VB.NET Random Form Name!

Hey Community

Here I have a source code where you name your form Random is changed!

Code:

Imports System.Text

Dim str As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
        Dim r As New Random
        Dim sb As New StringBuilder
        For i As Integer = 1 To 20
            Dim idx As Integer = r.Next(0, 35)
            sb.Append(str.Substring(idx, 1))
        Next
        Me.Text = sb.ToString

change but still. exe name again is safer!
