• .NET 4.5 is an in-place replacement for .NET 4.0

  - by Rick Strahl

  With the betas for .NET 4.5 and Visual Studio 11 and Windows 8 shipping many people will be installing .NET 4.5 and hacking away on it. There are a number of great enhancements that are fairly transparent, but it's important to understand what .NET 4.5 actually is in terms of the CLR running on your machine. When .NET 4.5 is installed it effectively replaces .NET 4.0 on the machine. .NET 4.0 gets overwritten by a new version of .NET 4.5 which - according to Microsoft - is supposed to be 100% backwards compatible. While 100% backwards compatible sounds great, we all know that 100% is a hard number to hit, and even the aforementioned blog post at the Microsoft site acknowledges this. But there's so much more than backwards compatibility that makes this awkward at best and confusing at worst. What does ‘Replacement’ mean? When you install .NET 4.5 your .NET 4.0 assemblies in the \Windows\.NET Framework\V4.0.30319 are overwritten with a new set of assemblies. You end up with overwritten assemblies as well as a bunch of new ones (like the new System.Net.Http assemblies for example). The following screen shot demonstrates system.dll on my test machine (left) running .NET 4.5 on the right and my production laptop running stock .NET 4.0 (right):   Clearly they are different files with a difference in file sizes (interesting that the 4.5 version is actually smaller). That’s not all. If you actually query the runtime version when .NET 4.5 is installed with with Environment.Version you still get: 4.0.30319 If you open the properties of System.dll assembly in .NET 4.5 you'll also see: Notice that the file version is also left at 4.0.xxx. There are differences in build numbers: .NET 4.0 shows 261 and the current .NET 4.5 beta build is 17379. I suppose you can use assume a build number greater than 17000 is .NET 4.5, but that's pretty hokey to say the least. There’s no easy or obvious way to tell whether you are running on 4.0 or 4.5 – to the application they appear to be the same runtime version. And that is what Microsoft intends here. .NET 4.5 is intended as an in-place upgrade. Compile to 4.5 run on 4.0 – not quite! You can compile an application for .NET 4.5 and run it on the 4.0 runtime – that is until you hit a new feature that doesn’t exist on 4.0. At which point the app bombs at runtime. Say you write some code that is mostly .NET 4.0, but only has a few of the new features of .NET 4.5 like aync/await buried deep in the bowels of the application where it only fires occasionally. .NET will happily start your application and run everything 4.0 fine, until it hits that 4.5 code – and then crash unceremoniously at runtime. Oh joy! You can .NET 4.0 applications on .NET 4.5 of course and that should work without much fanfare. Different than .NET 3.0/3.5 Note that this in-place replacement is very different from the side by side installs of .NET 2.0 and 3.0/3.5 which all ran on the 2.0 version of the CLR. The two 3.x versions were basically library enhancements on top of the core .NET 2.0 runtime. Both versions ran under the .NET 2.0 runtime which wasn’t changed (other than for security patches and bug fixes) for the whole 3.x cycle. The 4.5 update instead completely replaces the .NET 4.0 runtime and leaves the actual version number set at v4.0.30319. When you build a new project with Visual Studio 2011, you can still target .NET 4.0 or you can target .NET 4.5. But you are in effect referencing the same set of assemblies for both regardless which version you use. What's different is the compiler used to compile and link your code so compiling with .NET 4.0 gives you just the subset of the functionality that is available in .NET 4.0, but when you use the 4.5 compiler you get the full functionality of what’s actually available in the assemblies and extra libraries. It doesn’t look like you will be able to use Visual Studio 2010 to develop .NET 4.5 applications. Good news – Bad news Microsoft is trying hard to experiment with every possible permutation of releasing new versions of the .NET framework apparently. No two updates have been the same. Clearly updating to a full new version of .NET (ie. .NET 2.0, 4.0 and at some point 5.0 runtimes) has its own set of challenges, but doing an in-place update of the runtime and then not even providing a good way to tell which version is installed is pretty whacky even by Microsoft’s standards. Especially given that .NET 4.5 includes a fairly significant update with all the aysnc functionality baked into the runtime. Most of the IO APIs have been updated to support task based async operation which significantly affects many existing APIs. To make things worse .NET 4.5 will be the initial version of .NET that ships with Windows 8 so it will be with us for a long time to come unless Microsoft finally decides to push .NET versions onto Windows machines as part of system upgrades (which currently doesn’t happen). This is the same story we had when Vista launched with .NET 3.0 which was a minor version that quickly was replaced by 3.5 which was more long lived and practical. People had enough problems dealing with the confusing versioning of the 3.x versions which ran on .NET 2.0. I can’t count the amount support calls and questions I’ve fielded because people couldn’t find a .NET 3.5 entry in the IIS version dialog. The same is likely to happen with .NET 4.5. It’s all well and good when we know that .NET 4.5 is an in-place replacement, but administrators and IT folks not intimately familiar with .NET are unlikely to understand this nuance and end up thoroughly confused which version is installed. It’s hard for me to see any upside to an in-place update and I haven’t really seen a good explanation of why this approach was decided on. Sure if the version stays the same existing assembly bindings don’t break so applications can stay running through an update. I suppose this is useful for some component vendors and strongly signed assemblies in corporate environments. But seriously, if you are going to throw .NET 4.5 into the mix, who won’t be recompiling all code and thoroughly test that code to work on .NET 4.5? A recompile requirement doesn’t seem that serious in light of a major version upgrade.  Resources http://blogs.msdn.com/b/dotnet/archive/2011/09/26/compatibility-of-net-framework-4-5.aspx http://www.devproconnections.com/article/net-framework/net-framework-45-versioning-faces-problems-141160© Rick Strahl, West Wind Technologies, 2005-2012Posted in .NET   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Using the HTML5 &lt;input type=&quot;file&quot; multiple=&quot;multiple&quot;&gt; Tag in ASP.NET

  - by Rick Strahl

  Per HTML5 spec the <input type="file" /> tag allows for multiple files to be picked from a single File upload button. This is actually a very subtle change that's very useful as it makes it much easier to send multiple files to the server without using complex uploader controls. Please understand though, that even though you can send multiple files using the <input type="file" /> tag, the process of how those files are sent hasn't really changed - there's still no progress information or other hooks that allow you to automatically make for a nicer upload experience without additional libraries or code. For that you will still need some sort of library (I'll post an example in my next blog post using plUpload). All the new features allow for is to make it easier to select multiple images from disk in one operation. Where you might have required many file upload controls before to upload several files, one File control can potentially do the job. How it works To create a file input box that allows with multiple file support you can simply do:<form method="post" enctype="multipart/form-data"> <label>Upload Images:</label> <input type="file" multiple="multiple" name="File1" id="File1" accept="image/*" /> <hr /> <input type="submit" id="btnUpload" value="Upload Images" /> </form> Now when the file open dialog pops up - depending on the browser and whether the browser supports it - you can pick multiple files. Here I'm using Firefox using the thumbnail preview I can easily pick images to upload on a form: Note that I can select multiple images in the dialog all of which get stored in the file textbox. The UI for this can be different in some browsers. For example Chrome displays 3 files selected as text next to the Browse… button when I choose three rather than showing any files in the textbox. Most other browsers display the standard file input box and display the multiple filenames as a comma delimited list in the textbox. Note that you can also specify the accept attribute in the <input> tag, which specifies a mime-type to specify what type of content to allow.Here I'm only allowing images (image/*) and the browser complies by just showing me image files to display. Likewise I could use text/* for all text formats registered on the machine or text/xml to only show XML files (which would include xml,xst,xsd etc.). Capturing Files on the Server with ASP.NET When you upload files to an ASP.NET server there are a couple of things to be aware of. When multiple files are uploaded from a single file control, they are assigned the same name. In other words if I select 3 files to upload on the File1 control shown above I get three file form variables named File1. This means I can't easily retrieve files by their name:HttpPostedFileBase file = Request.Files["File1"]; because there will be multiple files for a given name. The above only selects the first file. Instead you can only reliably retrieve files by their index. Below is an example I use in app to capture a number of images uploaded and store them into a database using a business object and EF 4.2.for (int i = 0; i < Request.Files.Count; i++) { HttpPostedFileBase file = Request.Files[i]; if (file.ContentLength == 0) continue; if (file.ContentLength > App.Configuration.MaxImageUploadSize) { ErrorDisplay.ShowError("File " + file.FileName + " is too large. Max upload size is: " + App.Configuration.MaxImageUploadSize); return View("UploadClassic",model); } var image = new ClassifiedsBusiness.Image(); var ms = new MemoryStream(16498); file.InputStream.CopyTo(ms); image.Entered = DateTime.Now; image.EntryId = model.Entry.Id; image.ContentType = "image/jpeg"; image.ImageData = ms.ToArray(); ms.Seek(0, SeekOrigin.Begin); // resize image if necessary and turn into jpeg Bitmap bmp = Imaging.ResizeImage(ms.ToArray(), App.Configuration.MaxImageWidth, App.Configuration.MaxImageHeight); ms.Close(); ms = new MemoryStream(); bmp.Save(ms,ImageFormat.Jpeg); image.ImageData = ms.ToArray(); bmp.Dispose(); ms.Close(); model.Entry.Images.Add(image); } This works great and also allows you to capture input from multiple input controls if you are dealing with browsers that don't support multiple file selections in the file upload control. The important thing here is that I iterate over the files by index, rather than using a foreach loop over the Request.Files collection. The files collection returns key name strings, rather than the actual files (who thought that was good idea at Microsoft?), and so that isn't going to work since you end up getting multiple keys with the same name. Instead a plain for loop has to be used to loop over all files. Another Option in ASP.NET MVC If you're using ASP.NET MVC you can use the code above as well, but you have yet another option to capture multiple uploaded files by using a parameter for your post action method.public ActionResult Save(HttpPostedFileBase[] file1) { foreach (var file in file1) { if (file.ContentLength < 0) continue; // do something with the file }} Note that in order for this to work you have to specify each posted file variable individually in the parameter list. This works great if you have a single file upload to deal with. You can also pass this in addition to your main model to separate out a ViewModel and a set of uploaded files:public ActionResult Edit(EntryViewModel model,HttpPostedFileBase[] uploadedFile) You can also make the uploaded files part of the ViewModel itself - just make sure you use the appropriate naming for the variable name in the HTML document (since there's Html.FileFor() extension). Browser Support You knew this was coming, right? The feature is really nice, but unfortunately not supported universally yet. Once again Internet Explorer is the problem: No shipping version of Internet Explorer supports multiple file uploads. IE10 supposedly will, but even IE9 does not. All other major browsers - Chrome, Firefox, Safari and Opera - support multi-file uploads in their latest versions. So how can you handle this? If you need to provide multiple file uploads you can simply add multiple file selection boxes and let people either select multiple files with a single upload file box or use multiples. Alternately you can do some browser detection and if IE is used simply show the extra file upload boxes. It's not ideal, but either one of these approaches makes life easier for folks that use a decent browser and leaves you with a functional interface for those that don't. Here's a UI I recently built as an alternate uploader with multiple file upload buttons: I say this is my 'alternate' uploader - for my primary uploader I continue to use an add-in solution. Specifically I use plUpload and I'll discuss how that's implemented in my next post. Although I think that plUpload (and many of the other packaged JavaScript upload solutions) are a better choice especially for large uploads, for simple one file uploads input boxes work well enough. The advantage of this solution is that it's very easy to handle on the server side. Any of the JavaScript controls require special handling for uploads which I'll also discuss in my next post.© Rick Strahl, West Wind Technologies, 2005-2012Posted in HTML5  ASP.NET  MVC   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Fixing a SkyDrive Sync Disaster

