There is a event that is called when the call is complete. Wait until the event is fired before proceedding.

Example (check out the LoginCompleted event):

ServiceReferenceMyApp.ServiceWebClient client = new ServiceReferenceMyAPp.ServiceWebClient();

client.LoginAsync(UserEmail.Text, UserPassword.Password);

client.LoginCompleted += new EventHandler<ServiceReferenceMyApp.LoginCompletedEventArgs>(client_LoginCompleted);

void client_LoginCompleted(object sender, ServiceReferenceFlair.LoginCompletedEventArgs e)

{

...

}

Hi Mike, thanks for the tip. Definitely helped out this newbie Silverlight developer. I'm struggling to grasp why it's async only though. If I have something dependent on the data coming back, how can I get my data out of the completed function? It's hard to work around when the completed function does not have a return type and you can't pass in additional arguments.

I'm hoping I'm just missing something.

thanks.

Figure out the result (for VB). Use the AddHandler expression first then the .HelloWorldCompleted will show.

AddHandler client.HelloWorldCompleted, AddressOf client_HelloWorldCompleted

client.HelloWorldAsync

Private Sub client_HelloWorldCompleted(ByVal sender As Object, ByVal e As HelloWorldCompletedEventArgs)

'Do something here

End Sub

I'm able to call the .HelloWorldAsync method, but the .HelloWorldCompleted method is not shown in the intellisense and an error ocurrs when calling it.

Mike,

I got the result now.The mistake I did was that i created a ASP.Net Web Application project instead of Web Site.

Did you put the web service in your web site and not your SL app?

Also, when clicking "Discover" for Add Service Reference did it find the web service?

Make certain you are using the full namespace when declaring the HelloWord.

Thanks.

Hi Mike,

Thanks a lots for this article.I just did exactly what you have done here.But I'm not able to make a call to the HelloWorld() method after creating the client proxy.I'm not getting the intellisense for the HelloWorld method after the client proxy.Can you please let me know the solution.By the way both service and the client are in the same machine.Thank you.

What error do you get?

I am not certain but you may need the clientacccesspolicy file to be present:

<?xml version="1.0" encoding="utf-8" ?>

<access-policy>

<cross-domain-access>

<allow-from>

</allow-from>

<grant-to>

<socket-resource port="4502-4534" protocol="tcp"/>

</grant-to>

</policy>

</cross-domain-access>

</access-policy>

Hi Mike. I have a question.

Ive created the Web service and it's working in the IDE just great. But when I publish this to IIS, Im having problems.

So, here is what Ive done.

I created a project and created my WebService within that structure.

Then, I build a User control in a 2nd project within the same solution. Its an Ad Rotator user control and retrieves images from an Sql Database. This will be used on the other projects in the solution. Obviously, it uses the web service that Ive created to get the images.

The project has several pages, so I created these in separate projects in this solution. I navigate to pages on a button press. The web service serves images to the Ad rotator, and other things on other pages.

With this setup on IIS, the Ad Rotator is not retreiving images and my navigation doesnt work. It all works in the IDE.

So, I thought you may have a suggeston.

Thanks
