyFileDlg  cfdlg(FALSE, NULL, NULL, OFN_SHOWHELP |          OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT | OFN_ENABLETEMPLATE,      NULL, m_pMainWnd);

       WORD wFileOffset;
       char szBuffer[128];
   
       wFileOffset = cfdlg.m_ofn.nFileOffset;  //for convenience

       cfdlg.m_ofn.lpstrFile[wFileOffset-1]=0; //Nuke the "Junk"

       wsprintf(szBuffer, "Selected directory is %s",
                (LPSTR)cfdlg.m_ofn.lpstrFile);

       AfxMessageBox((LPSTR)szBuffer, MB_OK);
}

You will have to follow the steps carefully for including the template for CFileDialog in your .rc file.
In your class declaration, you have to put following code to inform that you are going to use this template for your file open dialog.
enum { IDD = IDD_NEWFILEOPEN};
Hope this clarifies your problem. I have given almost all the code from the DIRPK sample itself, so there shouldn't be much problem.

There is a slight mistake in the code provided in my answer. You might have been able to make it out :
The line
CMyFileDlg cfdlg(FALSE, NULL, NULL, OFN_SHOWHELP | OFN_HIDEREADONLY |OFN_OVERWRITEPROMPT | OFN_ENABLETEMPLATE, NULL, m_pMainWnd);
should be before
if (IDOK==cfdlg.DoModal())
Please take a note of that.
