CFileDialog "MyComputer" not shows drives and files in directories

Hello NG,

I already posted on 16. September that the CFileDialog does not show the "My
Computer" drives, but shows files and dirs in e.g. "My files".
Then you helped me to use CString for the filter string.

But this was only temporarily. Now the files in a directory are not shown
when there are a lot of files in it. Ordering the files and the CFileDialog
shows the rest again. So there must be a too big number of files to be
shown, so the CFileDialog not shows them at all.

But the File-Open-Dialog is ok in standard Windows editor. But not with
developer studio's CFileDialog. "My Computer" is not shown here.
I cannot find an update or patch for the developer's CFileDialog.

Reading in internet, people only say to reinstall Windows XP. But my
customer don't want to reinstall.

Problem seen on Win XP SP2, with Developer Studio VC 2003 (V7.1).

What can I do?
Thanks for help,
Guido

Here my code:

CString hFilter = "All Files (*.*)|*.*||";
CFileDialog fdlg(TRUE, "", "",OFN_FILEMUSTEXIST| OFN_HIDEREADONLY,
hFilter,this);
if (fdlg.DoModal() == IDOK)
   {
      m_szFile = fdlg.GetPathName();
   }
