I'm trying to figure out the webservices architecture for library that
we currently use as a monolithic component.
Every execution is expressed by a call like this one
public static IList executeIt(someA rguments)...
To be completed teh executeIt method can take up to 15 seconds, so I
need to use asynchronous calls.
I read how .NET 2.0 manages async webservices very well, throught the
class System.Componen tModel.AsyncCom pletedEventArgs (as explained here http://66.249.93.104/search?q=cache:...l=en&client=ig
-sorry for the use of google cache but weblogs.asp.net seems to be
down right now)
Now I'm trying to find out how the service should be created in order
to have just one flow of execution at a time. I mean if the service
receives two calls, there must be some kind of check to assure the
execution of the second call begins after the first one's ended.
How can I do that? Could you tell me some good links?
Thanks a lot

Lorenzo,
Why would you want to allow only one instance of execution for your web
service? Also, I would suggest reevaluating how you are designing your web
services. RPC-like calls are not really the desired way of doing business
for web services. They are really more about document exchange and business
processes, IMHO. Services exchange documents (in XML) which are processed
and affect some change in states (perhaps) in a database, or produce some
outcome. That is my view on them. I am not an expert though.
That being said, maybe you have no control over the web service design, so
that may not help you. With respect to your original question, I would offer
that you could create one main web service which is the entry point to your
system. This service would queue requests into a message queue (perhaps
MSMQ). Another service would then, one at a time, service the queued
requests. This second service could be written as a Windows Service to run
24/7 in the background. It would read from the queue, process, then repeat.
Hope that helps.

Hi All,
I'm trying to work out how to close the connection to the browser at a
defined point within my code, but go on to do some time-consuming
processing with PHP.
Although it *should* be possible to do this by moving the slow stuff into a
function registered with register_shutdown_function, it appears that in
many cases, the connection is not closed before calling the shutdown
function - there are also issues with calling other...

I know why the following doesn't work ... I can't figure out how to make it

fibonacci numbers to run for approx 5 seconds. The timer fires, the
exception is raised, but it is not caught ... because the execution stack
for the function that raises isn't in the same thread as the try: except:.
How do you fix this? Is it better to do this without exceptions as...

Hi, I have an app that writes text messages into a pipe and reads it out.
Other programs write into this pipe too. Sometimes the pipe is full and
my app freezes if it wants to write in that moment. It is not an option
for me to open the pipe with O_NONBLOCK, so I thought I could
use threads. Always when something shall be written into the pipe a new
thread is created. These threads may hang on os.write, but they'll write out
the data ASAP....

This is backwards of what I usually want--normally if you have a
long-running ASP script, it's a good idea to check to see whether the client
is still connected so you can cancel execution.
However, I have a script that absolutely MUST finish one it's been
started--is there a way to cause the entire script to execute, even if the
client disconnects in the middle of the process? It doesn't matter if the
script returns anything to the...

is it possible to implement some safe way of performing two or more
instructions in a kind of "atomic" way?
consider this: we have two queues (implemented on top of an List<T>).
now we need to move an element from one queue to another, so we need to
do something like this:
queue2.Enqueue(queue1.Dequeue());
int this case we may assume that nothing can cause this to fail
resulting in loss of the object we want to move.
