I'm coming to asp.net with mainly a desktop application background, and
would be grateful if someone could explain what is meant by "unload" in
asp.net . It's not the same as unload in a desktop application context. What
kinds of things are typically done in various unload eventhandlers (page
unload, form unload)?
Thanks

Every request into the webserver creates a new page object to handle that
one request. There are various events that fire on the page on each request
(Page_Init, Page_Load, etc). Page_Unload happens to be done of them. It's
meant to be a place to clean up any resources that you've not yet cleaned
up for the request. Typically, though, you probabaly should have already
cleaned up any resources by the time you get here (so in PageLoad, for example,
you typically open the DB connection, use it, then close it immediaetly).
So in the 4 years I've been doing ASP.NET development, I can't ever recall
using Page_Unload.

Hello,
I've an application where all my pages implement a PAGE_CODE string
property, this property is stored in HttpContext.Current.Items.
In some page, I must persist data in session while the user perform
operation on this page (postback navigation based). I also need to
clean up the session data when the user leave the page (by a anyway).
My question is about the Unload event, is it safe to use the unload

Hi All,
In an ASP.NET project I am trying to improve performance. As it is now there
seems to be a huge bottleneck between the end of the Page.PreRender event
and the beginning of the Page.Unload event. Using a performance analyzing
tool (AqTime 4.9) I am not able to find out what is happening between these
2 events. Can anyone shine some light on what is normally going on between
these 2 events?
Thanks in advance.

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.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
