Displaying Modal Dialog in a Thread

have a 3rd party .Net dll that wraps a set of further unmanaged dll's. The ..Net DLL basically uses pinvoke to wrap the calls. The low level dlls provide an API to talk to a complex device which appears as a USB hub (with a scanner, flash drive and some other bits and pieces). Using a VB.Net windows app, we call the main unmanaged API function (lets call it doStuff() ) and then call messagebox.show to pop up a modal results dialog. This...

OK this has me perplexed, puzzled and bamboozled! I have a remoting service which I displayed a message box in. I then wondered what would happen if a client made a call to the service while the message box was being displayed. Since the call comes in on a different thread the client call was not blocked. This seemed to make sense to me. Next I thought, what will happen when the client calls into the server if I try to use a delegate...

Hi, I have a periodic problem which I am having a real time trying to sort. Background: An MDI VB app with a DB on SQL 2000. I have wrapped all the DB access into an object which spawns a thread to access the database and then displays a modal dialog which allows the user to cancel the task, if it is taking longer than they want, and shows them a display of how long the query has been running so far.

I'm following the example from the MSDN library on how to create modal dialog boxes in C#, but something isn't working properly. If I create a modal dialog box and show it using ShowDialog(), the main form behind the dialog box is still enabled and can operate normally. If I use MessageBox.Show() to show a message box, the main form is disabled until the dialog box terminates. How can I make a custom dialog box do this?

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...

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.

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.

But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
