  • Data-Virtualization problem with SurfaceScrollViewer

    - by TWith2Sugars
    I'm in a situation where I'm using an ItemsControl with a SurfaceScrollViewer bound to an AsyncVirtualizingCollection and all of the data is being requested. I'm aware that it's due to the ItemsControl request all of the data but I'm not sure how to get around this. I've tried the AsyncVirtualizingCollection bound to a ListBox and it works fine and I'm now attempting to having it bound to a SurfaceListBox but the problem persists. Any ideas of how to overcome this? Thanks & Regards Tony

  • why including www in a jquery load causes it to fail?

    - by zenna
    Could someone enlighten me as to why including www in a ajax request causes it to fail. i.e. This works: $('#mydiv').load('http://mydomain.com/getitems'); But this doesn't (returns nothing) $('#mydiv').load('http://www.mydomain.com/getitems'); Note that www.mydomain.com/getitems is a valid domain, in the sense that if I point my web browser to it I am able to load the page.

  • What Amazon S3 .NET Library is most useful and efficient?

    - by Geo
    There are two main open source .net Amazon S3 libraries. Three Sharp LitS3 I am currently using LitS3 in our MVC demo project, but there is some criticism about it. Has anyone here used both libraries so they can give an objective point of view. Below some sample calls using LitS3: On demo controller: private S3Service s3 = new S3Service() { AccessKeyID = "Thekey", SecretAccessKey = "testing" }; public ActionResult Index() { ViewData["Message"] = "Welcome to ASP.NET MVC!"; return View("Index",s3.GetAllBuckets()); } On demo view: <% foreach (var item in Model) { %> <p> <%= Html.Encode(item.Name) %> </p> <% } %> EDIT 1: Since I have to keep moving and there is no clear indication of what library is more effective and kept more up to date, I have implemented a repository pattern with an interface that will allow me to change library if I need to in the future. Below is a section of the S3Repository that I have created and will let me change libraries in case I need to: using LitS3; namespace S3Helper.Models { public class S3Repository : IS3Repository { private S3Service _repository; #region IS3Repository Members public IQueryable<Bucket> FindAllBuckets() { return _repository.GetAllBuckets().AsQueryable(); } public IQueryable<ListEntry> FindAllObjects(string BucketName) { return _repository.ListAllObjects(BucketName).AsQueryable(); } #endregion If you have any information about this question please let me know in a comment, and I will get back and edit the question. EDIT 2: Since this question is not getting attention, I integrated both libraries in my web app to see the differences in design, I know this is probably a waist of time, but I really want a good long run solution. Below you will see two samples of the same action with the two libraries, maybe this will motivate some of you to let me know your thoughts. WITH THREE SHARP LIBRARY: public IQueryable<T> FindAllBuckets<T>() { List<string> list = new List<string>(); using (BucketListRequest request = new BucketListRequest(null)) using (BucketListResponse response = service.BucketList(request)) { XmlDocument bucketXml = response.StreamResponseToXmlDocument(); XmlNodeList buckets = bucketXml.SelectNodes("//*[local-name()='Name']"); foreach (XmlNode bucket in buckets) { list.Add(bucket.InnerXml); } } return list.Cast<T>().AsQueryable(); } WITH LITS3 LIBRARY: public IQueryable<T> FindAllBuckets<T>() { return _repository.GetAllBuckets() .Cast<T>() .AsQueryable(); }

  • Facebook charset detection mechanism?

    - by Void
    Today, I have looked into HTML code of facebook.com, and found something like this: <input type="hidden" value="€,´,€,´,?,?,?" name="charset_test"/> It's repeated two times inside the <form>...</form>. Any idea what this code might be useful for - some kind of server-side client charset detection? As far as I know, browser charset is being transmitted in HTTP request anyway (an "Accept-Charset" header).

  • OpenRasta overwriting Content-Length header in HEAD responses

    - by Dave Nichol
    I'm creating a pretty simple HTTP service using OpenRasta. For HEAD requests, the HTTP 1.1 spec states that HEAD requests should have the Content-Length set to "the size of the entity-body that would have been sent had the request been a GET" (section 14.13). However, OpenRasta apparently sees that the response body is empty and automatically sets the Content-Length header to "0". What is the recommended way to override this behavior? Thanks-

  • How to know when to close socket when dealing with HTTP clients?

    - by Y_Y
    Hi, How can I know when to close the socket of an HTTP client (I mean a browser is connecting to my TCP socket server). Everything works perfect but in other for the browser to show what the server has sent, i have to shutdown the server (or call socket.Close()). It works fine if I call (socket.Close()) but I just don't know when.? I don't want to call close in a middle of a request otherwise the browser would have to reload to connect to the server again.

  • On Redirect - Failed to generate a user instance of SQL Server...

    - by Craig Russell
    Hello (this is a long post sorry), I am writing a application in ASP.NET MVC 2 and I have reached a point where I am receiving this error when I connect remotely to my Server. Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed. I thought I had worked around this problem locally, as I was getting this error in debug when site was redirected to a baseUrl if a subdomain was invalid using this code: protected override void Initialize(RequestContext requestContext) { string[] host = requestContext.HttpContext.Request.Headers["Host"].Split(':'); _siteProvider.Initialise(host, LiveMeet.Properties.Settings.Default["baseUrl"].ToString()); base.Initialize(requestContext); } protected override void OnActionExecuting(ActionExecutingContext filterContext) { if (Site == null) { string[] host = filterContext.HttpContext.Request.Headers["Host"].Split(':'); string newUrl; if (host.Length == 2) newUrl = "http://sample.local:" + host[1]; else newUrl = "http://sample.local"; Response.Redirect(newUrl, true); } ViewData["Site"] = Site; base.OnActionExecuting(filterContext); } public Site Site { get { return _siteProvider.GetCurrentSite(); } } The Site object is returned from a Provider named siteProvider, this does two checks, once against a database containing a list of all available subdomains, then if that fails to find a valid subdomain, or valid domain name, searches a memory cache of reserved domains, if that doesn't hit then returns a baseUrl where all invalid domains are redirected. locally this worked when I added the true to Response.Redirect, assuming a halting of the current execution and restarting the execution on the browser redirect. What I have found in the stack trace is that the error is thrown on the second attempt to access the database. #region ISiteProvider Members public void Initialise(string[] host, string basehost) { if (host[0].Contains(basehost)) host = host[0].Split('.'); Site getSite = GetSites().WithDomain(host[0]); if (getSite == null) { sites.TryGetValue(host[0], out getSite); } _site = getSite; } public Site GetCurrentSite() { return _site; } public IQueryable<Site> GetSites() { return from p in _repository.groupDomains select new Site { Host = p.domainName, GroupGuid = (Guid)p.groupGuid, IsSubDomain = p.isSubdomain }; } #endregion The Linq query ^^^ is hit first, with a filter of WithDomain, the error isn't thrown till the WithDomain filter is attempted. In summary: The error is hit after the page is redirected, so the first iteration is executing as expected (so permissions on the database are correct, user profiles etc) shortly after the redirect when it filters the database query for the possible domain/subdomain of current redirected page, it errors out.

  • Internet Explorer buggy when accessing a custom weblogic provider

    - by James
    I've created a custom Weblogic Security Authentication Provider on version 10.3 that includes a custom login module to validate users. As part of the provider, I've implemented the ServletAuthenticationFilter and added one filter. The filter acts as a common log on page for all the applications within the domain. When we access any secured URLs by entering them in the address bar, this works fine in IE and Firefox. But when we bookmark the link in IE an odd thing happens. If I click the bookmark, you will see our log on page, then after you've successfully logged into the system the basic auth page will display, even though the user is already authenticated. This never happens in Firefox, only IE. It's also intermittent. 1 time out of 5 IE will correctly redirect and not show the basic auth window. Firefox and Opera will correctly redirect everytime. We've captured the response headers and compared the success and failures, they are identical. final boolean isAuthenticated = authenticateUser(userName, password, req); // Send user on to the original URL if (isAuthenticated) { res.sendRedirect(targetURL); return; } As you can see, once the user is authenticated I do a redirect to the original URL. Is there a step I'm missing? The authenticateUser() method is taken verbatim from an example in Oracle's documents. private boolean authenticateUser(final String userName, final String password, HttpServletRequest request) { boolean results; try { ServletAuthentication.login(new CallbackHandler() { @Override public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException { for (Callback callback : callbacks) { if (callback instanceof NameCallback) { NameCallback nameCallback = (NameCallback) callback; nameCallback.setName(userName); } if (callback instanceof PasswordCallback) { PasswordCallback passwordCallback = (PasswordCallback) callback; passwordCallback.setPassword(password.toCharArray()); } } } }, request); results = true; } catch (LoginException e) { results = false; } return results; I am asking the question here because I don't know if the issue is with the Weblogic config or the code. If this question is more suited to ServerFault please let me know and I will post there. It is odd that it works everytime in Firefox and Opera but not in Internet Explorer. I wish that not using Internet Explorer was an option but it is currently the company standard. Any help or direction would be appreciated. I have tested against IE 6 & 8 and deployed the custom provider on 3 different environments and I can still reproduce the bug.
