• Resons why I'm using php rather then asp.net [closed]

  - by spirytus

  I have basic idea of how asp .Net works, but finds all framework hard to use if you are a newbie. I found compiling, web applications vs websites and all that stuff you should know to program in asp .net a bit tedious and so personally I go with php to create small, to medium applications for my clients. There are couple of reasons for it: php is easy scripting language, top to bottom and you done. You still can create objects, classes and if you have idea of MVC its fairly easy to create basic structure yourself so you can keep you presentation layer "relatively" clean. Although I find myself still mixing basic logic in my view's, I am trying to stick to booleans, and for each loops. ASP .net keeps it cleaner as far as I know and I agree that this is great. Heaps of free stuff for php and lots of help everywhere Although choice of IDE's for php is very limited, I still don't have to be stuck with VisualStudio. Lets be honest.. you can program in whatever you like but does anyone uses anything else other than VS? For basic applications I create, Visual Studio doesn't come even close to notepad :) / phpEdit (or similar) combination. It lacks of many features I constantly use, although armies of developers are using it and it must be for good reason. Personally not a big fan of VS though. Being on the market for that long should make editing much easier. I know .Net comes with awesome set of controls, validators etc. which is truly awesome. For me the problem starts if I want my validator to behave slightly different way and lets say fade in/out error messages. I know its possible to extend it behavior, plug into lifecycle and output different JS to the client and so on. I just never see it happen in places I work, and honestly, I don't even think most of .net developers I worked with during last couple of years would know how to do that. In php I have to grab some plugin for jQuery and use it for validation, which is fairly easy task once you had done it before. Again I'm sure its easy for .net gurus, but for newbie like me its almost impossible. I found that many asp .net programmers are very limited in what they are able to do and basically whack together .net applications using same lame set of controls, not even bothering in looking into how it works and what if? Now I don't want to anger anyone :) I know there is huge number of excellent .Net developers who know their stuff and are able to extend controls and do all that magic in no time. I found it a bit annoying though that many of them stick to what is provided without even trying to make it better. Nothing against .net here, just a thought really :) I remember when asp.net came out the idea was that front-end people will not be able to screw anything up and do their fron-end stuff without worrying what happens behind. Now its never that easy and I always tend to get server side people to fix this and that during development. Things like ID's assigned to controls can very easily make your application break and if someone is pure HTML guy using VS its easy to break something. Thats my thoughs on php and .net and reasons why for my work I go with php. I know that once learned asp .net is awesome technology and summing all up php doesn't even come close to it. For someone like me however, individually developing small basic applications for clients, php seems to work much better. Please let me know your thoughts on the above :)

• Lucene.net create+lock errors in ASP.NET

  - by acidzombie24

  I have an issue with Lucene.net. It throws a lock exception. After poking around i notice these things. My code below works in an app bit when calling in Application_Start i get a NoSuchDirectoryException. Not closing the writer (as my code doesnt do below) i WILL get a LockObtainFailedException with the message Lock obtain timed out: SimpleFSLock@<FULL_PATH> from either app or asp.net These thread hinted when spawning threads they get less permissions then i do (but! my main thread has problems as well...) and one solution is to impersonate IIS. I am using visual studios 2010. I am not sure how full blown it is but my attempt to impersonate it failed. So my question is how do i have lucene create the directory and not throw an exception if dont close the writer for some reason (such as power going out)? http://stackoverflow.com/questions/2341163/why-is-my-lucene-index-getting-locked/2499285#2499285 http://stackoverflow.com/questions/1123517/lucene-net-and-i-o-threading-issue/1123981#1123981 static IndexWriter writer = null; static void lucene_init() { bool create = false; string dirname = "LuceneIndex_z"; if (System.IO.Directory.Exists(dirname) == false) create = true; var directory = FSDirectory.GetDirectory(dirname); var analyzer = new StandardAnalyzer(); writer = new IndexWriter(directory, analyzer, create); }

• How to configure Visual Studio 2010 code coverage for ASP.NET MVC unit tests

  - by DigiMortal

  I just got Visual Studio 2010 code coverage work with ASP.NET MVC application unit tests. Everything is simple after you have spent some time with forums, blogs and Google. To save your valuable time I wrote this posting to guide you through the process of making code coverage work with ASP.NET MVC application unit tests. After some fighting with Visual Studio I got everything to work as expected. I am still not very sure why users must deal with this mess, but okay – I survived it. Before you start configuring Visual Studio I expect your solution meets the following needs: there are at least one library that will be tested, there is at least on library that contains tests to be run, there are some classes and some tests for them, and, of course, you are using version of Visual Studio 2010 that supports tests (I have Visual Studio 2010 Ultimate). Now open the following screenshot to separate windows and follow the steps given below. Visual Studio 2010 Test Settings window. Click on image to see it at original size.  Double click on Local.testsettings under Solution Items. Test settings window will be opened. Select “Data and Diagnostics” from left pane. Mark checkboxes “ASP.NET Profiler” and “Code Coverage”. Move cursor to “Code Coverage” line and press Configure button or make double click on line. Assemblies selection window will be opened. Mark checkboxes that are located before assemblies about what you want code coverage reports and apply settings. Save your project and close Visual Studio. Run Visual Studio as Administrator and run tests. NB! Select Test => Run => Tests in Current Context from menu. When tests are run you can open code coverage results by selecting Test => Windows => Code Coverage Results from menu. Here you can see my example test results. Visual Studio 2010 Test Results window. All my tests passed this time. :) Click on image to see it at original size.  And here are the code coverage results. Visual Studio 2101 Code Coverage Results. I need a lot more tests for sure. Click on image to see it at original size.  As you can see everything was pretty simple. But it took me sometime to figure out how to get everything work as expected. Problems? You may face some problems when making code coverage work. Here is my short list of possible problems. Make sure you have all assemblies available for code coverage. In some cases it needs more libraries to be referenced as you currently have. By example, I had to add some more Enterprise Library assemblies to my project. You can use EventViewer to discover errors that where given during testing. Make sure you selected all testable assemblies from Code Coverage settings like shown above. Otherwise you may get empty results. Tests with code coverage are slower because we need ASP.NET profiler. If your machine slows down then try to free more resources.

• Move asp.net website to subfolder/subdomain

  - by brz dot net

  What is the effective way to deploy an asp.net website in subfolder/subdomain? Actually I need to keep web.config in root directory and modify following things for this. Web.config Location tags Web.config authentication forms tag Web.sitemap Style.css Response.redirect/Server.transfer Image path Is there any way to avoid these changes? So my development work is not more different from production. Means I am expecting one place where applied changes are effective on whole site. No need to modify path on each page.

