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?

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 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 did a couple google searches about this and am not finding anything, so I thought I'd ask here. I'm working on our internal CMS and I noticed that we're getting live data back when doing debugging because of our web services instead of the dev data that I wanted. It doesn't do this on our dev CMS website, but we're trying to do all our development on localhost. Is there any way to set up an environment variable in our web config for the URL so that the CMS points to the dev database instead of live database that is referenced in the wsdl files?

View 3 RepliesWhen I open my ASP.NET site in IIS and try to open the .NET Trust Levels, I get an error message:
.NET Trust Levels There was an error while performing this operation.
Details:
Filename: ?C:inetpubwwwrootmyappweb.config
Line number: 445
Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"),or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
I've checked a few places, but I haven't found anything that seems like it would be locking that setting. Is there a systematic way of determining where that setting is locked?

I am running into a problem with a web.config in a child project that has the same connection string setting as a parent. We have this in several of our web apps but there is one case where we want a child not to use the parent web.config. Is there a setting or command in the child web.config to ignore the parent web.config?
View 4 RepliesEither I am blind with excitement or something is missing from VS2010. I have created a Silverlight 3 project and simply want to add a web reference (not service reference) to the project. I cannot see the 'Add Web Reference' anywhere.
I added it to the toolbar and it was disabled. I saw somewhere that I might need to change the target framework version but I cant see where to do that in the project properties either.
I'm currently trying to work out the best way to build this web application, which will then be intergrated on other systems, such as WinForms, Intranets etc.
We hope to include the usual layers i.e. DAL, BLL, BOL and UI but I have been experimenting with Entity Framework 4 and WCF Data Services and managed to get something in place where I was using WCF as a gateway to EF4.
i.e. Adding a Service Reference to my project and then using the EF4 context and writing LINQ queries against the DB
e.g.[Code]....
Now with the current setup I would still need to write a DAL Class Library, that interacts with the Data Service, because as I said WCF Data Services only seems to be a gateway, I can't see where to put the code (above) in the Data Service and then how I could these methods.
My questions are: 1. How do I develop a WCF Data Service in such a way to allow this behaviour - I know how I could do it using ASMX web service, something like [Code]....
2. If I am to use WCF Data Services, how is serialization handled (if at all) - again I know how to do something in ASMX web services
3. Again, If I am to use WCF, how do I add Security and only allow my applications to access the web service - for obvious reasons
4. Would it be possible / logical to also include the Business Logic Layer into the web service?
How to create an instance of web service without adding web service reference? How to identify the server address/name where the web service is hosted from C# code?
View 1 Replies<Application architecture>I'm developing ASP.NET Web Application by Visual Studio 2008.(.Net Framework Version = 2.0)I put followin two projetcs in the solution.a. Class library which implements all the buisiness logic for application.
(I'll call it "ClassLib" in the followin sentence)b. ASP.NET Web applicatoin which presents UI.(I'll call it "WebApp")ClassLib uses Web Service which located on other server. So, I set web reference in it. Method for url settings for this web reference is "Dynamic".
How do I add the WCF service built using VS2010 as a service reference to a Winforms app which is written in VB6?

View 2 RepliesI 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?
Using VS2008, I noticed that in Class Project I only have a choice of adding "service reference" where as in Web Application project, I have two choices "web reference" and "service reference".
I have used web reference. How is "service reference" different from web ref? and what's the major purpose of service ref?
Im 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
public IQueryable GetUsers()
{
return userService.GetAll()
).AsQueryable();
}
[code]...
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);
}

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 getting an error when i try to add a service reference of a WCF service. Error details is below. My web service is hosted on a different server and my client is on different server. When i run the service directly from IE i can see the service but adding it in .net web application i get error.

We have a chart on a page that current is hard coded with test data, client likes and we are trying to now link to live data.I have tried different things in the code behind to build the url and keep getting Null Reference Exception even though when i debug the url is there and complete. I can take the value that i get in debug and paste directly to the browser and the chart works. so i know that im building the url correctly, but setting the .Src of the image in the page_load event doesnt seem to be the correct way to populate the image..Here is the complete link that is built in the code behind that is passed to the src of the image control.http://chart.apis.google.com/chart?hs=300x265&chd=s:bD&chdl=DVDs|DVDs+with+Scracthes&chdlp=b&chl=44|5&chma=40,60,0,40&chtt=DVD+Report&cht=p3&chco=751010|FFCC33 In the page load event i have the following:
[Code]....
[Code]....
I place a break point on the line where i set the src and as i step thru everything is correct and the src is being populate with the correct link, but when i step past that line, then i get the null reference.Now why is it that i can paste that link to the browser and it works.. and if i hardcode that link in the image src on my aspx page and comment out the code behind it works there also..
we were all recently alerted by scottgu with this security vulnerability. [URL] I'm wondering, since I've been redirecting errors via Global.asax on the Application_Error event, I was wondering if that can suffice the fix for this issue or do I still need to place a setting on the web.config?