  - by Rick Strahl

  For a few months I've been using SkyDrive to handle some basic synching tasks for a number of folders of mine. Specifically I've been dumping a few of my development folders into sky drive so I have a live running backup. It had been working just fine until about a week ago when something went awry. Badly! The idea is that the SkyDrive should sync files, but somewhere in its sync relationship it appears that SkyDrive got confused and assumed it needed to sync back older files to my local machine from the SkyDrive server. So rather than syncing my newer files to the server SkyDrive was pushing older files back to me. Because SkyDrive is so slow actually updating data it's not unusual for SkyDrive to be far behind in syncing and apparently some files were out of date by several months. Of course this is insidious because I didn't notice it for quite some time. I'd been happily working away on my files when a few days ago I noted a bunch of files with -RasXps (my machine name) popping up in various folders. At first I thought my Git repository was giving me a fit, but eventually realized that SkyDrive was actually pushing old files into my monitored folders. To be fair SkyDrive did make backups of the existing files, but by the time I caught it there were literally a few thousand files scattered on my machine that were now updated with old files from online. Here's what some of this looks like: If you look at the directory list you see a bunch of files with a -RasXps postfix appended to them. Those are the files that SkyDrive replaced and backed up on my machine. As you can see the backed up files are actually newer than the ones it pulled from the online SkyDrive. Unless I modified the files after they were updated they all were older than the existing local files. Not exactly how I imagined my synching would work. At first I started cleaning up this mess manually. In most cases the obvious solution was to simply delete the original file and replace with the -RasXps file, but not in all files. Some scrutiny was required and besides being a pain in the ass to rename files, quite frequently I had to dig out Beyond Compare to compare a few files where it wasn't quite clear what's wrong. I quickly realized that doing this by hand would be too hard for the large number of files that got hosed. Hacking together a small .NET Utility So, I figured the easiest way to tackle this is to write a small utility app that shows me all the mangled files that have backups, allows me to compare them and then quickly select and update them, removing the -RasXps file after choosing one of the two files. What I ended up with was a quick and dirty WinForms app that allows me to pick a root folder, and then shows all the -MachineName files: I start by picking a base folder and a template to search for - typically the -MachineName. Clicking Go brings up a list of all files in that folder and its subdirectories.  The list also displays the dates for the saved (-MachineName) file and the current file on disk, along with highlighting for the newer of the two. I can right click on any file and get a context menu pop up to open the folder in Explorer, or open Beyond Compare and view the two files to compare differences which I found very helpful for a number of files where I had modified the files after SkyDrive had updated to an old one. Typically these would be the green files (of which there were thankfully few). To 'fix' files I can select any number of files in the list, then use one of the three buttons on the right to apply an operation. I can use the Saved files - that is the backup file that SkyDrive created with the -MachineName extension (-RasXps above). Or I can use the current file, which is the file with the right name on disk right now and delete the -MachineName file. Or on some occasions I can just opt to delete both of them. For some files like binaries it's often easier to just delete and them be rebuild than choosing. For the most part the process involves accepting the pink files, and checking the few green files and see if any modifications were made since the file was updated incorrectly by SkyDrive. For me luckily those are few in number. Anyways, I thought I share this utility in case anybody else runs into this issue. I've included the VS2012 solution and all the source code so you can see how it works and you can tweak it as needed. The .NET 4.5 binaries are also included if you can't compile. Be warned though!  This rough code is provided as is and makes no guarantees or claims about file safety. All three of the action buttons on the form will delete data. It's a very rough utility and there are no safeguards that ask nicely before deleting files. I highly recommend you make a backup before you have at it. This tools is very narrow in focus, but it might also work with other sync issues from other vendors. I seem to remember that I had similar issues with SugarSync at some point and it too created the -MachineName style files on sync conflicts. Hope this helps somebody out so you can avoid wasting the better part of a full work day on this… Resources Download the Source Code and Binaries for SkyDrive Rescue© Rick Strahl, West Wind Technologies, 2005-2013Posted in Windows  .NET   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Dynamic Code for type casting Generic Types 'generically' in C#

  - by Rick Strahl

  C# is a strongly typed language and while that's a fundamental feature of the language there are more and more situations where dynamic types make a lot of sense. I've written quite a bit about how I use dynamic for creating new type extensions: Dynamic Types and DynamicObject References in C# Creating a dynamic, extensible C# Expando Object Creating a dynamic DataReader for dynamic Property Access Today I want to point out an example of a much simpler usage for dynamic that I use occasionally to get around potential static typing issues in C# code especially those concerning generic types. TypeCasting Generics Generic types have been around since .NET 2.0 I've run into a number of situations in the past - especially with generic types that don't implement specific interfaces that can be cast to - where I've been unable to properly cast an object when it's passed to a method or assigned to a property. Granted often this can be a sign of bad design, but in at least some situations the code that needs to be integrated is not under my control so I have to make due with what's available or the parent object is too complex or intermingled to be easily refactored to a new usage scenario. Here's an example that I ran into in my own RazorHosting library - so I have really no excuse, but I also don't see another clean way around it in this case. A Generic Example Imagine I've implemented a generic type like this: public class RazorEngine<TBaseTemplateType> where TBaseTemplateType : RazorTemplateBase, new() You can now happily instantiate new generic versions of this type with custom template bases or even a non-generic version which is implemented like this: public class RazorEngine : RazorEngine<RazorTemplateBase> { public RazorEngine() : base() { } } To instantiate one: var engine = new RazorEngine<MyCustomRazorTemplate>(); Now imagine that the template class receives a reference to the engine when it's instantiated. This code is fired as part of the Engine pipeline when it gets ready to execute the template. It instantiates the template and assigns itself to the template: var template = new TBaseTemplateType() { Engine = this } The problem here is that possibly many variations of RazorEngine<T> can be passed. I can have RazorTemplateBase, RazorFolderHostTemplateBase, CustomRazorTemplateBase etc. as generic parameters and the Engine property has to reflect that somehow. So, how would I cast that? My first inclination was to use an interface on the engine class and then cast to the interface.  Generally that works, but unfortunately here the engine class is generic and has a few members that require the template type in the member signatures. So while I certainly can implement an interface: public interface IRazorEngine<TBaseTemplateType> it doesn't really help for passing this generically templated object to the template class - I still can't cast it if multiple differently typed versions of the generic type could be passed. I have the exact same issue in that I can't specify a 'generic' generic parameter, since there's no underlying base type that's common. In light of this I decided on using object and the following syntax for the property (and the same would be true for a method parameter): public class RazorTemplateBase :MarshalByRefObject,IDisposable { public object Engine {get;set; } } Now because the Engine property is a non-typed object, when I need to do something with this value, I still have no way to cast it explicitly. What I really would need is: public RazorEngine<> Engine { get; set; } but that's not possible. Dynamic to the Rescue Luckily with the dynamic type this sort of thing can be mitigated fairly easily. For example here's a method that uses the Engine property and uses the well known class interface by simply casting the plain object reference to dynamic and then firing away on the properties and methods of the base template class that are common to all templates:/// <summary> /// Allows rendering a dynamic template from a string template /// passing in a model. This is like rendering a partial /// but providing the input as a /// </summary> public virtual string RenderTemplate(string template,object model) { if (template == null) return string.Empty; // if there's no template markup if(!template.Contains("@")) return template; // use dynamic to get around generic type casting dynamic engine = Engine; string result = engine.RenderTemplate(template, model); if (result == null) throw new ApplicationException("RenderTemplate failed: " + engine.ErrorMessage); return result; } Prior to .NET 4.0  I would have had to use Reflection for this sort of thing which would have a been a heck of a lot more verbose, but dynamic makes this so much easier and cleaner and in this case at least the overhead is negliable since it's a single dynamic operation on an otherwise very complex operation call. Dynamic as  a Bailout Sometimes this sort of thing often reeks of a design flaw, and I agree that in hindsight this could have been designed differently. But as is often the case this particular scenario wasn't planned for originally and removing the generic signatures from the base type would break a ton of other code in the framework. Given the existing fairly complex engine design, refactoring an interface to remove generic types just to make this particular code work would have been overkill. Instead dynamic provides a nice and simple and relatively clean solution. Now if there were many other places where this occurs I would probably consider reworking the code to make this cleaner but given this isolated instance and relatively low profile operation use of dynamic seems a valid choice for me. This solution really works anywhere where you might end up with an inheritance structure that doesn't have a common base or interface that is sufficient. In the example above I know what I'm getting but there's no common base type that I can cast to. All that said, it's a good idea to think about use of dynamic before you rush in. In many situations there are alternatives that can still work with static typing. Dynamic definitely has some overhead compared to direct static access of objects, so if possible we should definitely stick to static typing. In the example above the application already uses dynamics extensively for dynamic page page templating and passing models around so introducing dynamics here has very little additional overhead. The operation itself also fires of a fairly resource heavy operation where the overhead of a couple of dynamic member accesses are not a performance issue. So, what's your experience with dynamic as a bailout mechanism? © Rick Strahl, West Wind Technologies, 2005-2012Posted in CSharp   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