• ASP.NET and WIF: Showing custom profile username as User.Identity.Name

  - by DigiMortal

  I am building ASP.NET MVC application that uses external services to authenticate users. For ASP.NET users are fully authenticated when they are redirected back from external service. In system they are logically authenticated when they have created user profiles. In this posting I will show you how to force ASP.NET MVC controller actions to demand existence of custom user profiles. Using external authentication sources with AppFabric Suppose you want to be user-friendly and you don’t force users to keep in mind another username/password when they visit your site. You can accept logins from different popular sites like Windows Live, Facebook, Yahoo, Google and many more. If user has account in some of these services then he or she can use his or her account to log in to your site. If you have community site then you usually have support for user profiles too. Some of these providers give you some information about users and other don’t. So only thing in common you get from all those providers is some unique ID that identifies user in service uniquely. Image above shows you how new user joins your site. Existing users who already have profile are directed to users homepage after they are authenticated. You can read more about how to solve semi-authorized users problem from my blog posting ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages. The other problem is related to usernames that we don’t get from all identity providers. Why is IIdentity.Name sometimes empty? The problem is described more specifically in my blog posting Identifying AppFabric Access Control Service users uniquely. Shortly the problem is that not all providers have claim called http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name. The following diagram illustrates what happens when user got token from AppFabric ACS and was redirected to your site. Now, when user was authenticated using Windows Live ID then we don’t have name claim in token and that’s why User.Identity.Name is empty. Okay, we can force nameidentifier to be used as name (we can do it in web.config file) but we have user profiles and we want username from profile to be shown when username is asked. Modifying name claim Now let’s force IClaimsIdentity to use username from our user profiles. You can read more about my profiles topic from my blog posting ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages and you can find some useful extension methods for claims identity from my blog posting Identifying AppFabric Access Control Service users uniquely. Here is what we do to set User.Identity.Name: we will check if user has profile, if user has profile we will check if User.Identity.Name matches the name given by profile, if names does not match then probably identity provider returned some name for user, we will remove name claim and recreate it with correct username, we will add new name claim to claims collection. All this stuff happens in Application_AuthorizeRequest event of our web application. The code is here. protected void Application_AuthorizeRequest() {     if (string.IsNullOrEmpty(User.Identity.Name))     {         var identity = User.Identity;         var profile = identity.GetProfile();         if (profile != null)         {             if (profile.UserName != identity.Name)             {                 identity.RemoveName();                   var claim = new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name", profile.UserName);                 var claimsIdentity = (IClaimsIdentity)identity;                 claimsIdentity.Claims.Add(claim);             }         }     } } RemoveName extension method is simple – it looks for name claims of IClaimsIdentity claims collection and removes them. public static void RemoveName(this IIdentity identity) {     if (identity == null)         return;       var claimsIndentity = identity as ClaimsIdentity;     if (claimsIndentity == null)         return;       for (var i = claimsIndentity.Claims.Count - 1; i >= 0; i--)     {         var claim = claimsIndentity.Claims[i];         if (claim.ClaimType == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name")             claimsIndentity.Claims.RemoveAt(i);     } } And we are done. Now User.Identity.Name returns the username from user profile and you can use it to show username of current user everywhere in your site. Conclusion Mixing AppFabric Access Control Service and Windows Identity Foundation with custom authorization logic is not impossible but a little bit tricky. This posting finishes my little series about AppFabric ACS and WIF for this time and hopefully you found some useful tricks, tips, hacks and code pieces you can use in your own applications.

• ASP.NET MVC 2 throws exception for ‘favicon.ico’

  - by nmarun

  I must be on fire or something – third blog in 2 days… awesome! Before I begin, in case you’re wondering, favicon.ico is the small image that appears to the left of your web address, once the page loads. In order to learn more about MVC or any thing for that matter, it’s better to look at the source itself. Since MVC is open source (at least some part of it is), I started looking at the source code that’s available for download. While doing so, I hit Steve Sanderson’s blog site where he explains in great detail the way to debug your app using ASP.NET MVC source code. For those who are not aware, Steve Sanderson’s book - Pro ASP.NET MVC Framework, is one of the best books to learn about MVC. Alrighty, I followed the article and I hit F5 to debug the default / unchanged MVC project. I put a breakpoint in the DefaultControllerFactory.cs, CreateController() method. To know a little more about this class and the method, read this. Sure enough, the control stopped at the breakpoint and I hit F5 again and the page rendered just fine. But then what’s this? The breakpoint was hit again, as if something else was being requested. I now hovered my mouse over the ‘controllerName’ parameter and it says – favicon.ico. This by itself was more than enough for me to raise my eye-brows, but what happened next just took the ground below my feet. Oh, oh, I’m sorry I’m just typing, no code, no image, so here are a couple of screen captures. The first one shows the request for the Home controller; I get ‘Home’ when I hover over the parameter: And here’s the one that shows the same for call for ‘favicon.ico’. So, I step through the code and when the control reaches line 91 – GetControllerInstance() method, I step in. This is when I had the ‘ground-losing’ experience. Wow, an exception is being thrown for this file and that too in RTM. For some reason MVC thinks, this as a controller and tries to run it through the MvcHandler and it hits this snag. So it seems like this will happen for any MVC 2 site and this did not happen for me in the previous version of MVC. Before I get to how to resolve it, here’s another way of reproducing this exception. Revert back all your changes that you did as mentioned in Steve’s blog above. Now, add a class to your MVC project and call it say, MyControllerFactory and let this inherit from DefaultControllerFactory class. (Read this for details on the DefaultControllerFactory class is and how it is used in a different context). Add an override for the CreateController() method and for the sake of this blog, just copy the same content from the DefaultControllerFactory class. The last step is to tell your MVC app to use the MyControllerFactory class instead of the default one. To do this, go to your Global.asax.cs file and add line 6 of the snippet below: 1: protected void Application_Start() 2: { 3: AreaRegistration.RegisterAllAreas(); 4:   5: RegisterRoutes(RouteTable.Routes); 6: ControllerBuilder.Current.SetControllerFactory(new MyControllerFactory()); 7: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Now, you’re ready to reproduce the issue. Just F5 the project and when you hit the overridden CreateController() method for the second time, this is what it looks like for me: And continuing further gives me the same exception. I believe this is something that MS should fix, as not having ‘favicon.ico’ file will be common for most of the applications. So I think the when you create an MVC project, line 6 should be added by default by Visual Studio itself: 1: public class MvcApplication : System.Web.HttpApplication 2: { 3: public static void RegisterRoutes(RouteCollection routes) 4: { 5: routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); 6: routes.IgnoreRoute("favicon.ico"); 7:   8: routes.MapRoute( 9: "Default", // Route name 10: "{controller}/{action}/{id}", // URL with parameters 11: new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults 12: ); 13: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } There it is, that’s the solution to avoid the exception altogether. I tried this both IE8 and Firefox browsers and was able to successfully reproduce the error. Hope someone will look at this issue and find a fix. Just before I finish up, I found another ‘bug’, if you want to call it, with Visual Studio 2008. Remember how you could change what browser you want your application to run in by just right clicking on the .aspx file and choosing ‘Browse with…’? Seems like that’s missing when you’re working with an MVC project. In order to test the above bug in the other browser, I had to load a classic ASP.NET project, change the settings and then run my MVC project. Felt kinda ‘icky’, for lack of a better word.

