Extending the toolbarbutton control

[geoff]

I am trying to learn how to create my own controls. I want to create
my own toolbar which would be similar to the .net toolbar except that
my version would allow 3 images per button (off, over, down). I
haven't been able to find anything on msdn on extending the
toolbarbutton control to add in this functionality. Has anyone seen
an online tutorial on the subject or something related? Thanks.

Of all controls to extend, you've chose one which is implemented by a
win32 control (not 100% C#), so you'll need to write it from scratch
(can't extend)
