PRB: IShellFolder::GetDisplayNameOf Returns Names with GUIDs

SYMPTOMS

On Windows 2000, calling the desktop's IShellFolder::GetDisplayNameOf with SHGDN_FORPARSING for a namespace extension returns a name with GUIDs in it rather than actual display names.

For example, the following code:

LPITEMIDLIST   pidl = NULL;

SHGetSpecialFolderLocation(NULL, CSIDL_CONTROLS, &pidl);

if(pidl)
   {
   IShellFolder   *pDesktop;

   SHGetDesktopFolder(&pDesktop);
   if(pDesktop)
      {
      STRRET   str;
      TCHAR    szText[MAX_PATH];

      pDesktop->GetDisplayNameOf(   pidl, 
                                    SHGDN_FORPARSING, 
                                    &str);

      pDesktop->Release();
      }
   }
				

returns a name such as: rather than the following expected text: Some folders may return a name such as: instead of returning the GUID for "My Computer."
