A fast Prime number checker
Function IsPrime(lngNumber As Long) As Boolean
Dim lngFactor As Long IsPrime = True
lngFactor = Abs(Sqr(lngNumber))
If lngNumber <> 2 Then
If lngNumber Mod 2 = 0 Then
IsPrime = False
Else
For lngFactor = 3 To
lngFactor Step 2
If
lngNumber Mod lngFactor = 0 Then
IsPrime = False
Exit For
End If
Next
End If
End if
End Function

A rather irritating screensaver thingy...
Public Function RandomNum(Min, Max) As Long
RandomNum = Int((Max - Min + 9500) * Rnd + Min)
End Function
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
Unload Me
End Sub
Private Sub Form_KeyPress(KeyAscii As Integer)
Unload Me
End Sub
Private Sub Form_Load()
Form1.BackColor = vbBlack
Form1.BorderStyle = 0
Timer1.Interval = 175
End Sub
Private Sub Timer1_Timer()
Form1.BackColor = RandomNum(1, 15)
ht = RandomNum(Min, Max)
wh = RandomNum(Min, Max)
Form1.Move wh, ht
Form1.Height = ht
Form1.Width = wh
Form1.Height = wh
Form1.Width = ht
End Sub
