• Can't get NUnit to work in Visual Web Develper 2010 express.

  - by UkraineTrain

  First off I was wondering whether it's possible to implement a functionality with Nunit where each time a project is created in Visual Web Developer 2010 I get a dialog asking whether I want to create a unit test project for current application like I saw it happen in the older versions of Visual Web Developer. I've tried just about everything to get NUnit 2.5.5 to work in Visual Web Developer 2010. For example, in nunit.exe.config I added under configuration <startup> <requiredRuntime version="v4.0.30319" /> </startup> and under runtime: <loadFromRemoteSources enabled="true" /> I then tried to launch nunit-console.exe in order to specify in the command line the option /framework=net-4.0, but the console would appear and instantly disappear. It didn't help when I tried running it as an administrator. I've also tried using Nunit as an external tool inside the Visual Web Developer by creating a toolbar as described in the following link: http://www.marthijnvandenheuvel.com/2010/06/09/using-nunit-in-visual-studio-2010/. It shows up as an icon in the toolbar. I ran my project called ToyStore and then clicked Nunit icon in order to launch it and it gave me a "System.IO.FileNotFoundException:Assembly not found:ToyStore.dll". So, needless to say, I'm pretty lost and don't know what to do and would greatly appreciate any help in getting Nunit to work.

• How can I make an AJAX link work once it is moved out of the iFrame?

  - by KcYxA

  Hi, I am using an iFrame with a form that return some content with an AJAX link. I am then moving the returned content out of the iFrame into the main page. However, then the ajax link does not work and the error "Element is null" is created once the link is clicked. How can I move content from the iFrame and still have the AJAX link working? Here's the code returned by the iFrame: <span id="top"> <a id="link8" onclick=" event.returnValue = false; return false;" href="/item_pictures/delete/7"> <img src="/img/delete.bmp"/> </a> <script type="text/javascript"> parent.Event.observe('link8', 'click', function(event) { new Ajax.Updater('top','/item_pictures/delete/3', { asynchronous:true, evalScripts:true, onCreate:function(request, xhr) { document.getElementById("top").innerHTML = "<img src=\"/img/spinner_small.gif\">"; }, requestHeaders:['X-Update', 'top'] }) }, false); </script> </span>

• asp:CustomValidator / OnServerValidate

  - by Neil

  I have a CheckBoxList that I am trying to validate that at least one of the checkboxes is checked. Markup: <asp:CustomValidator ID="RequiredFieldValidator8" ValidationGroup="EditArticle" runat="server" ErrorMessage="At least one Category is required." OnServerValidate="topic_ServerValidate" /> <asp:CheckBoxList id="checkboxlistCategories" runat="server"></asp:CheckBoxList> Code-behind: protected void topic_ServerValidate(object source, ServerValidateEventArgs args) { int i = 0; foreach (ListItem item in checkboxlistCategories.Items) { if (item.Selected == true) i = i + 1; } if (i == 0) args.IsValid = false; else args.IsValid = true; } If I add ControlToValidate="checkboxlistCategories" in the CustomValidator control, it blows up! Am I missing something? Thanks in advance.

• How to complie x64 asp.net website?

  - by Eran Betzalel

  I'm trying to compile (using Visual Studio) an ASP.Net website with the Chilkat library. The compilation fails due to this error: Could not load file or assembly 'ChilkatDotNet2, Version=9.0.8.0, Culture=neutral, PublicKeyToken=eb5fc1fc52ef09bd' or one of its dependencies. An attempt was made to load a program with an incorrect format. I've been told that this error occurs because of platform noncompliance. The weird thing is that although the compilation fails, the site works once accessed from a browser. My theory is that the IIS compilation uses csc.exe compiler from the Framework64 (64 bit) folder while the Visual Studio uses csc.exe compiler from the Framework (32 bit) folder. If this is acually it, how can I configure my Visual studio to run with the 64 bit compiler for ASP.Net sites? This is my current development configuration: Windows 7 (x64). Visual Studio 2008 Pro (x86 of course...). Chilkat library (x64) IIS/Asp.net (x64).

• How to Track F5/Refresh in ASP.Net

  - by Everest

  I am using VS 2005, C# 2, ASP.Net 2.0 I am unable to find out how to track that user pressed F5/Ctrl+F5/ Open a new Window(Ctrl + N) in ASP.Net. I know that there is a Page.IsPostBack property, which tells that a page is loaded in response to an action taken by user. I am just curious to know, that why isn't there a property as IsRefresh or Page.IsRefresh in ASP.Net, which will return true, whenever user takes any of the above actions. Is there a way to know this? Actually my problem is that i have a DLL using which all of my aspx pages are inherited, I have to insert some values in a table whenever the page is opened for the first time that's it, if user just opens the page or do not take any action, an entry should be inserted into the database, but as far as I have tried, I controlled it anyhow using the Page.IsPostBack property, but I got stuck in the refresh case, as it is inserting records unconditionally.

• How to style an asp.net menu with CSS

  - by md1337

  I'm in the process of styling an asp.net menu and I'm trying to understand the meaning of the StaticSelectedStyle-CssClass and StaticHoverStyle-CssClass parameters. My understanding is that the styles defined with these parameters are applied as CSS classes to the relevant elements, whenever needed. So I created my menu as follows: <asp:Menu ID="NavigationMenu" DataSourceID="NavigationSiteMapDataSource" StaticMenuStyle-CssClass="StaticMenuStyle" StaticMenuItemStyle-CssClass="StaticMenuItemStyle" StaticSelectedStyle-CssClass="StaticSelectedStyle" StaticHoverStyle-CssClass="StaticHoverStyle" Orientation="Horizontal" MaximumDynamicDisplayLevels="0" runat="server"> </asp:Menu> It works for StaticMenuStyle-CssClass and StaticMenuStyle-CssClass (the classes are applied to the relevant elements), but StaticSelectedStyle-CssClass and StaticHoverStyle-CssClass are not applied, regardless of the selected or hover status of an element. What am I supposed to do to make this work? Thanks.

• Concatenating text in an ASP.NET localized label

  - by James B

  Trying to localize text in ASP.NET labels... want to add a ':' after the localized text. I could just add the ':' to the localized text in the resource file, but that seems silly... there should be an easy way to do this. <asp:Label id="RoleTypeLabel" runat="server" Text='<%$ Resources: GS3, RoleTypeLabel %>:' AssociatedControlID="RoleTypeDropDown"></asp:Label> (note the ':' at the end of Text='...') Of course, this doesn't work... and neither does anything I can think of to concatenate a ':' onto the end of the localized text. Anyone know how to do it? TIA, James

• Microsoft.Biztalk.explorerom.dll reference in asp.net application resulting system.nullreferenceexce

  - by sheetal.oza

  Hi, I have a asp.net application in order to start/stop applications and ports of Biztalk server 2006 r2. I have used "Microsoft.Biztalk.explorerom.dll (C:/Program Files/Biztalk Server 2006/Developer tool) " to achieve this. This is working fine on development machine since biz talk server is installed on local machine. But in the production environment (asp.net web server ,windows 2003 and iis 6.0)...this give System.nullreferenceexception (object reference not set..) at BtsCatalogExplorer explorer = (BtsCatalogExplorer)myGroup.CreateInstance(typeof(BtsCatalogExplorer)) my biztalk server and sql server are on two different box. In my setup (asp.net web application)..adding Microsoft.Biztalk.explorerom.dll and Microsoft.Biztalk.Applicationdeployment.engine.dll to GAC. But still no luck. Do i need to install biz talk server on my local machine even though I am connecting to different biz talk server?? And help is appreciated...

• Visual Studio Web Application edit source while running like in Tomcat\Eclipse\Java

  - by Bryan Migliorisi

  In an ASP.NET Web Site project, I've always been able to make changes to the underlying C# code and simply refresh the page in the browser and my changes would be there instantly. I can do the same thing when working with Java and Eclipse - edit my Java source and refresh the page and my changes are there. I cannot do this in ASP.NET MVC though and it is a real downer - I have to stop the running process and make my changes, and then restart debugging. This is a huge waste of time. Am I doing it wrong? What is the best approach to ASP.NET MVC development?

