I have a control called UniqueTextBox, that implements the
IPostBackDataHandler.
I have trying to use the control in a composite control called
UniqueTextBoxEx.
The LoadPostData method of the UniqueTextBox is never getting called.
What do I have to do to have child controls process their own postdata?

I am getting a curious problem where LoadPostData is not being called after
registering the control using RegisterRequiresPostback. Other controls not
requiring postback registration are having LoadPostData called. Each
control calling RegisterRequiresPostback does have a uniqueid and exists for
the lifetime of the page, so it's not a mis-referencing problem.
It's worth noting that this was working fine until I killed the Viewstate
and...

I have a custom control (MyTextBox - taken from Microsoft website)
that implements the IPostBackDataHandler interface. It is added to
the controls collection of a placeholder control during the Page Load
of a main ASPX page. Now if we debug the MyTextBox, we find the order
of events like so (during a Posback, of course): OnInit -> OnLoad ->
LoadPostData.
My question is why does the LoadPostData occur *after* the OnLoad
instead of...

I have a page that contains a number of link buttons that are used for
making selections. I load my LinkButtons during the Page_PreInit event and
they render fine but then I need to make a change to one of these
LinkButtons depending on the selection.
I am using the Command Event and passing a key in the Command.Name field.
From within this even handler, I am clearing my LinkButtons and then
re-redering and marking with a different...

Hello there. My question is related to full custom server controls.
1) The 'input' element that caused the postback already has 'Me.UniqueID' in its name field. I assumed, the value of postDataKey is this UniqueID is that right?
2) How do you set (and retain) the values of the different properties across postback. For example i have some String properties (eg. SelectedItemNo, ImageUrl...), integers that i want to save according to which...

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...

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...
