  • GZip/Deflate Compression in ASP.NET MVC

    - by Rick Strahl
    A long while back I wrote about GZip compression in ASP.NET. In that article I describe two generic helper methods that I've used in all sorts of ASP.NET application from WebForms apps to HttpModules and HttpHandlers that require gzip or deflate compression. The same static methods also work in ASP.NET MVC. Here are the two routines:/// <summary> /// Determines if GZip is supported /// </summary> /// <returns></returns> public static bool IsGZipSupported() { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(AcceptEncoding) && (AcceptEncoding.Contains("gzip") || AcceptEncoding.Contains("deflate"))) return true; return false; } /// <summary> /// Sets up the current page or handler to use GZip through a Response.Filter /// IMPORTANT: /// You have to call this method before any output is generated! /// </summary> public static void GZipEncodePage() { HttpResponse Response = HttpContext.Current.Response; if (IsGZipSupported()) { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (AcceptEncoding.Contains("gzip")) { Response.Filter = new System.IO.Compression.GZipStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "gzip"); } else { Response.Filter = new System.IO.Compression.DeflateStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "deflate"); } } // Allow proxy servers to cache encoded and unencoded versions separately Response.AppendHeader("Vary", "Content-Encoding"); } The first method checks whether the client sending the request includes the accept-encoding for either gzip or deflate, and if if it does it returns true. The second function uses IsGzipSupported() to decide whether it should encode content and uses an Response Filter to do its job. Basically response filters look at the Response output stream as it's written and convert the data flowing through it. Filters are a bit tricky to work with but the two .NET filter streams for GZip and Deflate Compression make this a snap to implement. In my old code and even now in MVC I can always do:public ActionResult List(string keyword=null, int category=0) { WebUtils.GZipEncodePage(); …} to encode my content. And that works just fine. The proper way: Create an ActionFilterAttribute However in MVC this sort of thing is typically better handled by an ActionFilter which can be applied with an attribute. So to be all prim and proper I created an CompressContentAttribute ActionFilter that incorporates those two helper methods and which looks like this:/// <summary> /// Attribute that can be added to controller methods to force content /// to be GZip encoded if the client supports it /// </summary> public class CompressContentAttribute : ActionFilterAttribute { /// <summary> /// Override to compress the content that is generated by /// an action method. /// </summary> /// <param name="filterContext"></param> public override void OnActionExecuting(ActionExecutingContext filterContext) { GZipEncodePage(); } /// <summary> /// Determines if GZip is supported /// </summary> /// <returns></returns> public static bool IsGZipSupported() { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(AcceptEncoding) && (AcceptEncoding.Contains("gzip") || AcceptEncoding.Contains("deflate"))) return true; return false; } /// <summary> /// Sets up the current page or handler to use GZip through a Response.Filter /// IMPORTANT: /// You have to call this method before any output is generated! /// </summary> public static void GZipEncodePage() { HttpResponse Response = HttpContext.Current.Response; if (IsGZipSupported()) { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (AcceptEncoding.Contains("gzip")) { Response.Filter = new System.IO.Compression.GZipStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "gzip"); } else { Response.Filter = new System.IO.Compression.DeflateStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "deflate"); } } // Allow proxy servers to cache encoded and unencoded versions separately Response.AppendHeader("Vary", "Content-Encoding"); } } It's basically the same code wrapped into an ActionFilter attribute, which intercepts requests MVC requests to Controller methods and lets you hook up logic before and after the methods have executed. Here I want to override OnActionExecuting() which fires before the Controller action is fired. With the CompressContentAttribute created, it can now be applied to either the controller as a whole:[CompressContent] public class ClassifiedsController : ClassifiedsBaseController { … } or to one of the Action methods:[CompressContent] public ActionResult List(string keyword=null, int category=0) { … } The former applies compression to every action method, while the latter is selective and only applies it to the individual action method. Is the attribute better than the static utility function? Not really, but it is the standard MVC way to hook up 'filter' content and that's where others are likely to expect to set options like this. In fact,  you have a bit more control with the utility function because you can conditionally apply it in code, but this is actually much less likely in MVC applications than old WebForms apps since controller methods tend to be more focused. Compression Caveats Http compression is very cool and pretty easy to implement in ASP.NET but you have to be careful with it - especially if your content might get transformed or redirected inside of ASP.NET. A good example, is if an error occurs and a compression filter is applied. ASP.NET errors don't clear the filter, but clear the Response headers which results in some nasty garbage because the compressed content now no longer matches the headers. Another issue is Caching, which has to account for all possible ways of compression and non-compression that the content is served. Basically compressed content and caching don't mix well. I wrote about several of these issues in an old blog post and I recommend you take a quick peek before diving into making every bit of output Gzip encoded. None of these are show stoppers, but you have to be aware of the issues.

  • Component based game engine design

    - by a_m0d
    I have been looking at game engine design (specifically focused on 2d game engines, but also applicable to 3d games), and am interested in some information on how to go about it. I have heard that many engines are moving to a component based design nowadays rather than the traditional deep-object hierarchy. Do you know of any good links with information on how these sorts of designs are often implemented? I have seen evolve your hierarchy, but I can't really find many more with detailed information (most of them just seem to say "use components rather than a hierarchy" but I have found that it takes a bit of effort to switch my thinking between the two models). Any good links or information on this would be appreciated, and even books, although links and detailed answers here would be preferred.

  • Using Data Annotations on POCO's with MVC for Remote Validation

    - by Click Ahead
    Hi All, I am developing an ASP.NET MVC app and I've been looking into using Data Annotations on my POCO's which are defined in my Service Layer. As long as I have a reference to System.ComponentModel & System.ComponentModel.DataAnnotations this is no problem and what I like about this is that it allows me to reuse my Service Layer in a Win Forms app. I'm now looking to do some Remote Validation using Data Annotations and have taken a look at this article: http://msdn.microsoft.com/en-us/library/ff398048(VS.100).aspx However, to use the Data Annotations in this context I need to reference System.Web.MVC, System.Web and System.Web.Routing. This introduces a dependency on the Web DLL's, which limits me somewhat. Can anyone recommend a good clean way to implement Remote Data Validation using Data Annotations that isn't coupled with ASP.NET MVC or maybe suggest a better alternative. Thanks for the help !