• Why does jQuery.ajax() add a parameter to the url?

  - by FK82

  Hi, I have a data fetching method that uses jQuery.ajax() to fetch xml files. /* */data: function() { /* debug */try { var url = arguments[0] ; var type = arguments[1] ; var scope = arguments[2] ; var callback = arguments[3] ; var self = this ; if(this.cache[url]) { callback(this.cache[url]) ; } else if(!this.cache[url]) { $.ajax({ type: "GET" , url: url , dataType: type , cache: false , success: function(data) { if(type == "text/xml") { var myJson = AUX.json ; var jsonString = myJson.build(data,scope,null) ; var jsonObject = $.parseJSON(jsonString) ; self.cache[url] = jsonObject ; callback(url) ; } else if(type == "json") { self.cache[url] = data ; callback(url) ; } } , error: function() { throw "Ajax call failed." ; } }) ; } /* debug */} catch(e) { /* debug */ alert("- caller: signTutor.data\n- " + e) ; /* debug */} } , My problem is: jQuery somehow adds a parameter (?_=1272708280072) to the url if there are escaped (hexadecimal notation) or unescaped utf-8 characters outside of the ASCII range -- i believe -- in the file name. It all works well if the file name does not contain characters in that range. Type is set to xml so there should not be a confusion of types. Headers of the xml files are also set adequately. I can see from the console that jQuery throws an error, but I'm not sure as to where the problem really is. Probably a problem with file name formatting, but I did not find any resources on the web as to AJAX file name specifications. Any ideas? Thanks for you help!

• Sharing ASP.NET State databases between multiple apps

  - by MikeWyatt

  Is it better for a collection of ASP.NET web apps to share the same session database, or should each one have its own? If there is no significant difference, having a single database would be preferable due to easier maintenance. Background My team has an assortment of ASP.NET web apps, all written in either Monorail 1.1 or ASP.NET MVC 1.0. Each app currently uses a dedicated session state database. I'm working on adding a new site to that list, and am debating whether I should create another new session database, or just share an existing one with another app.

• uploading multiple files from client to server with asp.net

  - by Maestro1024

  uploading multiple files from client to server with asp.net I have been looking at the asp.net upload control but that is for one file (unless someone knows a better way to do it). http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload.aspx For what I want to do I don't even really need a browse. I know the files off of the client are at a certain location. Is it possible to create a collection of *HttpPostedFile*s and upload those? http://msdn.microsoft.com/en-us/library/system.web.httppostedfile.aspx I don't think it is possible but would be glad to be proven wrong. Is there a different asp.net method or control that will easily allow uploading multiple files from client to server?

• Should I go vor Arrays or Objects in PHP in a CouchDB/Ajax app?

  - by karlthorwald

  I find myself converting between array and object all the time in PHP application that uses couchDB and Ajax. Of course I am also converting objects to JSON and back (for sometimes couchdb but mostly Ajax), but this is not so much disturbing my workflow. At the present I have php objects that are returned by the CouchDB modules I use and on the other hand I have the old habbit to return arrays like array("error"="not found","data"=$dataObj) from my functions. This leads to a mixed occurence of real php objects and nested arrays and I cast with (object) or (array) if necessary. The worst thing is that I know more or less by heart what a function returns, but not what type (array or object), so I often run into type errors. My plan is now to always cast arrays to objects before returning from a function. Of course this implies a lot of refactoring. Is this the right way to go? What about the conversion overhead? Other ideas or tips? Edit: Kenaniah's answer suggests I should go the other way, this would mean I'd cast everything to arrays. And for all the Ajax / JSON stuff and also for CouchDB I would use $myarray = json_decode($json_data,$assoc = false) Even more work to change all the CouchDB and Ajax functions but in the end I have better code.

• Reading from the Registry in ASP.NET

  - by Filip Ekberg

  I have a Library ( DLL ) that has a method with the following: var masterKey = Registry. LocalMachine. OpenSubKey("SOFTWARE\\Microsoft\\Dynamics\\5.0\\"); When running this method in an WinForms applicaiton, masterKey is not null and when running this in asp.net masterKey is null! I've checked the executing user with WindowsIdentity.GetCurrent().Name and the same user is executing both applications. The asp.net application is executed in visual studio ( debug: F5 ) and so is the WinForms application. How come I cannot read the key in asp.net?