  In this post I am going to present a hands on example on how to use the Chart web server control. It is built into ASP.Net 4.0 and it is available from the Toolbox in VS 2010.It is a very rich feature control that supports many chart types, had support for 3-D chart types,supports smart data labels and client side ajax support. Let's move on with our example. 1) Launch VS 2010. I am using the Ultimate edition but the express edition will work fine. 2) Create an empty web site from the available templates...(read more)

• Building an ASP.Net 4.5 Web forms application - part 5

  - by nikolaosk

  ?his is the fifth post in a series of posts on how to design and implement an ASP.Net 4.5 Web Forms store that sells posters on line. There are 4 more posts in this series of posts.Please make sure you read them first.You can find the first post here. You can find the second post here. You can find the third post here.You can find the fourth here.  In this new post we will build on the previous posts and we will demonstrate how to display the details of a poster when the user clicks on an individual poster photo/link. We will add a FormView control on a web form and will bind data from the database. FormView is a great web server control for displaying the details of a single record. 1) Launch Visual Studio and open your solution where your project lives2) Add a new web form item on the project.Make sure you include the Master Page.Name it PosterDetails.aspx 3) Open the PosterDetails.aspx page. We will add some markup in this page. Have a look at the code below <asp:Content ID="Content2" ContentPlaceHolderID="FeaturedContent" runat="server">    <asp:FormView ID="posterDetails" runat="server" ItemType="PostersOnLine.DAL.Poster" SelectMethod ="GetPosterDetails">        <ItemTemplate>            <div>                <h1><%#:Item.PosterName %></h1>            </div>            <br />            <table>                <tr>                    <td>                        <img src="<%#:Item.PosterImgpath %>" border="1" alt="<%#:Item.PosterName %>" height="300" />                    </td>                    <td style="vertical-align: top">                        <b>Description:</b><br /><%#:Item.PosterDescription %>                        <br />                        <span><b>Price:</b>&nbsp;<%#: String.Format("{0:c}", Item.PosterPrice) %></span>                        <br />                        <span><b>Poster Number:</b>&nbsp;<%#:Item.PosterID %></span>                        <br />                    </td>                </tr>            </table>        </ItemTemplate>    </asp:FormView></asp:Content> I set the ItemType property to the Poster entity class and the SelectMethod to the GetPosterDetails method.The Item binding expression is available and we can retrieve properties of the Poster object.I retrieve the name, the image,the description and the price of each poster. 4) Now we need to write the GetPosterDetails method.In the code behind of the PosterDetails.aspx page we type public IQueryable<Poster> GetPosterDetails([QueryString("PosterID")]int? posterid)        {                    PosterContext ctx = new PosterContext();            IQueryable<Poster> query = ctx.Posters;            if (posterid.HasValue && posterid > 0)            {                query = query.Where(p => p.PosterID == posterid);            }            else            {                query = null;            }            return query;        } I bind the value from the query string to the posterid parameter at run time.This is all possible due to the QueryStringAttribute class that lives inside the System.Web.ModelBinding and gets the value of the query string variable PosterID.If there is a matching poster it is fetched from the database.If not,there is no data at all coming back from the database. 5) I run my application and then click on the "Midfielders" link.Then click on the first poster that appears from the left (Kenny Dalglish) and click on it to see the details. Have a look at the picture below to see the results.   You can see that now I have all the details of the poster in a new page.?ake sure you place breakpoints in the code so you can see what is really going on. Hope it helps!!!

