I have a lot of respect for David Fenton and Allen Browne, but I don't
understand why people who know how to write code to completely replace
a front end do not write something that will automate the code that
implements managing unbound controls on forms given the superior
performance of unbound controls in a client/server environment. I can
easily understand a newbie using bound controls or someone with a
tight deadline. I guess I need...

I have implemented a container class with IList and bound it to a listbox.
Works just fine, but if i then add a new item to my list, the listbox is not
updated.
Looking at the definition for IList it is clear that it does not have any
events to tell the bound controlls about changes, but can it really be that
after adding to the list I allways have to call an update method for the
listbox? I would rather have designed the interface to...

I've been doing a simple for-each loop to remove multiple selected

The problem is that this code doesn't work because its modifying the

I have a data bound listbox that I want to select multiple lines then
process each line.
I bound a two column datatable to the listbox and set the DisplayMember
property to the appropriate column of the datatable. I set the
SelectionMode property to MultiExtended.
I am able to load and select multiple lines in the listbox but I can not
figure out how to retrieve both columns for each line selected in the
listbox. I know that there is...

Hi all,
I have a listbox that is complex bound by an arraylist. The problem is that
when I delete an object from the arraylist, the listbox does not reflect
those changes. I tried refreshing the listbox with no luck and, because it
is already bound, I can't just delete the item directly from the listbox
without an error (because it already has a datasource, you are not allowed
to delete/add anything to the listbox directly).
The...

Hi. I have a form with a listbox and a few label fields all bound to a
dataset. When i navigate the listbox the labels change accordingly. so far
everything works good.
I made a button to delete a record. I delete the row from the datatable and
update the database with the adapter and that all works good. The record is
removed from the listbox.
Here is my problem.

I have been trying to figure out for days on how to read values from a Bound
ListBox. The listBox gets the values from an Access Table.
I can read values fine for Non-Bound ListBoxes, But the same code doesn't
work for Bound, see below:
Any one of these work for a non-bound listbox.

I am fairly new to VB.NET and I am having some difficulty working with a
bound listbox.
On a simple form, I open a connection to my database and load a dataser. I
then bind a listbox to the the dataset and set the display member. I also
connect some filed using databinding.
I am able to choose an item from the listbox and edit it, but the listbox is
not refreshing (only the original values are visible in the listbox). If I
choose a...

I'm very new to the whole programming thing and I'm having a little trouble with the syntax of my code.
My code contains a bound listbox where the display member and value member are two different values. I want my program to cycle through the listbox and compare the value member of each item in the list box with a fixed value. My problem is I can't seem to find the syntax to grab the value of the item in the list box. I can't use...

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,...

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....

In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules.
He will explain when you may want to use classes instead of User Defined Types (UDT). For example, to manage the data in unbound forms.

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...
