  • ASP.NET: images broken when combining URL Rewriting, asp:ImageButton and html base tag

    - by Nick G
    Hi, I'm using URL Rewriting under ASP.NET 4 (using ISAPI_Rewrite) and I'm finding that that some of my images are not loading as .NET does not seem to understand I'm using an html BASE tag (pretty standard and essential when doing URL Rewriting): eg in my development environment I have: <base href='http://localhost/venuefinder/Website/'></base> and on my pages I have: <asp:ImageButton runat="server" ImageUrl="~/images/button.gif" /> On the home page of the site (http://localhost/venuefinder/Website/) this works fine, however on a page that uses URL rewriting, the image does not work: /venuefinder/Website/venues/ashton_gate_stadium/V18639/ ..as the browser is trying to load: http://localhost/images/buttons/search-button.gif instead of: http://localhost/venuefinder/Website/venues/images/buttons/search-button.gif This is happening because .NET is rendering the button as: src="../../../images/buttons/search-button.gif" ...which is incorrect. Is there any way I can correct this problem so that .NET renders the correct src attribute for the image? (without all the ../../../ etc)

  • ASP.NET MCV 2, re-use of SQL-Connection string

    - by cc0
    Hi, so I'm very very far from an expert on MVC or ASP.NET. I just want to make a few simple Controllers in C# at the moment, so I have the following question; Right now I have the connection string used by the controller, -inside- the controller itself. Which is kind of silly when there are multiple controllers using the same string. I'd like to be able to change the connection string in just one place and have it affect all controllers. Not knowing a lot about asp.net or the 'm' and 'v' part of MVC, what would be the best (and simplest) way of going about accomplishing just this? I'd appreciate any input on this, examples would be great too.

  • .NET Properties - Use Private Set or ReadOnly Property?

    - by tgxiii
    In what situation should I use a Private Set on a property versus making it a ReadOnly property? Take into consideration the two very simplistic examples below. First example: Public Class Person Private _name As String Public Property Name As String Get Return _name End Get Private Set(ByVal value As String) _name = value End Set End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo Me.Name = txtInfo.ToTitleCase(Me.Name) End Sub End Class // ---------- public class Person { private string _name; public string Name { get { return _name; } private set { _name = value; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; this.Name = txtInfo.ToTitleCase(this.Name); } } Second example: Public Class AnotherPerson Private _name As String Public ReadOnly Property Name As String Get Return _name End Get End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo _name = txtInfo.ToTitleCase(_name) End Sub End Class // --------------- public class AnotherPerson { private string _name; public string Name { get { return _name; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; _name = txtInfo.ToTitleCase(_name); } } They both yield the same results. Is this a situation where there's no right and wrong, and it's just a matter of preference?

  • Configuring Multiple ASP.NET MVC Sites To Use a Single Database For Authentication/Membership

    - by Maxim Z.
    Is it possible for two or more ASP.NET MVC sites to use a single SQL Server database for authentication and other things? Here's how I'm thinking of setting it up: I will combine the current database of each site into one single database, prefixing the tables with the name of the site they belong to. I currently have authentication tables generated by the asp.net_regsql.exe utility. How should I combine those tables? I'm guessing that the way to do it is to somehow set the "application_id" column in those tables... Thanks in advance.

  • What's missing in ASP.NET MVC?

    - by LukaszW.pl
    Hello programmers, I think there are not many people who don't think that ASP.NET MVC is one of the greatest technologies Microsoft gave us. It gives full control over the rendered HTML, provides separation of concerns and suits to stateless nature of web. Next versions of framework gaves us new features and tools and it's great, but... what solutions should Microsoft include in new versions of framework? What are biggest gaps in comparison with another web frameworks like PHP or Ruby? What could improve developers productivity? What's missing in ASP.NET MVC?

  • ASP.NET 4.5 Bundling in Debug Mode - Stale Resources

    - by RPM1984
    Is there any way we can make the ASP.NET 4.5 Bundling functionality generate GUID's as part of the querystring when running in debug mode (e.g bundling turned OFF). The problem is when developing locally, the scripts/CSS files are generated like this: <script type="text/javascript" src="/Content/Scripts/myscript.js" /> So if i change that file, i need to do a hard-refresh (sometimes a few times) to get the file to be picked up by the browser - annoying. Is there any way we can make it render out like this: <script type="text/javascript" src="/Content/Scripts/myscript.js?v=x" /> Where x is a GUID (e.g always unique). Ideas? I'm on ASP.NET MVC 4.

