Alright, well as a sidenote, you should avoid the compatibility namespace. i.e. Don't use Split()

Code:

Dim Words As String() = Split(ToChange, " ")

Split() != String.Split().

Aside from that, you can use an enumerator on a String object; no need to redundantly cast it to a char array to iterate the internal characters.

You said you were going to post up your own challenge?

I was, but I've lost the sheet of questions for it. I'll try and find it this coming week :thumbsup:
