  • ASP.NET impersonations?

    - by asaf
    Hi! I have a aspx file that suppose to write to a file in the server while loading. On the local machine it works fine, but when i deploy it to a live server it gives me an exception "Access to the path 'd:\DZHosts\LocalUser\asafz83\www.asafz83.somee.com\lala.htm' is denied." WHen i asked my serverAdmin for the reason - he told me to remove any impersonation from my web.config file. Well, my web.config file doesn't contain any impersonation, so i'm really confused: What can i do in order for this sealy-stupid application to work? thanks!

  • ASP.NET Thread Safety in aspx.cs code behind file

    - by Tim Michalski
    I am thinking of adding a DataContext as a member variable to my aspx.cs code-behind class for executing LinqToSql queries. Is this thread safe? I am not sure if a new instance of this code-behind class is created for each HTTP request, or if the instance is shared amongst all request threads? My fear is that I will get 10 simultaneous concurrent http requests that will be using the same database session. public partial class MyPage : System.Web.UI.Page { private DataContext myDB = new DataContext(); protected void MyAction_Click(object sender, EventArgs e) { myDB.DoWork(); } }

  • asp.net Web server control with child controls, event not firing

    - by bleeeah
    I have a simple web control (TaskList) that can have children (Task) which inherit from LinkButton, that can be added declaratively or programatically. This works ok, but I can't get the onclick event of a Task to be fired in my code behind. The code .. [ToolboxData("<{0}:TaskList runat=\"server\"> </{0}:TaskList>")] [ParseChildren(true)] [PersistChildren(false)] public class TaskList : System.Web.UI.Control { //[DefaultProperty("Text")] public TaskList() {} private List<Task> _taskList = new List<Task>(); private string _taskHeading = ""; public string Heading { get { return this._taskHeading; } set { this._taskHeading = value; } } [NotifyParentProperty(true)] [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public List<Task> Tasks { get { return this._taskList; } set { this._taskList = value; } } protected override void CreateChildControls() { foreach (Task task in this._taskList) this.Controls.Add(task); base.CreateChildControls(); } protected override void Render(HtmlTextWriter writer) { writer.Write("<h2>" + this._taskHeading + "</h2>"); writer.Write("<div class='tasks_container'>"); writer.Write("<div class='tasks_list'>"); writer.Write("<ul>"); foreach (Task task in this._taskList) { writer.Write("<li>"); task.RenderControl(writer); writer.Write("</li>"); } writer.Write("</ul>"); writer.Write("</div>"); writer.Write("</div>"); } } public class Task : LinkButton { private string _key = ""; public string Key { get { return this._key; } set { this._key = value; } } } Markup: <rf:TaskList runat="server" ID="tskList" Heading="Tasks"> <Tasks> <rf:Task Key="ba" ID="L1" Text="Helllo" OnClick="task1_Click" runat="server" /> </Tasks> </rf:TaskList> The Onclick event task1_Click never fires when clicked (although a postback occurs).

  • Windows media player control with .NET

    - by brovar
    What I want to do is to read media files (pics and videos) from a directory and display them one by one using the WMP control (AxWMPLib.AxWindowsMediaPlayer). In its older version it was enough to check the file's duration to distinguish images from videos, the new one randomly shows movies' duration properly or as zero. Does anyone know any other way of finding out what file is being proceeded withouth checking its extension (as a file can have an extension of .abc or so)? I'll be very grateful for any help. (Sorry for my lousy English.)

  • If .net sha1 hash expects a byte array, and php sha1() wants a string, can I match the results?

    - by lynn
    I have a set of bytes I want to apply an sha1 hash to. One hash will be in .net, the other in PHP. Then I'll test to see if they match. In .net, you can create a byte array and use sha.ComputeHash(). byte[] data = new byte[DATA_SIZE]; byte[] result; SHA1 sha = new SHA1CryptoServiceProvider(); // This is one implementation of the abstract class SHA1. result = sha.ComputeHash(data); In PHP, you call sha1($string). I can't do anything about the .net side of the code, but how can I get the same hash out of PHP that .net will generate? Please note: I am ONLY able to work on the PHP side of this. The .net stuff is fixed and can't be modified. Thanks!