  • Is it possible to share session state between asp.net aspx page making a call to an asp.net webservi

    - by Greg Balajewicz
    My Situation: I have 1 asp.net application with both aspx pages AND webservices I make calls (using ajax) to the webservice from an aspx page - all within the same asp.net application! Here is my problem/question Is there any way to share the session state? I.e. - the aspx page has a sessionID and the state is being maintained. When the call to the webservice is made, is there a way to automatically send the seesionID to the webservice and then be able to access the same session state from the webservice? -- That would greatly simplify my work! :) Many thanks for your ideas!!

  • ASP.Net MVC2 (RTM) breaks response filtering - "Filtering is not allowed"

    - by womp
    I've just done a test run of upgrading a project to ASP.Net MVC 2 (RTM) in anticipation of the full official .Net 4.0 release coming later this month. Our application is using a minimizer for our CSS and javascript. To do so, it is making use of the HttpResponse.Filter property to set a custom filter. With the upgrade, the setter for this property is throwing an HttpException saying "Filtering is not allowed." Looking that the HttpResponse.Filter property in reflector shows this: set { if (!this.UsingHttpWriter) { throw new HttpException(SR.GetString("Filtering_not_allowed")); } ... private bool UsingHttpWriter { get { return ((this._httpWriter != null) && (this._writer == this._httpWriter)); } } Clearly something has changed in the way the HttpResponse is writing to the output stream in MVC2. Does anyone know what the change is, or at least a workaround for this? EDIT: This seems pretty radical. Some further investigation shows that ASP.Net MVC 2 RTM is using a System.Web.Mvc.ViewPage.SwitchWriter as the Output property of an HttpResponse, whereas MVC 1 was using a plain old HttpWriter. That explains why the exception is being thrown. But that doesn't explain why they've chosen to completely break this functionality. This thread seems to indicate that this is just temporary... but this makes me pretty nervous... this is the RTM after all. Any further comments appreciated on this.

  • Support for nested model and class validation with ASP.NET MVC 2.0

    - by Diep-Vriezer
    I'm trying to validate a model containing other objects with validation rules using the System.ComponentModel.DataAnnotations attributes was hoping the default MVC implementation would suffice: var obj = js.Deserialize(json, objectInfo.ObjectType); if(!TryValidateModel(obj)) { // Handle failed model validation. } The object is composed of primitive types but also contains other classes which also use DataAnnotications. Like so: public class Entry { [Required] public Person Subscriber { get; set; } [Required] public String Company { get; set; } } public class Person { public String FirstName { get; set;} [Required] public String Surname { get; set; } } The problem is that the ASP.NET MVC validation only goes down 1 level and only evaluates the properties of the top level class, as can be read on digitallycreated.net/Blog/54/deep-inside-asp.net-mvc-2-model-metadata-and-validation. Does anyone know an elegant solution to this? I've tried xVal, but they seem to use a non-recursive pattern (http://blog.stevensanderson.com/2009/01/10/xval-a-validation-framework-for-aspnet-mvc/). Someone must have run into this problem before right? Nesting objects in your model doesn't seem so weird if you're designing a web service.

  • New Location for .NET 4 GAC

    - by Ricardo Peres
    .NET 4 newcomers may have realised that the old GAC location (%WINDIR%\Assembly) does not contain .NET 4 global assembly cache assemblies. Indeed, they have moved to %WINDIR%\Microsoft.NET\Assembly. It is worth noting that this folder does not use the shell extension that the older one uses, which prevents us from directly looking at the folder's contents, which, IMO, is nice (I mean, the new behavior). The old folder continues to host pre-.NET 4 assemblies.

  • Partial view links not working in Fire Fox

    - by user329540
    I have a MVC4 asp.net application, I have two layouts a main layout for the main page and a second layout for the nested pages. The problem I have is with the second layout, on this layout I call a partial view which has my navigation links. In IE the navigation menu displays fine and when each item is clicked it navigates as expected. However in FF when the page renders the navigation bar is displayed but it has no 'click functionality' if you will its as if its simply text. My layout of nested page: <header> <img src="../../Images/fronttop.png" id="nestedPageheader" alt="Background Img"/> <div class="content-wrapper"> <section > <nav> <div id="navcontainer"> </div> </nav> </section> <div> </header> The script to retreive partial view and information for dynamic links on layout page. <script type="text/javascript"> var menuLoaded = false; $(document).ready(function () { if($('#navcontainer')[0].innerHTML.trim() == "") { $.ajax({ url: "@Url.Content("~/Home/MenuLayout")", type: "GET", success: function (response, status, xhr) { var nvContainer = $('#navcontainer'); nvContainer.html(response); menuLoaded = true; }, error: function (XMLHttpRequest, textStatus, errorThrown) { var nvContainer = $('#navcontainer'); nvContainer.html(errorThrown); } }); } }); </script> May partial view: @model Mscl.OpCost.Web.Models.stuffmodel <div class="menu"> <ul> <li><a>@Html.ActionLink("Home", "Index", "Home")</a></li> <li><a>@Html.ActionLink("some stuff", "stuffs", "stuff")</a></li> <li> <h5><a><span>somestuff</span></a></h5> <ul> <li><a>stuffs1s</a> <ul> @foreach (var image in Model.stuffs.Where(g => g.Grouping == 1)) { <li> <a>@Html.ActionLink(image.Title, "stuffs", "stuff", new { Id = image.CategoryId }, null)</a> </li> } </ul> </li> </ul> </il> </ul> </div> I need to know why this works fine in IE but why its not working in FF(all versions). Any assistance would be appreciated.

