  • BinaryWrite exception "OutputStream is not available when a custom TextWriter is used" in MVC 2 ASP.

    - by Grant
    Hi, I have a view rendering a stream using the response BinaryWrite method. This all worked fine under ASP.NET 4 using the Beta 2 but throws this exception in the RC release: "HttpException" , "OutputStream is not available when a custom TextWriter is used." <%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage" %> <%@ Import Namespace="System.IO" %> <script runat="server"> protected void Page_Load(object sender, EventArgs e) { if (ViewData["Error"] == null) { Response.Buffer = true; Response.Clear(); Response.ContentType = ViewData["DocType"] as string; Response.AddHeader("content-disposition", ViewData["Disposition"] as string); Response.CacheControl = "No-cache"; MemoryStream stream = ViewData["DocAsStream"] as MemoryStream; Response.BinaryWrite(stream.ToArray()); Response.Flush(); Response.Close(); } } </script> </script> The view is generated from a client side redirect (jquery replace location call in the previous page using Url.Action helper to render the link of course). This is all in an iframe. Anyone have an idea why this occurs?

  • Struggling running ASP MVC2 on IIS6.0

    - by Luke
    Hi I could use a little Help using MVC2 on an IIS6.0 Its an MVC2 RC2 [.NET 3.5]. I followed the famous Haacked Tutorial, created a virtual folder, created a Default.aspx Website for my Project, put everything to my virtual folder. The routing is modified, using wildcard mapping [anyway its not running without, too], according to the Tutorial. I also checked, that all Webservices are running [asp.net 2 / asp.net 4 / active server pages]. The routing is working fine on my development machine, even checked it using Haacks routing debugger ... [http://haacked.com/archive/2008/03/13/url-routing-debugger.aspx] Seems fine so far, but I get only 404 - not found errors. Is there something I might be missing ? Global.asax.cs public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}.mvc/{action}/{id}", new { action = "Index", id = "" } ); routes.MapRoute( "Root", "", new { controller = "Home", action = "Index", id = "" } ); } Default.aspx.cs public void Page_Load(object sender, System.EventArgs e) { // Change the current path so that the Routing handler can correctly interpret // the request, then restore the original path so that the OutputCache module // can correctly process the response (if caching is enabled). string originalPath = Request.Path; HttpContext.Current.RewritePath(Request.ApplicationPath, false); IHttpHandler httpHandler = new MvcHttpHandler(); httpHandler.ProcessRequest(HttpContext.Current); HttpContext.Current.RewritePath(originalPath, false); }

  • XmlSerializer one Class that has multiple classes properties

    - by pee2002
    Hi there! Objective: Serialize all the public properties of the ClassMain: public class ClassMain { ClassA classA = new ClassA(); public ClassMain() { classA.Prop1 = "Prop1"; classA.Prop2 = "Prop2"; } public string Prop1 { get; set; } public string Prop2 { get; set; } public ClassA ClassA { get { return classA; } } } ClassA: public class ClassA { public string Prop1 { get; set; } public string Prop2 { get; set; } } This is how i´m serializing: private void button1_Click(object sender, EventArgs e) { ClassMain classMain = new ClassMain(); classMain.Prop1 = "Prop1"; classMain.Prop2 = "Prop2"; XmlSerializer mySerializer = new XmlSerializer(typeof(ClassMain)); StreamWriter myWriter = new StreamWriter("xml1.xml"); mySerializer.Serialize(myWriter, classMain); myWriter.Close(); } In this case, the xml output is: <?xml version="1.0" encoding="utf-8"?> <ClassMain xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Prop1>Prop1</Prop1> <Prop2>Prop2</Prop2> </ClassMain> As you see, is lacking the ClassA properties. Can anyone help me out? Regards

  • Telerik ASP.NET AJAX - Ajax Update Label with dynamic created Docks

    - by csharpnoob
    Hi, i try to Update a simple Label on Close Event of dynamic created RadDock. Works fine so far, Label gets the correct values but doesnt updates it. RadDock dock = new RadDock(); dock.DockMode = DockMode.Docked; dock.UniqueName = Guid.NewGuid().ToString(); dock.ID = string.Format("RadDock{0}", dock.UniqueName); dock.Title = slide.slideName; dock.Text = string.Format("Added at {0}", DateTime.Now); dock.Width = Unit.Pixel(300); dock.AutoPostBack = true; dock.CommandsAutoPostBack = true; dock.Command += new DockCommandEventHandler(dock_Command); ... void dock_Command(object sender, DockCommandEventArgs e) { Status.Text = "Removed " + ((RadDock)sender).Title + " " + ((RadDock)sender).Text; } I tried to do this: RadAjaxManager1.AjaxSettings.AddAjaxSetting(dock, Status, null); while creating the docks, but on runtime i get a NullReference Excepetion. On a Button registered with the RadAjaxManager it works to show the value assigned by dock_command. protected void Button1_Click(object sender, EventArgs e) { Status.Text = Status.Text; } UPDATE: The RadAjaxManager was created with integrated Wizzard of VS2008. Can't select the Docks, because the are generated while runtime. On Backend its included in AutoCompletion, so the NullReference has nothing to do with the AjaxManager itself. Like i said, works fine with the Button. <telerik:RadAjaxManager ID="RadAjaxManager1"> <telerik:AjaxSetting AjaxControlID="Button1"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="Label1"></telerik:AjaxUpdatedControl> </UpdatedControls> </telerik:AjaxSetting>

  • ASP.NET how to use __doPostBack from Custom JavaScript with Master/Content Pages

    - by harrije
    In a simple aspx page I can have a custom JavaScript function postback as described in http://www.xefteri.com/articles/show.cfm?id=18 The simple page uses a linkbutton: <asp:LinkButton id="CreateFile" runat="server" onclick="CreateFile_Click" /> with code behind that has the VB subroutine: Sub CreateFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) and a Javascript custom function that does: __doPostBack('CreateFile',''); When I move the code to a content page with a corresponding master page the simple example no longer works. I'm aware that server control IDs are changed in the generated HTML when a master page is involved, and I'm using the correct IDs in the Javascript. As an example, for the LinkButton ID I use '<%=CreateFile.ClientID%' for the Javascript in the generated HTML. Never the less, I still can't figure out how to get postbacks from the Javascript when master pages are involved. More accurately, with a master page in the mix the code won't even compile but results in: 'CreateFile_Click' is not a member of 'ASP.testmaster_aspx' If I remove onclick="CreateFile_Click" from the LinkButton markup it compiles but does not work. Similary if onclick is removed from the simpler version without a master page it does not work either, as expected. Any input on how to get postback from a custom Javascript function when using master pages would be much appreciated.

  • Mimicking the UltraGridColumnChooser's drag & drop ability

    - by Sören Kuklau
    (Infragistics 2008 Vol. 3, CLR 2.0) Infragistics's UltraGrid comes with a column chooser user control, which is simply a vertical arrangement of columns with checkboxes that toggle a column's hidden state. In addition, it allows you to pick a column and drag it directly to the grid so you don't have to manually position it afterwards. (This is particularly handy when you already have a lot of visible columns and have no clue where the new one ended up.) I'm building my own column chooser based on an UltraTree. Getting the checkboxes to behave the same wasn't an issue, but I haven't found a way to drag a column from the tree to the grid and have it accept it. In my tree, each UltraTreeNode has a Tag with the following struct: Private Structure DraggableGridColumn Public NodeKey As String Public NodeName As String Public ParentKey As String Public Column As UltraGridColumn End Structure I then have an event as follows: Private Sub columnsTree_SelectionDragStart(ByVal sender As Object, ByVal e As System.EventArgs) Handles columnsTree.SelectionDragStart If columnsTree.SelectedNodes.Count <> 1 Then Return End If If Not TypeOf columnsTree.SelectedNodes(0).Tag Is DraggableGridColumn Then Return End If Dim column As UltraGridColumn = CType(columnsTree.SelectedNodes(0).Tag, DraggableGridColumn).Column columnsTree.DoDragDrop(column, DragDropEffects.All) End Sub In the DoDragDrop call, neither column (of type UltraGridColumn) nor column.Header (of type ColumnHeader) get accepted by the grid. I assume I'm sending the wrong type, and/or that the grid expects a special struct with some additional information. Unfortunately, I've also failed to catch an event (both on the column chooser side as well as on the grid side) where Infragistics's normal column chooser does this properly; the normal drag & drop events never seem to fire.

  • Using Ghostscript in a Webapplication (PDF Thumbnails)

    - by cpt.oneeye
    Hello, i am using the ghostscriptsharp wrapper for c# and ghostscript. I want to generate thumbnails out of pdf-files. Further Information on the sample-code are given here. There are different Methods imported form the ghostscript-c-dll "gsdll32.dll". [DllImport("gsdll32.dll", EntryPoint = "gsapi_new_instance")] private static extern int CreateAPIInstance(out IntPtr pinstance, IntPtr caller_handle); [DllImport("gsdll32.dll", EntryPoint = "gsapi_init_with_args")] private static extern int InitAPI(IntPtr instance, int argc, IntPtr argv); //...and so on I am using the GhostscriptWrapper for generating the thumbnails in a webapplication (.net 2.0). This class uses the methods imported above. protected void Page_Load(object sender, EventArgs e){ GhostscriptWrapper.GeneratePageThumb("c:\\sample.pdf", "c:\\sample.jpg", 1, 100, 100); } When i debug the Web-Application in Visual Studio 2008 by hitting key "F5" it works fine (a new instance of webserver is generated). When i create a WindowsForm Application it works too. The thumbnails get generated. When i access the application with the webbrowser directly (http://localhoast/mywebappliation/..) it doesn't work. No thumbnails are generated. But there is also no exception thrown. I placed the gsdll32.dll in the system32-folder of windows xp. The Ghostscript Runtime is installed too. I have given full access in the IIS-Webproject (.Net 2.0). Does anybody know why i can't access Ghostscript from my webapplication? Are there any security-issues for accessing dll-files on the IIS-Server? Greetings Klaus

  • How to implement EntityDataSource Where IN entity sql clause

    - by TonyS
    I want to pass a number of values into a parameter of the EntityDataSource, e.g.: Where="it.ORDER_ID IN {@OrderIdList}" (this is a property on the EntityDataSource) <WhereParameters> <asp:ControlParameter Name="OrderIdList" Type="Int16" ControlID="OrderFilterControl" PropertyName="OrderIdList" /> </WhereParameters> This doesn't work as ORDER_ID is of type int32 and I need to pass in multiple values, e.g. {1,2,3} etc The next thing I tried was setting the Where clause in code-behind and this all works except I can't get data binding on DropDownLists to work. By this I mean no value is returned from the bound dropdownlists in the EntityDataSource Updating Event. My ideal solution would be to use a WhereParameter on the EntityDataSource but any help is appreciated. Thanks, Tony.

  • ASP.NET 4.0 UpdatePanel and UserControl with PlaceHolder

    - by Chris
    I don't know if this is ASP.NET 4.0 specific but I don't recall having this problem in previous versions. I have very simple user control called "TestModal" that contains a PlaceHolder control which I use to instantiate a template in. When I put an UpdatePanel inside this UserControl on the page the updatepanel only does full postbacks and not partial postbacks. What gives?

  • Autofac WCF integration + sessions

    - by Michael Sagalovich
    I am having an ASP.NET MVC 3 application that collaborates with a WCF service, which is hosted using Autofac host factory. Here are some code samples: .svc file: <%@ ServiceHost Language="C#" Debug="true" Service="MyNamespace.IMyContract, MyAssembly" Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf" %> Global.asax of the WCF service project: protected void Application_Start(object sender, EventArgs e) { ContainerBuilder builder = new ContainerBuilder(); //Here I perform all registrations, including implementation of IMyContract AutofacServiceHostFactory.Container = builder.Build(); } Client proxy class constructor (MVC side): ContainerBuilder builder = new ContainerBuilder(); builder.Register(c => new ChannelFactory<IMyContract>( new BasicHttpBinding(), new EndpointAddress(Settings.Default.Url_MyService))) .SingleInstance(); builder.Register(c => c.Resolve<ChannelFactory<IMyContract>>().CreateChannel()) .UseWcfSafeRelease(); _container = builder.Build(); This works fine until I want WCF service to allow or require sessions ([ServiceContract(SessionMode = SessionMode.Allowed)], or [ServiceContract(SessionMode = SessionMode.Required)]) and to share one session with the MVC side. I changed the binding to WSHttpBinding on the MVC side, but I am having different exceptions depending on how I tune it. I also tried changing AutofacServiceHostFactory to AutofacWebServiceHostFactory, with no result. I am not using config file as I am mainly experimenting, not developing real-life application, but I need to study the case. But if you think I can achieve what I need only with config files, then OK, I'll use them. I will provide exception details for each combination of settings if required, I'm omitting them not to make the post too large. Any ideas on what I can do?

