Is there any way that I can modify my Windows.Form when I press the "Close-Box" (the "X")?

Background:
My app is running in the system tray, with WindowsState.Minimized and ShowInSystemTray == false.

When I select "Open app" from my ContextMenu, I change WindowsState from Minimized to Normal, which means that the app "pops-up" just the way I want it to do. So far, so good.

Now, I would like to make 2 things happen:

1) Disable the MaximizeBox (not remove it)
2) Change the behaviour when I click the close box, I want it to go back to its original form (running in the system tray)

If you have any good advice or pointers to where I might find information, I would be very grateful.