Tom is the Tom behind the AskTom column in Oracle Magazine and is also the author of Expert Oracle Database Architecture (Apress, 2005/2009) among other books Abstract: Big Data The term "big data" draws a lot of attention, but behind the hype there's a simple story. For decades, companies have been making business decisions based on transactional data stored in relational databases. However, beyond that critical data is a potential treasure trove of less structured data: weblogs, social media, email, sensors, and photographs that can be mined for useful information. This presentation will take a look at what Big Data is and means - and Oracle's strategy for handling it Abstract: What are we still doing wrong? I've given many best practices presentations in the last 10 years. I've given many worst practices presentations in the last 10 years. I've seen some things change over the last ten years and many other things stay exactly the same. In this talk - we'll be taking a look at the good and the bad - what we do right and what we continue to do wrong over and over again. We'll look at why "Why" is probably the right initial answer to most any question. We'll look at how we get to "Know what we Know", and why that can be both a help and a hindrance.

• Using jQuery Live instead of jQuery Hover function

  - by hajan

  Let’s say we have a case where we need to create mouseover / mouseout functionality for a list which will be dynamically filled with data on client-side. We can use jQuery hover function, which handles the mouseover and mouseout events with two functions. See the following example: <!DOCTYPE html> <html lang="en"> <head id="Head1" runat="server">     <title>jQuery Mouseover / Mouseout Demo</title>     <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.4.4.js"></script>     <style type="text/css">         .hover { color:Red; cursor:pointer;}     </style>     <script type="text/javascript">         $(function () {             $("li").hover(               function () {                   $(this).addClass("hover");               },               function () {                   $(this).removeClass("hover");               });         });     </script> </head> <body>     <form id="form2" runat="server">     <ul>         <li>Data 1</li>         <li>Data 2</li>         <li>Data 3</li>         <li>Data 4</li>         <li>Data 5</li>         <li>Data 6</li>     </ul>     </form> </body> </html> Now, if you have situation where you want to add new data dynamically... Lets say you have a button to add new item in the list. Add the following code right bellow the </ul> tag <input type="text" id="txtItem" /> <input type="button" id="addNewItem" value="Add New Item" /> And add the following button click functionality: //button add new item functionality $("#addNewItem").click(function (event) {     event.preventDefault();     $("<li>" + $("#txtItem").val() + "</li>").appendTo("ul"); }); The mouse over effect won't work for the newly added items. Therefore, we need to use live or delegate function. These both do the same job. The main difference is that for some cases delegate is considered a bit faster, and can be used in chaining. In our case, we can use both. I will use live function. $("li").live("mouseover mouseout",   function (event) {       if (event.type == "mouseover") $(this).addClass("hover");       else $(this).removeClass("hover");   }); The complete code is: <!DOCTYPE html> <html lang="en"> <head id="Head1" runat="server">     <title>jQuery Mouseover / Mouseout Demo</title>     <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.4.4.js"></script>     <style type="text/css">         .hover { color:Red; cursor:pointer;}     </style>     <script type="text/javascript">         $(function () {             $("li").live("mouseover mouseout",               function (event) {                   if (event.type == "mouseover") $(this).addClass("hover");                   else $(this).removeClass("hover");               });             //button add new item functionality             $("#addNewItem").click(function (event) {                 event.preventDefault();                 $("<li>" + $("#txtItem").val() + "</li>").appendTo("ul");             });         });     </script> </head> <body>     <form id="form2" runat="server">     <ul>         <li>Data 1</li>         <li>Data 2</li>         <li>Data 3</li>         <li>Data 4</li>         <li>Data 5</li>         <li>Data 6</li>     </ul>          <input type="text" id="txtItem" />     <input type="button" id="addNewItem" value="Add New Item" />     </form> </body> </html> So, basically when replacing hover with live, you see we use the mouseover and mouseout names for both events. Check the working demo which is available HERE. Hope this was useful blog for you. Hope it’s helpful.

• Process.Start() and ShellExecute() fails with URLs on Windows 8

  - by Rick Strahl

  Since I installed Windows 8 I've noticed that a number of my applications appear to have problems opening URLs. That is when I click on a link inside of a Windows application, either nothing happens or there's an error that occurs. It's happening both to my own applications and a host of Windows applications I'm running. At first I thought this was an issue with my default browser (Chrome) but after switching the default browser to a few others and experimenting a bit I noticed that the errors occur - oddly enough - only when I run an application as an Administrator. I also tried switching to FireFox and Opera as my default browser and saw exactly the same behavior. The scenario for this is a bit bizarre: Running on Windows 8 Call Process.Start() (or ShellExecute() in Win32 API) with a URL or an HTML file Run 'As Administrator' (works fine under non-elevated user account!) or with UAC off A browser other than Internet Explorer is set as your Default Web Browser Talk about a weird scenario: Something that doesn't work when you run as an Administrator which is supposed to have rights to everything on the system! Instead running under an Admin account - either elevated with a User Account Control prompt or even when running as a full Administrator fails. It appears that this problem does not occur for everyone, but when I looked for a solution to this, I saw quite a few posts in relation to this with no clear resolutions. I have three Windows 8 machines running here in the office and all three of them showed this behavior. Lest you think this is just a programmer's problem - this can affect any software running on your system that needs to run under administrative rights. Try it out Now, in order for this next example to fail, any browser but Internet Explorer has to be your default browser and even then it may not fail depending on how you installed your browser. To see if this is a problem create a small Console application and call Process.Start() with a URL in it:namespace Win8ShellBugConsole { class Program { static void Main(string[] args) { Console.WriteLine("Launching Url..."); Process.Start("http://microsoft.com"); Console.Write("Press any key to continue..."); Console.ReadKey(); Console.WriteLine("\r\n\r\nLaunching image..."); Process.Start(Path.GetFullPath(@"..\..\sailbig.jpg")); Console.Write("Press any key to continue..."); Console.ReadKey(); } } } Compile this code. Then execute the code from Explorer (not from Visual Studio because that may change the permissions). If you simply run the EXE and you're not running as an administrator, you'll see the Web page pop up in the browser as well as the image loading. Now run the same thing with Run As Administrator: Now when you run it you get a nice error when Process.Start() is fired: The same happens if you are running with User Account Control off altogether - ie. you are running as a full admin account. Now if you comment out the URL in the code above and just fire the image display - that works just fine in any user mode. As does opening any other local file type or even starting a new EXE locally (ie. Process.Start("c:\windows\notepad.exe"). All that works, EXCEPT for URLs. The code above uses Process.Start() in .NET but the same happens in Win32 Applications that use the ShellExecute API. In some of my older Fox apps ShellExecute returns an error code of 31 - which is No Shell Association found. What's the Deal? It turns out the problem has to do with the way browsers are registering themselves on Windows. Internet Explorer - being a built-in application in Windows 8 - apparently does this correctly, but other browsers possibly don't or at least didn't at the time I installed them. So even Chrome, which continually updates itself, has a recent version that apparently has this registration issue fixed, I was unable to simply set IE as my default browser then use Chrome to 'Set as Default Browser'. It still didn't work. Neither did using the Set Program Associations dialog which lets you assign what extensions are mapped to by a given application. Each application provides a set of extension/moniker mappings that it supports and this dialog lets you associate them on a system wide basis. This also did not work for Chrome or any of the other browsers at first. However, after repeated retries here eventually I did manage to get FireFox to work, but not any of the others. What Works? Reinstall the Browser In the end I decided on the hard core pull the plug solution: Totally uninstall and re-install Chrome in this case. And lo and behold, after reinstall everything was working fine. Now even removing the association for Chrome, switching to IE as the default browser and then back to Chrome works. But, even though the version of Chrome I was running before uninstalling and reinstalling is the same as I'm running now after the reinstall now it works. Of course I had to find out the hard way, before Richard commented with a note regarding what the issue is with Chrome at least: http://code.google.com/p/chromium/issues/detail?id=156400 As expected the issue is a registration issue - with keys not being registered at the machine level. Reading this I'm still not sure why this should be a problem - an elevated account still runs under the same user account (ie. I'm still rickstrahl even if I Run As Administrator), so why shouldn't an app be able to read my Current User registry hive? And also that doesn't quite explain why if I register the extensions using Run As Administrator in Chrome when using Set as Default Browser). But in the end it works… Not so fast It's now a couple of days later and still there are some oddball problems although this time they appear to be purely Chrome issues. After the reinstall Chrome seems to pop up properly with ShellExecute() calls both in regular user and Admin mode. However, it now looks like Chrome is actually running two completely separate user profiles for each. For example, when I run Visual Studio in Admin mode and go to View in browser, Chrome complains that it was installed in Admin mode and can't launch (WTF?). Then you retry a few times later and it ends up working. When launched that way some of the plug-ins installed don't show up with the effect that sometimes they're visible sometimes they're not. Also Chrome seems to loose my configuration and Google sign in between sessions now, presumably when switching user modes. Add-ins installed in admin mode don't show up in user mode and vice versa. Ah, this is lovely. Did I mention that I freaking hate UAC precisely because of this kind of bullshit. You can never tell exactly what account your app is running under, and apparently apps also have a hard time trying to put data into the right place that works for both scenarios. And as my recent post on using Windows Live accounts shows it's yet another level of abstraction ontop of the underlying system identity that can cause all sort of small side effect headaches like this. Hopefully, most of you are skirting this issue altogether - having installed more recent versions of your favorite browsers. If not, hopefully this post will take you straight to reinstallation to fix this annoying issue.© Rick Strahl, West Wind Technologies, 2005-2012Posted in Windows  .NET   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Physical Directories vs. MVC View Paths

