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.

Hi,
I'm getting "object is currently in use elsewhere" when I use
System.Drawing.Graphics.MesureString.
This is what I do:
My controls use a utility class the helps it to mesure strings.
To get the best performance for the utility class, its members, as well as
the System.Drawing.Graphics object, are static:

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...

I find Bitmap.Save works for WMF files but Bitmap.FromFile does not.
If I use FromFile on a WMF file that came with VS I get an exception.
If I use it on a WMF file created with Bitmap.Save I don't get an exception
but it appears the Bitmap is blank.
Can anyone share some knowledge on this?

I am fairly new to .Net and C# but am familiar with the Win32 API.
I wish to set the pixels of the client area of a window one at a time
with a specific color. I have so far discovered that System.Drawing.Bitmap
has a SetPixel() method but I can't seem to find out how to have the bitmap
displayed. I would actually like to have the pixels appear as I set them.
Regards

I want to use the System.Drawing.Image class. According to the help file,
this is an abstract base class. Because it is supposedly abstract, I created
another class that inherits from it. However, when I did this I got the
following error:
'System.Drawing.Image.Image()' is inaccessible due to its protection level
Looking at other online examples, I found that the proper way to use it is
like this:

I am doing an app (C# 2.0) where you can draw in a panel with your mouse in "real time". I actually have 2 problems;
1- it does not really is "real time", if your mouse move fast or very fast the line is added after a very small delay.
2-Because I use AddLine(), it adds very short lines from one point to another and it does not give a very good result. Also because of this and my "not real time" problem, when the mouse moves fast it adds...

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 objBitmap As New System.Drawing.Bitmap(400, 440)
Dim objGraphics As System.Drawing.Graphics
objGraphics = System.Drawing.Graphics.FromImage(objBitmap)
objGraphics.Clear(Drawing.Color.White)

I have a logical drawing space much bigger than the viewport (the
screen) and I'd like to center the viewport (the screen) to be at the
center of the logical drawing space. After following the excellent
transforms specified on Bob Powell's site, I still wonder if there's
an easier way of centering it than the following procedure?
Here is what I do now (it's awkward but it works):

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