  • How to publish an ASP.NET MVC website

    - by Luke Puplett
    Hello -- I've a site that I'd like to publish to a co-located live server. I'm finding this simple task quite hard. My problems begin with the Web Deploy tool (1.1) giving me a 401 Unauthorized as the adminstrator because port :8172 comes up in the errors and this port is blocked - but the documentation says "The default ListenURL is http://+:80/MsDeployAgentService"! I'm loathe to open another port and I've little patience these days so I thought bu66er it, I'll create a Web Deploy package and import it into IIS on the server over RDP. I notice first that Visual Studio doesn't use a dialog box to gather settings, or use my Publish profiles but seems to use a tab in the project properties, although I think these are ignored when importing the package anyway? I'm now sitting in the import wizard with Application Path and Connection String. I've cleared the conn string as I think this is for some ASP stuff I don't use but when I enter nothing in the Application Path, the wizard barks at me saying that basically I'm a weirdo because most people publish to folders beneath the root site. Now, I want my site to be site.com/Home/About and not site.com/subfolder/Home/About and I think being an MVC routed site that a subfolder will introduce other headaches. Should I go ahead and use the root? Finally, I also want to publish a web service to www.site.com/services/soap which I think IIS can handle. While typing this question, Amazon have delivered my IIS 7 Resource Kit, and I've been scouring the internet but actually I'm getting more confused. Comment here seems to show consensus opinion that Publish isn't for production sites and that real men roll their own. http://stackoverflow.com/questions/260525/asp-net-website-publish-vs-web-deployment-project ...I guess this was pre- Web Deployment Tool era? I'm going to experiment on a spare box for now but any assistance is welcome. Luke

  • Friend WithEvents in VB vs private in C#

    - by serhio
    Hello, friends Who knows, why in vb.net WinForm projects the designer by default use the Friend WithEvents attributes and in C# - private ones. By ex, in a form.designer. .cs private Label Label1; .vb Friend WithEvents Label1 as Label; For WithEvents is more or less clear(for using Handles, apparently). But why Friend in VB and private in C#... Thanks.

  • Multi-level inheritance with Implements on properties in VB.NET vs C#

    - by Ben McCormack
    Let's say I have 2 interfaces defined like so: public interface ISkuItem { public string SKU { get; set; } } public interface ICartItem : ISkuItem { public int Quantity { get; set; } public bool IsDiscountable { get; set; } } When I go to implement the interface in C#, VS produces the following templated code: public class CartItem : ICartItem { #region ICartItem Members public int Quantity { get {...} set {...} } public bool IsDiscountable { get {...} set {...} } #endregion #region ISkuItem Members public string SKU { get {...} set {...} } #endregion } In VB.NET, the same class is built out like so: Public Class CartItem Implements ICartItem Public Property IsDiscountable As Boolean Implements ICartItem.IsDiscountable 'GET SET' End Property Public Property Quantity As Integer Implements ICartItem.Quantity 'GET SET' End Property Public Property SKU As String Implements ISkuItem.SKU 'GET SET' End Property End Class VB.NET explicitly requires you to add Implements IInterfaceName.PropertyName after each property that gets implemented whereas C# simply uses regions to indicate which properties and methods belong to the interface. Interestingly in VB.NET, on the SKU property, I can specify either Implements ISkuItem.SKU or Implements ICartItem.SKU. Although the template built by VS defaults to ISkuItem, I can also specify ICartItem if I want. Oddly, because C# only uses regions to block out inherited properties, it seems that I can't explicitly specify the implementing interface of SKU in C# like I can in VB.NET. My question is: Is there any importance behind being able to specify one interface or another to implement properites in VB.NET, and if so, is there a way to mimic this functionality in C#?

