  • Unable to install .NET Framework 3.5 to my XP machine

    - by CptanPanic
    I have an application that requires .NET 3.5, but I can't install it. The installer quits saying "it has encoutered a problem during setup. If I look at some of the error logs in the tmp directory I see. Error occurred while initializing fusion. It seems that I have 2.0 SP1 installed. Any ideas how I can get it to work?

  • Using ASP.NET Session for Lifetime Management (Unity)

    - by Sigray
    I am considering using Unity to manage the lifetime of a custom user class instance. I am planning on extending the LifetimeManager with a custom ASP.NET session manager. What I want to be able to do is store and retrieve the currently logged in user object from my custom classes, and have Unity get the instance of User from the session object in ASP.NET, or (when in a Win32 project) retrieve it statically or from the current thread. So far my best solution is to create a static instance of my Unity container on startup, and use the Resolve method to get my User object from each of my classes. However, this seems to create a dependency on the unity container in my other classes. What is the more "Unity" way of accomplishing this goal? I would like to be able to read/replace the current User instance from any class.

  • Prevent painting of .NET form while form is loading?

    - by dvcolgan
    Is there a way to turn off all visual updates to a .NET form while I am manipulating it? When my program first loads, for example, I set the tab control to the tab that was last open. The user can see the program switching tabs. I have looked into SuspendLayout and ResumeLayout, but either I don't understand what they are doing, or I am not using them correctly, because they don't seem to have any effect. Someone told me that there used to be a way to turn off paint events in VB 6. Does this still exist in .NET?

  • IE7 Times Out Debugging ASP.Net Page

    - by Eric J.
    My issue is similar to ASP.NET Debugging Timing out with IIS except that I'm using the built-in ASP.Net Development Server with VS 2010. If I pause for more than about 10 seconds in the debugger, IE7 "disconnects" from the web server with the error message Internet Explorer cannot display the webpage However, unlike in the similar question, the debugger is still running. If I refresh the browser it will post that refresh to the server and I can debug the page from the top again. Is it possible to configure things so that IE7 waits (much) longer before giving up? If it makes a difference, I'm launching IE using the "Start external program" option and passing a localhost URL as the command line argument (since Chrome is my default browser). I also specify a specific port.

  • Using Report (Reporting Services) parameter values in ASP.NET page

    - by noup
    I have a report (Reporting Services) integrated into an ASP.NET that shows dropdownlists to select report parameter values. The dropdownlists are populated using direct database selects, though I see the report RDL files do contain the paramter values and datasets as defined in the report designer. Is it possible to obtain the report parameters "available values" in ASP.NET to populate the dropdownlists? This would avoid some code duplication. Update If the parameter doesn't use a query for available values, the following works: foreach (ValidValue value in this.ReportViewerControl.ServerReport.GetParameters()["myParameter"].ValidValues) { this.DropDownListControl.Items.Add(new ListItem(value.Label, value.Value)); } Still haven't found a way to access report datasets though...

  • JavaScript and ASP.NET - Cookies with Key / Value Pairs

    - by user208662
    Hello, This question mixes client-side scripting with server-side parsing. In some cases, I'm writing a cookie to the user's browser using the document.cookie property. In other cases, I'm writing the same cookie to the user's browser through the ASP.NET Response object. When I'm writing the HttpCookie on the server-side, I am using the Values collection (http://msdn.microsoft.com/en-US/library/system.web.httpcookie.values%28v=VS.80%29.aspx) to store key/value pairs in the cookie. I would also like to be able to write key-value pairs to the cookie through JavaScript. How do I create cookies with Key/Value pairs via JavaScript that ASP.NET can parse? Thank you!

  • ASP.NET Forms automation/serialization/binding

    - by creo
    I need to implement many forms in ASP.NET application (for IRS mostly). There are will be a lot of standard controls for each form (textboxes, dropdowns, checkboxes, radio). And business entity assigned to each. What's the best solution to automate this process? I need to: Have layout stored in DB (in XML). Layout must support several columns, tabbed interface Automatically bind business object values to the form Automatically read form values and write to business object Must support automatic validation Some basic workflows support would be good I used to work with TFS and saw how they implemented WorkItem templates (.wit files). In general this is all I need. But what framework did they build it on? How can I utilize this solution? I know about Dynamic Data only: http://www.asp.net/dynamicdata

  • ASP.NET Controls Not Recognized

    - by Liam
    I just installed the release version of Visual Studio 2010, and it looks like there's something wrong with the standard ASP.NET server controls. When I create a basic server control, such as a TextBox, the editor underlines it in green and says (I also get no intellisense for ASP.NET controls): Element 'TextBox' is not a known element. This can occur if there is a compilation error in the Web site, or the Web.config file is missing. The web site builds fine, and the Web.config file is not missing: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="false" targetFramework="4.0" /> </system.web> </configuration> The controls work just fine in the code-behind, and they function correctly when I run the site. Is there some configuration problem here?

  • ASP.Net Checkbox Doesn't Allow Setting Visible to True

    - by Shawn Steward
    I'm working on an old web application in Visual Studio .Net 2003 (yeeich) and I'm having an issue with a Checkbox that will not set the Visibility to True. It's declared as such: Protected WithEvents chkTraining As System.Web.UI.WebControls.CheckBox and <asp:CheckBox id="chkTraining" runat="server" Visible="False"></asp:CheckBox> When I am debugging through the line that has: chkTraining.Visible = True it goes past it fine, but as I check this value on the very next line, chkTraining.Visible = False. What could possibly be going on here? There's no events firing off or anything else going on... this really is throwing me for a loop. Thanks for your help.

  • Why does adding a reference to project targeting .NET Framework 4.0 fail?

    - by Malcolm Post
    We have two projects that are both class libraries. Project 1 is a VS 2008 project and targets the .NET Framework 3.5. Project 2 is a VS 2010 (release candidate) project that targets the .NET Framework 4.0. When I try to add a reference to Project 2 in Project 1, it fails with a less than informative error message. I know that if I change the target Framework for Project 2 to 3.5, then adding the reference will work. My question is, if I don't change the target frameworks, but convert Project 1 to VS 2010, will the referencing work? Stated another way, is there some inherent incompatiblity between class libraries targeting different framework versions, or is it failing for me because VS 2008 doesn't know about the 4.0 framework?

  • ASP.NET UserControl not defined?

    - by BryanG
    I've just inherited an app that utilizes usercontrols in a couple ways which I'm not too familiar with. The problem I have right now is that when I attempt to publish this code base, I get a few errors which boil down to where some referenced usercontrols are not defined. Here's an example of one line: Private clientControl As New ASP.usercontrols_clientcontrol_ascx This is a tab strip usercontrol which references other usercontrols to dynamically create the tabs. Now, on the surface I get what is going on here...but the compiler is not accepting this. This tab strip usercontrol is in the root of the project, and the other usercontrols are in a sub folder. error BC30002: Type 'ASP.usercontrols_clientcontrol_ascx' is not defined. I'm sure this is 101 stuff here, but the build works and the publish fails. Any direction would be appreciated.

  • ASP.Net WebSite Membership AND C# Windows Form Membership

    - by user1638362
    This is not real, it's just a project i'm working on I've created a Hotel Management system in C# WindowsForm, it allows staff members to Add/Edit/Update Rooms,Reservation and Customers etc. Along side this Windows-form i'm creating an ASP.net WebSite where customers should be able to register and reserve rooms online. I've come to the point where i need to create some-type of membership method for this website which should correspond to the membership of the windows form. However i'm not sure what method of membership would be best suited for this, i have looked into the asp.net membership, it's what i want however it creates it's own schema and i don't know how i can relate the information to my customers table and c#windows form. I would ideally like it to resemble a real-life situation as much as possible anyway, am i going about this the wrong way? in terms of the c# windows-form what other technology would a business use to manage a system like this where they can add/edit/update there system and have a website which relates. What are my options here?

  • Online webcam chat. Free server and easy-to-implement client?

    - by Oskar Kjellin
    I have a client requesting that his users can use their webcams to talk to each other. From what I've understood the main thing to use for this is Flash. However as I have not written flash I would like to have something really easy to implement. Of course preferrably free (or trial). The idea of this is that everything but the chat alone is in .net. So the users will not use flash until they are actaully going to talk to each other. So there is no use for rooms here. I've been looking into silverlight some as well. But it seems like silverlight does not offer streaming between users..? I know this question has been asked many times here. But I could not find a suitable answer which is why I post a new question.

  • ASP.net Usercontrol caching viewstate across users?

