What is the graphics object

[Michael Culley]

I've been using the graphics object to paint an entire usercontrol. I've
come across a few questions that I cannot find the answer to in books. First
of all, in terms of APIs, what is the graphics object, is it a device
context? Why do I have to use Me.CreateGraphics all the time? I guess what
I'm after is some general info regarding what is happening under the hood
when I use the Graphics objects.

Cheers

It's not correct to say it *is* a device context, but you're close. The
Graphics class encapsulates a device context and methods you invoke on a
graphics object have an effect on that device context.

>Why do I have to use Me.CreateGraphics all the time?

That's roughly equivalent, conceptually, to GetDC in old-school windows
programming.
