Since ASP.NET 2.0, asynchronous web service client can be implemented
with event-based pattern, instead of original BeginXXX/EndXXX pattern.
However, I didn't find any material about event-based server side
asynchronous web service. So, we can only implement asynchronous
webmethod with BeginXXX/EndXXX pattern, right?
I don't why ASP.NET 2.0 don't provide event-based server side pattern.

Do you mean allowing the server to push information to the client?
You can't because web services are 1 way.
Or do you mean asynchronous processing on the server side? You don't really
need to because IIS will process each request in it's own thread context.
You only need to spawn additional thread if you have multiple tasks to
complete.

No, i don't mean allow the server to callback client, but let
asynchronous operation in server side.
That is, IIS arrange one thread to initialize operation of incoming
request, but the thread has no need to escort the whole processing of
the request. Because WebService may involves I/O operation,
synchronous web method will make the thread block on I/O. This is not
good, since by default there is 25 worker threads per CPU.

Though worker thread number in TheadPool can be configured, it is not
suggested.
Better way is to make I/O operation performed in I/O thread in
asynchronous way.

Since ASP.NET 2.0, client side has event-based pattern, but I don't
know why server-side is still using IAsyncResult(Be ginXXX/EndXXX)
pattern. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

IE implements its standard down-up model: any mouse event goes from the
deepest visible element to the top. By carefully studying fromElement
and toElement properties, one can handle events on any point of their
way up.
NN/FF implements a "Russian hills" style: mouse events go first

My unstanding of all VB up to and including vb6 is that an event could
not "interrupt" itself.
For instance if you had a timer event containing a msgbox then you would
only get one message.
However in vb.net you get continual messages (even setting the system
modal property).
Firstly, are these two assumptions right and if so what is the approved

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

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,...
