control. I am trying to catch a keydown event in this class and then
supress it from the rest of the control as well as the form that hosts
the control. The problem I am running into is that the form that hosts
the control will respond to the keydown event event.
Any ideas what I am missing?
Some source code to help:

I have a Datagrid that is inside a panel. I want to use the keyDown event to
reconize the arrow keys. But I have no luck at all. The problem is that the
keydown event won't fire at all, unless I click on a row (withs will turn
blue then) and then click on it again . Now if I press any key the event will
fire (except for the arrow keys).
I also tried to override the IsInputKey => no luck.
I also tried to override the ProcessCmdKey => With...

Ok,
I have tried to do this with the System.Web.UI and can't find anything
for the webform. It seems much easier for a Winform.
Any help in trapping Webform keydown event and keyup event is
appreciated.
Thanks,
Trint

I am struggling to get the keydown event for checkboxes to work when pressing
down arrow and enter. The so-called help talks about overriding the
IsInputKey method for the controls, but doesn't give an example. How do I
override a control's method?
TIA

I have a form with several combo boxes in the header used to determine the records that will be displayed on the form. When I tab or enter from the last combo box in the header, I want the focus to move to the first control on the form. When I Shift+tab from the first control on the form, I want the focus to move to the last control in the header. The form is a continuous form.
The first control on the form is either a text box or a combo...

My dg is loaded (from stored procedure) and has 1 record in it. When I
press enter on that row it does nothing (I have a breakpoint just inside the
code where i check for enter pressed)
if (e.KeyData == Keys.Enter)
It never goes into that event.
For the DataGridView I have:

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

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...

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...