  • SQL SERVER – Guest Post – Jonathan Kehayias – Wait Type – Day 16 of 28

    - by pinaldave
    Jonathan Kehayias (Blog | Twitter) is a MCITP Database Administrator and Developer, who got started in SQL Server in 2004 as a database developer and report writer in the natural gas industry. After spending two and a half years working in TSQL, in late 2006, he transitioned to the role of SQL Database Administrator. His primary passion is performance tuning, where he frequently rewrites queries for better performance and performs in depth analysis of index implementation and usage. Jonathan blogs regularly on SQLBlog, and was a coauthor of Professional SQL Server 2008 Internals and Troubleshooting. On a personal note, I think Jonathan is extremely positive person. In every conversation with him I have found that he is always eager to help and encourage. Every time he finds something needs to be approved, he has contacted me without hesitation and guided me to improve, change and learn. During all the time, he has not lost his focus to help larger community. I am honored that he has accepted to provide his views on complex subject of Wait Types and Queues. Currently I am reading his series on Extended Events. Here is the guest blog post by Jonathan: SQL Server troubleshooting is all about correlating related pieces of information together to indentify where exactly the root cause of a problem lies. In my daily work as a DBA, I generally get phone calls like, “So and so application is slow, what’s wrong with the SQL Server.” One of the funny things about the letters DBA is that they go so well with Default Blame Acceptor, and I really wish that I knew exactly who the first person was that pointed that out to me, because it really fits at times. A lot of times when I get this call, the problem isn’t related to SQL Server at all, but every now and then in my initial quick checks, something pops up that makes me start looking at things further. The SQL Server is slow, we see a number of tasks waiting on ASYNC_IO_COMPLETION, IO_COMPLETION, or PAGEIOLATCH_* waits in sys.dm_exec_requests and sys.dm_exec_waiting_tasks. These are also some of the highest wait types in sys.dm_os_wait_stats for the server, so it would appear that we have a disk I/O bottleneck on the machine. A quick check of sys.dm_io_virtual_file_stats() and tempdb shows a high write stall rate, while our user databases show high read stall rates on the data files. A quick check of some performance counters and Page Life Expectancy on the server is bouncing up and down in the 50-150 range, the Free Page counter consistently hits zero, and the Free List Stalls/sec counter keeps jumping over 10, but Buffer Cache Hit Ratio is 98-99%. Where exactly is the problem? In this case, which happens to be based on a real scenario I faced a few years back, the problem may not be a disk bottleneck at all; it may very well be a memory pressure issue on the server. A quick check of the system spec’s and it is a dual duo core server with 8GB RAM running SQL Server 2005 SP1 x64 on Windows Server 2003 R2 x64. Max Server memory is configured at 6GB and we think that this should be enough to handle the workload; or is it? This is a unique scenario because there are a couple of things happening inside of this system, and they all relate to what the root cause of the performance problem is on the system. If we were to query sys.dm_exec_query_stats for the TOP 10 queries, by max_physical_reads, max_logical_reads, and max_worker_time, we may be able to find some queries that were using excessive I/O and possibly CPU against the system in their worst single execution. We can also CROSS APPLY to sys.dm_exec_sql_text() and see the statement text, and also CROSS APPLY sys.dm_exec_query_plan() to get the execution plan stored in cache. Ok, quick check, the plans are pretty big, I see some large index seeks, that estimate 2.8GB of data movement between operators, but everything looks like it is optimized the best it can be. Nothing really stands out in the code, and the indexing looks correct, and I should have enough memory to handle this in cache, so it must be a disk I/O problem right? Not exactly! If we were to look at how much memory the plan cache is taking by querying sys.dm_os_memory_clerks for the CACHESTORE_SQLCP and CACHESTORE_OBJCP clerks we might be surprised at what we find. In SQL Server 2005 RTM and SP1, the plan cache was allowed to take up to 75% of the memory under 8GB. I’ll give you a second to go back and read that again. Yes, you read it correctly, it says 75% of the memory under 8GB, but you don’t have to take my word for it, you can validate this by reading Changes in Caching Behavior between SQL Server 2000, SQL Server 2005 RTM and SQL Server 2005 SP2. In this scenario the application uses an entirely adhoc workload against SQL Server and this leads to plan cache bloat, and up to 4.5GB of our 6GB of memory for SQL can be consumed by the plan cache in SQL Server 2005 SP1. This in turn reduces the size of the buffer cache to just 1.5GB, causing our 2.8GB of data movement in this expensive plan to cause complete flushing of the buffer cache, not just once initially, but then another time during the queries execution, resulting in excessive physical I/O from disk. Keep in mind that this is not the only query executing at the time this occurs. Remember the output of sys.dm_io_virtual_file_stats() showed high read stalls on the data files for our user databases versus higher write stalls for tempdb? The memory pressure is also forcing heavier use of tempdb to handle sorting and hashing in the environment as well. The real clue here is the Memory counters for the instance; Page Life Expectancy, Free List Pages, and Free List Stalls/sec. The fact that Page Life Expectancy is fluctuating between 50 and 150 constantly is a sign that the buffer cache is experiencing constant churn of data, once every minute to two and a half minutes. If you add to the Page Life Expectancy counter, the consistent bottoming out of Free List Pages along with Free List Stalls/sec consistently spiking over 10, and you have the perfect memory pressure scenario. All of sudden it may not be that our disk subsystem is the problem, but is instead an innocent bystander and victim. Side Note: The Page Life Expectancy counter dropping briefly and then returning to normal operating values intermittently is not necessarily a sign that the server is under memory pressure. The Books Online and a number of other references will tell you that this counter should remain on average above 300 which is the time in seconds a page will remain in cache before being flushed or aged out. This number, which equates to just five minutes, is incredibly low for modern systems and most published documents pre-date the predominance of 64 bit computing and easy availability to larger amounts of memory in SQL Servers. As food for thought, consider that my personal laptop has more memory in it than most SQL Servers did at the time those numbers were posted. I would argue that today, a system churning the buffer cache every five minutes is in need of some serious tuning or a hardware upgrade. Back to our problem and its investigation: There are two things really wrong with this server; first the plan cache is excessively consuming memory and bloated in size and we need to look at that and second we need to evaluate upgrading the memory to accommodate the workload being performed. In the case of the server I was working on there were a lot of single use plans found in sys.dm_exec_cached_plans (where usecounts=1). Single use plans waste space in the plan cache, especially when they are adhoc plans for statements that had concatenated filter criteria that is not likely to reoccur with any frequency.  SQL Server 2005 doesn’t natively have a way to evict a single plan from cache like SQL Server 2008 does, but MVP Kalen Delaney, showed a hack to evict a single plan by creating a plan guide for the statement and then dropping that plan guide in her blog post Geek City: Clearing a Single Plan from Cache. We could put that hack in place in a job to automate cleaning out all the single use plans periodically, minimizing the size of the plan cache, but a better solution would be to fix the application so that it uses proper parameterized calls to the database. You didn’t write the app, and you can’t change its design? Ok, well you could try to force parameterization to occur by creating and keeping plan guides in place, or we can try forcing parameterization at the database level by using ALTER DATABASE <dbname> SET PARAMETERIZATION FORCED and that might help. If neither of these help, we could periodically dump the plan cache for that database, as discussed as being a problem in Kalen’s blog post referenced above; not an ideal scenario. The other option is to increase the memory on the server to 16GB or 32GB, if the hardware allows it, which will increase the size of the plan cache as well as the buffer cache. In SQL Server 2005 SP1, on a system with 16GB of memory, if we set max server memory to 14GB the plan cache could use at most 9GB  [(8GB*.75)+(6GB*.5)=(6+3)=9GB], leaving 5GB for the buffer cache.  If we went to 32GB of memory and set max server memory to 28GB, the plan cache could use at most 16GB [(8*.75)+(20*.5)=(6+10)=16GB], leaving 12GB for the buffer cache. Thankfully we have SQL Server 2005 Service Pack 2, 3, and 4 these days which include the changes in plan cache sizing discussed in the Changes to Caching Behavior between SQL Server 2000, SQL Server 2005 RTM and SQL Server 2005 SP2 blog post. In real life, when I was troubleshooting this problem, I spent a week trying to chase down the cause of the disk I/O bottleneck with our Server Admin and SAN Admin, and there wasn’t much that could be done immediately there, so I finally asked if we could increase the memory on the server to 16GB, which did fix the problem. It wasn’t until I had this same problem occur on another system that I actually figured out how to really troubleshoot this down to the root cause.  I couldn’t believe the size of the plan cache on the server with 16GB of memory when I actually learned about this and went back to look at it. SQL Server is constantly telling a story to anyone that will listen. As the DBA, you have to sit back and listen to all that it’s telling you and then evaluate the big picture and how all the data you can gather from SQL about performance relate to each other. One of the greatest tools out there is actually a free in the form of Diagnostic Scripts for SQL Server 2005 and 2008, created by MVP Glenn Alan Berry. Glenn’s scripts collect a majority of the information that SQL has to offer for rapid troubleshooting of problems, and he includes a lot of notes about what the outputs of each individual query might be telling you. When I read Pinal’s blog post SQL SERVER – ASYNC_IO_COMPLETION – Wait Type – Day 11 of 28, I noticed that he referenced Checking Memory Related Performance Counters in his post, but there was no real explanation about why checking memory counters is so important when looking at an I/O related wait type. I thought I’d chat with him briefly on Google Talk/Twitter DM and point this out, and offer a couple of other points I noted, so that he could add the information to his blog post if he found it useful.  Instead he asked that I write a guest blog for this. I am honored to be a guest blogger, and to be able to share this kind of information with the community. The information contained in this blog post is a glimpse at how I do troubleshooting almost every day of the week in my own environment. SQL Server provides us with a lot of information about how it is running, and where it may be having problems, it is up to us to play detective and find out how all that information comes together to tell us what’s really the problem.

  • BSOD Before Windows Will Loads - Graphics Related

    - by Brian
    Alright deep breath here: (Windows 7 Home Premium 64 bit btw) Today I installed Star Craft 2 Beta. After trying to log in, it had some issues where it said my device stopped working (referring to my video device I have to imagine). After I force quit the game there were some random "hot" (various colors if i remember correctly) pixels on the screen. I decided to reboot and try again with similar results. I figured that maybe my display drivers could stand to be updated (I don't frequently update them as I don't often run into problems). I went out to nVidia's website and grabbed the latest drivers for Windows 7 64 bit GeForce 9 series. (I have SLi-ed 9800 GTs). Everything seemed to install fine and I performed the restart. This is when things went from bad (can't play SC2 beta ;) ) to worse (can't boot into windows!). Initially the very first splash screen - I think it's the bios splash screen - had lines of colored pixels covering it. It then displayed a screen that had lots of "(" on it. After that it showed the normal windows 7 splash screen as if it were going to load into Windows. Before getting much further, it BSODed on me. It was a 0x0000003B stop error. At nvlddmkm.sys. A little digging let verified that this was a problem with an nVidia graphics device, not a real shocker. Windows decided it would try to help me diagnose the problem, which it's only answer to was a System Restore, which did nothing to alleviate the problem. I was able to boot up fine in safe mode and was not able to roll back the driver, however I did uninstall the driver and reboot. I still had the graphical anomalies during the first two screens (same colored "."'s and weird "("'s), but there was NOT a stop error. Windows loaded up, found a default driver for the device and installed it and I restarted to let it load - and had yet another BSOD Stop error. Repeat driver uninstall, this time I reloaded the same version (I think it's possible that I was running a 32 bit version or a vista versus windows 7 version, but I don't have that information handy) of the nVidia driver from their website. Restart, same anomalies, same Stop Error. I am at a loss - At this point all I can think is that the firmware for the Video cards got fried or there's actual damage to the cards which I sincerely hope is not the case but the sooner I know the better. Any insight into what I might be able to do to troubleshoot/fix this problem would be most helpful. Attached below is a dump from DxDiag.

  • Refreshing Your PC Won’t Help: Why Bloatware is Still a Problem on Windows 8

    - by Chris Hoffman
    Bloatware is still a big problem on new Windows 8 and 8.1 PCs. Some websites will tell you that you can easily get rid of manufacturer-installed bloatware with Windows 8′s Reset feature, but they’re generally wrong. This junk software often turns the process of powering on your new PC from what could be a delightful experience into a tedious slog, forcing you to spend hours cleaning up your new PC before you can enjoy it. Why Refreshing Your PC (Probably) Won’t Help Manufacturers install software along with Windows on their new PCs. In addition to hardware drivers that allow the PC’s hardware to work properly, they install more questionable things like trial antivirus software and other nagware. Much of this software runs at boot, cluttering the system tray and slowing down boot times, often dramatically. Software companies pay computer manufacturers to include this stuff. It’s installed to make the PC manufacturer money at the cost of making the Windows computer worse for actual users. Windows 8 includes “Refresh Your PC” and “Reset Your PC” features that allow Windows users to quickly get their computers back to a fresh state. It’s essentially a quick, streamlined way of reinstalling Windows.  If you install Windows 8 or 8.1 yourself, the Refresh operation will give your PC a clean Windows system without any additional third-party software. However, Microsoft allows computer manufacturers to customize their Refresh images. In other words, most computer manufacturers will build their drivers, bloatware, and other system customizations into the Refresh image. When you Refresh your computer, you’ll just get back to the factory-provided system complete with bloatware. It’s possible that some computer manufacturers aren’t building bloatware into their refresh images in this way. It’s also possible that, when Windows 8 came out, some computer manufacturer didn’t realize they could do this and that refreshing a new PC would strip the bloatware. However, on most Windows 8 and 8.1 PCs, you’ll probably see bloatware come back when you refresh your PC. It’s easy to understand how PC manufacturers do this. You can create your own Refresh images on Windows 8 and 8.1 with just a simple command, replacing Microsoft’s image with a customized one. Manufacturers can install their own refresh images in the same way. Microsoft doesn’t lock down the Refresh feature. Desktop Bloatware is Still Around, Even on Tablets! Not only is typical Windows desktop bloatware not gone, it has tagged along with Windows as it moves to new form factors. Every Windows tablet currently on the market — aside from Microsoft’s own Surface and Surface 2 tablets — runs on a standard Intel x86 chip. This means that every Windows 8 and 8.1 tablet you see in stores has a full desktop with the capability to run desktop software. Even if that tablet doesn’t come with a keyboard, it’s likely that the manufacturer has preinstalled bloatware on the tablet’s desktop. Yes, that means that your Windows tablet will be slower to boot and have less memory because junk and nagging software will be on its desktop and in its system tray. Microsoft considers tablets to be PCs, and PC manufacturers love installing their bloatware. If you pick up a Windows tablet, don’t be surprised if you have to deal with desktop bloatware on it. Microsoft Surfaces and Signature PCs Microsoft is now selling their own Surface PCs that they built themselves — they’re now a “devices and services” company after all, not a software company. One of the nice things about Microsoft’s Surface PCs is that they’re free of the typical bloatware. Microsoft won’t take money from Norton to include nagging software that worsens the experience. If you pick up a Surface device that provides Windows 8.1 and 8 as Microsoft intended it — or install a fresh Windows 8.1 or 8 system — you won’t see any bloatware. Microsoft is also continuing their Signature program. New PCs purchased from Microsoft’s official stores are considered “Signature PCs” and don’t have the typical bloatware. For example, the same laptop could be full of bloatware in a traditional computer store and clean, without the nasty bloatware when purchased from a Microsoft Store. Microsoft will also continue to charge you $99 if you want them to remove your computer’s bloatware for you — that’s the more questionable part of the Signature program. Windows 8 App Bloatware is an Improvement There’s a new type of bloatware on new Windows 8 systems, which is thankfully less harmful. This is bloatware in the form of included “Windows 8-style”, “Store-style”, or “Modern” apps in the new, tiled interface. For example, Amazon may pay a computer manufacturer to include the Amazon Kindle app from the Windows Store. (The manufacturer may also just receive a cut of book sales for including it. We’re not sure how the revenue sharing works — but it’s clear PC manufacturers are getting money from Amazon.) The manufacturer will then install the Amazon Kindle app from the Windows Store by default. This included software is technically some amount of clutter, but it doesn’t cause the problems older types of bloatware does. It won’t automatically load and delay your computer’s startup process, clutter your system tray, or take up memory while you’re using your computer. For this reason, a shift to including new-style apps as bloatware is a definite improvement over older styles of bloatware. Unfortunately, this type of bloatware has not replaced traditional desktop bloatware, and new Windows PCs will generally have both. Windows RT is Immune to Typical Bloatware, But… Microsoft’s Windows RT can’t run Microsoft desktop software, so it’s immune to traditional bloatware. Just as you can’t install your own desktop programs on it, the Windows RT device’s manufacturer can’t install their own desktop bloatware. While Windows RT could be an antidote to bloatware, this advantage comes at the cost of being able to install any type of desktop software at all. Windows RT has also seemingly failed — while a variety of manufacturers came out with their own Windows RT devices when Windows 8 was first released, they’ve all since been withdrawn from the market. Manufacturers who created Windows RT devices have criticized it in the media and stated they have no plans to produce any future Windows RT devices. The only Windows RT devices still on the market are Microsoft’s Surface (originally named Surface RT) and Surface 2. Nokia is also coming out with their own Windows RT tablet, but they’re in the process of being purchased by Microsoft. In other words, Windows RT just isn’t a factor when it comes to bloatware — you wouldn’t get a Windows RT device unless you purchased a Surface, but those wouldn’t come with bloatware anyway. Removing Bloatware or Reinstalling Windows 8.1 While bloatware is still a problem on new Windows systems and the Refresh option probably won’t help you, you can still eliminate bloatware in the traditional way. Bloatware can be uninstalled from the Windows Control Panel or with a dedicated removal tool like PC Decrapifier, which tries to automatically uninstall the junk for you. You can also do what Windows geeks have always tended to do with new computers — reinstall Windows 8 or 8.1 from scratch with installation media from Microsoft. You’ll get a clean Windows system and you can install only the hardware drivers and other software you need. Unfortunately, bloatware is still a big problem for Windows PCs. Windows 8 tries to do some things to address bloatware, but it ultimately comes up short. Most Windows PCs sold in most stores to most people will still have the typical bloatware slowing down the boot process, wasting memory, and adding clutter.

