As far as I know you can do whatever you want in your Form_Unload event. If you want to paint the Mona Lisa on your form at unload go ahead.

See http://www.planet-source-code.com/vb

And do a search for form effects. There are all sorts available.

There are so many things you can do, but they're all based on the same principle.

The following is code that lets your form dwindle away. If you want any other effects, just modify.

Dim dblDiff As Double
dblDiff = Height - ScaleHeight

Dim intSpeed As Integer
intSpeed = 2

Do While Height > dblDiff
Height = Height - intSpeed * Screen.TwipsPerPixelY * 2
Width = Width - intSpeed * Screen.TwipsPerPixelX * 2
Top = Top + intSpeed * Screen.TwipsPerPixelY
Left = Left + intSpeed * Screen.TwipsPerPixelX
DoEvents
Loop
End If

End Sub
