Hi,
I'm using the DataGridView in VB.NET 2.0. The DataSource is a Generic List
of a custom class0: lstMyPersonnes = New List(Of clsPersonne).
When I add a new clsPersonne to lstMyPersonnes, and rebind the
lstMyPersonnes to my DataGridView.dataSource, it shows the new record in
the DataGridView as it should be.
But when I click on a cell of that row, I suddenly got this error: "Index -1

Hi,
I am trying to dynamically install/deinstall a message handler to a
System.Windows.Forms.Form using NativeWindow.
I do not use IMessageFilter derived class because it intercept only the
PostMessage messages.
My problem is that when I install the message handler the second time a
"Fatal stack overflow error" occurs.

I have never seen WriteLine fail to produce a NewLine, at least, not until
now:
I was playing with an example given on pages 51-52 of the book "A Visual
Basic 6 Programmer's Toolkit".
The book is accompanied by files for that chapter in which an example uses
VB 6's Print to output to a Form..
When upgrading the code to VB .NET 2002, the upgrade wizard did not like
Print, so I replaced Print with Debug.Print in the VB 6 code.

I'm just learning C#. I'm writing a program (using Visual C# 2005 on
WinXP) to combine several files into one (HKSplit is a popular
freeware program that does this, but it requires all input and output
to be within one directory, and I want to be able to combine files
from different directories into another directory of my choice).
My program seems to work fine, but I'm wondering about this loop:
for (int i = 0; i < numFiles; i++)

Hi,
What is the right way to dispose of a NativeWindow? I guess the
NativeWindow is managed code and will be cleared by the GC, but the
window handle it is holding is a native handle!
I'm using the standard dispose code:

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. The idea...

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...
