Just ramping up on JSON and JQuery and returning data to a ASP.NET web page from a web service using Ajax. The JQuery part is pretty straight-forward. However, when trying to return JSON formatted data instead of XML from a 2.0 web service, I'm stuck. The web service does have the System.Web.Script.Services.ScriptService attribute, so I can hit it via JavaScript; however, the web service always...always...returns data in XML format, no matter if I explicitly say I want JSON as the datatype in my JQuery code. So I don't know if this is an issue with the web service or the JQuery code. I posted this here, but realize that the category could be incorrect depending on where the issue is. Is there no way to return JSON data from a 2.0 web service? It's a production web service, so I can't change the code unfortunately.
View 3 RepliesI have a large web application that uses File.Exists() in a global file utility class flawlessy for several years now. I just built a new ASMX web service that calls that same method in our file utility class, and it returns False for the same exact file paths that are being passed in the web application. The paths are absolute system file paths, and they match on both the web service and the web app.I am confused... Why might this happen? The method I am talking about is only a few lines of code. A couple of lines simply validate the file id parameter being sent into the method. The last remaining line is this:
[Code]....
The previous line of code calls another method that uses a String.Format to insert the file id into the file path. That's it.
I have a web service that originally returned a string containing text formatted as XML. I was contacted by the programmer who is going to be consuming the web service, and he asked if I could make it "just XML" and not a string. I converted the web service so that it returns an XMLDocument object, and it seems to be returning data properly. I would just like to erify, however, that the XMLDocument object is what the other programmer was referring to when he said "just XML," and that the XMLDocument can be universally consumed by any programmer, regardless of his or her programming environment.

I have not any problem to receive the string from the SECOND function
However, When I call the FIRST one I receive an error:
"Microsoft VBScript runtime error (0x800A01C2) the wrong number of arguments or invalid property value argument"
I use this object: recXML = CreateObject("Msxml2.DOMDocument")
I have a web service that is declared like this.
[Code]....
Function inside the service simply returns string separated by some delimitor. This string is then used by JS function to assign to a jQuery datatable. Is there a maximum limit on size of this string? I have about 2000 rows with 6 columns each. I get an error (failed handle) when I return them all. But if I do only top 500, it works fine.Is there any size limitation?
[WebService(Namespace = "http://tempuri.org/")]
I have a webservice - called MyCompany.WebService1
I reference this using a web reference in my ASP.net web application.
Theres a method called "GetDeal" in this web service, that returns a "Deal" Object.
The deal object currently looks (for example) like this:
[code]....
This class is in a different assembly: MyCompany.Model
The web service references this assembly.
In my web app, I can call the GetDeal method. This returns Service1.Deal (service1 is just the name of the web reference)
I can access both properties above. I have now changed the Deal class, and added a couple more properties.
However, I can't see these new properties in my web application. I've updated the web service in the web application. I rebuilt the web service several times, tried removing the MyCompany.Model reference and re-addding it etc...
I can't figure out what has changed... This was working - I have changed the model before, and it's updated the reference correctly...
I have number of files stored in a folder.
I want to write a wcf service to ruturn a list of filenames based on the text typed in a text box.
The structure of the method i need is something like this :
[Code]....
The requirments is to return only the filenames that starts with the typed text. Only the file name part is required not the full path.
I have a webmethod that has three parameters:
public AuthenticationResult Authenticate(Enum type, string userName, string password) But the problem I had is that if a null/invalid enum is entered for the type variable it throws an error message.
So the obvious solution is to use a string/int instead but I am cannot do this as current users already use the existing webmethod.
So i was thinking:
public AuthenticationResult Authenticate(object type, string userName, string password) and handling the casting myself but the problem I had with this is that now my users do not have access to the Enum type.
So my question is can I publish the enum type without having it as a parameter/return value? Allow the client to access the Enum so they can pass it into the method. Would using a method that returned a type that was my enum work? Or is there a way to catch this custom error: (I dont think so as it appears to be on the client end when converting Enum to xml). The error is: (System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: Instance validation error: '45465' is not a valid value for Enum.)
In our project WCF service is acting as our BLL.
i had scenario where i had to fill list of object class without knowing its type see code:

we have console-hosted WCF Service and ASP.NET WEB Service (on IIS).
After some tough operation WCF Service must return some data(large data) to ASP.NET Web Service for next processing. I tested on small results - everything is ok.
But after testing on real data(serialized result object is near 4.5 mb) error occurs on ASP.NET Web Service (which is client in wcf-client-server communication).
Messages size are configured by next binding (on server and client):
NetTcpBinding netTcpBinding = new NetTcpBinding();
netTcpBinding.TransactionFlow = true;
netTcpBinding.SendTimeout = new TimeSpan(0, 4,0, 0);
netTcpBinding.Security.Mode = SecurityMode.None;

I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable.
EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.
I am coding a classic .asmx web service. The method get data (as a string) from a server, then assign data to an object, then return that object. But I want to cache that object to a XML file for other request. It's because the data from server is not frequently change. Thus, after some minutes, I have to refresh the XML file. When I refresh XML file, I could write object to XML first, then return that object, but that approach maybe slowly.
How can I return the object for client first, then write this to XML file?
What i need to do: When i click button on my .aspx page WCF service should be called, which should return data from ADO.NET entity data model. Entity data model and webservice is already added. I just have to write a method which will return data from data entity.
View 2 Repliesvs2010, .NET 4.0I have a webmethod which I want to return a data record (for example: name, surename, address, age, zip etc)I wonder how to accomplish this. I think the solution is about creating an object which contains all the records serialized. And then the webmethod returns this serialized object. I'm not 100% sure how to accomplish this, if some of you good provide me with some tips, tutorial or link to an article explaining it, that would be great

I´m new to web services and currently working with an integration to a third party system. I have created a web service that creates and exports a <List> of objects. The challange I have is that the third party company consuming my created web service wants to have the data as a XML document just as it is presented when I push the "Invoke button" when testing my web service on the server it resides on. Doing so I get all my exported data presented as a nice XML document. Since a web service actually exports this XML it should be a fairly simple task, but I do not know how? Would perhaps anyone have a code snippet consuming a web service and present the data just as an XML document? Or could point me to an example? I´m using VS 2008.

View 2 RepliesA 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 a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