• Building an ASP.Net 4.5 Web forms application - part 3

  - by nikolaosk

  ?his is the third post in a series of posts on how to design and implement an ASP.Net 4.5 Web Forms store that sells posters on line.Make sure you read the first and second post in the series.In this new post I will keep making some minor changes in the Markup,CSS and Master page but there is no point in presenting them here. They are just minor changes to reflect the content and layout I want my site to have. What I need to do now is to add some more pages and start displaying properly data from my database.Having said that I will show you how to add more pages to the web application and present data.1) Launch Visual Studio and open your solution where your project lives2) Add a new web form item on the project.Make sure you include the Master Page.Name it PosterList.aspxHave a look at the picture below 3) In Site.Master add the following link to the master page so the user can navigate to it.You should only add the line in bold     <nav>                    <ul id="menu">                        <li><a runat="server" href="~/">Home</a></li>                        <li><a runat="server" href="~/About.aspx">About</a></li>                        <li><a runat="server" href="~/Contact.aspx">Contact</a></li>                          <li><a href="http://weblogs.asp.net/PosterList.aspx">Posters</a></li>                    </ul>                </nav> 4) Now we need to display categories from the database. We will use a ListView web server control.Inside the <div id="body"> add the following code. <section id="postercat">       <asp:ListView ID="categoryList"                          ItemType="PostersOnLine.DAL.PosterCategory"                         runat="server"                        SelectMethod="GetPosterCategories" >                        <ItemTemplate>                                                    <a href="http://weblogs.asp.net/PosterList.aspx?id=<%#: Item.PosterCategoryID %>">                            <%#: Item.PosterCategoryName %>                            </a>                            </b>                        </ItemTemplate>                        <ItemSeparatorTemplate> ----- </ItemSeparatorTemplate>                    </asp:ListView>             </section>        Let me explain what the code does.We have the ListView control that displays each poster category's name.It also includes a link to the PosterList.aspx page with a query-string value containing the ID of the category. We set the ItemType property in the ListView to the PosterCategory entity .We set the SelectMethod property to a method GetPosterCategories. Now we can use the data-binding expression Item (<%#: %>) that is available within the ItemTemplate . 5) Now we must write the GetPosterCategories method. In the Site.Master.cs file add the following code.This is just a simple function that returns the poster categories.        public IQueryable<PosterCategory> GetPosterCategories()        {            PosterContext ctx = new PosterContext();            IQueryable<PosterCategory> query = ctx.PosterCategories;            return query;        } 6) I just changed a few things in the Site.css file to style the new <section> HTML element that includes the ListView control.#postercat {  text-align: center; background-color: #85C465;}     7) Build and run your application. Everything should compile now. Have a look at the picture below.The links (poster categories) appear.?he ListView control when is called during the page lifecycle calls the GetPosterCategories() method.The method is executed and returns the poster categories that are bound to the control.  When I click on any of the poster category links, the PosterList.aspx page will show up with the appropriate Id that is the PosterCategoryID.Have a look at the picture below  We will add more data-enabled controls in the next post in the PosterList.aspx page. Some people are complaining the posts are too long so I will keep them short. Hope it helps!!!

