Hi all -

I'm a complete noob when it comes to using the system.drawing
namespace.

I'd like to draw a control to an image instead of on screen (the object
shouldn't appear on screen at all). Any ideas?

I was trying to use control.createGraphics, but it doesn't appear to
have any options to save the data to a different surface...

Is there any way to use the graphics object to draw to multiple
surfaces simultaneously?

Thanks,

-Mark

What does that mean?

Instead of drawing it to the form surface (or simultaneously), I'd like
the control to paint itself onto a blank canvas in memory, so I can
save that as an image.

In this case, my end goal is to save a thumbnail of a web page *WITHOUT
SHOWING IT ON SCREEN*. However, this same technique could be used to
save a frame of a video, or anything else, for that matter.

No, I know how to draw to a bitmap. I'm trying to get (essentially) a
screenshot of a control without that control ever appearing on screen.

I can draw a bitmap.

I can get a screenshot if it's on screen.

What I can't do (yet) is have the control, without drawing itself to
the screen, draw itself to an image instead--(or some other technique
that would have the same result).

I've tried putting the control on an offscreen form and trying to
bitblt that, but it's not working.
