I am going to be receiving data in a web service. After I receive this data I will be mapping it to a data transfer object. I want to be able to catch exceptions if the data from the service is missing any of the required values, times out or any data is malformed.
What can I do to generally catch these exceptions?

My problem is I have handled timeout error in client of WCF error in such a way that if data is large to fetch, after 10 minutes(as all timeout in web config of client are set to 10 minutes) it should show me customize message 'Too many records to fetch, please modify criteria'. It works on my local system as per expected but if I put it in test server(Service is in one test server and Client application in one test server) it gives me following runtime error.
The message could not be processed. This is most likely because the action [URL] is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding. The thing is if I set SendTimeout in test server client config less than 20 seconds then it works fine but we should not be limited upto 20 seconds as it is awfully short.

New to web services, and while developing my first project, after some hours of googling, I can not find how can I change the charset used in the web service XML ouptut result. Using Visual Web Developer 2008 Express, I developed the web service, and also a VB program for communicating with the service. This web service will simply send a string of alfanumeric characters. Because of the real final use of this web service, I want to be able that the web service could send the XML encapsulated response in plain characters, without the HTML conversion. That is, I need to receive "&" instead of "&" and "<" instead of "<" Is this possible, and how can I do it?

I inherited a old WSE 3.0 service. I am building an ASP.NET client for it. It is returning a MTOM response so my client is complaining. Does anyone know of a way to change the response type to XML? Or change my client to accept MTOM? I just want this crap to work.

On my page I have a dropdown for country.
On my asmx service I want to get the value of the dropdownlist to filter the next input which will be state/providence.
My code on the asmx:
[Code]....
I want to add another clause to the WHERE statement to restrict Country = @Country so I will need to get that value to the web service.

A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.

I have spent a couple of days on this one. I have an ASP.NET website that has Linkbuttons on
the Default.aspx page.. I added a WebService to the Website because later on the WebService will
subscribe to a Provider(Feed) of News, Sports and Weather and things like that. So when a Linkbutton
on the Default.aspx page is clicked it will connect to the link in the WebService which will load the News,
Sports or Weather onto the Default.aspx web page.
The problem is I can't get the LinkButton to execute the Link in the WebService. The link will call the page up
to where you see all of the Web References. But then if you want to execute one of those references you
have to click its link and the Invoke button that will follow. My questioh is how can the link on my Default.aspx
page execute the link in the WebService. Now I changed the LinkButton into an <a href> but I still can't execute
the link in the WebServices. I always use www.Microsoft.com as the link when testing and I wasn't sure about the return type
so I put "void" for an HTTPRequest, so below is the link from the Default.aspx web page and below that is he asmx file:

lately I'm using less and less the ASP.NET controls and also turns off the viewstate in almost any page, in my opinion its easier to maintain your pages, you get more control over what happening and most importantly it gives a serious performance boost to large pages (no view state). I'm also using a lot of ajax in my projects (without the script manager / updatecontrol but via javascript) is anyone here working like this? is this bad practice ?

Code:
public static void Test()
{
try
{
OpenConnectionToDatabase(); //Opens a connection to Oracle DB
} catch(Exception e)
{
e.Data.Add("Query:", command.CommandText);
throw e;
}
}
When this code is executed when the Database server is being shutdown and the communication is disrupted, .NET throws the following error: Item has already been added. Key in dictionary: 'Query:' Key being added: 'Query:' at System.Collections.ListDictionaryInternal.Add(Object key, Object value) How can this be?

I'm wondering what's the preferred way to manage exceptions in an MVP implemented with a Passive View.
There's a discussion in my company about putting try/catch blocks in the presenter or only in the view.
In my opinion the logical top level caller is the presenter (even if the actual one is the view).
Moreover I can test the presenter and not the view. This is the reason why I prefer to define a method in the view interface:

We are using renderaction provided by MVC futures. We've noticed that HttpExceptions in child action methods are not propagated to the parent action. Even though a fragment has failed, we still see the parent request resulting in a 200, and this throws our error handling for a toss.

I have a weird situation here. Using VS2010 and the MVC2 application template, I'm trying to set up error handling, but it refuses to work... Even with a simple controller throwing an exception in the index:
[Code]....
And <customErrors mode ="On"></customErrors> in the web.config file, MVC breaks into the code and tells me that "Exception was unhandled by user code". The default Error.aspx (static text only) is located in /Views/Shared, and I've even removed the login partial view from the master page.
