I am looking for a solution to add on-line drawing tool
to a phpBB discussion board.
The idea would be that the users can draw their own
simple drawings with the tool and attach them easily
as images in the discussion. The idea is to easily
add small drawings to the postings.
The drawign tool should be easy to use and learn.
It should be easily integrate to the phpBB system.

I get an out of memory exception when attempting to excecute the
following code:
original = System.Drawing.Image.FromFile(file.FileName,true);
I ONLY get this exception when the file is in the "My Documents"
folder or subfolders. If the file lives anywhere else on the hard
drive, I have no problems.
What could be going on here?

Hello all,
I have a class which includes a method to create a chart. I want to be able
to call this method from asp.net code as well as windows application code,
so I have sketched it out as returning a bitmap instance.
In my asp.net code I think I should call this method to return a bitmap and
then somehow stream it using the response object to the Webcontrols.image.
Is that right? The image object is on a page with a number of...

Dear colleagues,
I refer to your help with specific graphic problem. It is
necessary to create a viewfinder in graphic application.
It seems that the algorithm is simple: just draw lines
in specific position in according to value of some
controls, track bars, for example. Next read the track
bars value to find the coordinates of lines cross.
It works, but I can not get real cross because the
background image is being deface by lines...

I was running into the System.Drawing.Image.FromStream "parameter is
not valid" on some of the images I was retrieving from a blob column in
Sql Server. I thought there were corrupt images as almost all worked
(all are gifs), and only a few broke when this line ran: Image img =
Image.FromStream(ms); here is the original code:
b = (byte)dt.Rows.ItemArray;
//b.ToString()
ms = new MemoryStream();
ms.Write(b, 0, b.Length);

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)

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