  - by Rick Strahl

  This post falls into the bucket of operator error on my part, but I want to share this anyway because it describes an issue that has bitten me a few times now and writing it down might keep it a little stronger in my mind. I've been working on an MVC project the last few days, and at the end of a long day I accidentally moved one of my View folders from the MVC Root Folder to the project root. It must have been at the very end of the day before shutting down because tests and manual site navigation worked fine just before I quit for the night. I checked in changes and called it a night. Next day I came back, started running the app and had a lot of breaks with certain views. Oddly custom routes to these controllers/views worked, but stock /{controller}/{action} routes would not. After a bit of spelunking I realized that "Hey one of my View Folders is missing", which made some sense given the error messages I got. I looked in the recycle bin - nothing there, so rather than try to figure out what the hell happened, just restored from my last SVN checkin. At this point the folders are back… but… view access  still ends up breaking for this set of views. Specifically I'm getting the Yellow Screen of Death with: CS0103: The name 'model' does not exist in the current context Here's the full error: Server Error in '/ClassifiedsWeb' Application. Compilation ErrorDescription: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.Compiler Error Message: CS0103: The name 'model' does not exist in the current contextSource Error: Line 1: @model ClassifiedsWeb.EntryViewModel Line 2: @{ Line 3: ViewBag.Title = Model.Entry.Title + " - " + ClassifiedsBusiness.App.Configuration.ApplicationName; Source File: c:\Projects2010\Clients\GorgeNet\Classifieds\ClassifiedsWeb\Classifieds\Show.cshtml    Line: 1 Compiler Warning Messages: Show Detailed Compiler Output: Show Complete Compilation Source: Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.272 Here's what's really odd about this error: The views now do exist in the /Views/Classifieds folder of the project, but it appears like MVC is trying to execute the views directly. This is getting pretty weird, man! So I hook up some break points in my controllers to see if my controller actions are getting fired - and sure enough it turns out they are not - but only for those views that were previously 'lost' and then restored from SVN. WTF? At this point I'm thinking that I must have messed up one of the config files, but after some more spelunking and realizing that all the other Controller views work, I give up that idea. Config's gotta be OK if other controllers and views are working. Root Folders and MVC Views don't mix As I mentioned the problem was the fact that I inadvertantly managed to drag my View folder to the root folder of the project. Here's what this looks like in my FUBAR'd project structure after I copied back /Views/Classifieds folder from SVN: There's the actual root folder in the /Views folder and the accidental copy that sits of the root. I of course did not notice the /Classifieds folder at the root because it was excluded and didn't show up in the project. Now, before you call me a complete idiot remember that this happened by accident - an accidental drag probably just before shutting down for the night. :-) So why does this break? MVC should be happy with views in the /Views/Classifieds folder right? While MVC might be happy, IIS is not. The fact that there is a physical folder on disk takes precedence over MVC's routing. In other words if a URL exists that matches a route the pysical path is accessed first. What happens here is that essentially IIS is trying to execute the .cshtml pages directly without ever routing to the Controller methods. In the error page I showed above my clue should have been that the view was served as: c:\Projects2010\Clients\GorgeNet\Classifieds\ClassifiedsWeb\Classifieds\Show.cshtml rather than c:\Projects2010\Clients\GorgeNet\Classifieds\ClassifiedsWeb\Views\Classifieds\Show.cshtml But of course I didn't notice that right away, just skimming to the end and looking at the file name. The reason that /classifieds/list actually fires that file is that the ASP.NET Web Pages engine looks for physical files on disk that match a path. IOW, when calling Web Pages you drop the .cshtml off the Razor page and IIS will serve that just fine. So: /classifieds/list looks and tries to find /classifieds/list.cshtml and executes that script. And that is exactly what's happening. Web Pages is trying to execute the .cshtml file and it fails because Web Pages knows nothing about the @model tag which is an MVC specific template extension. This is why my breakpoints in the controller methods didn't fire and it also explains why the error mentions that the @model key word is invalid (@model is an MVC provided template enhancement to the Razor Engine). The solution of course is super simple: Delete the accidentally created root folder and the problem is solved. Routing and Physical Paths I've run into problems with this before actually. In the past I've had a number of applications that had a physical /Admin folder which also would conflict with an MVC Admin controller. More than once I ended up wondering why the index route (/Admin/) was not working properly. If a physical /Admin folder exists /Admin will not route to the Index action (or whatever default action you have set up, but instead try to list the directory or show the default document in the folder. The only way to force the index page through MVC is to explicitly use /Admin/Index. Makes perfect sense once you realize the physical folder is there, but that's easy to forget in an MVC application. As you might imagine after a few times of running into this I gave up on the Admin folder and moved everything into MVC views to handle those operations. Still it's one of those things that can easily bite you, because the behavior and error messages seem to point at completely different  problems. Moral of the story is: If you see routing problems where routes are not reaching obvious controller methods, always check to make sure there's isn't a physical path being mapped by IIS instead. That way you won't feel stupid like I did after trying a million things for about an hour before discovering my sloppy mousing behavior :-)© Rick Strahl, West Wind Technologies, 2005-2012Posted in MVC   IIS7   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• HTML5 Input type=date Formatting Issues

  - by Rick Strahl

  One of the nice features in HTML5 is the abililty to specify a specific input type for HTML text input boxes. There a host of very useful input types available including email, number, date, datetime, month, number, range, search, tel, time, url and week. For a more complete list you can check out the MDN reference. Date input types also support automatic validation which can be useful in some scenarios but maybe can get in the way at other times. One of the more common input types, and one that can most benefit of a custom UI for selection is of course date input. Almost every application could use a decent date representation and HTML5's date input type seems to push into the right direction. It'd be nice if you could just say:<form action="DateTest.html"> <label for="FromDate">Enter a Date:</label> <input type="date" id="FromDate" name="FromDate" value="11/08/2012" class="date" /> <hr /> <input type="submit" id="btnSubmit" name="btnSubmit" value="Save Date" class="smallbutton" /> </form> but if you'd expect to just work, you're likely to be pretty disappointed. Problem #1: Browser Support For starters there's browser support. Out of the major browsers only the latest versions of WebKit and Opera based browsers seem to support date input. Neither FireFox, nor any version of Internet Explorer (including the new touch enabled IE10 in Windows RT) support input type=date. Browser support is an issue, but it would be OK if it wasn't for problem #2. Problem #2: Date Formatting If you look at my date input from before:<input type="date" id="FromDate" name="FromDate" value="11/08/2012" class="date" /> You can see that my date is formatted in local date format (ie. en-us). Now when I run this sadly the form that comes up in Chrome (and also iOS mobile browsers) comes up like this: Chrome isn't recognizing my local date string. Instead it's expecting my date format to be provided in ISO 8601 format which is: 2012-11-08 So if I change the date input field to:<input type="date" id="FromDate" name="FromDate" value="2012-10-08" class="date" /> I correctly get the date field filled in: Also when I pick a date with the DatePicker the date value is also returned is also set to the ISO date format. Yet notice how the date is still formatted to the local date time format (ie. en-US format). So if I pick a new date: and then save, the value field is set back to: 2012-11-15 using the ISO format. The same is true for Opera and iOS browsers and I suspect any other WebKit style browser and their date pickers. So to summarize input type=date: Expects ISO 8601 format dates to display intial values Sets selected date values to ISO 8601 Now what? This would sort of make sense, if all browsers supported input type=date. It'd be easy because you could just format dates appropriately when you set the date value into the control by applying the appropriate culture formatting (ie. .ToString("yyyy-MM-dd") ). .NET is actually smart enough to pick up the date on the other end for modelbinding when ISO 8601 is used. For other environments this might be a bit more tricky. input type=date is clearly the way to go forward. Date controls implemented in HTML are going the way of the dodo, given the intricacies of mobile platforms and scaling for both desktop and mobile. I've been using jQuery UI Datepicker for ages but once going to mobile, that's no longer an option as the control doesn't scale down well for mobile apps (at least not without major re-styling). It also makes a lot of sense for the browser to provide this functionality - creating a consistent date input experience across apps only makes sense, which is why I find it baffling that neither FireFox nor IE 10 deign it necessary to support date input natively. The problem is that a large number of even the latest and greatest browsers don't support this. So now you're stuck with not knowing what date format you have to serve since neither the local format, nor the ISO format works in all cases. For my current app I just broke down and used the ISO format and so I'll live with the non-local date format. <input type="date" id="ToDate" name="ToDate" value="2012-11-08" class="date"/> Here's what this looks like on Chrome: Here's what it looks like on my iPhone: Both Chrome and the phone do this the way it should be. For the phone especially this demonstrates why we'd want this - the built-in date picker there certainly beats manually trying to edit the date using finger gymnastics, and it's one of the easiest ways to pick a date I can think of (ie. easier to use than your typical date picker). Finally here's what the date looks like in FireFox: Certainly this is not the ideal date format, but it's clear enough I suppose. If users enter a date in local US format and that works as well (but won't work for other locales). It'll have to do. Over time one can only hope that other browsers will finally decide to implement this functionality natively to provide a unique experience. Until then, incomplete solutions it is.