  • Using C# and VB.NET in one solution

    - by Younes
    I'm busy on a small project to convert an Access2003 db to .NET. I am trying to integrate my functionality in an excisting project that is being used for Administration of some kind. The code in this project is vb.net. I started by setting up my Data Access Layer, which seems to work fine. I can make new web pages that acces the data I need. However when i start to use class files to set up my Business Logic Layer i can't build my project when using C# instead of VB. I Dislike VB and like to program in C# as i know the syntax alot better etc. Is it possible to program using C# knowing that VB.NET was the language chosen to buold the entire project on? If not, what will be the smartest way to integrate my module into the project using my favorite programming language? (Make a project and reference to the dll?)

  • Two asp.net applications to use the same membership tables - specifically user login data

    - by Lk
    HI, I have created a asp.net solution with two applications. They bothe use the same database which is setup with .net membership and roles. Application 1 uses the membership for sauthentication to an administration area - this works fine. Application 2 - has a different applicationID to App1. I want to be able to use the existing user account to manage App2's authentication needs. How is this best achieved? Do I just match App2 appliactionID to App1's or is there another way? Many Thanks, Lk

  • Drop Down Box and other stuff in ASP.NET with VB.NET (VS 2008)

    - by typoknig
    Hi all, I am trying to polish up a program a program that I have converted from a Windows Form in to an ASP.NET Web Application. I have several questions: 1.) I have a drop down box where users can select their variables, but users can also enter their variables manually into various text fields. What I want is for the drop down box to show a string like "Choose Variables" when ever the user enters their variables manually. I want this to happen without having to reload the page. 2.) In the Windows Form version of this application I had a RichTextBox that populated with data (line by line) after a calculation was made. I used "AppendText" in my Windows Form, but that is not available in ASP.NET, and neither is the RichTextBox. I am open to suggestions here, I tried to use just a text box but that isn't working right. 3.) In my Windows Form application I was using "KeyPress" events to prevent incorrect characters from being entered into the text fields. My code for these events looked similar to this: Private Sub TextBox_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox.KeyPress If (e.KeyChar < "0" OrElse e.KeyChar > "9") AndAlso e.KeyChar <> ControlChars.Back AndAlso e.KeyChar <> "." Then e.Handled = True End If End Sub How can I make this work again... also without reloading the page. 4.) This is not a major issue, but I would like all of the text to be selected when the cursor enters a field. In my Windows Form application I used "SelectAll", but again, that is not available in ASP.NET Thanks in advanced.

  • Handle Enter Key on Website (ASP and VB)

    - by Andrew
    So I have a website with multiple asp controls. When I press enter inside by login form, the search function runs because it's the first thing found on the page. How would I handle the enter button so that when the active textbox is for the login form, the loginbutton code actually runs rather than the searchbutton. One last problem is that the login controls are inside a loginview so the hierarchy shows that the asp:textbox and asp:button for logging in are inside 3 tags like so: <loginview> <login> <logintemplate> //controls are here. </logintemplate> </login> Just a note that all controls are asp and that all code is prefered in VB. Thanks

  • ASP.NET MVC (VB) error when publishing to test server

    - by Colin
    I have an ASP.NET MVC project that works fine on my local machine (no build errors, server errors or anything). However, when I publish the project to a test server, I get an "Object reference not set to an instance of an object" error on a For Each I have in my view. I have a function within a model that returns a DataRowCollection. I'm calling that function in my controller and passing the DataRowCollection to my View, which then iterates over the rows and displays the necessary information: In the Controller I have: Function Index() As ActionResult Dim MyModel As New Model ViewData("MyDataRowCollection") = MyModel.GetDataRowCollection() Return View() End Function And then in the View, which is throwing the error: <%@ Page Language="VB" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server"> My Page Title </asp:Content> <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <% For Each MyDataRow In ViewData("MyDataRowCollection") ' do stuff with each MyDataRow Next %> I'm pretty new to ASP.NET MVC so I'm sure there might be a better way to do what I'm doing (I'd be happy to hear if there is), but my main concern is why this works fine on my local machine but throws an error on the For Each on the test server? Please let me know if I can clarify any of the above, and thanks in advance for any information.

  • Top 5 reasons for using ASP.NET MVC 2 rather than ASP.NET MVC 1

    - by Richard Ev
    I've been using ASP.NET MVC 1 for a while now, and am keen to take advantage of the improvements in MVC 2. Things like validation seem greatly improved, and strongly-typed HTML helper methods look great. So, for those of you who have real-world practical experience of using ASP.NET MVC 1 and are now using MVC 2, what are your top 5 reasons for using MVC 2?
