Hi,
I am implementing a couple of webservices (all in the same web project)
that will access several backoffice systems to get and update different
types of information. All the methods in the several webservices return
a DataSet with the information requested.
All the methods of the Webservices also go through an initial phase of
checking either the Backoffice systems are online or not. If not, they
all return the SAME error DataSet.
To save lines of code (and the redundance of having the same code
repeated all over, with all the possible errors that can arise from
that), I am trying to do that check in the Application_Beg inRequest
event, but without success...
So, my question is: Is it possible to use the Application_Beg inRequest
event to catch the calls to all the methods of all the webservices, and
return a standard answer to the clients in case of error and not
continue the normal flow of the method called? If so, how can I achieve
that? If not, is there any other way?
I am at a loss...
Thank you in advance,
Ana Santana

Returning a special DataSet indicating an error will be prone to problems. A
consumer will some day fail to recognize it as an error and will try to do
something with it, and straightening things out after the fact will be
difficult.
In my opinion a better option would be to have a SoapExtension that checks
that the backoffice systems are OK, and if not, throw an exception. The best
place to do this would be in the ProcessMessage override, in
SoapMessageStag e.BeforeDeseria lize. If you decide that the backoffice
systems are not OK, throw an SoapException and the normal processing of the
request will be short-circuited at that point.

Sami

Hi,
I have a set of simple webservices calls that worked fine using .NET
Framework 1.0.
I am calling a Java/Apache based webservices, the calling side is not able
to supply a proper WSDL.
What it does is to call a webservice with two parameters, one being a
integer, the other one being a "String" which contains XML (not the best
practice, however that is the target interface and we cannot change that).

widely-accepted patterns and practices, but in this case, I find it

Hi guys
I've used an Application_BeginRequest function in my global.asax page to
implement some URL rewriting functionality on our website.
However, upon moving it to my host (1&1.co.uk), it no longer works. They
don't support Application_BeginRequest?
They've given me a list of the low-level functions they do support, which
can be viewed at http://s221042302.websitehome.co.uk/check.aspx

I've been playing around with the Global.asax file and learning how it can

will run "before" the page is loaded. It appears to work as I think and if I
place a Response.Write() method in it, it displays at the top...

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.
