• service not defined when precompiling a web app with AJAX-enabled WCF Service

  - by Omar Mefire

  I created a web application in which one .aspx page calls an AJAX-enabled WCF service (created with Visual Studio 2008 Add New Item - AJAX-enabled WCF Service). when I test the application in Visual Studio, it works and the page can call the service from Javascript but when I "publish" (code precompilation using Visual Studio) it to the local IIS Server, I get an error : "service ThunServ is undefined" in my .html page. I've been spending quite a time to solve this problem but to no avail. Attarea.

• How to Uninstall License key

  - by balexandre

  I have bought and updated my Win 7 Pro to Windows 8 Professional and it's great ... all in all, I wanna keep using Windows 8, but something went wrong with Visual Studio 2012 Professional installation and there is no way I can install the target version for .NET 4.0 and I really need this to comply with old projects without affecting all the other developers. I do have an official license key bought when installing Windows 8, my question is, now that I need to format Install Win 7 Pro Upgrade to Win 8 Pro how do I make sure my next activation is successfully? In other words, how can I, not change, but remove my license so I can re-use it again when everything is fresh and updated

• Can I allow a write access to a particular registry key without elevation?

  - by 280Z28

  I develop an extension for Visual Studio 2005, 2008, and 2010. The Visual Studio 2005 SDK requires write access to the following registry key during builds. The normal way to handle this run Visual Studio with elevated privileges. The entire issue can be avoided if there's some way I can set permissions to allow access to this particular registry key without elevation: HKLM\SOFTWARE\Microsoft\VisualStudio\8.0Exp Side note: This key is only used for testing Visual Studio 2005 extensions. The issue does not occur on client machines so this is just a workaround for my own development machine.

• How to setup an iTunes library to use between two Macs?

  - by stead1984

  As you can tell this is no where near work related. I have an iMac G5 where my itunes is currently hosted, I have also just got a new MacBook Pro. What I want to be able to do is sync my itunes library from my iMac to my MacBook Pro, that way it can be accessible away from my home network, then if I make any changes to the itunes library (like change a track name) it will sync these changes back once I connect back to the home network. My current itunes contains music, videos, podcasts, playlists and iPhone apps, I would also like iTunes to track play counts collectively between the iMac and the MacBook Pro.

• When did Apple stop using the name "Macintosh" in favor of "Mac", and does anyone know why?

  - by schnapple

  As of a few months ago I finally joined the ranks of Macintosh owners. Except "Macintosh" doesn't seem to exist anymore for some reason. I noticed everything was "Mac", i.e. Mac OS X, MacBook, Mac mini, Mac Pro, etc. I didn't pay a whole lot of attention, but I always thought everyone was using shorthand. I mean "MacBook" is the real name of the computer, as is "iMac", but I always thought when people said "Mac Pro" they were just shortening the real name, "Macintosh Pro". And yet now when you go to the Apple site, a search for "Macintosh" turns up several instances of the name being used on various things (system requirements for old versions of QuickTime, the occasional piece of software with "for the Macintosh" in the name) but nothing from the main Mac pages. Near as I can tell they're really no longer called "Macintoshes" they're just "Macs" When did this happen, and does anyone know why Apple ditched the term "Macintosh"?

• Can I run ubuntu server 64 bit in a VirtualBox on a macbook host ?

  - by Doron

  Hello, I have a macbook pro with Intel Core 2 Due (It's actually not Pro, but it's a January 2009 unibody macbook - when there were both a unibody macbook, and a unibody macbook pro). I'm a php developer. I just installed a new hard drive, and in an effort to create a better development environment, I decided I'll try to create a virtual machine running ubuntu server. Since I need it to work fast (and since, well - it's just better, even if by a little) and I'll already have a delay due to the nature of the apache server being on a virtual host - I want to install a 64 bit version of ubuntu server. Can VirtualBox handle it? Is it s good idea to create such a development environment ? Thank you.

• Reimage several of the same model PC by copying the hard disk

  - by Tim Lehner

  I have several of the same machine (Dell Precision T3500) that originally came with Windows 7 Pro (there is a Windows 7 Pro OA product key sticker on top of each one). These were initially downgraded to XP by a former IT colleague, but are now back in the pool of unused machines. I am looking to format and install Windows 7 Pro on one of them using the latest official Win7 installer ISO with SP1 and then clone the hard drive to the other machines. The questions then, are: Does this even make sense, or is there a better way to do this considering I'm only doing it to 6 machines? Does this jive with MS licensing (we are the original purchaser of the machines, and thus, presumably, the license holder...but I'm no expert)? Is it possible to apply the individual 25-char product keys to the cloned machines after cloning? How far can I go in the config process (installing corporate standard apps and such) before I have to clone to the other machines considering the licensing/key questions?

• MacPro 1,1 video's card

  - by alexus

  I just bought a Mac Pro 1,1 from my coworkers and I'm looking to upgrade video card as the one inside is very noisy. What are my options? Basically I'm not looking to spend a lot of money, in fact i'd rather to spend as little as possible and get low end or mid range card, I'm not really playing games all that much so pretty much anything will do, I'd prefer 2xx series though. Current Mac Pro sells w/ GT120, Apple sells upgrade kit for $149 (which is okay, I just not sure if I'll be able to use this card on such an old Mac Pro)

• Selective coloring on dynamic TextBlock content in WPF

  - by user326579

  For selective coloring of static content the following suggestion works fine : http://stackoverflow.com/questions/2435880/is-it-possible-to-seletively-color-a-wrapping-textblock-in-silverlight-wpf However my content will be generated at runtime. For ex. if the Content generated is : "A Quick Brown Fox" Then I need they string "Brown" to be in color Brown and "Fox" to be in color Red The Keyword-Color list is fixed and available to me at runtime. I have looked at the Advanced TextFormatting page on MSDN, but it is too complicated for me, also the sample in there does not compile :( I am looking at creating a custom control which can do this for me. Let me know if anyone has any idea regarding how to go about this. Thanks in advance.

• Is there a "Language-Aware" diff?

  - by JS

  (Appologies for the poor title. I'm open to suggestions for a better one. "Language-gnostic", perhaps?) Does there exist a diff utility (preferably *nix-based) that will diff files based on how a (selectable) language compiler would view the code? For example, to a Python compiler, these two 'graphs are identical: # The quick brown fox jumped vs: # The quick brown # fox jumped Telling most diffs (at least the one's I'm familiar with) to ignore spaces and linebreaks still causes them to flag a difference due to the extra '#'. "Language-sensitivity" would sure help to cut down on the "noise". Ideally, it would work in xemacs....(<-- probably pushing my luck? :-)

• objects don't snap in browser window

  - by gavin

  I've recently upgraded from XP Pro to Windows7 Pro - In XP Pro (and previous OS versions) you could move Thumbnails around in a window and they would snap/shuffle up/re-order themselves and be viewable as a slide show - it was unbelievably useful - I used it EVERY day, Windows 7 doesn't do this? Is there some setting I can change or is it just not there anymore? I use it for organising photo libraries for archiving - I haven't found any other way of doing this that suits my work. Does anyone know a way to get this feature back? Thanks

• How do I link a VS2008 C++ project as a DLL instead of a LIB?

  - by Clark Battle

  I have the C++ source code in a Visual Studio project from another developer that compiles into a static lib. I need to change it so that it builds a dll from that code so that I can call it from C#. I went into the project properties in Visual Studio and changed the configuration type to a DLL. However, it now gives lots of linker errors like: error LNK2001: unresolved external symbol __CAP_Enter_Function XXXFilter.obj XXXFramework What else do I need to do in Visual Studio and in the code to produce a dll from the code instead of a lib? The library is huge so writing a wrapper is not an option. I have the code so I should be able to make it build a dll. I am not a very experienced C++ dev but I am in C# and visual studio. Thanks

• What is windows 8 core?

  - by Journeyman Geek

  I've found some references, when looking for information on WAIK installs of windows 8 of a varient called windows 8 core, that can be installed off the professional edition disk. There's also a mention of it on winsupersite that says The cheapest, called MSDN Operating Systems, costs $699 a year ($499 renewal), and of course includes Windows 8 (Core), Windows 8 Pro, and Windows 8 Enterprise. You get five licenses each for Windows 8 Core and Pro, and one Multiple Activation Key (MAK) for Windows 8 Enterprise. What is windows 8 core? Is it the new 'home' edition or something else? What differentiates it from the pro and enterprise editions?

