System.IndexOutOfRangeException : when the index is less than zero or greater than the length of String Object,this exception is thown

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Dim str As String = "allpctips.com"
Dim singleChar1 As Char
singleChar = str.Chars(3)