• Prevent your Silverlight XAP file from caching in your browser.

  - by mbcrump

  If you work with Silverlight daily then you have run into this problem. Your XAP file has been cached in your browser and you have to empty your browser cache to resolve it. If your using Google Chrome then you typically do the following: Go to Options –> Clear Browsing History –> Empty the Cache and finally click Clear Browsing data. As you can see, this is a lot of unnecessary steps. It is even worse when you have a customer that says, “I can’t see the new features you just implemented!” and you realize it’s a cached xap problem.  I have been struggling with a way to prevent my XAP file from caching inside of a browser for a while now and decided to implement the following solution. If the Visual Studio Debugger is attached then add a unique query string to the source param to force the XAP file to be refreshed. If the Visual Studio Debugger is not attached then add the source param as Visual Studio generates it. This is also in case I forget to remove the above code in my production environment. I want the ASP.NET code to be inline with my .ASPX page. (I do not want a separate code behind .cs page or .vb page attached to the .aspx page.) Below is an example of the hosting code generated when you create a new Silverlight project. As a quick refresher, the hard coded param name = “source” specifies the location of your XAP file.  <form id="form1" runat="server" style="height:100%"> <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="ClientBin/SilverlightApplication2.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50826.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </form> We are going to use a little bit of inline ASP.NET to generate the param name = source dynamically to prevent the XAP file from caching. Lets look at the completed solution: <form id="form1" runat="server" style="height:100%"> <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <% string strSourceFile = @"ClientBin/SilverlightApplication2.xap"; string param; if (System.Diagnostics.Debugger.IsAttached) //Debugger Attached - Refresh the XAP file. param = "<param name=\"source\" value=\"" + strSourceFile + "?" + DateTime.Now.Ticks + "\" />"; else { //Production Mode param = "<param name=\"source\" value=\"" + strSourceFile + "\" />"; } Response.Write(param); %> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50826.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </form> We add the location to our XAP file to strSourceFile and if the debugger is attached then it will append DateTime.Now.Ticks to the XAP file source and force the browser to download the .XAP. If you view the page source of your Silverlight Application then you can verify it worked properly by looking at the param name = “source” tag as shown below. <param name="source" value="ClientBin/SilverlightApplication2.xap?634299001187160148" /> If the debugger is not attached then it will use the standard source tag as shown below. <param name="source" value="ClientBin/SilverlightApplication2.xap"/> At this point you may be asking, How do I prevent my XAP file from being cached on my production app? Well, you have two easy options: 1) I really don’t recommend this approach but you can force the XAP to be refreshed everytime with the following code snippet.  <param name="source" value="ClientBin/SilverlightApplication2.xap?<%=Guid.NewGuid().ToString() %>"/> NOTE: You could also substitute the “Guid.NewGuid().ToString() for anything that create a random field. (I used DateTime.Now.Ticks earlier). 2) Another solution that I like even better involves checking the XAP Creation Date and appending it to the param name = source. This method was described by Lars Holm Jenson. <% string strSourceFile = @"ClientBin/SilverlightApplication2.xap"; string param; if (System.Diagnostics.Debugger.IsAttached) param = "<param name=\"source\" value=\"" + strSourceFile + "\" />"; else { string xappath = HttpContext.Current.Server.MapPath(@"") + @"\" + strSourceFile; DateTime xapCreationDate = System.IO.File.GetLastWriteTime(xappath); param = "<param name=\"source\" value=\"" + strSourceFile + "?ignore=" + xapCreationDate.ToString() + "\" />"; } Response.Write(param); %> As you can see, this problem has been solved. It will work with all web browsers and stubborn proxy servers that are caching your .XAP. If you enjoyed this article then check out my blog for others like this.

• Modern/Metro Internet Explorer: What were they thinking???

  - by Rick Strahl

  As I installed Windows 8.1 last week I decided that I really should take a closer look at Internet Explorer in the Modern/Metro environment again. Right away I ran into two issues that are real head scratchers to me.Modern Split Windows don't resize Viewport but Zoom OutThis one falls in the "WTF, really?" department: It looks like Modern Internet Explorer's Modern doesn't resize the browser window as every other browser (including IE 11 on the desktop) does, but rather tries to adjust the zoom to the width of the browser. This means that if you use the Modern IE browser and you split the display between IE and another application, IE will be zoomed out, with text becoming much, much smaller, rather than resizing the browser viewport and adjusting the pixel width as you would when a browser window is typically resized.Here's what I'm talking about in a couple of pictures. First here's the full screen Internet Explorer version (this shot is resized down since it's full screen at 1080p, click to see the full image):This brings up the first issue which is: On the desktop who wants to browse a site full screen? Most sites aren't fully optimized for 1080p widescreen experience and frankly most content that wide just looks weird. Even in typical 10" resolutions of 1280 width it's weird to look at things this way. At least this issue can be worked around with @media queries and either constraining the view, or adding additional content to make use of the extra space. Still running a desktop browser full screen is not optimal on a desktop machine - ever.Regardless, this view, while oversized, is what I expect: Everything is rendered in the right ratios, with font-size and the responsive design styling properly respected.But now look what happens when you split the desktop windows and show half desktop and have modern IE (this screen shot is not resized but cropped - this is actual size content as you can see in the cropped Twitter window on the right half of the screen):What's happening here is that IE is zooming out of the content to make it fit into the smaller width, shrinking the content rather than resizing the viewport's pixel width. In effect it looks like the pixel width stays at 1080px and the viewport expands out height-wise in response resulting in some crazy long portrait view.There goes responsive design - out the window literally. If you've built your site using @media queries and fixed viewport sizes, Internet Explorer completely screws you in this split view. On my 1080p monitor, the site shown at a little under half width becomes completely unreadable as the fonts are too small and break up. As you go into split view and you resize the window handle the content of the browser gets smaller and smaller (and effectively longer and longer on the bottom) effectively throwing off any responsive layout to the point of un-readability even on a big display, let alone a small tablet screen.What could POSSIBLY be the benefit of this screwed up behavior? I checked around a bit trying different pages in this shrunk down view. Other than the Microsoft home page, every page I went to was nearly unreadable at a quarter width. The only page I found that worked 'normally' was the Microsoft home page which undoubtedly is optimized just for Internet Explorer specifically.Bottom Address Bar opaquely overlays ContentAnother problematic feature for me is the browser address bar on the bottom. Modern IE shows the status bar opaquely on the bottom, overlaying the content area of the Web Page - until you click on the page. Until you do though, the address bar overlays the bottom content solidly. And not just a little bit but by good sizable chunk.In the application from the screen shot above I have an application toolbar on the bottom and the IE Address bar completely hides that bottom toolbar when the page is first loaded, until the user clicks into the content at which point the address bar shrinks down to a fat border style bar with a … on it. Toolbars on the bottom are pretty common these days, especially for mobile optimized applications, so I'd say this is a common use case. But even if you don't have toolbars on the bottom maybe there's other fixed content on the bottom of the page that is vital to display. While other browsers often also show address bars and then later hide them, these other browsers tend to resize the viewport when the address bar status changes, so the content can respond to the size change. Not so with Modern IE. The address bar overlays content and stays visible until content is clicked. No resize notification or viewport height change is sent to the browser.So basically Internet Explorer is telling me: "Our toolbar is more important than your content!" - AND gives me no chance to re-act to that behavior. The result on this page/application is that the user sees no actionable operations until he or she clicks into the content area, which is terrible from a UI perspective as the user has no idea what options are available on initial load.It's doubly confounding in that IE is running in full screen mode and has an the entire height of the screen at its disposal - there's plenty of real estate available to not require this sort of hiding of content in the first place. Heck, even Windows Phone with its more constrained size doesn't hide content - in fact the address bar on Windows Phone 8 is always visible.What were they thinking?Every time I use anything in the Modern Metro interface in Windows 8/8.1 I get angry.  I can pretty much ignore Metro/Modern for my everyday usage, but unfortunately with Internet Explorer in the modern shell I have to live with, because there will be users using it to access my sites. I think it's inexcusable by Microsoft to build such a crappy shell around the browser that impacts the actual usability of Web content. In both of the cases above I can only scratch my head at what could have possibly motivated anybody designing the UI for the browser to make these screwed up choices, that manipulate the content in a totally unmaintainable way.© Rick Strahl, West Wind Technologies, 2005-2013Posted in Windows  HTML5   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Using JQuery tabs in an HTML 5 page