• Show surrounding words when searching for a specific word in a text file (Ruby)

  - by Ezra

  Hi, I'm very new to ruby. I'm trying to search for any instance of a word in a text file (not the problem). Then when the word is discovered, it would show the surrounding text (maybe 3-4 words before and after the target word, instead of the whole line), output to a list of instances and continue searching. Example "The quick brown fox jumped over the lazy dog." Search word = "jumped" Output = "...brown fox jumped over the..." Any help is appreciated. Thanks!

• A rectangle drawn with DrawingContext.DrawRectangle blocks mouse

  - by dharmatech

  The WPF program below puts up a window which looks like this: Mouse-movement outside the black square causes the window title to be updated with the mouse's position. The updating stops when the mouse enters the square. I'd like for MouseMove to continue to trigger even when the mouse is over the square. Is there a way to do this? using System.Windows; using System.Windows.Controls; using System.Windows.Media; namespace Wpf_Particle_Demo { class DrawingVisualElement : FrameworkElement { public DrawingVisual visual; public DrawingVisualElement() { visual = new DrawingVisual(); } protected override int VisualChildrenCount { get { return 1; } } protected override Visual GetVisualChild(int index) { return visual; } } public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var canvas = new Canvas(); Content = canvas; var element = new DrawingVisualElement(); canvas.Children.Add(element); CompositionTarget.Rendering += (s, e) => { using (var dc = element.visual.RenderOpen()) dc.DrawRectangle(Brushes.Black, null, new Rect(0, 0, 50, 50)); }; MouseMove += (s, e) => Title = e.GetPosition(canvas).ToString(); } } }

• .net 3.5 to 4.0 Migration

  - by SARAVAN

  Currently we are doing a payroll application in Microsoft Visual Studio 2008 (.Net 3.5) using some of the latest features like WCF, WF and the development for the same has almost completed. However, clients have shown their interest in migrating the developed payroll application in Microsoft Visual Studio 2008 (.Net 3.5) to Microsoft Visual Studio 2010 (.Net 4.0). I don't have an idea about the expected challenges in the migration or if its just going to be very smooth. Any thoughts or comments?

• Basic string and value functions in Objective-C for iPhone

  - by David Maitland

  I have very little programming knowledge; only a fair bit in Visual Basic. How do I take a value from a text field, then do some simple math such as divide the value by two, then display it back to the user in the same field? In Visual Basic you could just do txtBoxOne.text = txtBoxOne.text / 2 I understand this question is more than one question and is very basic stuff, but I need to get my head out of Visual Basic and into where I should be :)

• Solution: Testing Web Services with MSTest on Team Build

  - by Martin Hinshelwood

  Guess what. About 20 minutes after I fixed the build, Allan broke it again! Update: 4th March 2010 – After having huge problems getting this working I read Billy Wang’s post which showed me the light. The problem here is that even though the test passes locally it will not during an Automated Build. When you send your tests to the build server it does not understand that you want to spin up the web site and run tests against that! When you run the test in Visual Studio it spins up the web site anyway, but would you expect your test to pass if you told the website not to spin up? Of course not. So, when you send the code to the build server you need to tell it what to spin up. First, the best way to get the parameters you need is to right click on the method you want to test and select “Create Unit Test”. This will detect wither you are running in IIS or ASP.NET Development Server or None, and create the relevant tags. Figure: Right clicking on “SaveDefaultProjectFile” will produce a context menu with “Create Unit tests…” on it. If you use this option it will AutoDetect most of the Attributes that are required. /// <summary> ///A test for SSW.SQLDeploy.SilverlightUI.Web.Services.IProfileService.SaveDefaultProjectFile ///</summary> // TODO: Ensure that the UrlToTest attribute specifies a URL to an ASP.NET page (for example, // http://.../Default.aspx). This is necessary for the unit test to be executed on the web server, // whether you are testing a page, web service, or a WCF service. [TestMethod()] [HostType("ASP.NET")] [AspNetDevelopmentServerHost("D:\\Workspaces\\SSW\\SSW\\SqlDeploy\\DEV\\Main\\SSW.SQLDeploy.SilverlightUI.Web", "/")] [UrlToTest("http://localhost:3100/")] [DeploymentItem("SSW.SQLDeploy.SilverlightUI.Web.dll")] public void SaveDefaultProjectFileTest() { IProfileService target = new ProfileService(); // TODO: Initialize to an appropriate value string strComputerName = string.Empty; // TODO: Initialize to an appropriate value bool expected = false; // TODO: Initialize to an appropriate value bool actual; actual = target.SaveDefaultProjectFile(strComputerName); Assert.AreEqual(expected, actual); Assert.Inconclusive("Verify the correctness of this test method."); } Figure: Auto created code that shows the attributes required to run correctly in IIS or in this case ASP.NET Development Server If you are a purist and don’t like creating unit tests like this then you just need to add the three attributes manually. HostType – This attribute specified what host to use. Its an extensibility point, so you could write your own. Or you could just use “ASP.NET”. UrlToTest – This specifies the start URL. For most tests it does not matter which page you call, as long as it is a valid page otherwise your test may not run on the server, but may pass anyway. AspNetDevelopmentServerHost – This is a nasty one, it is only used if you are using ASP.NET Development Host and is unnecessary if you are using IIS. This sets the host settings and the first value MUST be the physical path to the root of your web application. OK, so all that was rubbish and I could not get anything working using the MSDN documentation. Google provided very little help until I ran into Billy Wang’s post  and I heard that heavenly music that all developers hear when understanding dawns that what they have been doing up until now is just plain stupid. I am sure that the above will work when I am doing Web Unit Tests, but there is a much easier way when doing web services. You need to add the AspNetDevelopmentServer attribute to your code. This will tell MSTest to spin up an ASP.NET Development server to host the service. Specify the path to the web application you want to use. [AspNetDevelopmentServer("WebApp1", "D:\\Workspaces\\SSW\\SSW\\SqlDeploy\\DEV\\Main\\SSW.SQLDeploy.SilverlightUI.Web")] [DeploymentItem("SSW.SQLDeploy.SilverlightUI.Web.dll")] [TestMethod] public void ProfileService_Integration_SaveDefaultProjectFile_Returns_True() { ProfileServiceClient target = new ProfileServiceClient(); bool isTrue = target.SaveDefaultProjectFile("Mav"); Assert.AreEqual(true, isTrue); } Figure: This AspNetDevelopmentServer will make sure that the specified web application is launched. Now we can run the test and have it pass, but if the dynamically assigned ASP.NET Development server port changes what happens to the details in your app.config that was generated when creating a reference to the web service? Well, it would be wrong and the test would fail. This is