Here is a quick / rough way that I would count the characters in a string

    Dim s As Char() = TextBox1.Text.ToCharArray
    Dim p As New Dictionary(Of Char, integer)

    For Each chars As Char In s
        'ignore the spaces
        If Not chars = " " Then
            'count the occurances of the character
            Dim i As Integer = s.Count(Function(r) r = chars)

            'if the letter is not in the dictonary
            If Not p.ContainsKey(chars) = True Then
                p.Add(chars, i)
            End If
        End If
    Next

Please do not scream at me. Thank you.

Why is common sense not common? Never argue with an idiot. They will drag you down to their level where they are an expert. Sometimes it takes a lot of work to be lazy Please stand in front of my pistol, smile and wait for the flash - JSOP 2012

How do you know that, VB programmers aren't case-sensitive ;P

I would only tolerate it if my "option strict" was on.
