Sliding windows?

I like the flat look of the Visual Studio environment, and have been trying to write something that allows 'panels' to dock against a side and particular to 'slide' in and out.

I've tried using the Windows API AnimateWindow, but it only works on forms.
So I tried writing a MDI form with the new forms sliding in and out of the blank space, but you get a window box around the blank area of the parent form.

Any ideas how this might be done?

Doesn't help, because there is a whole solution written in C, and it is difficult to get to grips with it.

Can you at least point me to the area I need to be looking at.
Is this Windows API?
Is this a clever MDI without borders?
There seems to be a timer at work, but does this involve redraws?

Thanks again.
Thanks for your previous help.

For the slide it is real easy:
Add a timer to your form
On the click method of a button (whatever) enable the timer
On the timer_tick method move your item in increments:

'Assumes that Panel1 is shifted to the left of the form edge
Dim XPos as Integer
XPos = Me.Left  'Set XPos to the left of the form

Panel1.Left += 2 'Move the panel to the right by 2
If Panel1.Left >= XPos Then Timer1.Enabled = False 'If the left edge of the panel hits the left edge of the form, turn the timer off.

The docking is a little more engaging, but can be done. You have to do a lot of checks. See this site: http://www.divil.co.uk/

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Sorry, but the form looks awful when moving.

Use a panel instead of a form...Also adjust the timer count and the increment. Depending on how you set it, the movement is smooth.

I've been trying to do this without much success. Redrawing the controls etc. takes too long for it to work neatly. AnimateWindow API does it neatly, but it only works on forms.

Below is posted code from a test app I threw together. I was using hot keys (adding labels) to slide in/out the panel (in the window's generated code it was called "nicepanel1".
The form has two timers a panel and a few buttons. Look it over and see how the slide effect happens.

Don't worry about that...it's a hotkey component that I use to assign system wide hot keys (like ctrl + P) to my apps.