• ASP.NET 2.0 files work in one folder, but NOT in another

  - by Steve

  I am about to leap of a building. I have created an app for a client and all the files are in a folder on their D drive. Now it is time to go production, so I copied all my files and folders to their excisting classic asp folder on the same drive. BUT NOTHING WORKS. The only difference I can see is that DEV does not require HTTPS like the production site. I also made sure all the permissions are the same on both folder. I made sure that the GAC has read rights using the aspnet_regiis tool. I am at the end of my debug knowlegde, could someone please help me out. Here are the error messages I get from the application event log.

  If have the following web.config: <configuration> <system.web> <authentication mode="Forms"> <forms name="MembershipCookie" loginUrl="Login.aspx" protection="All" timeout="525600" slidingExpiration="true" enableCrossAppRedirects="true" path="/" /> </authentication> <authorization> <deny users="?" /> </authorization> </system.web> <location path="Default.aspx"> <system.web> <authorization> <allow users="*"/> </authorization> </system.web> </location> </configuration> The application is an ASP.NET 2.0 application running on Windows 2008R2/IIS7.5. If the site's application pool is configured to run ASP.NET 2.0 and I browse to http://example.com then Default.aspx is rendered as you'd expect from the rules above. However if the application pool is set to run ASP.NET 4.0 I am redirected to the login page. If I explicitly specify http://example.com/default.aspx then all is good and default.aspx renders. I've tried rewriting / -> /default.aspx (using IIS UrlRewriter 2.0) but the result is still the same, I get kicked to the login page. I've also tried this with an ASP.NET 4.0 application with the same result (which is where the problem initially arose). The reason I tried this with a 2.0 application was to see if there was a change in behaviour, and it seems that / is handled differently in 4.0. So to summarise, using the configuration above the following is observed: ASP.NET Version Url Behaviour ------------------------------------------------------------------------- 2.0 http://example.com Renders Default.aspx 2.0 http://example.com/Default.aspx Renders Default.aspx 4.0 http://example.com Redirects to Login.aspx 4.0 http://example.com/Default.aspx Renders Default.aspx Is this a bug/breaking change or have I missed something glaringly obvious?

• What to choose.... web service or WCF in asp.net 3.5

  - by HotTester

  The current project i am working on is extensively using web services and is made in .net 3.5. Now as we are going for implementation of second phase we are confused if we should either use WCF or web service as done previously ? Further is there anything new that can be useful and is coming up with .net 4.0 regarding web services or WCF. Thanks in advance. A good link for this is here.

• How to deploy ClickOnce .Net 3.5 application on 3.0 machine

  - by Buthrakaur

  I have .Net 3.5 SP1 WPF application which I'm successfully deploying to client computers using ClickOnce. Now I got new requirement - one of our clients need to run the application on machines equipped just with .Net 3.0 and it's entirely impossible to upgrade or install anything on the machines. I already tried to run the 3.5 application with some of the 3.5FW DLLs copied to the application directory and it worked without any problems. The only problem at the moment is ClickOnce. I already made it to include the 3.5FW System.*.dll files in list of application files, but it always aborts installation on 3.0 machine with this error message: Unable to install or run the application. The application requires that assembly System.Core Version 3.5.0.0 be installed in the Global Assembly Cache (GAC) first. Please contact your system administrator. I already tried to tweak prerequisites on Publish tab of my project, but no combination solved the issue. What part of ClickOnce is responsible for checking prerequisites? I already tried to deploy using mageui.exe, but the 3.5FW error is still present. What should I do to fore ClickOnce to stop checking any prerequisites at all? The project is created using VS2010.

• Adding an expression based image in a client report definition file (RDLC)

  - by rajbk

  In previous posts, I showed you how to create a report using Visual Studio 2010 and how to add a hyperlink to the report.  In this post, I show you how to add an expression based image to each row of the report. This similar to displaying a checkbox column for Boolean values.  A sample project is attached to the bottom of this post. To start off, download the project we created earlier from here.  The report we created had a “Discontinued” column of type Boolean. We are going to change it to display an “available” icon or “unavailable” icon based on the “Discontinued” row value.    Load the project and double click on Products.rdlc. With the report design surface active, you will see the “Report Data” tool window. Right click on the Images folder and select “Add Image..”   Add the available_icon.png and discontinued_icon.png images (the sample project at the end of this post has the icon png files)    You can see the images we added in the “Report Data” tool window.   Drag and drop the available_icon into the “Discontinued” column row (not the header) We get a dialog box which allows us to set the image properties. We will add an expression that specifies the image to display based the “Discontinued” value from the Product table. Click on the expression (fx) button.   Add the following expression : = IIf(Fields!Discontinued.Value = True, “discontinued_icon”, “available_icon”)   Save and exit all dialog boxes. In the report design surface, resize the column header and change the text from “Discontinued” to “In Production”.   (Optional) Right click on the image cell (not header) , go to “Image Properties..” and offset it by 5pt from the left. (Optional) Change the border color since it is not set by default for image columns. We are done adding our image column! Compile the application and run it. You will see that the “In Production” column has red ‘x’ icons for discontinued products.

