Here is the function to generate microsoft styel password using uppercase letters and numbers

Private Function PassWord()
st = ""
For i = 1 To 4: For j = 1 To 5
xt = Int(Rnd(5) * 36): If xt > 9 Then xt = xt + 7
st = st + Chr$(48 + xt)
Next: st = st + "-": Next
PassWord = Left$(st, Len(st) - 1)
End Function