  - by nikolaosk

  In this post I will show you how to create a simple tabbed interface using JQuery,HTML 5 and CSS.Make sure you have downloaded the latest version of JQuery (minified version) from http://jquery.com/download.Please find here all my posts regarding JQuery.Also have a look at my posts regarding HTML 5.In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. Let me move on to the actual example.This is the sample HTML 5 page<!DOCTYPE html><html lang="en">  <head>    <title>Liverpool Legends</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">    <script type="text/javascript" src="jquery-1.8.2.min.js"> </script>     <script type="text/javascript" src="tabs.js"></script>       </head>  <body>    <header>        <h1>Liverpool Legends</h1>    </header>     <section id="tabs">        <ul>            <li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=9143136#first-tab">Defenders</a></li>            <li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=9143136#second-tab">Midfielders</a></li>            <li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=9143136#third-tab">Strikers</a></li>        </ul>   <div id="first-tab">     <h3>Liverpool Defenders</h3>     <p> The best defenders that played for Liverpool are Jamie Carragher, Sami Hyypia , Ron Yeats and Alan Hansen.</p>   </div>   <div id="second-tab">     <h3>Liverpool Midfielders</h3>     <p> The best midfielders that played for Liverpool are Kenny Dalglish, John Barnes,Ian Callaghan,Steven Gerrard and Jan Molby.        </p>   </div>   <div id="third-tab">     <h3>Liverpool Strikers</h3>     <p>The best strikers that played for Liverpool are Ian Rush,Roger Hunt,Robbie Fowler and Fernando Torres.<br/>      </p>   </div> </div></section>            <footer>        <p>All Rights Reserved</p>      </footer>     </body>  </html>  This is very simple HTML markup. I have styled this markup using CSS.The contents of the style.css file follow* {    margin: 0;    padding: 0;}header{font-family:Tahoma;font-size:1.3em;color:#505050;text-align:center;}#tabs {    font-size: 0.9em;    margin: 20px 0;}#tabs ul {    float: left;    background: #777;    width: 260px;    padding-top: 24px;}#tabs li {    margin-left: 8px;    list-style: none;}* html #tabs li {    display: inline;}#tabs li, #tabs li a {    float: left;}#tabs ul li.active {    border-top:2px red solid;    background: #15ADFF;}#tabs ul li.active a {    color: #333333;}#tabs div {    background: #15ADFF;    clear: both;    padding: 15px;    min-height: 200px;}#tabs div h3 {    margin-bottom: 12px;}#tabs div p {    line-height: 26px;}#tabs ul li a {    text-decoration: none;    padding: 8px;    color:#0b2f20;    font-weight: bold;}footer{background-color:#999;width:100%;text-align:center;font-size:1.1em;color:#002233;}There are some CSS rules that style the various elements in the HTML 5 file. These are straight-forward rules. The JQuery code lives inside the tabs.js file $(document).ready(function(){$('#tabs div').hide();$('#tabs div:first').show();$('#tabs ul li:first').addClass('active'); $('#tabs ul li a').click(function(){$('#tabs ul li').removeClass('active');$(this).parent().addClass('active');var currentTab = $(this).attr('href');$('#tabs div').hide();$(currentTab).show();return false;});}); I am using some of the most commonly used JQuery functions like hide , show, addclass , removeClass I hide and show the tabs when the tab becomes the active tab. When I view my page I get the following result Hope it helps!!!!!

• Using Apache FOP from .NET level

  - by Lukasz Kurylo

  In one of my previous posts I was talking about FO.NET which I was using to generate a pdf documents from XSL-FO. FO.NET is one of the .NET ports of Apache FOP. Unfortunatelly it is no longer maintained. I known it when I decidec to use it, because there is a lack of available (free) choices for .NET to render a pdf form XSL-FO. I hoped in this implementation I will find all I need to create a pdf file with my really simple requirements. FO.NET is a port from some old version of Apache FOP and I found really quickly that there is a lack of some features that I needed, like dotted borders, double borders or support for margins. So I started to looking for some alternatives. I didn’t try the NFOP, another port of Apache FOP, because I found something I think much more better, the IKVM.NET project.   IKVM.NET it is not a pdf renderer. So what it is? From the project site:   IKVM.NET is an implementation of Java for Mono and the Microsoft .NET Framework. It includes the following components: a Java Virtual Machine implemented in .NET a .NET implementation of the Java class libraries tools that enable Java and .NET interoperability   In the simplest form IKVM.NET allows to use a Java code library in the C# code and vice versa.   I tried to use an Apache FOP, the best I think open source pdf –> XSL-FO renderer written in Java from my project written in C# using an IKVM.NET and it work like a charm. In the rest of the post I want to show, how to prepare a .NET *.dll class library from Apache FOP *.jar’s with IKVM.NET and generate a simple Hello world pdf document.   To start playing with IKVM.NET and Apache FOP we need to download their packages: IKVM.NET Apache FOP and then unpack them.   From the FOP directory copy all the *.jar’s files from lib and build catalogs to some location, e.g. d:\fop. Second step is to build the *.dll library from these files. On the console execute the following comand:   ikvmc –target:library –out:d:\fop\fop.dll –recurse:d:\fop   The ikvmc is located in the bin subdirectory where you unpacked the IKVM.NET. You must execute this command from this catalog, add this path to the global variable PATH or specify the full path to the bin subdirectory.   In no error occurred during this process, the fop.dll library should be created. Right now we can create a simple project to test if we can create a pdf file.   So let’s create a simple console project application and add reference to the fop.dll and the IKVM dll’s: IKVM.OpenJDK.Core and IKVM.OpenJDK.XML.API.   Full code to generate a pdf file from XSL-FO template:   static void Main(string[] args)         {             //initialize the Apache FOP             FopFactory fopFactory = FopFactory.newInstance();               //in this stream we will get the generated pdf file             OutputStream o = new DotNetOutputMemoryStream();             try             {                 Fop fop = fopFactory.newFop("application/pdf", o);                 TransformerFactory factory = TransformerFactory.newInstance();                 Transformer transformer = factory.newTransformer();                   //read the template from disc                 Source src = new StreamSource(new File("HelloWorld.fo"));                 Result res = new SAXResult(fop.getDefaultHandler());                 transformer.transform(src, res);             }             finally             {                 o.close();             }             using (System.IO.FileStream fs = System.IO.File.Create("HelloWorld.pdf"))             {                 //write from the .NET MemoryStream stream to disc the generated pdf file                 var data = ((DotNetOutputMemoryStream)o).Stream.GetBuffer();                 fs.Write(data, 0, data.Length);             }             Process.Start("HelloWorld.pdf");             System.Console.ReadLine();         }   Apache FOP be default using a Java’s Xalan to work with XML files. I didn’t find a way to replace this piece of code with equivalent from .NET standard library. If any error or warning will occure during generating the pdf file, on the console will ge shown, that’s why I inserted the last line in the sample above. The DotNetOutputMemoryStream this is my wrapper for the Java OutputStream. I have created it to have the possibility to exchange data between the .NET <-> Java objects. It’s implementation:   class DotNetOutputMemoryStream : OutputStream     {         private System.IO.MemoryStream ms = new System.IO.MemoryStream();         public System.IO.MemoryStream Stream         {             get             {                 return ms;             }         }         public override void write(int i)         {             ms.WriteByte((byte)i);         }         public override void write(byte[] b, int off, int len)         {             ms.Write(b, off, len);         }         public override void write(byte[] b)         {             ms.Write(b, 0, b.Length);         }         public override void close()         {             ms.Close();         }         public override void flush()         {             ms.Flush();         }     } The last thing we need, this is the HelloWorld.fo template.   <?xml version="1.0" encoding="utf-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">   <fo:layout-master-set>     <fo:simple-page-master master-name="simple"                   page-height="29.7cm"                   page-width="21cm"                   margin-top="1.8cm"                   margin-bottom="0.8cm"                   margin-left="1.6cm"                   margin-right="1.2cm">       <fo:region-body margin-top="3cm"/>       <fo:region-before extent="3cm"/>       <fo:region-after extent="1.5cm"/>     </fo:simple-page-master>   </fo:layout-master-set>   <fo:page-sequence master-reference="simple">     <fo:flow flow-name="xsl-region-body">       <fo:block font-size="18pt" color="black" text-align="center">         Hello, World!       </fo:block>     </fo:flow>   </fo:page-sequence> </fo:root>   I’m not going to explain how how this template is created, because this will be covered in the near future posts.   Generated pdf file should look that:

• Sorting the columns of an HTML table using JQuery

  - by nikolaosk

  In this post I will show you how easy is to sort the columns of an HTML table. I will use an external library,called Tablesorter which makes life so much easier for developers. ?here are other posts in my blog regarding JQuery.You can find them all here. You can find another post regarding HTML tables and JQuery here. We will demonstrate this with a step by step example. I will use Visual Studio 2012 Ultimate. You can also use Visual Studio 2012 Express Edition. You can also use VS 2010 editions.   1) Launch Visual Studio. Create an ASP.Net Empty Web application. Choose an appropriate name for your application. 2) Add a web form, default.aspx page to the application. 3) Add a table from the HTML controls tab control (from the Toolbox) on the default.aspx page 4) Now we need to download the JQuery library. Please visit the http://jquery.com/ and download the minified version.Then we need to download the Tablesorter JQuery plugin. Please donwload it, here. 5) We need to reference the JQuery library and the external JQuery Plugin. In the head section ? add the following lines.   <script src="jquery-1_8_2_min.js" type="text/javascript"></script>  <script src="jquery.tablesorter.js" type="text/javascript"></script>6) We need to type the HTML markup, the HTML table and its columns <body>    <form id="form1" runat="server">    <div>        <h1>Liverpool Legends</h1>        <table style="width: 50%;" border="1" cellpadding="10" cellspacing ="10" class="liverpool">            <thead>                <tr><th>Defenders</th><th>MidFielders</th><th>Strikers</th></tr>            </thead>            <tbody>            <tr>                <td>Alan Hansen</td>                <td>Graeme Souness</td>                <td>Ian Rush</td>            </tr>            <tr>                <td>Alan Kennedy</td>                <td>Steven Gerrard</td>                <td>Michael Owen</td>            </tr>            <tr>                <td>Jamie Garragher</td>                <td>Kenny Dalglish</td>                <td>Robbie Fowler</td>            </tr>            <tr>                <td>Rob Jones</td>                <td>Xabi Alonso</td>                <td>Dirk Kuyt</td>            </tr>                </tbody>        </table>            </div>    </form></body> 7) Inside the head section we also write the simple JQuery code.   <script type="text/javascript"> $(document).ready(function() { $('.liverpool').tablesorter(); }); </script> 8) Run your application.This is how the HTML table looks before the table is sorted on the basis of the selected column.   9) Now I will click on the Midfielders header.Have a look at the picture below  Tablesorter is an excellent JQuery plugin that makes sorting HTML tables a piece of cake. Hope it helps!!!

• Modifying a HTML page to fix several "bugs" add a function to next/previous on a option dropdown

  - by Dennis Sylvian

  SOF, I've got a few problems plaguing me at the moment and am wondering if anyone could assist me with them. I'm trying to get Next Class | Previous Class to act as buttons so that when Next Class is clicked it will go to the next item in the dropdown list and for previous it would go to back one. There used to be a scroll bar that allowed me to scroll the main window left and right, it's missing because (I think it was to do with the scroll left and scroll right function) The footer at the bottom doesn't show correctly on mobile devices; for some reason it appears completely differently to as it does on a computer. The "bar" practically and the Scroll Left and Scroll buttons don't appear at all on mobile devices. The scroll left button is unable to be clicked for some reason, I'm unsure what I've done wrong. Refreshing the page resets the horizontal scroll position to far left (I'm pretty sure this relates to the scroll bar) I want to also find a way so that on mobile devices the the header will not show the placeholder image, however I can't work out what CSS media tag(s) I should be using.

• FCKEditor doesn't set Value property on postback!

  - by Shaul

  I'm using FCKEditor on my asp.net web page. It appears beautifully, and the editor looks really good on the front end. Only problem is, the .Value property is not being set on the postback. No matter what changes the user makes to the value of the control on the page, when I click "Submit", the .Value property remains blank. I have Googled for other solutions, and most of them are of the variety where there's some conflict with Ajax, such as this and this. My problem is not solved by these solutions; it's much more fundamental than that. I'm not doing anything to do with Ajax; I'm just a simple asp.net newbie with a simple web form, and the value property is not being set on postback, not in IE and not in FF. It appears that at least one other person has had this problem, but no solution yet. Any ideas? Thanks! New information: I tried this out on a "hello world" test web site - and the test web site works 100%. There is obviously a problem on my page, but I have no idea where to begin tracking this down. Here's the markup of my page, in case anyone can see anything obvious that my newbie eyes can't: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="EmailTemplateEditForm.aspx.vb" Inherits="EEI_App.EmailTemplateEditForm" %> <%@ Register Assembly="FredCK.FCKeditorV2" Namespace="FredCK.FCKeditorV2" TagPrefix="FCKeditorV2" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>EEI - Email Template</title> <link rel="stylesheet" href="EEI.css"> <script language="javascript" id="jssembleWare" src="sembleWare.js"></script> <style type="text/css"> .style1 { height: 251px; } .style2 { width: 2%; height: 251px; } .style3 { height: 490px; } </style> </head> <body> <form id="form1" runat="server"> <%@ register src="header.ascx" tagname="header" tagprefix="uc1" %> <%@ register src="footer.ascx" tagname="footer" tagprefix="uc1" %> <uc1:header ID="header1" runat="server" /> <!-- main content area --> <div class="content"> <!-- title of the page --> <div class="boxheader"> Email Template </div> <div class="standardbox"> <!-- Start Page Main Contents--> <!-- error messages --> <div class="errorbox"> <asp:Label ID="lblError" CssClass="ErrorControlStyle" runat="server" EnableViewState="False" Width="100%"></asp:Label> </div> <table class="contenttable"> <tr> <td align="left" valign="top" class="style3"> <div class="actionbox"> <div class="navheadertitle"> Navigation</div> <ul> <li> <asp:LinkButton ID="btnSubmit" CssClass="LinkButtonStyle" runat="server">Submit</asp:LinkButton> </li> <li> <asp:LinkButton ID="btnCancel" CssClass="LinkButtonStyle" runat="server" CausesValidation="false">Cancel</asp:LinkButton> </li> </ul> </div> </td> <td align="left" valign="top" class="style3"> <p> </p> <table> <tr class="MCRSFieldRow"> <td class="MCRSFieldLabelCell"> <asp:Label ID="lblEmailTemplate_TemplateName" CssClass="LabelStyle" runat="server" Width="175">Template Name</asp:Label> </td> <td class="MCRSFieldEditCell"> <asp:TextBox ID="txtEmailTemplate_TemplateName" CssClass="TextBoxStyle" runat="server" Width="100%"></asp:TextBox> </td> <td class="MCRSFieldLabelCell"> <asp:Label ID="lblEmailTemplate_TemplateType" CssClass="LabelStyle" runat="server" Width="175">Template Type</asp:Label> </td> <td class="MCRSFieldEditCell"> <asp:RadioButtonList ID="rblEmailTemplate_TemplateType" CssClass="RadioButtonListStyle" runat="server" RepeatColumns="1" RepeatDirection="Horizontal" Width="135px"> <asp:ListItem Value="1">Cover Letter</asp:ListItem> <asp:ListItem Value="2">Email</asp:ListItem> </asp:RadioButtonList> </td> <td class="MCRSRowRightCell"> &nbsp; </td> </tr> <tr class="MCRSFieldRow"> <td class="MCRSFieldLabelCell"> Composition Date </td> <td class="MCRSFieldEditCell"> <asp:Label ID="lblEmailTemplate_CompositionDate" CssClass="ElementLabelStyle" runat="server" Width="175"></asp:Label> </td> <td class="MCRSFieldLabelCell"> Last Used Date </td> <td class="MCRSFieldEditCell"> <asp:Label ID="lblEmailTemplate_LastUsedDate" CssClass="ElementLabelStyle" runat="server" Width="175"></asp:Label> </td> <td class="MCRSRowRightCell"> &nbsp; </td> </tr> <tr class="MCRSFieldRow"> <td class="MCRSFieldLabelCell"> Composed By </td> <td class="MCRSFieldEditCell" colspan="3"> <asp:Label ID="lblPerson_FirstNames" CssClass="ElementLabelStyle" runat="server"></asp:Label> <asp:Label ID="lblPerson_LastName" CssClass="ElementLabelStyle" runat="server"></asp:Label> </td> <td class="MCRSRowRightCell"> &nbsp; </td> </tr> <tr class="MCRSFieldRow"> <td class="MCRSFieldLabelCell"> <asp:Label ID="lblEmailTemplate_Subject" CssClass="LabelStyle" runat="server" Width="175">Subject</asp:Label> </td> <td class="MCRSFieldEditCell" colspan="3"> <asp:TextBox ID="txtEmailTemplate_Subject" CssClass="TextBoxStyle" runat="server" Width="100%"></asp:TextBox> </td> <td class="MCRSRowRightCell"> &nbsp; </td> </tr> <tr class="MCRSFieldRow"> <td class="style1"> <asp:Label ID="lblEmailTemplate_Body" CssClass="LabelStyle" runat="server" Width="175">Body</asp:Label> </td> <td class="style1" colspan="3"> <FCKeditorV2:FCKeditor ID="FCKeditor1" runat="server" Height="500px"> </FCKeditorV2:FCKeditor> </td> <td class="style2"> &nbsp; </td> </tr> </table> </td> </tr> </table> </div> <p> <a class="InputButtonStyle" href="#_swTopOfPage">Top of Page</a> </p> </div> <uc1:footer ID="footer1" runat="server" /> <p> <asp:TextBox ID="txtEmailTemplate_Body" CssClass="TextAreaStyle" Rows="4" runat="server" Width="100%" Height="16px" Visible="False"></asp:TextBox> </p> </form> </body> </html>

• How to Use Images as Navigation with innerfade Slideshow?

  - by Katie

  I am very new to JavaScript and only have the most basic understanding of how it works, so please bear with me. :) I'm using the jquery.innerfade.js script to create a slideshow with fade transitions for a website I'm developing, and I have added navigation buttons (which are set as background-images) that navigate between the “slides”. The navigation buttons have three states: default/off, hover, and on (each state is a separate image). I created a separate JavaScript document to set the buttons to “on” when they are clicked. The “hover” state is achieved through the CSS. Both the slideshow and the navigation buttons work well. There is just one thing I want to add: I would like the appropriate navigation button to display as “on” while the related “slide” is “playing”. Here's the HTML: <div id="mainFeature"> <ul id="theFeature"> <li id="the1feature"><a href="#" name="#promo1"><img src="_images/carousel/promo1.jpg" /></a></li> <li id="the2feature"><a href="#" name="#promo2"><img src="_images/carousel/promo2.jpg" /></a></li> <li id="the3feature"><a href="#" name="#promo3"><img src="_images/carousel/promo3.jpg" /></a></li> </ul> <div id="promonav-con"> <div id="primarypromonav"> <ul class="links"> <li id="the1title" class="promotop"><a rel="1" href="#promo1" class="promo1" id="promo1" onMouseDown="promo1on()"><strong>Botox Cosmetic</strong></a></li> <li id="the2title" class="promotop"><a rel="2" href="#promo2" class="promo2" id="promo2" onMouseDown="promo2on()"><strong>Promo 2</strong></a></li> <li id="the3title" class="promotop"><a rel="3" href="#promo3" class="promo3" id="promo3" onMouseDown="promo3on()"><strong>Promo 3</strong></a></li> </ul> </div> </div> And here is the jquery.innerfade.js, with my changes: (function($) { $.fn.innerfade = function(options) { return this.each(function() { $.innerfade(this, options); }); }; $.innerfade = function(container, options) { var settings = { 'speed': 'normal', 'timeout': 2000, 'containerheight': 'auto', 'runningclass': 'innerfade', 'children': null }; if (options) $.extend(settings, options); if (settings.children === null) var elements = $(container).children(); else var elements = $(container).children(settings.children); if (elements.length > 1) { $(container).css('position', 'relative').css('height', settings.containerheight).addClass(settings.runningclass); for (var i = 0; i < elements.length; i++) { $(elements[i]).css('z-index', String(elements.length-i)).css('position', 'absolute').hide(); }; this.ifchanger = setTimeout(function() { $.innerfade.next(elements, settings, 1, 0); }, settings.timeout); $(elements[0]).show(); } }; $.innerfade.next = function(elements, settings, current, last) { $(elements[last]).fadeOut(settings.speed); $(elements[current]).fadeIn(settings.speed, function() { removeFilter($(this)[0]); }); if ((current + 1) < elements.length) { current = current + 1; last = current - 1; } else { current = 0; last = elements.length - 1; } this.ifchanger = setTimeout((function() { $.innerfade.next(elements, settings, current, last); }), settings.timeout); }; })(jQuery); // **** remove Opacity-Filter in ie **** function removeFilter(element) { if(element.style.removeAttribute){ element.style.removeAttribute('filter'); } } jQuery(document).ready(function() { jQuery('ul#theFeature').innerfade({ speed: 1000, timeout: 7000, containerheight: '291px' }); // jQuery('#mainFeature .links').children('li').children('a').attr('href', 'javascript:void(0);'); jQuery('#mainFeature .links').children('li').children('a').click(function() { clearTimeout(jQuery.innerfade.ifchanger); for(i=1;i<5;i++) { jQuery('#the'+i+'feature').css("display", "none"); //jQuery('#the'+i+'title').children('a').css("background-color","#226478"); } // if(the_widths[(jQuery(this).attr('rel')-1)]==960) { // jQuery("#vic").hide(); // } else { // jQuery("#vic").show(); // } // jQuery('#the'+(jQuery(this).attr('rel'))+'title').css("background-color", "#286a7f"); jQuery('#the'+(jQuery(this).attr('rel'))+'feature').css("display", "block"); clearTimeout(jQuery.innerfade.ifchanger); }); }); And the separate JavaScript that I created: function promo1on() {document.getElementById("promo1").className="promo1on"; document.getElementById("promo2").className="promo2"; document.getElementById("promo2").className="promo2"; } function promo2on() {document.getElementById("promo2").className="promo2on"; document.getElementById("promo1").className="promo1"; document.getElementById("promo3").className="promo3"; } function promo3on() {document.getElementById("promo3").className="promo3on"; document.getElementById("promo1").className="promo1"; document.getElementById("promo2").className="promo2"; } And, finally, the CSS: #mainFeature {float: left; width: 672px; height: 290px; margin: 0 0 9px 0; list-style: none;} #mainFeature li {list-style: none;} #mainFeature #theFeature {margin: 0; padding: 0; position: relative;} #mainFeature #theFeature li {position: absolute;