• ASP.NET MVC and ViewState

  - by nickyt

  Now I've seen some questions like this, but it's not exactly what I want to ask, so for all those screaming duplicate, I apologize :). I've barely touched ASP.NET MVC but from what I understand there is no ViewState/ControlState... fine. So my question is what is the alternative to retaining a control's state? Do we go back to old school ASP where we might simulate what ASP.NET ViewState/ControlState does by creating hidden form inputs with the control's state, or with MVC, do we just assume AJAX always and retain all state client-side and make AJAX calls to update? This question has some answers, http://stackoverflow.com/questions/1285547/maintaining-viewstate-in-asp-net-mvc, but not exactly what I'm looking for in an answer. UPDATE: Thanks for all the answers so far. Just to clear up what I'm not looking for and what I'm looking for: Not looking for: Session solution Cookie solution Not looking to mimic WebForms in MVC What I am/was looking for: A method that only retains the state on postback if data is not rebound to a control. Think WebForms with the scenario of only binding a grid on the initial page load, i.e. only rebinding the data when necessary. As I mentioned, I'm not trying to mimic WebForms, just wondering what mechanisms MVC offers.

• Trying to build a Drupal-like CMS in ASP.NET MVC - Newbie Questions

  - by user252160

  I am new to ASP.NET MVC, and the ASP.NET technology in general, so, please, excuse the stupidity of my questions. I have a lot of experience with php development and CMS customization (Drupal and Wordpress mainly), and I wanted to know whether some techniques could be applied in asp.net mvc. I want to know what exactly could be modified without recompiling an already built application Can I edit the views without recompiling the app. Can I create custom themes ? Can I add plugins compiled as dlls and use them at runtime. Can I "mark" the assembly in such a way that the web application will check on the next request and will reference it, without me manually adding it to the project and recompiling. I've heard that this is possible. I will make sure to add more when something comes up. The reason I am asking is because I'd like to try and develop a Drupal-like CMS (custom types, views, etc) in asp.net mvc. The dynamism of php will be quite a challenge to replicate in a compiled technology, yet I am ready to try.

• Write binary data as a response in an ASP.NET MVC web control

  - by Lou Franco

  I am trying to get a control that I wrote for ASP.NET to work in an ASP.NET MVC environment. Normally, the control does the normal thing, and that works fine Sometimes it needs to respond by clearing the response, writing an image to the response stream and changing the content type. When you do this, you get an exception "OutputStream is not available when a custom TextWriter is used". If I were a page or controller, I see how I can create custom responses with binary data, but I can't see how to do this from inside a control's render functions. To simplify it -- imagine I want to make a web control that renders to: <img src="pageThatControlIsOn?controlImage"> And I know how to look at incoming requests and recognize query strings that should be routed to the control. Now the control is supposed to respond with a generated image (content-type: image/png -- and the encoded image). In ASP.NET, we: Response.Clear(); Response.OutputStream.Write(thePngData); // this throws in MVC // set the content type, etc Response.End(); How am I supposed to do that in an ASP.NET MVC control?

• DropDownList Value not changing with UpdatePanel and ModalPopupExtender

  - by Richard

  Greetings, I have an asp.net webpage with an modalpopupextender inside of an updatepanel. When I click Ok on the popup, I can get the textbox values from the popup just fine, but the DropDownLists have the old/default value, not the new value I have selected for them.

