Hi
I am developing a Dot net application (involving image processing) on
a uni processor. It works well on my machine. I then take all my code
on a multi processor, build and run the application there. There is
performance degradation.
The usual performance of the application on MP machine is better than
that of uni processor machine. But the performance of MP degrades when
it comes to the multi-threaded part of the application. I am...

Hello everyone. I'm creating a simple bingo game. After the board is
drawn on the screen, I try to get input from the user. If they enter an
'm', the application marks the random letter and number on the bingo
board. If they type 'b', the application checks for bingo... you get the
point.
Now, if no input is received within x seconds, I would like to go on
with the rest of my application (drawing another letter and number,
printing the...

I have created an application that will dynamically load other DLLs (plugins).
The new plugin is a winform with an embedded IE Browser.
I am wanting to have the form to run in its own thread. This would allow for other
plugins and the main application to be free to do other work. I have written a
little TestDriver for the plugin and am having some difficulty.
If I don't use threads everything works just fine. If I do use threads, upon...

I have a .NET console application that is kicked off by a .NET Windows
service. They communicate via .NET Remoting, although there isn't much
communication between the two while the console app is running. There can
be, and are typically, several instances of the console app running at the
same time communicating back to the service.
The console app creates a delegate to do some work while the main thread
waits on a ManualResetEvent to...

Hi,
I am creating a multi-winform project. Everything has been working
fine, except after I perform an update to the database and decide to
Exit the winform after the update operation is complete.
I have error handling in my code but not on the dispose method. I call
the dispose method exiting the application using the code below but
results in this error message
"An unhandled exception of type 'System.NullReferenceException'

Hi all,
I'm putting together a simple help module for my applications, using
html files stored in the application directory somewhere. Basically it
sets up a basic web server, and then uses the webbrowser module to
display it in the users browser. I have it set up to call sys.exit(0)
if the url quit.html is called, but for some reason (on Windows XP via
the cmd.exe shell) python won't let me have the console back. I get the
System Exit...

Hi All,
I think I'm missing a basic bit of understanding with modal forms.
This is the problem I have:
1. User clicks button on form, event handler throws an exception.
2. In catch block a form is shown modally (i.e. errForm.ShowDialog
()).
3. When the user closes the dialog the form image stays on the screen
and the app stops painting.

As far as I know, the C Standard has no mention of multi-threaded
programming; it has no mention of how to achieve multi-threaded
programming, nor does it mention whether the language or its libraries
are suitable for multi-threaded programming.
For people who are fond of portable C programming, what's the best way
to go about multi-threaded programming?
I've been reading up on POSIX threads a little, they seem pretty
ubiquitous....

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