where Billy’s helper method comes in. Once you have created an instance of your service call, and it has loaded the config, but before you make any calls to it you need to go in and dynamically set the Endpoint address to the same address as your dynamically hosted Web Application. using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.VisualStudio.TestTools.UnitTesting; using System.Reflection; using System.ServiceModel.Description; using System.ServiceModel; namespace SSW.SQLDeploy.Test { class WcfWebServiceHelper { public static bool TryUrlRedirection(object client, TestContext context, string identifier) { bool result = true; try { PropertyInfo property = client.GetType().GetProperty("Endpoint"); string webServer = context.Properties[string.Format("AspNetDevelopmentServer.{0}", identifier)].ToString(); Uri webServerUri = new Uri(webServer); ServiceEndpoint endpoint = (ServiceEndpoint)property.GetValue(client, null); EndpointAddressBuilder builder = new EndpointAddressBuilder(endpoint.Address); builder.Uri = new Uri(endpoint.Address.Uri.OriginalString.Replace(endpoint.Address.Uri.Authority, webServerUri.Authority)); endpoint.Address = builder.ToEndpointAddress(); } catch (Exception e) { context.WriteLine(e.Message); result = false; } return result; } } } Figure: This fixes a problem with the URL in your web.config not being the same as the dynamically hosted ASP.NET Development server port. We can now add a call to this method after we created the Proxy object and change the Endpoint for the Service to the correct one. This process is wrapped in an assert as if it fails there is no point in continuing. [AspNetDevelopmentServer("WebApp1", D:\\Workspaces\\SSW\\SSW\\SqlDeploy\\DEV\\Main\\SSW.SQLDeploy.SilverlightUI.Web")] [DeploymentItem("SSW.SQLDeploy.SilverlightUI.Web.dll")] [TestMethod] public void ProfileService_Integration_SaveDefaultProjectFile_Returns_True() { ProfileServiceClient target = new ProfileServiceClient(); Assert.IsTrue(WcfWebServiceHelper.TryUrlRedirection(target, TestContext, "WebApp1")); bool isTrue = target.SaveDefaultProjectFile("Mav"); Assert.AreEqual(true, isTrue); } Figure: Editing the Endpoint from the app.config on the fly to match the dynamically hosted ASP.NET Development Server URL and port is now easy. As you can imagine AspNetDevelopmentServer poses some problems of you have multiple developers. What are the chances of everyone using the same location to store the source? What about if you are using a build server, how do you tell MSTest where to look for the files? To the rescue is a property called" “%PathToWebRoot%” which is always right on the build server. It will always point to your build drop folder for your solutions web sites. Which will be “\\tfs.ssw.com.au\BuildDrop\[BuildName]\Debug\_PrecompiledWeb\” or whatever your build drop location is. So lets change the code above to add this. [AspNetDevelopmentServer("WebApp1", "%PathToWebRoot%\\SSW.SQLDeploy.SilverlightUI.Web")] [DeploymentItem("SSW.SQLDeploy.SilverlightUI.Web.dll")] [TestMethod] public void ProfileService_Integration_SaveDefaultProjectFile_Returns_True() { ProfileServiceClient target = new ProfileServiceClient(); Assert.IsTrue(WcfWebServiceHelper.TryUrlRedirection(target, TestContext, "WebApp1")); bool isTrue = target.SaveDefaultProjectFile("Mav"); Assert.AreEqual(true, isTrue); } Figure: Adding %PathToWebRoot% to the AspNetDevelopmentServer path makes it work everywhere. Now we have another problem… this will ONLY run on the build server and will fail locally as %PathToWebRoot%’s default value is “C:\Users\[profile]\Documents\Visual Studio 2010\Projects”. Well this sucks… How do we get the test to run on any build server and any developer laptop. Open “Tools | Options | Test Tools | Test Execution” in Visual Studio and you will see a field called “Web application root directory”. This is where you override that default above. Figure: You can override the default website location for tests. In my case I would put in “D:\Workspaces\SSW\SSW\SqlDeploy\DEV\Main” and all the developers working with this branch would put in the folder that they have mapped. Can you see a problem? What is I create a “$/SSW/SqlDeploy/DEV/34567” branch from Main and I want to run tests in there. Well… I would have to change the value above. This is not ideal, but as you can put your projects anywhere on a computer, it has to be done. Conclusion Although this looks convoluted and complicated there are real problems being solved here that mean that you have a test ANYWHERE solution. Any build server, any Developer workstation.

• July 2013 Release of the Ajax Control Toolkit

  - by Stephen.Walther

  I’m super excited to announce the July 2013 release of the Ajax Control Toolkit. You can download the new version of the Ajax Control Toolkit from CodePlex (http://ajaxControlToolkit.CodePlex.com) or install the Ajax Control Toolkit from NuGet: With this release, we have completely rewritten the way the Ajax Control Toolkit combines, minifies, gzips, and caches JavaScript files. The goal of this release was to improve the performance of the Ajax Control Toolkit and make it easier to create custom Ajax Control Toolkit controls. Improving Ajax Control Toolkit Performance Previous releases of the Ajax Control Toolkit optimized performance for a single page but not multiple pages. When you visited each page in an app, the Ajax Control Toolkit would combine all of the JavaScript files required by the controls in the page into a new JavaScript file. So, even if every page in your app used the exact same controls, visitors would need to download a new combined Ajax Control Toolkit JavaScript file for each page visited. Downloading new scripts for each page that you visit does not lead to good performance. In general, you want to make as few requests for JavaScript files as possible and take maximum advantage of caching. For most apps, you would get much better performance if you could specify all of the Ajax Control Toolkit controls that you need for your entire app and create a single JavaScript file which could be used across your entire app. What a great idea! Introducing Control Bundles With this release of the Ajax Control Toolkit, we introduce the concept of Control Bundles. You define a Control Bundle to indicate the set of Ajax Control Toolkit controls that you want to use in your app. You define Control Bundles in a file located in the root of your application named AjaxControlToolkit.config. For example, the following AjaxControlToolkit.config file defines two Control Bundles: <ajaxControlToolkit> <controlBundles> <controlBundle> <control name="CalendarExtender" /> <control name="ComboBox" /> </controlBundle> <controlBundle name="CalendarBundle"> <control name="CalendarExtender"></control> </controlBundle> </controlBundles> </ajaxControlToolkit> The first Control Bundle in the file above does not have a name. When a Control Bundle does not have a name then it becomes the default Control Bundle for your entire application. The default Control Bundle is used by the ToolkitScriptManager by default. For example, the default Control Bundle is used when you declare the ToolkitScriptManager like this:  <ajaxToolkit:ToolkitScriptManager runat=”server” /> The default Control Bundle defined in the file above includes all of the scripts required for the CalendarExtender and ComboBox controls. All of the scripts required for both of these controls are combined, minified, gzipped, and cached automatically. The AjaxControlToolkit.config file above also defines a second Control Bundle with the name CalendarBundle. Here’s how you would use the CalendarBundle with the ToolkitScriptManager: <ajaxToolkit:ToolkitScriptManager runat="server"> <ControlBundles> <ajaxToolkit:ControlBundle Name="CalendarBundle" /> </ControlBundles> </ajaxToolkit:ToolkitScriptManager> In this case, only the JavaScript files required by the CalendarExtender control, and not the ComboBox, would be downloaded because the CalendarBundle lists only the CalendarExtender control. You can use multiple named control bundles with the ToolkitScriptManager and you will get all of the scripts from both bundles. Support for ControlBundles is a new feature of the ToolkitScriptManager that we introduced with this release. We extended the ToolkitScriptManager to support the Control Bundles that you can define in the AjaxControlToolkit.config file. Let me be explicit about the rules for Control Bundles: 1. If you do not create an AjaxControlToolkit.config file then the ToolkitScriptManager will download all of the JavaScript files required for all of the controls in the Ajax Control Toolkit. This is the easy but low performance option. 2. If you create an AjaxControlToolkit.config file and create a ControlBundle without a name then the ToolkitScriptManager uses that Control Bundle by default. For example, if you plan to use only the CalendarExtender and ComboBox controls in your application then you should create a default bundle that lists only these two controls. 3. If you create an AjaxControlToolkit.config file and create one or more named Control Bundles then you can use these named Control Bundles with the ToolkitScriptManager. For example, you might want to use different subsets of the Ajax Control Toolkit controls in different sections of your app. I should also mention that you can use the AjaxControlToolkit.config file with custom Ajax Control Toolkit controls – new controls that you write. For example, here is how you would register a set of custom controls from an assembly named MyAssembly: <ajaxControlToolkit> <controlBundles> <controlBundle name="CustomBundle"> <control name="MyAssembly.MyControl1" assembly="MyAssembly" /> <control name="MyAssembly.MyControl2" assembly="MyAssembly" /> </controlBundle> </ajaxControlToolkit> What about ASP.NET Bundling and Minification? The idea of Control Bundles is similar to the idea of Script Bundles used in ASP.NET Bundling and Minification. You might be wondering why we didn’t simply use Script Bundles with the Ajax Control Toolkit. There were several reasons. First, ASP.NET Bundling does not work with scripts embedded in an assembly. Because all of the scripts used by the Ajax Control Toolkit are embedded in the AjaxControlToolkit.dll assembly, ASP.NET Bundling was not an option. Second, Web Forms developers typically think at the level of controls and not at the level of individual scripts. We believe that it makes more sense for a Web Forms developer to specify