How to use ADSI to get list of open files on share

I'm trying to use ADSI to get a list of open files on a share. I've mimicked how to successfully do it in VBS, except when I do it in Delphi, I get a list of the shares, rather than the open files.

For example:

  VBSCRIPT:
-----------------------------------------------------
'  Bind to a file service operations object on “servername" in the local domain.
Set fso = GetObject("WinNT://<servername>/LanmanServer")

' Enumerate resources
If (IsEmpty(fso) = False) Then
For Each resource In fso.resources
 
  ' Add Item to some list
Next
End If
------------------------------------------------------

Now in Delphi I tried doing to same thing:

Dephi:
-----------------------------------------------------

hr := ADsGetObject('WinNT://<servername>/Lanmanserver',IADsContainer,Container);
  if Failed(hr) then exit;

  hr := ADsBuildEnumerator(Container,e);  // start enumerating
  while SUCCEEDED(hr) do
  begin
    // get the next contained object
    hr := ADsEnumerateNext(e,1,varArr,lNumElements);
    if (lNumElements<=0) then
      break;

    IDispatch(varArr).QueryInterface(IADs, item) ;
    ListBox1.AddItem(item.ADsPath,nil);
 end;

------------------------------------------------------  

The VBScript seems to return the names of files and folders open on the share, however the delphi code returns the actual shares themselves, with no mention of the files opened. Anyone know what I have to do to get the delphi code to return the actual files?

The VB Script is calling a method called resources. It's actually enumerating the Resources property, not the container itself. (At least, if I'm not mistaken.) The only ADSI component that has Resources is the IADsFileServiceOperations property so I think you need to use:

var Container: IADsFileServiceOperations;
begin
  hr := ADsGetObject('WinNT://<servername>/Lanmanserver',IADsFileServiceOperations,Container);

instead. But this is a bit of a wild guess. I can't test this right now.The Resources is an IADsCollection type which you can enumerate again, btw.

I'm going to give it a try here - i'll let you know. I thought it might have something to do with that.
