WCF / ASMX :: Service Returning Old Values?
Sep 14, 2010I am developing an application with WCF services. The basic functionaloty of a screen is to provide an entry screen to add particular entity. Once save even fired It will save the data to the database and call the bind method to bind into the grid by refreshing the latest data.
When I am running the site from my source (Visual Studio) , it works perfectly. When the client calls method to fetch the data the WCF service, it returns latest (added) data. But the issue comes in the server when it works with IIS. I deployed the code in the server, once the data added I am getting the old data only. But after two refresh I am getting the latest data.
what required to be done to get the latest record.

WCF / ASMX :: Need Details On Returning An Entire Existing XML File From A Web Service?
Jan 20, 2011I've been reading quite a few tutorials on web services and xml files and one thing isn't quite clear to me. If I want to create an XML file on the fly the tutorials are pretty straight forward but, I want to grab an existing XML file from the web server and return the whole thing. Do I need to read the XML file and send each individual node or is there a way to send the file all at once? The tutorials imply that the whole file could be a node but I'm not clear on what that entails or if it would work. Also do you have a link to an example?
View 1 RepliesWCF / ASMX :: Windows Communication Foundation Service Returning Xml / Json Data?
Aug 25, 2010I Need by service contract to return the xml/json result depending on the request type. function which will convert my result set (i am using linq to sql) so that i do not need to create the xml format for the result set by iterating through the table row many times.What is the suitable way to do that.
I need a kind of short cut method which will convert the table data to xml result.Had i been using asp.net mvc i would have been able to generate the xml data by overriding the the ExecuteResult method in the ActionResult and giving Conetnt-Type = "text/xml" as OP.But since i am using Wcf i don't have the controller context(as controller context is the parameter that needs to be passed to Execute Result).
My present code for converting the table data to the xml format is below.
public XDocument UsersLists(string authToken)
{
bool IsAuthenticated = Authenticate(authToken);
XDocument xDoc = new XDocument();
XElement root = new XElement("Users");
[Code]....
I need to eliminate this way of generating xml for each table records.
C# - MVC - Blank Model Not Returning Blank Data
Jun 2, 2010I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action.
[HttpPost]
public ActionResult Manage(ProductOptionModel DataToAdd)
{
if (!ModelState.IsValid)
{
return View(DataToAdd);
}
var ProdServ = new ProductService();
if (DataToAdd.ID != 0)
{
//Edit Mode.
DataToAdd = ProdServ.EditProductOption(DataToAdd);
ViewData["Message"] = "Option Changes Made";
}else
{
//Add
DataToAdd = ProdServ.AddProductOption(DataToAdd);
ViewData["Message"] = "New Option Added";
}
var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID};
return View(RetModel);
}
So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. I have debugged the code and checked that the RetModel variable is empty.

View 2 RepliesADO.NET :: Returning A Blank DataRow?
Oct 19, 2010I have a method like
public DataRow
GetItem(ENTITY_TYPE
EntityType, long EntityID)
This fetches a row and returns it. Pretty simple.
However I can't test in the method to see if the row was fetched, as the method has to end with:
return ds.Tables[0].Rows[0];
If the row wasn't fetched, this errors as there is no row at position 0.
I can't do this:
DataRow dr;
if (ds.Tables[0].Rows.Count
== 1)
{
dr =
ds.Tables[0].Rows[0];
}
return dr;
.. because then I get an error that I can't return an uninitialised variable (dr).
I can't stipulate what the columns are and return a "blank" DataRow as far as I can see, because it's dynamic so I don't know what the columns will be. There doesn't seem to be a way to instantiate the DataRow return var except by assigning, er, a DataRow. Which I may not have.
I don't really want to switch to using the ItemArray and pass arrays about, I'd rather just pass the DataRow object as this is in a loop which might process a lot of rows.

WCF / ASMX :: Web Page Access Delphi Web Service?
Dec 14, 2010I 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.

WCF / ASMX :: Calling A Web Service On A Remote Server From A ASPX Page (website Project VS2005)?
Aug 30, 2010I 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?

WCF / ASMX :: Alternatives To Returning A DataTable From WCF
Dec 7, 2010I have read a lot of posts describing why it isn't good practice to return heavy objects like DataTable/DataSet to the client from WCF. However, there doesn't seem to be much discussion about the alternatives (or maybe I'm not looking in the right forums).
My problem is this: I've tried to convert my DataReader/DataTable into a List<List<string>>, where List<string> represents the data in each row, but get an error at the point when the data is being sent to the client. A simple List<T> or a one-dimensional array gets returned without any problems. But whenever I try to return a collection of collections, there seems to be an issue. I don't know until runtime what my DataReader would look like as different stored procs are called based on user selection from a web form.
What am I missing here. Is WCF not able to handle collection of collections (I know that multi-dimensional arrays are not supported)?

WCF / ASMX :: IIS Memory Increasing For Each Client Request In Asmx Web Service?
Nov 8, 2010A 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.
WCF / ASMX :: Returning A DataTable As List In WCF With WsHttpBinding

View 2 RepliesC# - WCF Service Not Returning Value To JQuery
Mar 10, 2010I have a problem with getting jquery to retrieve results from a WCF service. I am hosting the WCF service within IIS and when I attach the debugger to this process I can see that the code is processed successfully. However, when it hits the callback within jquery there is no data??
I have set up a trace on the wcf service and there are no errors. It just seems as though the data is lost after the wcf service method completes.
Here is the jquery code which calls the service:
$.get("http://ecopssvc:6970/ecopsService.svc/Echo", {echoThis: "please work"}, function(data) {
alert("Data Loaded: " + data);
});
Here is the wcf config:
<system.serviceModel>
<services>
<service name="EcopsWebServices.EcopsService" behaviorConfiguration="EcopsServiceBehaviours">
<endpoint address="" behaviorConfiguration="WebBehaviour"
binding="webHttpBinding" bindingConfiguration="" contract="EcopsWebServices.IEcopsServiceContract" />

Here is the service contract:
