  • How to stream video content in asp.net?

    - by Kon
    Hi, I have the following code which downloads video content: WebRequest wreq = (HttpWebRequest)WebRequest.Create(url); using (HttpWebResponse wresp = (HttpWebResponse)wreq.GetResponse()) using (Stream mystream = wresp.GetResponseStream()) { using (BinaryReader reader = new BinaryReader(mystream)) { int length = Convert.ToInt32(wresp.ContentLength); byte[] buffer = new byte[length]; buffer = reader.ReadBytes(length); Response.Clear(); Response.Buffer = false; Response.ContentType = "video/mp4"; //Response.BinaryWrite(buffer); Response.OutputStream.Write(buffer, 0, buffer.Length); Response.End(); } } But the problem is that the whole file downloads before being played. How can I make it stream and play as it's still downloading? Or is this up to the client/receiver application to manage?

  • Best Practice to write Connection string for heavy traffic ASP.NET Web Application

    - by hungrycoder
    What is the best way to define connection string for a web application that has minimum 500 live users on the internet in terms of connection pooling. And load factors to consider? Suppose I have connection string as follows: initial catalog=Northwind; Min Pool Size=20;Max Pool Size=500; data source=localhost; Connection Timeout=30; Integrated security=sspi" as Max Pool Size is 500 and as live users exceed 500 say 520 will the remaining 20 users experience slower page load?? Or what if I have connection string as follows which doesn't talks anything about pooling or Connection time out? How the application behaves then? initial catalog=Northwind; data source=localhost; Integrated security=sspi" I'm using "Using statements" however to access the MYSQL database.

  • Rendering a view to a string in ASP.NET MVC 2

    - by Frank Rosario
    We need to render an ActionResult to a string to add pages to our internal search engine index. We settled on this solution to render to string. I've run into a problem with the ExecuteResult call used to process the View. Code Snippet: var oldController = controllerContext.RouteData.Values["controller"]; controllerContext.RouteData.Values["controller"] = typeof(TController).Name.Replace("Controller", ""); viewResult.ExecuteResult(controllerContext); // this line breaks I receive the following error: "Object reference not set to instance of object" error. I've confirmed viewResult is not null, so the exception has to be thrown internally in ExecuteResult. What could we be missing?

  • Connection Timeout exception for a query using ADO.Net

    - by dragon
    Update: Looks like the query does not throw any timeout. The connection is timing out. This is a sample code for executing a query. Sometimes, while executing time consuming queries, it throws a timeout exception. I cannot use any of these techniques: 1) Increase timeout. 2) Run it asynchronously with a callback. This needs to run in a synchronous manner. please suggest any other techinques to keep the connection alive while executing a time consuming query? private static void CreateCommand(string queryString, string connectionString) { using (SqlConnection connection = new SqlConnection( connectionString)) { SqlCommand command = new SqlCommand(queryString, connection); command.Connection.Open(); command.ExecuteNonQuery(); } }

  • Dynamically Adding Multiple User Controls vb.net

    - by Jamie Hartnoll
    I have a User Control which returns a table of data, which in some cases needs to be looped, displaying one on top of another. I am able to dynamically add a single instance of this by placing a fixed placeholder in the page. I am now trying to work out how to add more than one, given that I don't know how many might be needed I don't want to hard code the Placeholders. I've tried the following, but I am just getting one instance, presumably the first is being overwritten by the second My HTML <div id="showHere" runt="server"/> VB Dim thisPh As New PlaceHolder thisPh.Controls.Add(showTable) showHere.Controls.Add(thisPh) Dim anotherPh As New PlaceHolder anotherPh .Controls.Add(showTable) showHere.Controls.Add(anotherPh) How do I make it add repeated tables within the showHere div?

