Make sure you're not calling CoInitializeEx with argument other than
COINIT_APARTMENTTHREADED.

If COM is initialized on the current thread with COINIT_MULTITHREADED mode,
the shell functions (including the file dialog) won't work.

Hello NG,

I see a strange behaviour of CFileDialog on some, but not all computers.
When I open a dialog in Windows XP with

  static char hFilter[] = "jpg Files (*.jpg,*.jpeg)|*.jpg;*.jpeg|All Files
(*.*)|*.*||";
  CFileDialog fdlg(TRUE, "", "",OFN_FILEMUSTEXIST| OFN_HIDEREADONLY,
hFilter, this);
  if (fdlg.DoModal() == IDOK) ...

When I press left on "My Computer", the file list don't show files and
directories. But there are e.g drives and network drives. When I press "My
documents" the file and directory list is shown correctly.

Even when I swap the filter definitions to
  static char hFilter[] = "All Files (*.*)|*.*|jpg Files
(*.jpg,*.jpeg)|*.jpg;*.jpeg||";
the "My Computer" does not show anything.

Why is it?

Thanks for help,
Guido
