I'm making a 'whiteboard' application.
I'm trying to have 2+ connected users able to draw at the same time.
However, if User1 draws a line, when User2 is drawing, on User1 screen,
it will draw another line, connecting User1's, and User2's current X,Y
position.
Same thing happens with User2.
But User3, and User4 is not drawing, and see the lines drawn individually.

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.

Hello, (total GDI newbie)
I'm having trouble drawing just a simple line to display in a picturebox. I
just want a straight, dotdash line.
I have two methods, one works and one doesn't (it cause an exception to be
thrown):
This one works but it's not the results I want.

I tried searching the newsgroups to see how do you draw a dotted line but I
was unable to find an answer, drawing a straight line is very easy but not a
dotted one.
So the question is, how do I draw a dotted line?
Thank you.

I want to know if the mouse is over (hitting) a line. Therefore I created a
Region object that holds the line and use the IsVisible() method to test if
the mouse hits the line. It doesn't work! In the little program below I
create two Regions: one is square, the other is a line. Hit testing works on
the square-Region, not on the line-Region.
How can I do a hit-test over a line?
//namespace HitTest
namespace HitTest

I try to define a line with the length of 1 unit (1 pixel) that is, in fact,
just a point on the screen. But when I draw it with a wide pen with the
appropriate StartCap and EndCap (Round), it will appear as a dot.
I can think of a way to define a 1-pixel long line but it is ugly and
clumsy.
I subtract .5 from the given pixel's X and Y coordinate for the first
System.Drawing.PointF structure, and add .5 to the other PointF stucture. It...

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
