Form bouncing against the Start Menu at exit! 2.0

By | 2002-06-01

This code is a must have! It’s cooler than the “Cool Form Close” code , cooler than the “Implode and Explode” code! So what does it do? When you close you program a really cool effect will appear. Your form will shrink so just the Titlebar is being showned, then the titlebar accelerates and bounces againt the start menu, goes up in the air, bounces a couple of more times and then disappears behind the Start Menu! Way Cool! This code is a very advanced one but it’s really easy to use, try it!!! Includes functions for getting the top position of your start menu and offcourse the bounce code! New for ver. 2 is that the form now can bounce sideways if you edit the code just a little tiny bit, now also supports maximized windows!!!

Inputs

None really, you might wanna change the speed property in the code if you can find it.

Assumptions

Paste the ‘main code’ into the form_unload section. The declare the variables (IMPORTANT!)

Returns

A really cool ‘bouncy’ effect. I use it always in my progs!

Side Effects

None, but their might be bugs..

Me.Width = 4000
GoAgain:

If StartAt >= 10000 And Me.Top >= HeightOfStartMenu Then

Exit Sub
End If
StartAt = StartAt + 1000
Speed = Speed - 5
'// Decrease speed with 5 after each "bounce",
'// You can change the value all ya want :)
If Speed <= 0 Then
Speed = 5
'// If the Speed value gets under zero i will
'// automatically turn into 5 (cause if it don't
'// It will stop or do something crazy
End If