  • C# update GUI continuously from backgroundworker.

    - by Qrew
    I have created a GUI (winforms) and added a backgroundworker to run in a separate thread. The backgroundworker needs to update 2 labels continuously. The backgroundworker thread should start with button1 click and run forever. class EcuData { public int RPM { get; set; } public int MAP { get; set; } } private void button1_Click(object sender, EventArgs e) { EcuData data = new EcuData { RPM = 0, MAP = 0 }; BackWorker1.RunWorkerAsync(data); } private void BackWorker1_DoWork(object sender, DoWorkEventArgs e) { EcuData argumentData = e.Argument as EcuData; int x = 0; while (x<=10) { // // Code for reading in data from hardware. // argumentData.RPM = x; //x is for testing only! argumentData.MAP = x * 2; //x is for testing only! e.Result = argumentData; Thread.Sleep(100); x++; } private void BackWorker1_RunWorkerCompleted_1(object sender, RunWorkerCompletedEventArgs e) { EcuData data = e.Result as EcuData; label1.Text = data.RPM.ToString(); label2.Text = data.MAP.ToString(); } } The above code just updated the GUI when backgroundworker is done with his job, and that's not what I'm looking for.

  • JQuery BlockUI with UpdatePanel Viewstate Issue

    - by Chris
    I am using BlockUI to show a modal. Within the blocked modal I have an update panel. Within the update panel I have a textbox and a button that submits the content back to the server. Everything works fine up to this point (the blockUI is called, the modal appears, and the button performs the postback). However, when the button's click event is fired the value for the textbox is consistently empty even if text was entered. When the update panel updates the textbox shows up blank. It appears that this may be some sort of viewstate issue and I haven't turned off viewstate. <a href="javascript:$.blockUI({ message: $('#divTest') });">SHOW MODAL</a> <div id="divTest" style="display: none;"> <asp:UpdatePanel ID="upTest" UpdateMode="Conditional" runat="server"> <ContentTemplate> <asp:TextBox ID="txtTestVS" runat="server" /><br /> <asp:Button ID="cmdTest" Text="TEST" OnClick="cmdTest_Click" UseSubmitBehavior="false" runat="server" /> </ContentTemplate> </asp:UpdatePanel> SERVER-SIDE: protected void cmdTest_Click(object sender, EventArgs e) { string x = txtTestVS.Text; } String "x" always equal "".

  • Asp.Net membership via ASP.NET Website Administrator Tool

    - by luppi
    I created a database with aspnet_regsql, the database was created in sql sever 2008 and not in data folder in my project (do I need to move it to the folder manually?). Next, in Web Site Administration Tool I went to provider section and clicked don Test button. I got an error: Could not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider. Maybe I need to set something in a web.config, like membership settings or connection strings (or ASP.NET Website Administrator Tool should create those settings for me)? Update: Maybe it happens because I am using SQL server 2008 full and not express? Update 2: After setting membership section and connection string to my aspnetdb database in Web Site Administration Tool I've opened security-Security Setup Wizard-Define Roles (stage 4) I got this error: An error was encountered. Please return to the previous page and try again. The following message may help in diagnosing the problem: Unable to connect to SQL Server database. at System.Web.Administration.WebAdminPage.CallWebAdminHelperMethod(Boolean isMembership, String methodName, Object[] parameters, Type[] paramTypes) at ASP.security_wizard_wizardpermission_ascx.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

