To create a random string...


srsly? Did you start coding yesterday? Read a f*****g book. This is beyond basic. If you don't have a specific question about how to generate a random string, what are you asking?

thx for helping
Sub Main()
Dim s As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
Dim r As New Random
Dim sb As New StringBuilder
For i As Integer = 1 To 8
Dim idx As Integer = r.Next(0, 35)
sb.Append(s.Substring(idx, 1))
Next
Console.WriteLine(sb.ToString())
Console.ReadKey()
End Sub
