        'Get the length of characters in the text box
        Dim textBoxLength As Integer = TextBox1.Text.Length
 
        'Format the textbox character length by dividing by 11 (phone number length) and subtracting 1 (total number of commas to add)
        Dim textLength As Integer = textBoxLength / 11 - 1
 
        'Make i an integer which is equal to the textLength variable.  This is not necessary, just pretty
        Dim i As Integer = textLength
 
        'Loop in reverse order, inserting a comma every 11th character
        'We are looping backwards since the length of the textbox text changes with every insertion
        Do Until i = 0
            TextBox1.Text = TextBox1.Text.Insert(11 * i, ",")
            i = i - 1
        Loop