the controls that they need in an app (CalendarExtender, ToggleButton) instead of the individual scripts that they need in an app (the 15 or so scripts required by the CalenderExtender). Finally, ASP.NET Bundling does not work with older versions of ASP.NET. The Ajax Control Toolkit needs to support ASP.NET 3.5, ASP.NET 4.0, and ASP.NET 4.5. Therefore, using ASP.NET Bundling was not an option. There is nothing wrong with using Control Bundles and Script Bundles side-by-side. The ASP.NET 4.0 and 4.5 ToolkitScriptManager supports both approaches to bundling scripts. Using the AjaxControlToolkit.CombineScriptsHandler Browsers cache JavaScript files by URL. For example, if you request the exact same JavaScript file from two different URLs then the exact same JavaScript file must be downloaded twice. However, if you request the same JavaScript file from the same URL more than once then it only needs to be downloaded once. With this release of the Ajax Control Toolkit, we have introduced a new HTTP Handler named the AjaxControlToolkit.CombineScriptsHandler. If you register this handler in your web.config file then the Ajax Control Toolkit can cache your JavaScript files for up to one year in the future automatically. You should register the handler in two places in your web.config file: in the <httpHandlers> section and the <system.webServer> section (don’t forget to register the handler for the AjaxFileUpload while you are there!). <httpHandlers> <add verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit" /> <add verb="*" path="CombineScriptsHandler.axd" type="AjaxControlToolkit.CombineScriptsHandler, AjaxControlToolkit" /> </httpHandlers> <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <handlers> <add name="AjaxFileUploadHandler" verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit" /> <add name="CombineScriptsHandler" verb="*" path="CombineScriptsHandler.axd" type="AjaxControlToolkit.CombineScriptsHandler, AjaxControlToolkit" /> </handlers> <system.webServer> The handler is only used in release mode and not in debug mode. You can enable release mode in your web.config file like this: <compilation debug=”false”> You also can override the web.config setting with the ToolkitScriptManager like this: <act:ToolkitScriptManager ScriptMode=”Release” runat=”server”/> In release mode, scripts are combined, minified, gzipped, and cached with a far future cache header automatically. When the handler is not registered, scripts are requested from the page that contains the ToolkitScriptManager: When the handler is registered in the web.config file, scripts are requested from the handler: If you want the best performance, always register the handler. That way, the Ajax Control Toolkit can cache the bundled scripts across page requests with a far future cache header. If you don’t register the handler then a new JavaScript file must be downloaded whenever you travel to a new page. Dynamic Bundling and Minification Previous releases of the Ajax Control Toolkit used a Visual Studio build task to minify the JavaScript files used by the Ajax Control Toolkit controls. The disadvantage of this approach to minification is that it made it difficult to create custom Ajax Control Toolkit controls. Starting with this release of the Ajax Control Toolkit, we support dynamic minification. The JavaScript files in the Ajax Control Toolkit are minified at runtime instead of at build time. Scripts are minified only when in release mode. You can specify release mode with the web.config file or with the ToolkitScriptManager ScriptMode property. Because of this change, the Ajax Control Toolkit now depends on the Ajax Minifier. You must include a reference to AjaxMin.dll in your Visual Studio project or you cannot take advantage of runtime minification. If you install the Ajax Control Toolkit from NuGet then AjaxMin.dll is added to your project as a NuGet dependency automatically. If you download the Ajax Control Toolkit from CodePlex then the AjaxMin.dll is included in the download. This change means that you no longer need to do anything special to create a custom Ajax Control Toolkit. As an open source project, we hope more people will contribute to the Ajax Control Toolkit (Yes, I am looking at you.) We have been working hard on making it much easier to create new custom controls. More on this subject with the next release of the Ajax Control Toolkit. A Single Visual Studio Solution We also made substantial changes to the Visual Studio solution and projects used by the Ajax Control Toolkit with this release. This change will matter to you only if you need to work directly with the Ajax Control Toolkit source code. In previous releases of the Ajax Control Toolkit, we maintained separate solution and project files for ASP.NET 3.5, ASP.NET 4.0, and ASP.NET 4.5. Starting with this release, we now support a single Visual Studio 2012 solution that takes advantage of multi-targeting to build ASP.NET 3.5, ASP.NET 4.0, and ASP.NET 4.5 versions of the toolkit. This change means that you need Visual Studio 2012 to open the Ajax Control Toolkit project downloaded from CodePlex. For details on how we setup multi-targeting, please see Budi Adiono’s blog post: http://www.budiadiono.com/2013/07/25/visual-studio-2012-multi-targeting-framework-project/ Summary You can take advantage of this release of the Ajax Control Toolkit to significantly improve the performance of your website. You need to do two things: 1) You need to create an AjaxControlToolkit.config file which lists the controls used in your app and 2) You need to register the AjaxControlToolkit.CombineScriptsHandler in the web.config file. We made substantial changes to the Ajax Control Toolkit with this release. We think these changes will result in much better performance for multipage apps and make the process of building custom controls much easier. As always, we look forward to hearing your feedback.
