WCF / ASMX :: How To Return XML Structure From A Web Service In Page
Mar 24, 2011
I have a problem to connect my ASP page with a Web Service.
I'm going to explain the situation:
VB: WEB SERVICE: service1.asmx.vb (http://localhost:1234/Service1.asmx)
[Code]....
FROM ASP page
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")

Whats the best way to return a tabular structure from an ASP.NET (2.0) web service?
It should be inter-operable with Java, Iphone App or any other platform.
EDIT: By inter-operable I mean the other technology/client should be able to consume it or deserialize it to their native types, instead of parsing response XML.

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 am new to web service... I have created a simple web service to add a record to sql server by passing a parameter and returns true or false once done. It the same time, I want to return the customer_account_number value created on the sql server.. so basically I want to return the true and false and one (or more) additional values.

<LastName>Wilson</LastName>
</Person>
</People>

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?

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.

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 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:
Added contract
[OperationContract]
dynamic GetReferenceTableData(string tableName);
method in service:
public dynamic GetReferenceTableData(string tableName)
{
try
{
dynamic tableData = ReferenceTableDAL.GetReferenceTableData(tableName);
return tableData;
}
catch (Exception ex)
{
throw;
}
}
method at DAL(ReferenceTableDAL):
public static dynamic GetReferenceTableData(string tableName)
{
Database db = DatabaseFactory.CreateDatabase(Flags.ConnectionStringKey);
DbCommand dbCommand = db.GetStoredProcCommand("USP_GETTABLEDATA");
dynamic objDynamic = null;
if (tableName.ToLower() == "a")
{
objDynamic = new List<A>();
}
else if (tableName.ToLower() == "b")
{
objDynamic = new List<B>();
}
else if (tableName.ToLower() == "c")
{
objDynamic = new List<C>();
}
try
{
db.DiscoverParameters(dbCommand);
dbCommand.Parameters["IN_TABLENAME"].Value = tableName;
DataSet dsTableData = db.ExecuteDataSet(dbCommand);
if (tableName.ToLower() == "a")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((A)dataRow);
}
}
else if (tableName.ToLower() == "b")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((B)dataRow);
}
}
else if (tableName.ToLower() == "c")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((C)dataRow);
}
}
}
catch (Exception ex)
{
throw;
}
return objDynamic;
}
@ Aspx
try
{
using (DataServiceRef.DataServiceClient petService = new DataServiceRef.DataServiceClient())
{
dynamic tableData = petService.GetReferenceTableData(tableName);
//tableData is null ,exception
}
}
catch (Exception ex)
{
throw;
}
There is no exception at dal or service end when i debug list gets filled ok but when returns to aspx error at aspx(no exception gets caught at @ service) but exception at aspx i.e:
Message:The underlying connection was closed: The connection was closed unexpectedly.
Stack Trace: at System.Net.HttpWebRequest.GetResponse()

I'm having a very hard time wrapping my head around this problem (it might be the heat from the summer finally arriving).
Problem:
I want the user to press a button client side which performs javascript data preparing and at last send a JSON structure to (currently a asmx webservice on) the server. The JSON structure is several levels deep.
Server side I create a PDF file which I want to send back to the user.
Goal:
The user feeling is that she presses a button and expects a PDF to return to her - either in a new window or as a download (preferrable).
Tools:
The system consists of (client side) HTML, JavaScript and ExtJS and (server side) ASP.NET.
Normally I would use an ashx handler to return a file to the client, but can I send a JSON structure to the handler and still be able to parse it correctly server side?
I am searching for the pattern to use.

I have site that I need to have a vendor send an Http Post to us, using querystring parameters, then I have to look up some data and return a few results and parameters back to them. Can this be done using CLASSIC ASP? I ask this because I am still in a learning phase with .NET and have limited resources available to set up a web service.

I have created a dynamic web page . It gets loaded using a file keys.txt. This file holds the keys which are used to display a web page like panels order, text of labels , number of buttons and so on..It is consuming a web service written in delphi. All works fine but when 2 users try to access this service simultaneously then a error is displayed (Internal Server Error 500) "Access violation at address 0040404C in module "accelerate_gateway.dll". Read of address 00000000"Accelerate gateway is the name of delphi web service.It seems to me the problem of multi threading in delphi service ??But I have not done any multi threading in client asp.net page as well. ??It simply creates web service object and access its methods.As I am using a file contents to load a page, so I am concerned if it can create trouble as well ?? . Although I have used FileShare.ReadWrite in it.

i have designed a web service which would create 2 csv files on the system. I want to send the links to the location of the files as an url attachment over the aspx page.
like : http://myserver/download.aspx?file1=C: empimage1.png&file2=C: empimage2.png
the output from the asmx web service is : [Code]....
where xx.xx.xxx.xxx is the ipaddress. this is the whole output i get from the webservice.
how do i get the aspx page to send the attachment in the format i mentioned above? I have added an asp website to the project and added the webservice as a web reference to this but i do not know how to get the location from the xml output file of the webservice result.

I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder. When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.
The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for the new web service i'm trying to call. Have I missed any steps?

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.

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;