    - by Jason
    I have a usercontrol with asp:textbox controls on it that also performs postbacks. If two users, who are both identified by a different session variable, postback the page within the same second, one user will see the other user's viewstate values in the text boxes. I have validated that this happens by setting a textbox, a session variable, and a cookie to the same value (the same value that identifies the user) and writing to the log when all three don't match. The text box's value is the one that is logged as the other user's value. ASP.net 3.5, IIS 6 Has anyone experienced this issue.

  • generating an asp.net web application dll requirement list

    - by Oren Mazor
    I'm trying to set up a web app (32bit on ii7/win7, 32bit setting is enabled, everything is compiled to x86, using vs2008), but there's clearly some dll module loading issue happening. I've been watching procmon and fusion logs but I'm not seeing the name of the missing dll. I'm a complete newbie to asp.net (but fairly heavy experience on other platforms). I know I can call depends.exe on a binary to see what the dependancies are, but how do I do it for asp.net? specifically, is it possible to get a list of the dlls that iis7 loads for my application?

  • asp.net Can I force every page to inherit from a base page? Also should some of this logic be in my master page?

    - by Bex
    Hi! I have a web app that has a base page. Each page needs to inherit from this base page as it contains properties they all need as well as dealing with the login rights. My base page has some properties, eg: IsRole1, IsRole2, currentUserID, Role1Allowed, Role2Allowed. On the init of each page I set the properties "Role1Allowed" and "Role2Allowed" Private Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init Role1Allowed = True Role2Allowed= False End Sub The basepage then decides if the user needs redirecting. 'Sample code so not exactly what is going to be, bug gives the idea Protected Overridable Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) If Role1Allowed And Not Role1 Then 'Redirect somewhere End If End Sub The page then must override this pageload if they need anything else in it, but making sure they call the base pageload first. Protected Overrides Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load MyBase.Page_Load(sender, e) If Not IsPostBack Then BindGrid() End If End Sub The other properties (IsRole1, IsRole, currentUserID) are also accessible by the page so it can be decided if certain things need doing based on the user. (I hope this makes sense) Ok so I have 2 questions Should this functionality be in the base page or should it somehow be in the master, and if so how would I get access to all the properties if it was? As there are multiple people working on this project and creating pages some are forgetting to inherit from this basepage, or call the base pageload when overriding it. Is there any way to force them to do this? Thanks for any help. bex

  • ASP.NET single quotes are converted to &#39;

    - by Monty
    Note: Most probably this will be a double question, but since I haven't found a clear answer, I'm asking it anyway. In ASP.NET I'd like to add some JavaScript to the onclick event of a CheckBox. I've simplified the case to this: <asp:CheckBox ID="TestCheckBox" runat="server" onclick="alert('test');" Text="Test" /> The resulting HTML is as follows: <input id="MainContainer_TestCheckBox" type="checkbox" name="ctl00$MainContainer$TestCheckBox" onclick="alert(&#39;test&#39;);" /><label for="MainContainer_TestCheckBox">Test</label> What particularly bothers me is that a single quote 'automatically' gets converted into '&#39;'. If I omit the onclick in the markup and assign it in Page_Load, the exact same results show in the HTML. protected void Page_Load(object sender, EventArgs e) { this.TestCheckBox.Attributes["onclick"] = "alert('test');"; } Anyone got a clue about what's happening? Or how to fix/ avoid it?

  • ASP.NET calendar drawing control

    - by BCS
    I want to make a simple ASP.NET page that draws a months from a calendar and highlights given dates. (I'm not looking for a date picker.) What I have is a list of DateTime values and I need to display them a a nice way. Given that I'm a total beginner with ASP, simpler really is better. (I'd rather not, I'm willing to hack together something with StringBuilder and <table> if it's easier). p.s. I have no budget, so non-free controls will only be of use to other readers.

  • ASP.NET Treeview Control not expanding on click

    - by Scott Vercuski
    I having an issue with the ASP.NET Treeview control. I create the treeview just fine but the nodes will not expand or collapse. I see there is a javascript error but it is for line 1 character 0 of the webpage, there is nothing at line 1 character 0. I am using the ASP:Treeview control in conjunction with the Telerik controls, but I'm not sure if that is an issue. I saw there was a similar question here but the answer is not pertinent to my site. Has anyone run into this issue before? I've tried searching Google and tried a number of proposed solutions but so far none have worked. Thank you,
