Queries for Derez and Filippo

Well, not exactly as you ask for but I updated, see the help file. Thanks again for the debugging

I'm not sure that the question is aimed at me

Agraham - yes it was aimed also to you, and I always appreciate, value and learn from your inputs.

Just reading your comments for the library update on the other thread, you say you check for empty input strings. Ummm, that wasn't exactly the problem. When I said "It seems to be expected that the item will be found", I didn't mean that the search was failing because of the input string being empty, I meant it failed because the target was not in the tree.

So you have definitely improved it by checking the input, and a return of "-1" is as good as any, but, sadly, my original problem is still there.

In your sample program, tree_1.1.sbp, type in the text "mummy" then search, you'll see what I mean.

OK OK, when explained slowly I understand fast...
corrected:

if(st.Length > 0)
    {return st.Substring(0,st.Length-1) ;}
else
    {return "" ;}

That's the one cheers!

And I do like the way we can distinguish between the two cases "-1" and "". Very good!
