PRB - ASP.NET "White Screen of Nothing" "Internet Explorer cannot display the webpage

Posted By:      Posted Date: April 14, 2011    Points: 0   Category :ASP.Net

PRB - ASP.NET "White Screen of Nothing" "Internet Explorer cannot display the webpage"

Please help,

We have a ASP.NET website that some times gets pages to lock up, with no content, all white screen, that eventually time out in IE to return an IE error page title "Internet Explorer cannot display the webpage". Note the spelling. We refer to this as the "White Screen of Nothing". 

Logs from IIS, show no errors (no 400+ status codes), and in fact, show the page that IE goes into the "White Screen of Nothing" for, as status code 200 in the IIS logs. Also, internal server-side ASP.NET tracing, show all code running as expected.

Trying to reproduce this error is difficult. It does not occur consistently. At best, if we open pages, close them, and repeat this as fast as we can, it will eventually happen on attempt to open a page and/or the refesh of a frame. It is not always the same page twice.

Some pages use AJAX controls. Most use GridViews. A few use Responce.Redirect. Nothing consistant.

Searches for causes of the "White Screen of Nothing" or the "Internet Explorer cannot display the webpage" are all over the place, and do not seem to be related.

We have managed to trap one instance of the "White Screen of Nothing" while in a Visual Studio 2008 debug session, where a weird, unknown thread was locked with the call

Silverlight gives the error "Internet Explorer cannot display the webpage"

Hello, I'm new to SharePoint 2010.  I have an SP2010 environment up and running.  When I click on a link that activates Silverlight, I get an error that reads "Internet Explorer cannot display the webpage".  The Server is on a different domain. When I use remote desktop to access the server, I can open up the same link using IE and I can see the content no problem. An example would be from the calendar page.  If I choose a date and select 'add', the browser fades and I see a 'loading' screen.  Then the next screen I get the error.  If I follow the same process on the server using remote desktop, everything works. What could the problem be?

"Internet Explorer cannot display the webpage" from IE7 - ASP.NET Development Server Error?

Dear everybody, I've just installed Microsoft Visual Studio 2008 on Windows Vista Ultimate. I created "New Web Site" and Started Debugging the page to see the blank page rendered. To my surprise, IE 7.0 displayed an error message saying: "Internet Explorer cannot display the webpage". I spent some time investigating and here is the result: The page going to be rendered assumes port 49791: http://localhost:49791/WebSite3/Default.aspx The ASP.NET Development Server operates under different port no: 49793 After changing the url above manually to use the port of ASP.NET Development Server, the webpage gets renderred correctly: http://localhost:49793/WebSite3/Default.aspx ASP.NET Development Server uses dynamic ports. I noticed that Debugging process always assumes port number lower by 2 than the real port number of the ASP.NET DevSer. Therefore Debug process never runs and displays the page. I do not want to manually edit the local host URL after every page rebuild, so my question is following: How to make the "Start Debugging" function to use appropriate port of the ASP.NET Development server? How to make Visual Studio to open the page being debugged? To mention couple of things I tried: I reinstalled Visual Studio2008, tried to disabled IPv6 as some threads recommen

Debugging - Internet Explorer cannot display the webpage



All of the sudden when I try to run an asp.net web app I've been working with, I get an "Internet Explorer cannot display the webpage" error when it tries to load the start page. I've tried changing the start page, changing the Development Server port, and setting a break point in page load (which never gets hit). Does anyone know what's causing this?

how to close underlying DbConnection without using "Using" statement


Here's my  code,  I am using "Data Access Application Block"  in ObjectDataSource's class file.

    public class Hospital
        private Database _db = EnterpriseLibraryContainer.Current.GetInstance<Database>("Conn");
        public SqlDataReader sDR;

        public SqlDataReader GetHospitals()

            RefCountingDataReader dr = (RefCountingDataReader)_db.ExecuteReader("GetHospitals");
            return (SqlDataReader)dr.InnerReader;

in my code, I didnt dispose the dataReader.  will it mess up my connection management ?  I want to make sure that DbConnection is properly closed.

I found this from "hands on lab".
"You are not doing any connection management here, but it is very important to Dispose the data reader returned. This is accomplished by the using statement in the code above. When the data reader is disposed, the underlying DbConnection is also closed."

please let me know if what I did is ok, i

DHTML and .NET: Host Secure, Lightweight Client-Side Controls in Microsoft Internet Explorer


In the past, Web developers often used ActiveX controls if they wanted customized client-side functionality incorporated into their Web applications. Now, they can build objects supported by the Microsoft .NET Framework which are more compact, lightweight, secure, and seamlessly integrated. By hosting .NET Windows Forms controls in Internet Explorer, developers can realize many of their client-side Web development goals. This article adapts ActiveX concepts for use with Windows Forms, and builds a multifile upload application that demonstrates these techniques.

Graphics: Manipulate Digital Images in Internet Explorer with the DirectX Transform SDK


The Microsoft DirectX Transform is a Microsoft DirectX media API that can be used to create animated effects as well as to create and edit digital images for Windows-based applications. Scripting and HTML can be used to display an existing transform on a Web page, and improved transform support in Microsoft Internet Explorer 5.5 makes it easy to use transforms. This article provides step-by-step instructions for writing a transform as an ATL project and shows an example of an image transform. C++ is used to instantiate, configure, and display transforms in this project.

Digital Dashboards: Web Parts Integrate with Internet Explorer and Outlook to Build Personal Portals


Digital dashboards gather information and functionalities from a wide variety of sources ranging from Web pages to applications such as Microsoft Outlook and SQL Server, and present the resulting information in a single user interface. Digital dashboards built with the Digital Dashboard Resource Kit (DDRK) are made up of distinct units called Web Parts. Web Parts, introduced with the DDRK 2.01, can contain any Web-based information, are reusable, and integrate with each other and with other dashboards. Creating Web Parts and getting them to work together is illustrated via a sample application that uses a PivotTable view. Integrating Web Parts with Outlook, the Outlook View control, storage, and debugging are also covered.