  • ASP.NET custom server control: nested items

    - by Dylan Lin
    Hi, In the aspx code view, we can code like this: <asp:ListBox runat="server"> <asp:ListItem Text="Item1" /> <asp:ListItem Text="Item2" /> </asp:ListBox> However, the ListItem class is not a server control. How could we do that? Is there some attributes being consumed by the visual studio? Thanks:)

  • .net clipboard metadata (or whatever skype quotations use)

    - by Cyclone
    Is it possible to use the Clipboard class to grab all the data from the clipboard, like full skype quotes? They use some kind of metadata I think, which is how it knows when something is a quote or not. How can I access that from the Clipboard class? What functions would I call to set/restore Skype quotations? Thanks for the help!

  • set current user in asp.net mvc

    - by Tomh
    Hey guys, I'm not sure if this is the best way to do it, but I want to keep a user object alive during all requests of the current user. From reading several resources I learned that you should create your own IPrinciple which holds this. But I don't want to trigger the database every authentication request. Any recommendations on how to handle this? Is caching the db request a good idea? protected void Application_AuthenticateRequest(Object sender, EventArgs e) { HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie != null) { FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); User user; using (HgDataContext hg = new HgDataContext()) { if (Session["user"] != null) { user = (from u in hg.Users where u.EmailAddress == authTicket.Name select u).Single(); } else { user = Session["user"] as User; } } var principal = new HgPrincipal(user); Context.User = principal; } }

    View: function success(arg) { var obj = arg.get_response().get_object(); if (obj.ErrorMessage === '') { var answer = document.createElement('div'); answer.appendChild(document.createTextNode(obj.Answer)); document.getElementById('answers').appendChild(answer); } else { document.getElementById('errors').innerHTML = obj.ErrorMessage; } } <% using (Ajax.BeginForm("EditOrganizationMeta", "Organization", new AjaxOptions { HttpMethod = "POST", OnSuccess = "success" })) { %> <input type="submit" name="button<%=OrganizationMeta.vcr_MetaKey + Lang.int_LangId %>" value="Save" /> <div id="errors"></div> <div id="answers"></div> <% } %> Controller: [HttpPost] [ValidateInput(false)] public ActionResult EditOrganizationMeta(FormCollection collection) { return Json(new { Answer = "Record Successfully Saved", ErrorMessages = "Title is required" }); } The thing is that success method in the javascript is not getting the required parameters. It is printing undefined there. Is there a problem in javascript method OnSuccess?

  • Export database data to csv from view by date range asp.net mvc3

    - by Benjamin Randal
    I am trying to find a way to export data from my database and save it as a .csv file. Ideally the user will be able to select a date range on a view, which will display the data to be exported, then the user can click an "export to CSV" link. I've done quite a bit of searching and but have not found much specific enough to help me step through the process. Any help would be great. I would like to export data from this database model... { public class InspectionInfo { [Key] public int InspectionId { get; set; } [DisplayName("Date Submitted")] [DataType(DataType.Date)] // [Required] public DateTime Submitted { get; set; } [DataType(DataType.MultilineText)] [MaxLength(1000)] // [Required] public string Comments { get; set; } // [Required] public Contact Contact { get; set; } [ForeignKey("Contact")] public Int32 ContactId { get; set; } [MaxLength(100)] public String OtherContact { get; set; } I have a service for search also, just having difficulty implementing public SearchResults SearchInspections(SearchRequest request) { using (var db = new InspectionEntities()) { var results = db.InspectionInfos .Where( i=> ( (null == request.StartDate || i.Submitted >= request.StartDate.Value) && (null == request.EndDate || i.Submitted <= request.EndDate.Value) ) ) .OrderBy(i=>i.Submitted) .Skip(request.PageSize*request.PageIndex).Take(request.PageSize); return new SearchResults{ TotalResults=results.Count(), PageIndex=request.PageIndex, Inspections=results.ToList(), SearchRequest=request }; } }

  • get length of data sent over network to TCPlistener/networkstream vb.net

    - by Jonathan.
    It seems the most obvious thing, but I just can't work out how to get the length of bytes sent over a network using a TCPClient and TCPListener? This is my code so far: 'Must listen on correct port- must be same as port client wants to connect on. Const portNumber As Integer = 9999 Dim tcpListener As New TcpListener(IPAddress.Parse("192.168.2.7"), portNumber) tcpListener.Start() Console.WriteLine("Waiting for connection...") 'Accept the pending client connection and return 'a TcpClient initialized for communication. Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() Console.WriteLine("Connection accepted.") ' Get the stream Dim networkStream As NetworkStream = tcpClient.GetStream() '' Read the stream into a byte array I need to get the length of the networkstream to set the size of the array of bytes I'm going to read the data into. But the networkStream.length is unsupported and does not work and throws an Notsupportedexception. The only other way I can think of is to send the size of the data before sending the data, but this seems the long way round.

