Hello,
I have an application that processes thousands of files each day. The
filenames and various related file information is retrieved, related
filenames are associate and placed in a linked list within a single object,
which is then placed on a stack(This cuts down thread creation and deletions
roughly by a factor of 4). I create up to 12 threads, which then process a
single object off of the stack. I use a loop with a boolean...

Hi,
I have a GUI application that responds to events coming from an externaql
application. In the implementing code for the event I need to create a GUI
control and "parent" the control into the GUI. Doing this directly fails, it
is not allowed to parent a control that was not created on the main GUI
thread into the main GUI through another thread (an exception is thrown on
"control.Parent = container;").
So I have to create the...

Hello,
I have a multithreaded windows NT service application (vb.net 2003) that I
am working on (my first one), which reads a message queue and creates
multiple threads to perform the processing for long running reports. When
the processing is complete it uses crystal reports to load a template file,
populate it, and then export it to a PDF.
It works fine so far....

My first thought was to call
WorkerThread.Suspend
but the help cautions against this (for good reason) because the caller has
no control over where the thread actually stops, and it might have a lock
pending, for example.
I want to be able to stop a thread temporarily, and then optionally resume
it or stop it for good.

I have a class that writes data to the serial port and has a separate thread
to read data from the same port. Typically the main thread writes requests
to the serial port and then returns to the caller. The read thread waits for
a response while the application continues running. When a response is
received, I want to fire an event. But, I don't want the read thread to
raise the event because the event could spawn a whole set of new...

Hello All,
I am using VB2005 Beta 2 in VS 2005 and am running into a small
problem. I need to be able to add a picture box to the main form from
within a thread.
The program goes to a web site, performs a search based on POST
variables, retrieves the code, parses the information (including a url
for a thumbnail image) and displays the results.
I am using threads, since the program will appear to freeze while

This post is realy to get some opinions on the best way of getting fast
comunication between multiple applications. I have scowered the web for
imformation on this subject and have just found conflicting views and
far from ideal solutions.
My application has to send small amounts of data about 50bytes to
multiple client applications. The catch is that this has to happen
about 1000 times a second.

Hi everyone,
I have a Socket derived class that parses the received data into a message,
populates a object with that information and then tries to send an event to
inform the owner of the socket that there is message to be processed. But
this is not working as the socket receiver method seems to be in a different
thread then the form that owns the socket.
The receive callback gets the data from the socket and process the...

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...

Overview:
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. I'm particularly interested in Zigbee because I've heard it does some...

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...
