I am new to Silverlight. In Silverlight, we can get data from server using ASP.Net (using WebClient and HTTPWebRequest classes in Silverlight) and using WCF Service.
Assuming that I do not need the cross domain capability, what is a good option in terms of Security and ease of development?
I am trying to call a service from a silverlight application, but I am getting the following error.
Uncaught Error: Unhandled Error in Silverlight Application An exception occurred during the operation, making the result invalid. Check InnerException for exception details.
This works fine locally. I don't know if it make any sense, but locally if I add the url of the webservice on a browser, I am getting the details page of the service. In the other hand, on production server, it prompts me to download it.
public MainPage() {
InitializeComponent();
Loaded += new System.Windows.RoutedEventHandler(MainPage_Loaded);
}
[Code]....
I have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
I'm calling a silverlight component in my aspx page like this
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<div id="silverlightControlHost" > [code]...
I would like to modify my page aspx so it takes the parameter itself. Today I'm calling the page
Config.aspx and I would like to do something like this call it
Config.aspx?ConfiguredCarId=11
How do I modify the above code to reflect the change?
I have the following code for consuming a service that is not working for me. what I can do to narrow down whats going wrong?
The address is: http://localhost:57667/ExampleService.svc/
When visiting directly I get the 'You have created a service... message'
The code that goes wrong is here. It causes the following error:
_url = "http://localhost:57667/ExampleService.svc";
TextReader textReader = new StringReader(HttpPostClient.Post(new Uri(_url), bodyData.ToString(), _exampleServiceRequestEncoding, Properties.Settings.Default.HttpPostClientExampleAvailabilityTimeout));
ERROR MESSAGE:When visiting this URL directly: http://localhost:57667/ExampleService.svc/ProcessRequest
The exception message is 'No component for key example.ExternalWebServiceStubs.Example.ExampleService was found'.

I'm pretty new to Silverlight/RIA/Asp.Net thing, and I'm trying to figure if an Asp.Net website is required (for hosting the app) if I wish to use RIA services with Silverlight?
View 2 RepliesIm using silverlight ria services and trying to called a domain service methodthe domain service class signature goes like this public class UserDomainService : DomainServiceand I have a simple operation to return data

I have a Silverlight control that is hosted within an ASP.NET application. The Silverlight control has a web service reference. The URL of this service is going to vary when we install the application for our customers. I need a way to be able to change this web service reference URL from within the web.config of the ASP.NET application. How can I do this?

this compiles fine an a silverlight proxy is generated on the silverlight client side. how ever when makeing calls from silverlight eg
LoadOperation op = UserDomainContext.Load(UserDomainContext.GetUsers(),UserLoadedCallback,null);
int i = op.Entities.Count();
it is always 0, the domain servcice method is never hit when i put a breakpoint.
I am in the process of implementing jQuery calling WCF service which is hosted in the same domain. My application uses Win Auth that works fine with ASP.NET app. I would like to know from the team if the user calls the WCF service from the ASP.NET what is the security context in which the service runs? Or it uses the web.config security which is specified? Are there any links related to this where i can get some information.

I have a simple wcf service developed in vs2010
[ServiceContract]
public interface IService1

public class Service1 : IService1
{
public string GetData(int value)

the following call is working
protected void Button1_Click(object sender, EventArgs e)
{
ServiceReference1.Service1Client p = new ServiceReference1.Service1Client();
Label1.Text= p.GetData(5);
}
but when I am trying to call it from jquery its not working
$(".test").live("click", function () {