  • Deselect dates in Web Calendar c#

    - by yomismo
    Hello, I'm trying to select and de-select dates on a C# Web Calendar control. The problem I have is that I can select or deselect dates except when there is only a single date selected. Clicking on it does not trigger the selection changed event, so Ineed to do something on the dayrender event but I'm not sure what or how. Any ideas? TIA Code so far: public static List<DateTime> list = new List<DateTime>(); protected void Calendar1_DayRender(object sender, DayRenderEventArgs e) { if (e.Day.IsSelected == true) { list.Add(e.Day.Date); } Session["SelectedDates"] = list; } protected void Calendar1_SelectionChanged(object sender, EventArgs e) { DateTime selection = Calendar1.SelectedDate; if (Session["SelectedDates"] != null) { List<DateTime> newList = (List<DateTime>)Session["SelectedDates"]; foreach (DateTime dt in newList) { Calendar1.SelectedDates.Add(dt); } if (searchdate(selection, newList)) { Calendar1.SelectedDates.Remove(selection); } list.Clear(); } } public bool searchdate(DateTime date, List<DateTime> dates) { var query = from o in dates where o.Date == date select o; if (query.ToList().Count == 0) { return false; } else { return true; } }

  • Problem with ScriptManager.RegisterStartupScript in WebControl nested in UpdatePanel

    - by Chris
    Hello, I am having what I believe should be a fairly simple problem, but for the life of me I cannot see my problem. The problem is related to ScriptManager.RegisterStartupScript, something I have used many times before. The scenario I have is that I have a custom web control that has been inserted into a page. The control (and one or two others) are nested inside an UpdatePanel. They are inserted onto the page onto a PlaceHolder: <asp:UpdatePanel ID="pnlAjax" runat="server"> <ContentTemplate> <asp:PlaceHolder ID="placeholder" runat="server"> </asp:PlaceHolder> ... protected override void OnInit(EventArgs e){ placeholder.Controls.Add(Factory.CreateControl()); base.OnInit(e); } This is the only update panel on the page. The control requires some initial javascript be run for it to work correctly. The control calls: ScriptManager.RegisterStartupScript(this, GetType(), Guid.NewGuid().ToString(), script, true); and I have also tried: ScriptManager.RegisterStartupScript(Page, Page.GetType(), Guid.NewGuid().ToString(), script, true); The problem is that the script runs correctly when the page is first displayed, but does not re-run after a partial postback. I have tried the following: Calling RegisterStartupScript from CreateChildControls Calling RegisterStartupScript from OnLoad / OnPreRender Using different combinations of parameters for the first two parameters (in the example above the Control is Page and Type is GetType(), but I have tried using the control itself, etc). I have tried using persistent and new ids (not that I believe this should have a major impact either way). I have used a few breakpoints and so have verified that the Register line is being called correctly. The only thing I have not tried is using the UpdatePanel itself as the Control and Type, as I do not believe the control should be aware of the update panel (and in any case there does not seem to be a good way of getting the update panel?). Can anyone see what I might be doing wrong in the above? Thanks :)

  • Hidden/Shown AsyncFileUpload Control Doesn't Fire Server-Side UploadedComplete Event

    - by Bob Mc
    I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false. Example: Page code - <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %> . . . <act:ToolkitScriptManager runat="server" ID="ScriptManager1" /> <asp:UpdatePanel runat="server" ID="upnlFileUpload"> <ContentTemplate> <asp:Button runat="server" ID="btnShowUpload" Text="Show Upload" /> <div runat="server" id="divUpload" visible="false"> <act:AsyncFileUpload runat="server" id="ctlFileUpload" /> </div> </ContentTemplate> </asp:UpdatePanel> Server-side Code - Protected Sub ctlFileUpload_UploadedComplete(ByVal sender As Object, ByVal e As AjaxControlToolkit.AsyncFileUploadEventArgs) Handles ctlFileUpload.UploadedComplete End Sub Protected Sub btnShowUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnShowUpload.Click divUpload.Visible = True End Sub I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the <div>, making it visible at initial page render, the control works as expected. So, is this a bug within the AsynchUploadControl, or am I not grasping a fundamental concept (which happens regularly)?

