You can use a graphics object to draw what you want to draw, convert it to a
supported image format, and then return this from a page. For example, you
can have an aspx page that returns content of type jpg, and uses a graphics
object to create this on the fly (which is handy for creating dynamic
charts, for example). However, you can't write directly onto the form
because, in the end, everything you write out from the server must be DHTML,
and how do you represent DrawArc in DHTML except by <img src="...">?
