Hello Mike,
Each Windows.Forms.Control consumes a windows handle as well as lots of
other resources, and they don't handle transparency well. So there are
advantages to retained mode graphics systems, if you are talking about
single graphical objects that respond to mouse events. Look at the link in
my signature for an example.

I'm developing some simple user-drawn graphical controls and looking for
the most efficient way of going about it.
Initially I had the default VS control project which derrived from
'UserControl' with all it's baggage. Having a look up the inheritance
tree it looks to me that this is designed to be a scrollable control
container by default which I did not require, and so inheriting from
'Control' instead worked just fine.
Having a look through the Control class (metadata) it seems that there are
a lot of properties which don't really apply to my control though, however
going up a level further to 'Component' looses some of the required
functionality (namely creating a window, painting and so on.)
Is the standard practice in this case to just use Control, or is there a
more appropriate base class to work from?
Cheers,
Mike
