Public Function GetRandomString(ByVal iLength As Integer) As String

Dim sResult As String = ""
Dim rdm As New Random()

For i As Integer = 1 To iLength
sResult &= ChrW(rdm.Next(32, 126))
Next

Return sResult
End Function

No silly it's a function that you can call, here's an example:

Module Module1    Sub Main()        Console.WriteLine(GetRandomString(10)) ' Provide the size as a parameter        Console.ReadKey()    End Sub    Public Function GetRandomString(ByVal iLength As Integer) As String        Dim sResult As String = String.Empty        Dim rdm As New Random()        For i = 1 To iLength            sResult &= ChrW(rdm.Next(32, 126))        Next        Return sResult    End FunctionEnd Module

Well you call it (on the button click event in your case) and then the return value can be assigned to something... such as a text field's text property for instance. Or passed to the console as I did.