  • Multithreading A Function in VB.Net

    - by Ben
    I am trying to multi thread my application so as it is visible while it is executing the process, this is what I have so far: Private Sub SendPOST(ByVal URL As String) Try Dim DataBytes As Byte() = Encoding.ASCII.GetBytes("") Dim Request As HttpWebRequest = TryCast(WebRequest.Create(URL.Trim & "/webdav/"), HttpWebRequest) Request.Method = "POST" Request.ContentType = "application/x-www-form-urlencoded" Request.ContentLength = DataBytes.Length Request.Timeout = 1000 Request.ReadWriteTimeout = 1000 Dim PostData As Stream = Request.GetRequestStream() PostData.Write(DataBytes, 0, DataBytes.Length) Dim Response As WebResponse = Request.GetResponse() Dim ResponseStream As Stream = Response.GetResponseStream() Dim StreamReader As New IO.StreamReader(ResponseStream) Dim Text As String = StreamReader.ReadToEnd() PostData.Close() Catch ex As Exception If ex.ToString.Contains("401") Then TextBox2.Text = TextBox2.Text & URL & "/webdav/" & vbNewLine End If End Try End Sub Public Sub G0() Dim siteSplit() As String = TextBox1.Text.Split(vbNewLine) For i = 0 To siteSplit.Count - 1 Try If siteSplit(i).Contains("http://") Then SendPOST(siteSplit(i).Trim) Else SendPOST("http://" & siteSplit(i).Trim) End If Catch ex As Exception End Try Next End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim t As Thread t = New Thread(AddressOf Me.G0) t.Start() End Sub However, the 'G0' sub code is not being executed at all, and I need to multi thread the 'SendPOST' as that is what slows the application.

  • ASP.NET MVC 2 Areas, Strange routing behavior

    - by user137348
    I've created an Area named "Admin". I've created also a controller(Pages) and a view(List) in this areas. When I run my app and enter the url "/Admin/Pages/List" I'm getting an The resource cannot be found error. When I enter /Pages/List, the Action method is hit but the view is not found,because the app is searching in wrong directories ~/Views/Pages/List.aspx ~/Views/Pages/List.ascx ~/Views/Shared/List.aspx ~/Views/Shared/List.ascx the view is in /Admin/Pages/List.

  • .NET: Split web application into multiple DLLs?

    - by aximili
    Is it possible to compile some code-behind (.cs) files (eg. all .cs file under a particular folder) into one DLL, and the rest into another DLL? We have some common codes and pages (aspx + cs files) that we want to use across many websites. We want this to compile into a DLL (eg. Common.dll). The rest of the files will be website-specific, unique to each website and should compile into another DLL (eg. Website3.dll) This is so that if we make changes to a common code-behind, we can just publish Common.dll onto all our websites. Is that possible using VS Web Developer Express 2008? Thanks in advance. EDIT: We are already using a class library, but not for pages (aspx+cs)

  • Trouble dragging and dropping gui components onto other .net forms using NHibernate

    - by IsaacB
    Hi, using VS2008, here. I have a GUI component that loads some stuff from a database mapped by nhibernate in its constructor. When I drag and drop this component onto another form from the toolbox, NHibernate complains that it can't find the config file in program files\visual studio 9\common7\ide. Why is it looking here for the cfg file? I'm actually calling database stuff through another project in the same solution, and the cfg file is located at the root of that project. copy/pasting the cfg file over to there does work, but I'm working with svn here and I don't want to have configuration files outside the repository. Something else that would help would be turning off how it tries to load the data in the form design screen. How would I do that?

  • Update Message on ASP.NET ModelPopupExtender

    - by John
    Hi, I have a form in a MS AJAX ModalPopup Extender, which is in a UpdatePanel (for async loading). Everything works as expected. There is one thing that I am trying to do but not sure how to do it. On form submission, there is server side validation on top of client side validation. My question is: what is the best way to display validation error messages if any? It would be ideal if the messages could be written to the popup asynchronously so that the popup is still there. If this is not possible, I am thinking of displaying the messages using the JavaScript alert box. Any insight and suggestions are greatly appreciated. John

  • vb.net Is there a simple way to add a sound to a button click

    - by user867621
    Is there a simple way of doing this I found this online and I am getting an error Declare Function apisndPlaySound Lib "winmm" Alias "sndPlaySoundA" _ (ByVal filename As String, ByVal snd_async As Long) As Long Function PlaySound(ByVal sWavFile As String) ' Purpose: Plays a sound.

