Dim SearchWithinThis As String = "Mummy loves Daddy and loves me too"
Dim SearchForThis As String = "Mummy"
Dim FirstCharacter As Integer = SearchWithinThis.IndexOf(SearchForThis)
You can also change "Mummy with a string connected to a textbox, for a custom search.
It'll return a number also so
1 = True
0 = False
(Might be backwards on that, but it can be easily checked)
