Hi Kmiller,

In fact I made a component, descendant from TListView that has a SaveToFile method.

If you can wait till Monday I can send you the source code (It's in my office...)

Bye,
Itamar

The easiest way is to use something like this:

procedure TForm1.SaveBtnClick(Sender: TObject);
var st : TFileStream;
begin
  st := TFileStream.Create( 'c:\test.res', fmCreate );
  st.WriteComponent( ListView1 );
  st.free;
end;

procedure TForm1.LoadBtnClick(Sender: TObject);
var st : TFileStream;
begin
  st := TFileStream.Create( 'c:\test.res', fmOpenRead );
  st.ReadComponent( ListView1 );
  st.free;
end;

however this proc reads the settings for the ListView1.too. If you don't like this you can create invisible mListView and assign items from visible to invisible.

You can of course travell over the items with for i:=0 to ListView1.Items.Count and save nodes and subnodes.
