StackOverflowException was unhandled when passing in DataContract class

Hello,

I have a class who is used by Silverlight though RIA Services and who contains the [DataContract] and on its properties [DataMember].

That class is also used by my WPF Application and i have a List<myClass> which i want to bind it on ListBox.

The problem is when i bind the list, when i select an item in my listbox, the first item is always selected and the right-click doesn't work properly.

In fact, the behavior of UI is weird and badly refreshed.

But, before, the class didn't have DataContract/DataMember attributes and it worked fine.

Do you know, a workaround to continue to use that class and avoid to create an other class specially for databind ?

Regards,

Guillaume.

i have .net 4.0 application in wpf . application is running fine but when i close the application by using exit button. it throws the exception after stopping the debugging. the exception is  "An unhandled exception of type 'System.StackOverflowException' occurred in WindowsBase.dll ".

the code in exit button is

 private void btnExit_Click(object sender, RoutedEventArgs e)
        {
            this.DisconnectReaders();
            Environment.Exit(0);
        }

don't know from where it throws the exception and why ??

Hi,

For a class like following,

[Serializable]
 public class SampleClass 
 {
  public String Name { get; set; }
 }

and a class Library containing following void method which simply assigns some value to the property.

public void AssignValueToClass(SampleClass classInstance)<br/>{
 classInstance.Name = "Name assigned to Class";
}

When I call above method through Remoting client like following

RemotingClient client = MyRemoteObject.GetClient();
SampleClass instance = new SampleClas();
client.AssignValueToClass(instance);
MessageBox.Show(instance.Name); -- No Value is assigned to the class, Value of Name remains Null and message box shows empty.

But when I simply add a reference to my class library, and simple create the instance of the cl

I usually work with windows forms, and am just starting to work with ASP.Net, so appologies if this is a dumb question!

I have a master page which has a search button on it. The results of this are built up using a Linq statement and if there are any results, I want to display the results in a contents page.

On the masterpage, I have the following code:

Private _res

    Public Overridable ReadOnly Property SearchRes()
        Get
            Return _res
        End Get
    End Property

 Private Sub DoSearch()
   'some code to get a linq result
   'then

    If res.Any Then
            _res = res
            Server.Transfer("SearchResults.aspx", True)
        Else
            'no results
            LabelNoRes.Visible = True
        End If
 End Sub

On the SearchResults.aspx page I have this code.

Dim m As pxSite = CType(Page.Master, MasterPage)
        If m.SearchRes IsNot Nothing Then
            Label1.Text = "Results found = " & m.SearchRes.Count
        End If

m.searchRes is always nothing. 

What am I doing wrong here?

Thanks

I've tried setting the <pages pageBaseType="DynamicWebPage" /> value in web.config, but when I response.write out the page type, I'm still getting Microsoft.WebPages.WebPage.

I'm simply trying to sub-class WebPage and add some additional functionality such as a dynamic PageData dictionary similar to Phil Haack's dynamic ViewData dictionary.

Thanks,

Hi! Friends..

how to pass the value from one page to another page in asp.net  with out Using State Management Concepts?

Like 1. cookies

        2.Session

        3. QueryStrings

     With out using the above should pass the values...

I know what Singleton Pattern means and Abstract class means.

What I wanted to know was how would this apply to real world.

Could anyone give me any good example or simple explanation.

Say I have a simple website, why would I use any of the above if any.

Why would it simplify my architechture.

Thanks in advace. 

Hello All,

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.

Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.

After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)

Code is as follows.

    Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest
        Try
            Dim requestedUrl As String
            Dim targetUrl As String
            Dim urlLength As Integer
            'Save settings which will be used while redirecting to appropriate page
            requestedUrl = context.Request.RawUrl
            If requestedUrl.IndexOf("?") >= 0 Then
                targetUrl = requestedUrl.Substring(0, requestedUrl.IndexOf("?"))
            Else
                targetUrl = requestedUrl
            End If
            If targetUrl = Nothing Or targetUrl.Length = 0 Then
                targetUrl = requestedUrl
            End If
            urlLengt

Hi,

I hope this is the right place to ask this question.

I'm trying to make a control class library. I want to have a GenericHandler as a WebResource so I could call it from the web project that will use that control.

I need this handler will get parameters from the query string and return JSON data acourding to what it get in the QS.

I know how to create JS and images WebResources, so I tried the same on a generic handler I added to the class library project but all it does is return the source of the handler file and not the result.

Is what I'm trying to do possible? If so, what should I do?

Thank :-)

Hi,

I wrote a class to pull adinfo and for the life of me I can't seem to figure

out why it says "Invalid Login Name" no matter what I type in. If I leave

it blank it seems to work properly but it doesn't seem to be actually searching

the AD. I'll drop the whole class here, it's being initiated by a button click

on an outside form.

Thanks in Advance for any help Offered,
