Hi danjal;

I looked at your solution and it seems that you're using IEntityLoginManager. You have to use AspAuthenticatingLoginManager instead since you're using ASP.NET.

Hi smi-mark,

 

Do I have to do something special to use ASP.NET authentication with DevForce? A setting or something?

 

Thanks for helping.

Are you using asp.net authentication with DevForce? If so, the context sample should definitely work. I'll take a look at your sample project later, but it should work.

Hi,

 

I have made a little sample project where I try to get the logged in user thru the HttpContext – but it is empty .

 

I read the documentation from Ideablade on this issue, but I am missing something. Can someone look at the sample and help me?

 

1.       The sample application takes a username and password. These are passed into the LoginAsync method of the entitymanager. (MainPage.xaml.cs)

 

2.       These are then transferred to the Login method of a loginmanager that implements the IEntityLoginManager. (LoginManager.cs)

3.       The loginmanager validates the username and password against a database.

 

4.       When this process is done and successful, the user can load a collection to the pivotviewer. (ViewImageLibrary.xaml.cs)

 

5.       When doing this a http request is sent to the server where some httphelpers handle the request. (CxmlHandler.ProcessRequest in HttpHandlers.cs)

6.       The problem here is that the HttpContext.User is empty.

 

7.       Then the collection is created and sent back to the PivotViewer. (RNImageCollection.cs)

 

In my webconfig I have set these settings:

....

<serverSettings loginManagerRequired="true" />

....

<serverSettings useAspNetSecurityServices="true" />

....

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

....

<authentication mode="Forms" />

....

Hi danjal;

I've read that previous thread and if I understand correctly, you want to handle a request that comes in using your custom HttpHandler.

Using smi-mark's sample, we can now do this inside the ProcessRequest method.

    public void ProcessRequest(HttpContext context) {
      context.Response.ContentType = "text/plain";
      context.Response.Write("Logged in as: ");
      context.Response.Write(context.User.Identity.Name);

     if (!AuthenticateUser(context.User)) {
        throw new Exception("No access!");
     }

     //Else you can query
      var mgr = new EntityManager();
      var query = new EntityQuery<Customer>();
      query.QueryStrategy = new QueryStrategy(FetchStrategy.DataSourceOnly, MergeStrategy.OverwriteChanges);
      try {
        var images = mgr.ExecuteQuery<Customer>(query);
        var count = images.Count();
      } catch (Exception e) {
        var msg = e.Message;
      }
    }

Because we use a login manager, and it does not allow us to run this code:

 

var m_entityManager = new C2NetDomainModelEntityManager();

 

var query = new EntityQuery<EntImage>();

query.QueryStrategy = new QueryStrategy(FetchStrategy.DataSourceOnly, MergeStrategy.OverwriteChanges);

 

var images = m_entityManager.ExecuteQuery<EntImage>(query);

 

It worked before the upgrade, with help from the the DefaultManager.

Hi danjal;

Could you elaborate on why you need to pass the DefaultManager to create another EntityManager?

Hi,

 

We upgraded our DevForce to 6.0.9 Silverlight.

With the new version we encounter a show stopper – EntityManager.DefaultManger is going to be obsolete.

 

We use a PivotViewer control in our application that use a collection that is generated server-side by some HttpHelpers. We have been discussing this before on this thread:

http://www.ideablade.com/forum/forum_posts.asp?TID=2525&KW=defaultmanager&PID=10054&title=entitymanager-server-side#10054

 

When querying for data we use this code to get an EntityManager:

var m_entityManager = new C2NetDomainModelEntityManager(EntityManager.DefaultManager);

 

But this code does not work anymore.

 

What is the right way to use DevForce when working with a control like PivotViewer (dynamically generating a collection with HttpHelpers)?
