I'm new to ASP.NET and have run across a problem several times while
working on web apps. I often need to create content dynamically (based
on an event) which contains dynamically created linkbuttons (or other
webcontrols). These linkbuttons have to be created after events are
processed, and so these linkbuttons cannot have handlers added to them
because they are too late in the page lifecycle for the handlers to
register.
An example:

Hi,
Is there documentation that talks about the page lifecycle, the lifecycle of
controls on the page, and the rendering of inline code, in a single
document?
Thanks,

Inside of a Page class, how do I capture the Request object values
before the Page_Load event is called of that Page? I have a situation
where I have many server controls on a Page that get created in the
constructor of my Page, but I need them to know about some info that
get's set via the Page_Load from the Request (and even Session for
that matter)
thanks!

Hi,
I have a webform which has several server controls attached. The entire
form is data bound to custom objects. The collection objects are cached
using the Cache object. In my use case, I have to update my database,
synchronize my cached collection and refresh my UI. After my database
update I call dropdownlist1.databind() and my items are exactly the same
when they should be less 1 item. If I understand the "control execution...

I have a user control into which I insert a bunch of controls dynamically. I
have it all working just fine - Everything is there on Postback, etc.
I load this user control into a hosting ASPX page at runtime during the
Page_Load event procedure of the hosting ASPX page.
Question: Would it be better to load the user control from the hosting
page's OnInit event rather than Page_Load? Does it matter or not?
I ask because I understand...

Hi,
In a windows.forms application I would BeginInvoke a delegate on the UI
thread to collect data from a database. When the call returns to the
AsyncCallback, if the Control.InvokeRequired = True, I would then have the
Control.BeginInvoke(New AsyncCallback(AddressOf GetDataCallback), New
Object() {ar}).
How would one achieve the same thing on an asp.net page (without using a
webseervice)? In the code below, because the...

Hello All,
I have a question which is pertinent to Page's lifecycle.
I declared a protected static object (global variable within that class)
whose value is set only once when the page is loaded. Will that object's
value be accessible
during consequent postbacks or is it set to null after HTML is rendered
initially?

Hi,
Is it possible to have programmatic access to the Page object in
Application_BeginRequest, or is it too early in the lifecycle...?
E.g. to be able to change a page's MasterPage dynamically, something like:
protected void Application_BeginRequest(Object sender, EventArgs e)
{
if (Session == "True")

I have a page that inherits from a base page that is currently
overriding all of the On* events. For the most part I'm accomplishing
everything I set out to do with the inheritance, but I wanted to get a
little more information to lock down what I think I know and also to
answer a couple little questions.
Given a base page, and the page inheriting it, as I understand it, the
page lifecycle flows like this:

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