margin: 0; list-style: none; position: relative; font-family: arial, verdana, sans-serif; width: 463px; height: 26px;} #mainFeature .links li.promotop {list-style: none; display: block; float: left; display: inline; margin: 0; padding: 0;} #mainFeature .links li a {display: block; float: left; display: inline; height: 26px; text-decoration: none; margin: 0; padding: 0; cursor: pointer;} #mainFeature .links li a strong {margin-left: -9999px;} #mainFeature .links li a.promo1 {background: url(../_images/carouselnav/promo1.gif); width: 155px;} #mainFeature .links li:hover a.promo1 {background: url(../_images/carouselnav/promo1_hover.gif); width: 155px;} #mainFeature .links li a.promo1:hover {background: url(../_images/carouselnav/promo1_hover.gif); width: 155px;} .promo1on {background: url(../_images/carouselnav/promo1_on.gif); width: 155px;} #mainFeature .links li a.promo2 {background: url(../_images/carouselnav/promo2.gif); width: 153px;} #mainFeature .links li:hover a.promo2 {background: url(../_images/carouselnav/promo2_hover.gif); width: 153px;} #mainFeature .links li a.promo2:hover {background: url(../_images/carouselnav/promo2_hover.gif); width: 153px;} .promo2on {background: url(../_images/carouselnav/promo2_on.gif); width: 153px;} #mainFeature .links li a.promo3 {background: url(../_images/carouselnav/promo3.gif); width: 155px;} #mainFeature .links li:hover a.promo3 {background: url(../_images/carouselnav/promo3_hover.gif); width: 155px;} #mainFeature .links li a.promo3:hover {background: url(../_images/carouselnav/promo3_hover.gif); width: 155px;} .promo3on {background: url(../_images/carouselnav/promo3_on.gif); width: 155px;} Hopefully this makes sense! Again, I'm very new to JavaScript/JQuery, so I apologize if this is a mess. I'm very grateful for any suggestions. Thanks!

• Why doesn't this code work correctly?

  - by MisterSir

  I'm working on a website that displays galleries, using jCarousel. But no matter what I try, I can't get it to work, and I need to finish this by today. I have a very urgent schedule. My code basically takes image URLs from a database and sends them to AJAX, which passes it to jCarousel which makes the gallery. But there are a few problems: It doesn't display correctly! I can only get the last item pulled from the database, and it displays on the bottom-most row. After the item pulled from the database is displayed, the first time I click on "prev" there's no scroll effect, and the item just disappears! Only if I click on "next" 2-3 times there's a scroll effect and the item remains visible. My items are always displayed at the end of the carousel! This is urgent.. Please help me fix this. about.html: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-us"> <head> <script type="text/javascript" src="jquery-1.4.4.min.js"></script> <script type="text/javascript" src="/lib/jquery.jcarousel.min.js"></script> <link rel="stylesheet" type="text/css" href="/skins/tango/skin.css" /> <!--<style type="text/css"> #wrapper { width: 700px; margin-left: auto; margin-right: auto; } #carousel { margin-top: 120px; padding-left: 120px; } #side { padding-left: 550px; position: absolute; padding-top: 120px; } #hidden { color: #FFFFFF; } </style>--> <script type="text/javascript"> jQuery.easing['BounceEaseOut'] = function(p, t, b, c, d) { if ((t/=d) < (1/2.75)) { return c*(7.5625*t*t) + b; } else if (t < (2/2.75)) { return c*(7.5625*(t-=(1.5/2.75))*t + .75) + b; } else if (t < (2.5/2.75)) { return c*(7.5625*(t-=(2.25/2.75))*t + .9375) + b; } else { return c*(7.5625*(t-=(2.625/2.75))*t + .984375) + b; } }; function mycarousel_initCallback(carousel) { jQuery('#mycarousel-next').bind('click', function() { carousel.next(); return false; }); jQuery('#mycarousel-prev').bind('click', function() { carousel.prev(); return false; }); }; jQuery(document).ready(function() { jQuery('#mycarousel').jcarousel({ easing: 'BounceEaseOut', wrap: "first", initCallback: mycarousel_initCallback, animation: 1000, scroll: 3, visible: 3, buttonNextHTML: null, buttonPrevHTML: null }); jQuery('#mycarousel2').jcarousel({ easing: 'BounceEaseOut', animation: 1000, wrap: "first", initCallback: mycarousel_initCallback, scroll: 3, visible: 3, buttonNextHTML: null, buttonPrevHTML: null }); jQuery('#mycarousel3').jcarousel({ easing: 'BounceEaseOut', animation: 1000, scroll: 3, wrap: "first", initCallback: mycarousel_initCallback, visible: 3, buttonNextHTML: null, buttonPrevHTML: null }); }); var prevButton = null; function getObject(b, el) { var currbutton = b; var http; var url = "about.php"; var parameters = "d=carousel&cat=" + currbutton; try { http = new XMLHttpRequest(); } catch(e) { try { http = new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { http = new ActiveXObject("Microsoft.XMLHTTP"); } } function getServer() { if (http.readyState == 4) { var i = 0; var liArr = http.responseText; var built = liArr.split(", "); var li = document.createElement("li"); var ul1 = document.getElementById("mycarousel"); var ul2 = document.getElementById("mycarousel2"); var ul3 = document.getElementById("mycarousel3"); if (el != prevButton) { prevButton = el; while (ul1.hasChildNodes() ) {ul1.removeChild(ul1.lastChild);} while (ul2.hasChildNodes() ) {ul2.removeChild(ul2.lastChild);} while (ul3.hasChildNodes() ) {ul3.removeChild(ul3.lastChild);} } else return 0; while (i < (built.length) / 3) { li.innerHTML = built[i]; ul1.appendChild(li); i++; } while (i < ((built.length) / 3)*2) { li.innerHTML = built[i]; ul2.appendChild(li); i++; } while (i < (built.length)) { li.innerHTML = built[i]; ul3.appendChild(li); i++; } } } http.open("POST", url, true); http.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http.setRequestHeader("Content-length", parameters.length); http.setRequestHeader("Connection", "close"); http.onreadystatechange = getServer; http.send(parameters); } </script> </head> <body> <span id="hidden"> </span> <div id="wrapper"> <div id="side"> <form name="cats"> <input type="button" value="Hats" onclick="getObject('hats', this);"/><br /> <input type="button" value="Pants" onclick="getObject('pants', this);"/><br /> <input type="button" value="Shirts" onclick="getObject('shirts', this);"/><br /> </form> </div> <div id="carousel"> <ul id="mycarousel" class="jcarousel-skin-tango"> </ul> <ul id="mycarousel2" class="jcarousel-skin-tango"> </ul> <ul id="mycarousel3" class="jcarousel-skin-tango"> </ul> <input type="button" id="mycarousel-prev" value="prev" /> <input type="button" id="mycarousel-next" value="next" /> </div> </div> </body> </html> I commented the CSS because I thought it was giving me trouble, but honestly I have no idea what the hell's going on with jCarousel. about.php: <?php echo "<img width='75' height='75' src='http://static.flickr.com/66/199481236_dc98b5abb3_s.jpg' />, hi, hi, hi, hi, hi, hi, hi, hi"; ?> Also, even if there are no other items than what is displayed, I'm still able to scroll back, but not forward, assumingly because my item is always placed at the end of the carousel. I know it looks like a lot of code but it's really not! My formatting takes a lot of lines, the commented CSS takes a lot, and a lot of the code is HTML and jCarousel configuration, and there's also the BounceEasing effect which takes a few lines. There's not much actual code! So as I said, this is urgent and I need this fixed. But I can't get it to work. Please help me! Thanks for your time! EDIT: I changed the code a bit, but it still does not work. I really need help on this one!! EDIT: I added document.createElement("li"); to each while loop. Now all my items are displayed, but they are displayed vertically and not horizontally on each row. Other than that all other problems are the same. EDIT: Oh and also, in the row my image displays, only the image is there. Maybe jCarousel doesn't accept img and text, I don't know.
