When I am trying to invoke a method using a proxy class i get error
"System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.NullReferenceException: Object reference not set to an instance of an object. at ..."
I have made web service, when it is accessed by remote computer to send me the data using this web service then the following errors shows on the remote computer:-
"Server was unable to process request..A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
I am trying to call a webservice and i am receiving the following error
Server was unable to process request -- > object reference not set to an instance of object .
Steps done for calling the webservice
1) created a wrapper class using wsdl.exe tool
syntax :- wsdl.exe /l:vb <url.asmx?wsdl>
<url.asmx?wsdl> is the url of the webservice to be called.
2) Imports <webservicenamespace>
[Code]....
3) while checking the trace Its occuring while invoking the webservice function
object[] results = this.Invoke(<webservicefunction(parameters)>)
I have a .Net Webservice(2.0 framework) and I am trying to call this service from SQL
server 2005 using CLR.
I have created assamblies on server and trying to call the we service through CLR, but I'm getting below error:
"Exception:
Server was unable to process request. ---> Invalid URI: The URI is empty."
I'm getting an exception when trying to access an .asmx webservice within a MVC site. I've tried numerous things like updating the web reference within the console application and building another quick app to test, but can't get passed this issue. If I pull the URL out of the svc variable, I can browse to it directly.

The exception was coming out of the Web Service itself. There were some global variables not being initialized directly through the .asmx call that were being initialized by the application itself.
Some simple checks on variables within the Web Service and setting what needs to be set have fixed up the issue.
I have a webservice, it has few webmethods. when i create a client proxy and invoke the methods to check its response, i am getting this error. Can someone tell me what things can i check to know the cause of this? The error is not saying much hence blocked on this.
View 1 RepliesI have created a web service that interacts with my DAL. It has the usual kind of methods, create, retrieve, update and delete. I have published this web service to our live Windows Server and I can see the web serice URL. The web service works on a few method calls but does not work specifically for one object. I am getting the following error: Fault Exception was unhandled by user code. "Server was unable to process request. ---> Data is Null. This method or property cannot be called on Null values."
To summarise: Web service is live, I can see it in my browser. Some method calls work. One specific one does not. I have verified that the method works (it is just calling a SQL stored proc that does return data).
When i try to execute the code below i get the error "unable to connect to remote server".
The internet connection is set and if i copy and paste the serviceurl directly on the browser it works.
public string GeoCode(string address)
{
if (String.IsNullOrEmpty(address)) throw new ArgumentNullException("address");
string ServiceUrl = "http://maps.google.com/maps/geo?output=xml&q={0}&key={1}&oe=utf8";
string url = String.Format(ServiceUrl, HttpUtility.UrlEncode(address), MyApiKey);
System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url);
request.Method = "GET";
using (System.Net.WebResponse response = request.GetResponse())
{
return response.ToString();
}
}
I am developing the web site, It consists of device name list and related Build Button. When one click the Build button the one process will run in server. When more than ten user click the Build button more processes will create at that server will hang. How can send all request from client to single process in server.
View 2 RepliesI have a stored procedure which fetches data after joining 8-9 tables and inserts that into a temp table. It was running fine till now, but now when the amount of data fetched have exceeded 20000, the SP is breaking. I have debugged the sp and found that this main query is failing after returning arround 15000-16000 records.
The error message says Transaction (Process ID) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. I know what is deadlock, but when i checked with SP_LOCK stored proc i only found that my process is running on database only. So how is this getting deadlocked when there are no other processes running simultaneously on server.
I was wondering if it is possible to call a webservice or send a SOAP request using a provided certificate to encrypt my password (my identity) and use another to encrypt/sign a timestamp, service header, & soap body? Does anyone have any material or sample code where I can test encryption and security too? It doesn't have to be my own certificates, I just want to see it work and then I can possibly tailor it to my needs. After the SOAP request, there will be a provided response which I assume I will have to decrypt.
I found this thread, but it doesn't seem to use signatures or an SSL connection. Does VS 2010 have some extra features to help out on this? I believe the SOAP should look like this.
<soap:Envelope>
<soap:Header>
<svchdr:ServiceHeader>
<svchdr:StaticRegion>...</svchdr:StaticRegion>
<svchdr:DynamicRegion>...</svchdr:DynamicRegion>

