I want to know if the PostBack concept applies to HTML web-based forms,
regardless of what programming technologies we use: For example, ASP,
ASP.NET, Java, CGI, etc...
PostBack means to send the HTML form to the web server? Since most of the
time I heard this term in ASP.NET circle, thats why I raise this question.
Please advise. Thanks!

often has the following happened to you and how have you dealt with
it.
I am consulting on a new project. Originally I was going to get data
dumped to me from an external system, and import the needed data once
a week into a normalized design that I had created. I knew what my

I created simple ASP.NET web application to test how AutoPostBack property
in a web control works.
I set AutoPostBack property to be true of a web control. When I run the
application, here's the sequences when I step through the program:
1. Page loaded to the browser
2. Page_Load method is called with non-postback event
3. The user has certain actions on a control
4. Page_Load method is called with postback event

This is an old problem,, but I never had it so bad like this before,,
the events are refiring when clicking the Browser refresh button.
In the Submit button in my webform, I capture the server side click
event and I update session information to track the visibilty of some
panels in a wizard type navigation ("Next >>" and "<< Back" buttons)..
but the refresh button makes another event firing and takes the whole
thing to a Choes..

I have a user control being used instead of a frame page. when the user
clicks on a menu item I need to send the ID (integer value) of that menu as
a parameter in the postback of the user control which will be used to query
sql server to repopulate the datagrid in the user control.
I also wrapped the user control in a panel element so I could position it on
the page.
I'm clueless on how to get started with this.

Hello
Can anyone tell me what is the best way to persist a complex object across postbacks in ASP.NET
eg
* I have a Person class with methods to edit the person's info
* I navigate to my ASP.NET page "person_edit.aspx?PersonID=5321
* On Page_Load...If Not IsPostback I instantiate the object based on the Request("PersonID")
* I bind form fields to the properties of the object
* I execute 1 or more subs to edit the person's info

I've been googling for some time, and could not find the solution to
this problem.
I am testing the paging feature of gridview. I have a very simple web
form on which the user can select a few fields to be included in the
table, which is to be bound to the gridview.
The web form looks like so (Don't worry about the stupidity of this
web form for now.):

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:

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,...