End If End Function A call to PInvoke function 'WindowsApplication3!WindowsApplication3.Module1::apisndPlaySound' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

  • ASP.NET MVC Unit Testing Controllers - Repositories

    - by Brian McCord
    This is more of an opinion seeking question, so there may not be a "right" answer, but I would welcome arguments as to why your answer is the "right" one. Given an MVC application that is using Entity Framework for the persistence engine, a repository layer, a service layer that basically defers to the repository, and a delete method on a controller that looks like this: public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } I am looking for the proper way to Unit Test this. Currently, I have a fake repository that gets used in the service, and my unit test looks like this: [TestMethod] public void Delete_Post_Passes_With_State_4() { //Arrange var stateService = GetService(); var stateController = new StateController( stateService ); ViewResult result = stateController.Delete( 4 ) as ViewResult; var model = (State)result.ViewData.Model; //Act RedirectToRouteResult redirectResult = stateController.Delete( model ) as RedirectToRouteResult; stateController = new StateController( stateService ); var newresult = stateController.Delete( 4 ) as ViewResult; var newmodel = (State)newresult.ViewData.Model; //Assert Assert.AreEqual( redirectResult.RouteValues["action"], "Index" ); Assert.IsNull( newmodel ); } Is this overkill? Do I need to check to see if the record actually got deleted (as I already have Service and Repository tests that verify this)? Should I even use a fake repository here or would it make more sense just to mock the whole thing? The examples I'm looking at used this model of doing things, and I just copied it, but I'm really open to doing things in a "best practices" way. Thanks.

    I want to create dynamic LinkButton for image, <img> tag is not working dynamically so I am using LinkButton with image. I don't want to provide ID to LinkButton because I want to generate more LinkButton dynamically.

  • Load balancing and shedulling algorithms .NET

    - by Lukas Šalkauskas
    Hello there, so here is my problem: I have several different configuarion servers. I have different calculations (jobs), I can predict how long approx. each job will take to be caclulated. Also I have priorities. My question is how to keep all machines loaded 99-100% and shedule the jobs in the best way. Each machine can do several calculations at the time. Jobs are pushed to the machine. Central machine knows current load of each machine. Also I would like to to assign some king of machine learning here, because I will know statistics of each job (started, finished, cpu load etc.). How to distribute jobs(calculations) in the best possible way, also keep in mind priority. Any suggestions ? Ideas ? Algorithms ?

  • Where has MS Charting gone in .NET 4.0?

    - by zotty
    Forgive me for being a little naive perhaps, but it seems that System.Windows.Controls.DataVisualization.Charting has vanished from VS2010, and blend 4. I'm trying to make a bar graph with a line overlayed, but can't even get started because I can't find the appropriate controls. I know I could use an external graphing package, but I'd like to try the inbuilt controls first.

  • ASP.NET SqlDataSource update and create FK reference

    - by William
    The short version: I have a grid view bound to a data source which has a SelectCommand with a left join in it because the FK can be null. On Update I want to create a record in the FK table if the FK is null and then update the parent table with the new records ID. Is this possible to do with just SqlDataSources? The detailed version: I have two tables: Company and Address. The column Company.AddressId can be null. On my ascx page I am using a SqlDataSource to select a left join of company and address and a GridView to display the results. By having my UpdateCommand and DeleteCommand of the SqlDataSource execute two statements separated by a semi-colon I am able to use the GridView's Edit and Delete functionality to update both table simultaneously. The problem I have is when the Company.AddressId is null. What I need to have happen is have the data source create a record in the Address table and then update the Company table with the new Address.ID then proceed with the update as usual. I would like to do this with just data sources if possible for consistency/simplicity sake. Is it possible to have my data source do this, or perhaps add a second data source to the page to handle some of this? Once I have that working I can probably figure out how to make it work with the InsertCommand as well but if you are on a roll and have an answer for how to make that fly as well feel free to provide it. Thanks.