I am developing application for PDA. The Sql Server compact edition is installed on PDA. The data is stored on PDA's DB as well as the Server Database through wifi.
If the server is available,the data will be stored through web service, If not available ,the data should be inserted when the server is connected to the data.
which is better to transfer data whether the web service or windows service?
If web service means, how could i transfer the data to server database?
I have almost the same problem as you have described in [URL] service. I have a asp.net webservice that calls a WCF service. On my development machine this is working fine. But if i deploy my ASP.net Webservice it is not working. Both the ASP Webservice en WCF service needs my cridentials. How did you solved your problem. In the logging of the WCF service I see that my credentials is not passing to WCF.
View 1 Repliesthere ( my first post in this forum ). i created a web service which searches for user info from a adatabase
based on the user id(input). i want to call this service from the bookstore web site i created for my course project but apparently i'm not doing something right. i get an error : [IndexOutOfRangeException: Index was outside the bounds of the array]. So to give you an idea of exactly what i've done so far, here's the code...
First for the web sevice: using System;
I have a simple ASP .NET web service running and I want call it from a php client. I m using nusoap soap client.
The following is the client side php code:
<?php
require_once('lib/nusoap.php');
$wsdl="http://localhost:64226/Service1.asmx?wsdl";
$client=new soapclient($wsdl, 'wsdl');
$param=array('number1'=>'2', 'number2'=>'3');
echo $client->call('add',$param);
?>
The web methods I have created in web service are as follows:
namespace WebService3
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
public class Service1 : System.Web.Services.WebService
{.........
However when I run the above php code it does not return the added value of the passed parameters. Instead it previews the word 'Arrays' I m not experienced in php programming. Am I doing something wrong the above codes?
I've got a website which contains the profile of users. I am now working on a mobile app and I would like to access the profile details from via the app. My idea is to simply create a webservice which returns the relevant fields (some of which might be password protected). How can I ensure that the web service is being request only by my application and not by anything else (desktop, other app etc..)? Initial idea was to have a secret key embedded in the program which is used to encrypt the data sent over to the web service, but I'm not sure how difficult it would be for someone to find that key since it's on the client side app.
View 1 RepliesI have a web service I'm converting it to wcf
I want to create a couple methods in the wcf... these will call methods in the web service
but I don't want to use soap or whatever because it is so slow
So I made a WCF service inside my web project.
Then I new up the web service and call a method...
Is it using soap? Is this just the same as calling any other method in the code? Just as fast?
I'm trying to insert a new EF object containing a reference to a related table via foreign key, and cannot get the reference stored in the new object. I have two tables in a SQL Server 2008 Database:
Component Templates
PartGroups
with a Foreign Key linking them thus: ComponentTemplates:ID [0..1<->*] PartGroups:ComponentTemplateID
I have imported these tables into a .NET web application project .edmx file (using a new ADO.NET Entity Data Model), and then created a Data Service which I then reference in a Silverlight 3.0 project. The objects are available as expected in the data context called by my Silverlight app and load correctly. Now, when I try to save a reference of ComponentTemplate into a newly created PartGroup, the PartGroup object is created in the database, but the value of ComponentTemplateID in the newly created table record is NULL.
[Code]....
(Note that _ctCtrl.ComponentTemplate is a confirmed non-NULL object reference to the parent object on which PartGroup is a child)
I am trying to interface a website we have with our helpdesk software. The helpdesk software has a REST API that i can connect to. So far I have been successful in getting a current ticket with the following code.
[Code]....
[URL] How would I implement this in ASP.Net? I want to create the ticket, and need to be able to retrieve the access key that it returns. I tried using the same code above, but instead changing the method string to this.
Code:
method = "request.create&tNote=Testing method&sFirstName=Jose"
But I get a "Bad Request" error from it.

AJAX Toolkit 20229.20185
I have an AJAX auto complete extender that calls a web service to generate a string[] for a textbox. Works great, The issue I am having is that I set the OnClientItemSelected property of the auto complete extender to call a JavaScript function that will intern call another web service to get the remaining data I need based on the item that was selected. (I need this because the auto complete web service only allows for key/value pairs and I need to return 10 columns of data) I cannot get the JS function to call the web service. I keep getting "(Namespace) is undefined" as a JS error. I tried to impliment Microsoft's example located at: [URL] but even if I copy there code line for line in a new project, I still encounter the same error.
Samples.AspNet.WebService.Add(a, b,SucceededCallback); //'Samples' is undefined - runtime If I remove the namespace so that it reads: Add(a, b,SucceededCallback); //Endless loop until you get stack overflow error
Has anyone got MS C# example to work? I saw a lot of people had this line missing in the web service, but I already had it. [System.Web.Script.Services.ScriptService]
I am trying to call a webservice, written in PHP from ASP.Net. I have added Web Reference using "Add Web Reference". The url is: http://mikikard.com/public/webservice?wsdl
In Add Web Reference Window, I can see the list of functions. But, When I try to build the Website, It gives the following Error:
Unable to import binding 'SoaptestBinding' from namespace 'http://mikikard.com/public/webservice'.
In my asp.net application, I am using wcf service to get all the business logic. I am using that service reference in my application to work with that. Now adding that service reference is giving another option Update service reference is giving Generate asynchronous operations. If I check the option and add the service will it generate asynchronous methods for my existing service. If so how do I use the metohd.