Have not run the ASP.NET Development Server for a while. Today I copied a production website to my workstation and ran it with VS 2008. The following error message popped up. What is the problem with the ASP.NET development Server on my workstation? The website on the Production server still ran okay.Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same. If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of KEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesaspnet_stateParametersAllowRemoteConnection.
If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '127.0.0.1' as the server name.
Unable to start debugging on the web server. The IIS worker process for the launched URL is not currently running.I'm running Windows 7 64 bit, VS 2008 sp1.When I first try to debug I get the error msg above. I wait a few minutes (presumably some service is starting) and debugging will start but no breakpoints are recognized.Some of the things I've tried:Changing the binding of my site from a static IP to "*".

I have a web service hosted on a web server, I invoke the web service using jquery ajax.
The service returns results successfully when invoked locally from the server, but it fails when invoked from a remote client machine (not in the same domain).
I see the request fail in the firebug returning error (401 UnAuthorized) and the response has the following error (Request format is unrecognized for URL unexpectedly ending in '/List').

I m having a database problem that I couldnt identify. The IIS loses connection to database once in 3 weeks. Once you restart the IIS everything is normal. Looks like IIS is fine because i can go to static pages. When I go to a page that requires database connection I get this error:
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - Either the application has not called WSAStartup, or WSAStartup failed.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Is this a connection string problem?. because without changing anything if I restart the webserver all is fine. Is this a problem with application state?
I am new to ASP.NET but what i am trying to do is create a webservice (in C#) with a method that basically returns the IIS HTTP 202 Error Code (ACCEPTED) page.Is there any method that would automatically return this? Or would i need to write some sort of code that would cause the error message 202 to display?

View 3 RepliesI have an asp.net mvc application that spawns a Process as follows:
Process p = new Process();
p.EnableRaisingEvents = true;
p.Exited += new EventHandler(p_Exited);
p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath;
p.StartInfo.WorkingDirectory = dir;
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "pdflatex.exe";
p.StartInfo.LoadUserProfile = true;
p.Start();
p.WaitForExit();
Before going further, I need to know whether, e.g., pdflatex.exe is a managed code or a native code? Edit 1 I need to consider this because: (Hopely I am not wrong...) Each Asp.net application runs in an separate/isolated AppDomain as opposed to a separate/isolated process. A native executable cannot live in an AppDomain.to be continued.. Shortly speaking, I hope my site does not spawn a new process for each request. Because a process is more expensive than an application domain. Edit 2 My asp.net mvc application allows users to submit LaTeX input commands such as $ax^2+bx+c=0$ to be converted to a pdf file rendering an quadratic equation. Behind the scene, this web app will spawn a process executing pdflatex.exe. The job of pdflatex.exe is converting the LaTeX input commands to pdf document.
Currently we are developing an ASMX, ASP 2.0, IIS 7 web service that does some calculations (and return a dynamically generated document) and will take approx. 60 seconds to run.Since whe have a big machine with multiple cores and lots of RAM, I expected that IIS tries its best to route the requests that arrive in its requests queue to all available threads of the app pool's thread pool.But we experience quiet the opposite:When we issue requests to the ASMX web service URL from multiple different clients, the IIS seems to serially process these requests. I.e. request 1 arrives, is being processed, then request 2 is being processed, then request 3, etc

I have seen a few posts regarding this issue but not one specific to my problem and I have no ideas as to what I need to do to debug this.I have some combo boxes on an aspx pages, when I select a value from the first one, it fills the second with value and so on with the third and fourth. This works with no problems until I wrap an asp.net UpdatePanel around the combo boxes and try to "ajaxify" the whole process so the page isn't dancing around. The exact error I get is: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 404

Can any one explain me indatil the situation how db process the request.?
