Is it possible to capture the maximize event of any open form? I want to
create an app that sits in the tray and performas a tast every time a window
is maximized.

window is maximized.

Handle the form's 'Resize' event and compare the value of its 'WindowState'
property to 'Maximized' threre.

I'm not handling th maximize from within the application though. What I
want to to do is override the maximize functionality of any window in the
system, so I need some kind of hook or system where I can capture any
applications window maximize event

As I understand it, Jeremy wants to intercept resize events on windows in
all running applications, not only the forms of its app. I believe this is
not possible using managed code only. To accompilsh susch a task one needs
to resort to windows hooks (WH_GETMESSAGE). Global hook of this kind cannot
be implemented with managed code. AFAIK it can be implemented in unmanaged
DLL and used with PInvoke.