  • Visual C# GUI Designer - Recommended way of removing generated event handler-code & basic tutorial

    - by cusack
    Hi, I'm new to the Visual C# designer so these are general and pretty basic question on how to work with the designer. When we for instance add a label to a form and then double-click on it in the Visual C# designer (I'm using Microsoft Visual C# 2008 Express Edition), the following things happen: The designer generates code within Form1.Designer.cs (assume default names for simplicity) to add the label, then with the double-click it will add the event handler label1_Click to the label within Form1.Designer.cs, using the following code this.label1.Click += new System.EventHandler(this.label1_Click); and it adds the event handler method to Form1.cs private void label1_Click(object sender, EventArgs e) { } If I now remove the label only the code within Form1.Designer.cs will be removed but the label1_Click method will stay within Form1.cs even if it isn't used by anything else. But if I'm using reset within Properties-Events for the Click-event from within the designer even the label1_Click method in Form1.cs will be removed. 1.) Isn't that a little inconsistent behavior? 2.) What is the recommended way of removing such generated event handler-code? 3.) What is the best "mental approach"/best practice for using the designer? I would approach it by mental separation in the way that Form1.cs is 100% my responsibility and that on the other hand I'm not touching the code in Form1.Designer.cs at all. Does that make sense or not? Since sometimes the designer removes sth. from Form1.cs I'm not sure about this. 4.) Can you recommend a simple designer tutorial that assumes no Visual C# designer knowledge but expects/doesn't explain C#. The following one is an example of what I would not want it explains what a c#-comment is and I'd prefer text over video as well: http://msdn.microsoft.com/en-us/beginner/bb964631.aspx

  • How to get record value from LinqDataSource via Code Behind

    - by rockinthesixstring
    I've got a LinqDataSource that retrieves a single record. Protected Sub LinqDataSource1_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceSelectEventArgs) Handles LinqDataSource1.Selecting Dim BizForSaleDC As New DAL.BizForSaleDataContext e.Result = BizForSaleDC.bt_BizForSale_GetByID(e.WhereParameters("ID")).FirstOrDefault End Sub I'd like to be able to retrieve the values of said DataSource using the Page_Load function. Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load 'Get the right usercontrol' Dim ctrl As UserControl Select Case DataBinder.Eval(LINQDATASOURCE_SOMETHING.DataItem, "AdType") Case 1 : ctrl = DirectCast(Me.FindControl("Default1"), UserControl) Case 2 : ctrl = DirectCast(Me.FindControl("Default1"), UserControl) Case 3 : ctrl = DirectCast(Me.FindControl("ValuPro1"), UserControl) Case 4 : ctrl = DirectCast(Me.FindControl("ValuPro1"), UserControl) Case Else : ctrl = Nothing End Select 'set the control to visible' ctrl.Visible = True End Sub But obviously the code above doesn't work... I'm just wondering if there's a way to make it work. Here is the full markup <body> <form id="form1" runat="server"> <asp:LinqDataSource ID="LinqDataSource1" runat="server"> <WhereParameters> <asp:QueryStringParameter ConvertEmptyStringToNull="true" Name="ID" QueryStringField="ID" Type="Int32" /> </WhereParameters> </asp:LinqDataSource> <uc:Default ID="Default1" runat="server" Visible="false" /> <uc:ValuPro ID="ValuPro1" runat="server" Visible="false" /> </form> </body> </html> Basically what happens is the appropriate usercontrol is enabled and that usercontrol inherits the LinqDataSource and displays the appropriate information. EDIT: It's working now with the code below, however, since I'm really not into hitting the database multiple times for the same info, I'd prefer to get the value from the DataSource. 'Query the database' Dim _ID As Integer = Convert.ToInt32(Request.QueryString("ID")) Dim BizForSaleDC As New BizForSaleDataContext Dim results = BizForSaleDC.bt_BizForSale_GetByID(_ID).FirstOrDefault 'Get the right usercontrol' Dim ctrl As UserControl Select Case results.AdType Case 1 : ctrl = DirectCast(Me.FindControl("Default1"), UserControl) Case 2 : ctrl = DirectCast(Me.FindControl("Default1"), UserControl) Case 3 : ctrl = DirectCast(Me.FindControl("ValuPro1"), UserControl) Case 4 : ctrl = DirectCast(Me.FindControl("ValuPro1"), UserControl) Case Else : ctrl = Nothing End Select

