I have beaten my head against a wall long enough trying to get
dynamically loaded controls to fire events. Unless you have a complete
example that works, please don't spend lots of time responding to that
part of the post.
All my controls are static, I just need them to appear in the same web
form for other reasons. If I add all my controls to the web form at
design-time, I can then (instead of loading them dyanmically) turn...

Hello All,
I am developing a webform which creates ArrayLists of people's names and
addresses (the values are retrieved from an xml file) and dynamically drops a
user control onto the webform and populates it with the required names. Once
the user selects a name, the webform will then drop another user control (the
same control) onto itself and populate it with the selected name's addresses.
The user control is a combination of an...

Hello,
I created a user control that has a ListBox and a RadioButtonList (and other
stuff). The idea is that I put the user control on the ASPX page multiple
times and each user control will load with different data (locations,
departments, etc.).

I'm building a small web application - I started out placing all my code in
one file (config.aspx). As I continue to add code though it was becoming
very unwieldy.
After doing some searching online I found an article which suggested I might
place some of the code into web user controls. I created two new files
(general_info.ascx and store_front.ascx) and placed two chunks of code in
each.
I then registered the controls at the top of...

I'll describe the simplest situation of the problem.
I have a simple Web User Control which only contains a: <div id="bla"
runat="server" /.
I dynamically add it to a page, by performing:
SomeCtl ctl = new SomeCtl();
this.Controls.Add(ctl);
and of course apply a <% @ Register %tag in order to make SomeCtl known to

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...

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....

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...