  • ASP.NET MVC null ViewResult

    - by David Neale
    How should one deal with an MVC controller returning a null ViewResult? As an example I am creating a simple edit view: public ActionResult Edit(int id) { var person = (from p in context.SWLiftShare_Persons where p.id == id select p).SingleOrDefault(); if (person != null) { return View(person); } else return View(); } I guess in reality there's no point in checking for a null result in the controller because the view picks out properties from the model: <h2>Edit - <%= Html.Encode(Model.Name) %></h2> <%= Html.ValidationSummary("Edit was unsuccessful. Please correct the errors and try again.") %> <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <p> <label for="id">id: <%= Html.Encode(Model.id) %></label> </p> <p> <label for="CollarNumber">CollarNumber:</label> <%= Html.TextBox("CollarNumber", Model.CollarNumber)%> <%= Html.ValidationMessage("CollarNumber", "*") %> </p> <p> <label for="Name">Name:</label> <%= Html.TextBox("Name", Model.Name)%> <%= Html.ValidationMessage("Name", "*") %> </p> <p> <label for="EmailAddress">EmailAddress:</label> <%= Html.TextBox("EmailAddress", Model.EmailAddress, new { style = "width:300px" })%> <%= Html.ValidationMessage("EmailAddress", "*") %> </p> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> I could just wrap everything in a <% if(Model != null) { //render edit markup... etc. but that seems rather unelegant. Is there a better way to deal with this?

  • VB.NET textbox changed but still hold initial value

    - by Jonesy
    Hi Folks, I've never come across this before: I have a series of text boxes. The text of these boxes get set on page load. then I have a submit button that calls a sub to update the table with the new values (text) in the text box. The problem is it is keeping the original text not the text that is CURRENTLY in the textbox. Anyone come across this before? Or know how to get round it? Cheers, Jonesy

  • ASP.Net ViewState doesn't work when Control become Enable=False

    - by Daok
    Why when a control does contain value but it's set to .Enable=False that all controls become disable (that's ok) but why that the ViewState doesn't retain the data on the next post back? If I get the UserControl without modifing its Enable state, the ViewState work between post back. How can we disable a UserControl that all its control become disable (this part work) but all of them KEEP use the ViewState (this doesn't work)?

  • Help understanding .NET delegates, events, and eventhandlers

    - by Seth Spearman
    Hello, In the last couple of days I asked a couple of questions about delegates HERE and HERE. I confess...I don't really understand delegates. And I REALLY REALLY REALLY want to understand and master them. (I can define them--type safe function pointers--but since I have little experience with C type languages it is not really helpful.) Can anyone recommend some online resource(s) that will explain delegates in a way that presumes nothing? This is one of those moments where I suspect that VB actually handicaps me because it does some wiring for me behind the scenes. The ideal resource would just explain what delegates are, without reference to anything else like (events and eventhandlers), would show me how all everything is wired up, explain (as I just learned) that delegates are types and what makes them unique as a type (perhaps using a little ildasm magic)). That foundation would then expand to explain how delegates are related to events and eventhandlers which would need a pretty good explanation in there own right. Finally this resource could tie it all together using real examples and explain what wiring DOES happen automatically by the compiler, how to use them, etc. And, oh yeah, when you should and should not use delegates, in other words, downsides and alternatives to using delegates. What say ye? Can any of you point me to resource(s) that can help me begin my journey to mastery? EDIT One last thing. The ideal resource will explain how you can and cannot use delegates in an interface declaration. That is something that really tripped me up. Thanks for your help. Seth
