WCF / ASMX :: Max Return Size Of String From Web Service?
Feb 14, 2011
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?

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 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")

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.)

I have a requirement to build a simple ASP.NET web page which sends some parameters to a web service, and then displays the string which was returned. I'm a complete .NET newby and the only examples I can find seem really really complex. I just need something mega simple, but which an handle parameters being sent to the web service. Can anyone point me in the direction of a simple bit of C# which will do this with no frills or fuss?

How do you secure a WCF web service when you are using the traditional "connection string in the web.config"?
I have added a WCF service to an application which uses a JQuery post and returns JSON. The request happens on the client side. The purpose of this service is to return search information while the person is typing text into a textbox.
It works well, but there is a problem because the application will be used by a number of people and I am maintaining a role based security within the applications MS SQL database. The connection string to the database is in the web.config file.
In order to run the JQuery call to the web service the user must have at least read access directly to the database. I want to allow the application to control the access, but removing all security to the WCF service opens the application up for external access by unauthorized users.

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()

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'm using return url to restore a users site position after a session times out. This works fine. However if the user happens to have a popup open when a session times out, it returns the user to the popup screen (correctly) but the popup now takes up the entire screen. Is there a way to return the popup in it's original size or another way to check for popups, perhaps using the sitemap?

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;

Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?

My WCF Client calls my WCF Service which then calls ASMX Web Service. The problem is i have configured my wcf client and wcf service to windows credentials type but when wcf service calls asmx service the user credentials (default windowsidentity) is not passed to asmx service.
In WCF Service i am able to get user identity by using : Thread.CurrentPrincipal.Identity.Name;
WCF Service - i have disabled anonymous access and enabled windows authentication. ASMX Web Service - i have disabled anonymous access and enabled windows authentication.
