Retrieving Extended File Properties via delphi

Question

When you right-click a file in Windows Explorer and select Properties from the menu, a dialog box displays basic properties for that file.

I'm trying to get these properties (keywords, comments, title...) for word files in a folder.

I modified a code that i found somewhere and it works well in vba (MSWord office macro):

Private Sub CommandButton1_Click()

Dim arrHeaders(35)

Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.Namespace("C:\Scripts")

For i = 0 To 34
  arrHeaders(i) = objFolder.GetDetailsOf(objFolder.Items, i)
Next

For Each FileName In objFolder.Items
  For i = 0 To 34
    MsgBox i & vbTab & arrHeaders(i) & ": " & objFolder.GetDetailsOf(FileName, i)
  Next
Next

End Sub

So I'm trying to make it work in object pascal in delphi. I'm still missing some of the syntax.

I was able to transform half of the syntax:

procedure TFormAFDetails.Button1Click(Sender: TObject);
var
  ObjShell, ObjFolder : Variant;
  FileProp : array of string;
  FName : String;
  I, J : Integer;
begin
    SetLength(FileProp, 35);
    ObjShell := CreateOleObject('Shell.Application');
    ObjFolder := ObjShell.NameSpace('C:\Scripts');

    for I := 0 to 34 do
      FileProp[I] := ObjFolder.GetDetailsOf(ObjFolder.Items,I);

    for FName in ObjFolder.Items do
    begin
      for J := 0 to 34 do
        ShowMessage(FileProp[J]+' : '+ObjFolder.GetDetailsOf(FName,J));
    end;
end;

The part "for - in - do" won't work as it says

//for -in statement can't operate on collection type 'variant' 

Can anyone help me out please?

The answer to the question that you ask is:

for I := 0 to ObjFolder.Items.Count-1 do
begin
  FName := ObjFolder.Items.Item(I);
  ....
end;    

The code looks a little odd though, especially the use of that magic value 35.