• Silverlight vs ASP.NET for Business?

  - by Sahat

  Which of these two technologies has bigger demand today? I have plenty of free time this summer so I was thinking of learning either ASP.NET or Silverlight 4, and get an internship this coming Fall. If you've read my other question here on SO "Financial Market Developer Dilemma" then you already know that I am planning to work in the financial industry a few years from now. So my questions are: Which technology would benefit me more in the long term: Silverlight or ASP.NET? Which one pays more $$$? Which one has higher demand? What is the learning curve like for ASP.NET and Silverlight? Thanks in advance!

• ASP:LinkButton and Eval

  - by sgibbons

  I'm using an ASP:LinkButton inside of an ItemTemplate inside of a TemplateField in a GridView. For the command argument for the link button I want to pass the ID of the row from the datasource that the gridview is bound to, so I'm doing something like this: <asp:LinkButton ID="viewLogButton" CommandName="viewLog" CommandArgument="<%#Eval("ID")%>" Text="View Log" runat="server"/> Unfortunately, the resulting HTML is this: <asp:LinkButton ID="viewLogButton" CommandName="viewLog" CommandArgument="3" Text="View Log" runat="server"/> It seems that it is parsing the Eval() properly, but this is somehow causing it not to parse the LinkButton tag and just dump it out as literal text. Does anyone know: a) why this is happening and, b) what a good solution to this problem is?

• ASP.NET Canceling the Default Submit Button

  - by Ryan Smith

  I have an ASP.NET application where there's a few ASP.NET buttons and several plain HTML buttons. Anytime there's a textbox where a user hits enter, the ASP.NET button trys to submit the form. I know I can change the defaultButton, but I don't want there to be any default button. I just want it so when the user presses enter it doesn't do anything. I've tried setting defaultButton to blank, but that doesn't seem to work and I can't seem to find the answer anywhere on the web. What's the code to make this happen? Thanks.

• Open source ASP.net webforms examples

  - by Yaaqov

  I learning ASP.net, and am looking to create a rather straightforward WebForms ASP.net application, but I have very limited examples to work with. Is there a site that has a lot of ASP.net WebForms projects that are downloadable? Books seem to focus on narrow aspects of using Webforms, like session control, or using master pages, but I'm looking for examples of how a whole app comes together. Or, better yet, is there someone willing to help a new developer out one-on-one by sharing a project or two of his? I'd appreciate any help. Thanks.

• What could cause "Connection Interrupted" on LocalHost when debugging in ASP.NET

  - by Jeff Dalley

  I'm trying to run a freshly created ASP.NET Website using C#, however when I do so it launches FireFox and attempts to connect to http://localhost:1295/WebSite1/Default.aspx (for example), but after about 10-15 seconds it displays a "Connection Interrupted - The connection to the server was reset while the page was loading." Error. This issue is also present with older ASP.NET C# pages/Web Services I've built in the past, nothing is actually running off the ASP.NET Development server. I am using: Windows XP Pro SP2, Visual Studio 2008 For reference I have SQL Server 2005 Developer Edition installed as well. I have tried: Browsing it with IE instead of Mozilla Trying 2.0 framework instead of 3.5 Reinstalling Visual Studio 2008 This problem seems so trivial the more I think about it, but I havn't been able to work it out just yet! Appreciate any help on the matter.

• What VS Projecttype for Model and Database?

  - by Tim

  Hello folks, i've just started a new asp.net project which could increase fastly(a small erp-system for our company). So i thought it would be a good idea to split at least the model from the view/controller(the asp.net project). Because it could be that i need to access some classes and the database from a windows app in future, i dicided to put the Model into its own Project. What Visual Studio 2005 Professional Projecttype is most suitable for this requirement and why? SqlServerProject (DB is MS Sql Server 2005 EP) Class Library Web Service Application Database project no separate Project/other(keep in mind VS 2005 has no ASP.NET MVC-Project) Thanks
