Calling IOfflineFilesCache.IsPathCacheable with Delphi

I need to use the method IsPathCacheable in the IOfflineFilesCache interface to check to see if a UNC path is being cached:

Has anyone defined this interface for use in Delphi (I'm using Delphi 2010) or know of another way to achieve thi开发者_如何学Pythons (aside from defining it myself)?

Thanks

You can use WMI to access offline files: The Win32_OfflineFilesItem class can be used to enumerate them and inspect their properties.

To spare you the hassle of setting up WMI for yourself I would suggest the excellent Delphi WMI Class Generator. It will generate the unit uWin32_OfflineFilesItem.pas containing a wrapper class called TWin32_OfflineFilesItem which can be used as follows:

uses uWin32_OfflineFilesItem;

var
  OfflineItems: TWin32_OfflineFilesItem;
  i: Integer;
begin
  OfflineItems:= TWin32_OfflineFilesItem.Create;
  for i:= 0 to OfflineItems.GetCollectionCount-1 do
  begin
    OfflineItems.SetCollectionIndex(i);
    Memo1.Lines.Add(OfflineItems.ItemPath);  // <-- this gives the UNC path
  end;
end;

(There is one other unit involved, uWmiDelphiClass.pas, which comes with the Delphi WMI Class Generator download.)

You can use the same approach to access the methods of Win32_OfflineFilesCache (which corresponds to IOfflineFilesCache). Unfortunately there the method IsPathCacheable is missing, thus the need to use above approach.