• ASP.NET OleDbConnection Problem

  - by Matt

  I'm working on an ASP.NET website where I am using an asp:repeater with paging done through a VB.NET code-behind file. I'm having trouble with the database connection though. As far as I can tell, the paging is working, but I can't get the data to be certain. The database is a Microsoft Access database. The function that should be accessing the database is: Dim pagedData As New PagedDataSource Sub Page_Load(ByVal obj As Object, ByVal e As EventArgs) doPaging() End Sub Function getTheData() As DataTable Dim DS As New DataSet() Dim strConnect As New OleDbConnection("Provider = Microsoft.Jet.OLEDB.4.0;Data Source=App_Data/ArtDatabase.mdb") Dim objOleDBAdapter As New OleDbDataAdapter("SELECT ArtID, FileLocation, Title, UserName, ArtDate FROM Art ORDER BY Art.ArtDate DESC", strConnect) objOleDBAdapter.Fill(DS, "Art") Return DS.Tables("Art").Copy End Function Sub doPaging() pagedData.DataSource = getTheData().DefaultView pagedData.AllowPaging = True pagedData.PageSize = 2 Try pagedData.CurrentPageIndex = Int32.Parse(Request.QueryString("Page")).ToString() Catch ex As Exception pagedData.CurrentPageIndex = 0 End Try btnPrev.Visible = (Not pagedData.IsFirstPage) btnNext.Visible = (Not pagedData.IsLastPage) pageNumber.Text = (pagedData.CurrentPageIndex + 1) & " of " & pagedData.PageCount ArtRepeater.DataSource = pagedData ArtRepeater.DataBind() End Sub The ASP.NET is: <asp:Repeater ID="ArtRepeater" runat="server"> <HeaderTemplate> <h2>Items in Selected Category:</h2> </HeaderTemplate> <ItemTemplate> <li> <asp:HyperLink runat="server" ID="HyperLink" NavigateUrl='<%# Eval("ArtID", "ArtPiece.aspx?ArtID={0}") %>'> <img src="<%# Eval("FileLocation") %>" alt="<%# DataBinder.Eval(Container.DataItem, "Title") %>t"/> <br /> <%# DataBinder.Eval(Container.DataItem, "Title") %> </asp:HyperLink> </li> </ItemTemplate> </asp:Repeater>

• Blog engines for ASP.Net (maybe MVC) web sites

  - by J. Pablo Fernández

  I've built a web site on ASP.NET MVC and one little section of it should be a blog. I'm looking for a blog to integrate. In the worst case scenario it'd be a WordPress with a custom skin and RSS integration to the rest of the site. The best would be to have an ASP.NET MVC add-on, but I can live with ASP.NET WebForms. Do you have any recomendations on the engine? I've been checking out BlogEngine.Net and I'd like to have some other ideas to compare. Anything in particular you can point to regarding this integration?

• How to store multiple scroll positions for scrolling div element depending on active View in MultiView (asp.net webform

  - by Spence

  confusing title but the best way I can put it. Basically I am currently using a single div with overflow:auto that contains different GridViews. The GridViews are swapped by using a MultiView with each indiviudal view containing a single GridView. I would like to be able to store the scroll position of each view so that I can set the div's scroll position depending on the view that will be switched to. Here is how my page is set up. <div id="scrollingDiv" style="height:100%; overflow:auto;"> <div id="gridWrap"> <asp:UpdatePanel ID="UpdatePanel1" runat="server" RenderMode="Inline"> <ContentTemplate> <asp:MultiView ID="MultiView1" runat="server"> <asp:View ID="view1" runat="server"> <asp:GridView ID="gridView1" runat="server"> </asp:GridView> </asp:View> <asp:View ID="view2" runat="server"> <asp:GridView ID="gridView2" runat="server"> </asp:GridView> </asp:View> </asp:Multiview> </ContentTemplate> </asp:UpdatePanel> </div> </div> So scrollingDiv will contain all the Views and will scroll for each one of the GridViews. To switch between views I have a drop down connected to an protected void DropDownList_SelectedIndexChanged(object sender, EventArgs e) { switch (DownList.SelectedItem.Value) { case "view1": MultiView1.SetActiveView(view1); break; case "view2": MultiView1.SetActiveView(view2); break; } } I have been looking around and can't quite find something specific to my case. I would like to be able to use just the one overflow div but would understand if I had to make a separate overflow div for each view. Any help would be great, Thanks.
