Richtextbox Change input

[CoDeR]

how can i make it so when the user inputs a text sting of maybe abc then clicks convert it makes a=1 b=2 c=3 so it outputs 123

in the button's click event:

Dim txt As String = RichTextBox1.Text
txt.Replace("a", "1")
txt.Replace("b", "2")
txt.Replace("c", "3")
RichTextBox1.Text = txt

While i < str1.Length
            str2 &= ((Asc(UCase(str1.Chars(i))) - 64).ToString)
            i += 1
        End While

I neglected to have it assign the replaced values to the variable, this works:

Dim txt As String = RichTextBox1.Text
txt = txt.Replace("a", "1")
txt = txt.Replace("b", "2")
txt = txt.Replace("c", "3")
RichTextBox1.Text = txt

Dim str1 As String = Me.TextBox1.Text
        Dim str2 As String
  Dim ch As Char
        For Each ch In str1
            str2 &= (Convert.ToInt32(Char.ToUpper(ch)) - 64).ToString()
        Next ch
        MsgBox(str2)

thanks for all the help, that part works great now but is there a way to select individual word without knowing what they are going to be. so when the button is clicked it will find the first word and put it into a variable

        Next ch
        MsgBox(str2)

Nice code.

The first word ends at the first space, so you can use String.Substring and String.IndexOf together to get the substring up to the index of the first space.
