I'm using the BeginInvoke method of a delegate to invoke
a thread asynchronously and then use the EndInvoke to
retrieve the value. This works wonderfully until a
Serviced Component is added to the mix. When the
Serviced Component is invoked with BeginInvoke, the code
hangs for the duration of the call rather than running
async. Any ideas? Sample code below:
Private Sub Button2_Click(ByVal sender As
System.Object, ByVal e As...

I have implemented an asyncrhonous execution of a method using the

I am trying to spin multiple worker threads in a thread pool.
Here is the code:

Hello -
I am trying to write a class that has an async BeginX and EndX, plus the
regular X syncronous method. Delegates seemed like the way to go,
however, I still am having problems getting exactly what I want. Here are
my goals
1. I would like the IAsyncResult that is returned by the Begin function to
be able to be waited on or polled to check for completion.
2. The Begin function would take a callback, and the async process would

Hi,
I encountered a problem trying to write a code that does the following:
1. Main GUI thread invokes a delegate using BeginInvoke.
2. A secondery thread (from the application's managed thread pool)
starts executing and BeginInvoke returns.
3. Main GUI thread remains responsive while the secondery thread
executes in the background.
4. Secondery thread finishes its execution.
5. Main GUI thread is notified of the completion of the...

Greetings!
First, I'm not 100% sure where to post this question. I use VB.NET for
this project, but it's really a design question (a question on which
method to use when solving this problem).
In this medium sized (30 or so forms) application, our users have
requested a more visual notification of when the client (this app) is
communicating with the server, or for other lenghty processes.
Disabling the current form and changing the...

I need to create a webpage that asynchronously loads a series of user
controls onto a page.
If the user control take longer than X seconds to load it should
display an error message in it place. The rest of the page should
continue to load whilst the seperate user control threads are loading.
What is the correct way of doing this?
I've created a delegate for loading the user control sand called

Is it possible to asynchronously call a method from worker thread so that
this method would execute in main-thread? I'm doing some work in worker
thread and would like to report progress to main thread to update some
controls. But I'd like to do that asynchronously so that worker thread would
not block until main thread finished updating and refreshing controls which
take some time. Using invoke is out since it blocks worker thread until...

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:

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....

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...