  • ASP.Net FormsAuthentication Redirect Loses the cookie between Redirect and Application_AuthenticateR

    - by Joel Etherton
    I have a FormsAuthentication cookie that is persistent and works independently in a development, test, and production environment. I have a user that can authenticate, the user object is created, the authentication cookie is added to the response: 'Custom object to grab the TLD from the url authCookie.Domain = myTicketModule.GetTopLevelDomain(Request.ServerVariables("HTTP_HOST")) FormsAuthentication.SetAuthCookie(authTicket.Name, False) Response.SetCookie(authCookie) The user gets processed a little bit to check for a first time login, security questions, etc, and is then redirected with the following tidbit: Session.Add("ForceRedirect", "/FirstTimeLogin.aspx") Response.Redirect("~/FirstTimeLogin.aspx", True) With a debug break, I can verify that the cookie collection holds both a cookie not related to authentication that I set for a different purpose and the formsauthentication cookie. Then the next step in the process occurs at the ApplicationAuthenticateRequest in the global.asax: Sub Application_AuthenticateRequest(ByVal sender As Object, ByVal e As EventArgs) Dim formsCookieName As String = myConfigurationManager.AppSettings("FormsCookieName") Dim authCookie As HttpCookie = Request.Cookies(formsCookieName) At this point, for this ONE user authCookie is nothing. I have 15,000 other users who are not impacted in this manner. However, for one user the cookie just vanishes without a trace. I've seen this before with w3wp.exe exceptions, state server exceptions and other IIS process related exceptions, but I'm getting no exceptions in the event log. w3wp.exe is not crashing, the state server has some timeouts but they appear unrelated (as verified by timestamps) and it only happens to this one user on this one domain (this code is used across 2 different TLDs with approximately 10 other subdomains). One avenue I'm investigating is that the cookie might just be too large. I would think that there would be a check for the size of the cookie going into the response, and I wouldn't think it would impact it this way. Any ideas why the request might dumping the cookie? NOTE: The secondary cookie I mentioned that I set also gets dumped (and it's very tiny). EDIT-NOTE: The session token is NOT lost when this happens. However, since the authentication cookie is lost, it is ignored and replaced on a subsequent login.

  • Using the Rijndael Object in VB.NET

    - by broke
    I'm trying out the Rijndael to generate an encrypted license string to use for our new software, so we know that our customers are using the same amount of apps that they paid for. I'm doing two things: Getting the users computer name. Adding a random number between 100 and 1000000000 I then combine the two, and use that as the license number(This probably will change in the final version, but I'm just doing something simple for demonstration purposes). Here is some sample codez: Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim generator As New Random Dim randomValue As Integer randomValue = generator.Next(100, 1000000000) ' Create a new Rijndael object to generate a key ' and initialization vector (IV). Dim RijndaelAlg As Rijndael = Rijndael.Create ' Create a string to encrypt. Dim sData As String = My.Computer.Name.ToString + randomValue.ToString Dim FileName As String = "C:\key.txt" ' Encrypt text to a file using the file name, key, and IV. EncryptTextToFile(sData, FileName, RijndaelAlg.Key, RijndaelAlg.IV) ' Decrypt the text from a file using the file name, key, and IV. Dim Final As String = DecryptTextFromFile(FileName, RijndaelAlg.Key, RijndaelAlg.IV) txtDecrypted.Text = Final End Sub That's my load event, but here is where the magic happens: Sub EncryptTextToFile(ByVal Data As String, ByVal FileName As String, ByVal Key() As Byte, ByVal IV() As Byte) Dim fStream As FileStream = File.Open(FileName, FileMode.OpenOrCreate) Dim RijndaelAlg As Rijndael = Rijndael.Create Dim cStream As New CryptoStream(fStream, _ RijndaelAlg.CreateEncryptor(Key, IV), _ CryptoStreamMode.Write) Dim sWriter As New StreamWriter(cStream) sWriter.WriteLine(Data) sWriter.Close() cStream.Close() fStream.Close() End Sub There is a couple things I don't understand. What if someone reads the text file and recognizes that it is Rijndael, and writes a VB or C# app that decrypts it? I don't really understand all of this code, so if you guys can help me out I will love you all forever. Thanks in advance
