I'm drawing an image in a panel control with this sentence in the Paint
method:
e.Graphics.DrawImageUnscaled(Image, panelImage.AutoScrollPosition);
The problem is that I only want to paint a region of the image specified by
a Rectangle object. I can do it with:
e.Graphics.DrawImageUnscaled(Imagen, myRectangle);

I am designing a program in which the user will be drawing, lines,
circules and so on, on a paint control which displays an image opened
by the user. "It's like there is a map on the picturebox control and
the user draws some raads on the map."
I am using System::Drawing::Graphics class, first I assign the handle
of the picbox where the user wil draw:
graphicsSurface = System::Drawing::Graphics::FromHwnd(
picBox->Handle );

then somehow stream it using the response object to the Webcontrols.image.

my form. I can reproduce the exception consistently, but
it seems to be timing dependent. Here is what happens:
I have a subform that I open, load an image from a file
into my PictureBox, take some user input, then I hide the

I have this code that writes a pie chart in a asp.net page, but I want to
use it in a server control.
When I try I get a error on the last line "Response.OutputStream"
Obviously there is no response object but how do I write it to screen?

Dim objGraphics As System.Drawing.Graphics
objGraphics = System.Drawing.Graphics.FromImage(objBitmap)
