Inserting at Position

[AceInfinity]

Just wondering why you use the replace() function instead of insert()? I only vaguely read through your code, still a little confused.

Dim str As String = "this is string value"
str = str.Insert(str.IndexOf("string"), "my ")

edit: Disregard my post... I didn't see this was for asp.net, I assumed some kind of vb script.
