I'm new to WCF web services never done anything with them before and I'm being asked to create a page to connect to a WCF web service
I have no idea where to start and I've searched the internet with no success.
Does anybody have an example of an asp.net page connecting to a WCF web service?
I've set up the WCF web service on my server but do not have a clue on how to actually connect or query it to get my XML data back.
The WCF web service is set up as it's own URL and only has 2 files within the root one being the web.config.
I somehow need to query this URL and get some XML data back from it.
Any ideas?
You need to create a service reference from your asp.net project to your WCF project. Right-click on the ASP.NET and click on "add service reference", set the URL of the service and VS will generate a proxy class for you.
Asking your favorite search engine for "asp.net add service reference" should give you a good selection of starting points.
Look into WCF connections and web.config. This link should provide you some direction: http://msdn.microsoft.com/en-us/library/bb332338.aspx#msdnwcfhc_topic5

We have an ASP.NET 2.0 site. A 3rd party has created a web service that we are supposed to connect to, and I was naively expecting a 2.0 style web service to be created. When I was given the url, I was expecting to see a .asmx suffix...but instead was given a url with .svc suffix.
Going to that page tells me to to create a WCF client by running svcutil...but, again, we aren't running .NET 3.0+ yet.
Since it's a web service, I'm thinking the basic functionality should be essentially the same, but freely admit I know essentially nothing about WCF (yet.)
Can I expect this to work eventually, or is there some kind of potentially blocking issue (WCF web services being inherently different in some profound way)? Is there a simple path for creating a basic client (like svcutil would if we were in the 3.0+ world)?
If it's using BasicHttpBinding (SOAP 1.1) it's probably interoperable.
In the "Add Service Reference" dialog in VS2010, click on "Advanced", then click on the "Add Web Reference" button.
I have several asp.net website projects for various sites.
Currently I want to add REST API's to these projects so I can start developing mobile apps (using HTML5/JavaScript/CSS3 and PhoneGap) that make use of these webservices.
Since WCF is far more powerful than regular asp.net webservices (among others with control over the service and authentication/authorization), I'd love to add these to my existing website project.
I did a Google search but cant find anywhere a step-by-step tutorial how this can be done. And also if there's any functionality I'd possibly loose when adding WCF functionality
I was also thinking of creating a new project specifically for WCF, but think I'd rather add it to an existing website project.
Can anyone help me with this?
Depending on exactly what your needs are and how your current web site is configured, there are two approaches.
If you are using a Web Site Project, then you should create your WCF service in a different application:
1) Create a new ASP.Net Web Application Project.
2) Add a new item to the project and select the type of WCF Service or WCF Data Service.
When you deploy this project, you will deploy it to your web server, but not as part of your web site since configuring the web.config will be a large manual effort.
If you are using a Web Application Project, then you could add the WCF Service directly to your existing project. However, I only recommend this approach if you are Silverlight applets within the web site that rely on the user's authenticated credentials.
WCF can be configured with a lot of bindings and it can be configured to return xml or json(.net 4.0). Try to create a wcf service configured to use basichttpbinding or wsHttpBinding and to format the response as json and use jquery to interact with the wcf service.

I have my own web service application with more then one .asmx file.
Now i am not getting how can i reference web service with my web application as "Add Web Reference".
I want to connect with both asmx files at once.
Means once i connect web service as add web reference and i can call both .asmx file from my code behind page.
Doesn't work that way. You have to reference each web service or consolidate them.
You could do this:
Invoking Web Service dynamically using HttpWebRequest
When you add a web reference to your application, Visual Studio creates a proxy class that you use to connect to the web service. You will not connect to the web service directly. The proxy class name is set when you add the reference. It suggests a name for you that you can change.
As long as you are using the proxy classes that are generated, you should be able to connect to as many web services as you desire.
I hope that helps.
I'm trying to consume a WSE enabled Web Service from an ASP.NET Web Site.
I've installed WSE 3.0, used the config tool to add WSE info to my web.config and then done an Add Web Reference.
I believe that the problem may be that this is a Web SITE, not a Web APPLICATION. As such, the proxy class is generated at runtime, perhaps not adding the WSE magic.
I can access the proxy class from metadata, and it's of type System.Web.Services.Protocols.SoapHttpClientProtocol, which as far as I can tell doesn't have any WSE functionality.
I realize that this is all old technology, but I don't get to decide what the servers run :(
Any help would be greatly appreciated
You are wrong, proxy is generated when you are adding web reference.
Could you tell me how you are adding web reference to the website.
Please refer following article - http://msdn.microsoft.com/en-us/library/5sds7a0b.aspx
After you have located a Web service
for your application to access by
using the Add Web Reference dialog
box, clicking the Add Reference
button will instruct Visual Studio to
download the service description to
the local machine and then generate a
proxy class for the chosen Web
service. The proxy class will
contain methods for calling each
exposed Web service method both
synchronously and asynchronously. This
class is contained in the local .wsdl
file's code-behind file. For more
information, see Web References in
Visual Studio and Add Web Reference
Dialog Box.

How to retrieve data from database using Web services on VB?
Does it have to be a web service? Have you considered WCF? (Windows Communication Foundation)
http://msdn.microsoft.com/en-us/netframework/aa663324.aspx
If I understand you correctly, you are asking how to setup a web service using vb.net to communicate with the database and return the results.
If that is correct, then there are 2 parts:
How to write a web service
How to communicate with a database
Here are three pages that will help you create a web service:
vbdotnetheaven
codeguru
techrepublic
As for the database, if you are talking about SQL Server, then see this page here and this page here
Your question isn't clear enough. Are you trying to access a web service run by ASP.NET using VB? If yes, you can make SOAP request to your web service easily using VB, your web service will then fetch the data from database and return to you. You can have a look at this tutorial on how to make a SOAP request using VB -

Hope that helps.
Create a proxy class from the web service's WSDL, using Visual Studio's "Add Web Reference" feature
Configure the proxy, such as for security, if needed (the details depend on the API)
Call the proxy from your code
