Best Answer

Function RandomString(cb As Integer) As String

    Dim rgch As String
    rgch = "abcdefghijklmnopqrstuvwxyz"
    rgch = rgch & UCase(rgch) & "0123456789"

    Dim i As Long
    For i = 1 To cb
        RandomString = RandomString & Mid$(rgch, Int(Rnd() * Len(rgch) + 1), 1)

End Function

Please be aware that the built-in random number generator is not cryprographically secure so a function like this should not be used to generate passwords.