  • MySQL InnoDB Corruption after power outage, possible to recover?

    - by Tim Hackett
    Hey Guys, I recently started trying to get Redmine up and running after a power outage that seems to have corrupted our InnoDB database in MySQL. Redmine had an extensive set of documentation that I would like to get even if redmine isn't able to run. The service fails on startup. I have tried inserting innodb_force_recovery = 4 per the documentation from the url in the error log. (also tried 1 thru 6 as I have backed up all directories after the corruption) I have verified through "mysqld-nt --print-defaults" that it is starting with the recovery option in the params. The machine is running Windows Server 2003 SP2, Xeon E5335 with 2GB RAM, MySQL is not mirrored to another machine, nor is the machine a mirror. I do not have any backups because the previous person did not set them up.

  • JavaScript Intellisense with Telerik in ASP.NET Master Page Project with VS 2010

    - by Otto Neff
    Today I was looking for a solution to get finally the JScript/Javascript/jQuery Intellisense Featureworking with my ASP.Net Webform Project to work. I found some good articles: - JScript IntelliSense Overview- JScript IntelliSense: A Reference for the “Reference” Tag- Enabling JavaScript intellisense in VS.NET 2010 to work with SharePoint 2010- Rich IntelliSense for jQueryBUT, all of suggested solutions did not work right with my Master Page based Visual Studio 2010 Solution.Only with physical Javascript Files (Telerik includes certain Javascript Files like jQuery as Ressource) or/andconfigure always a new ASP.NET Scriptmanager / RadScriptManager on every page derived from the Master Page, wasn't exactly what I was looking for. So I came up with the following simple Solution, to Trick VS2010and still have the Project running with multiple runat="server" Scriptmanagers. In short:- New ASP.NET control derived from ScriptManager with emtpy overwritten OnInit() to use it as emtpy wrapper for VS2010. In detail:New RadScriptManager Classusing System; using System.Collections.Generic; using System.Linq; using System.Web; using Telerik.Web.UI; namespace IntellisenseJavascript.Controls { public class IntelliJS : RadScriptManager { protected override void OnInit(EventArgs e) { } protected override void OnPreRender(EventArgs e) { } protected override void OnLoad(EventArgs e) { } protected override void Render(System.Web.UI.HtmlTextWriter writer) { } public override void RenderControl(System.Web.UI.HtmlTextWriter writer) { } } } web.config<configuration> ... <system.web> ... <pages> <controls> <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI, Version=2011.3.1115.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/> <add tagPrefix="VSFix" namespace="IntellisenseJavascript.Controls" assembly="IntellisenseJavascript"/> </controls> </pages> ...

  • Additional options in MDL

    - by Jane Zhang
        The Metadata Loader(MDL) enables you to populate a new repository as well as transfer, update, or restore a backup of existing repository metadata. It consists of two utilities: metadata export and metadata import. The export utility extracts metadata objects from a repository and writes the information into a file. The import utility reads the metadata information from an exported file and inserts the metadata objects into a repository.      While the Design Client provides an intuitive UI that helps you perform the most commonly used export and import tasks, OMBPlus scripting enables you to specify some additional options, and manage a control file that allows you to perform more specialized export and import tasks. Is it possible to utilize these options in MDL from Design Client? This article will tell you how to achieve it.      A property file named mdl.properties is used to configure the additional options. It stores options in name/value pairs. This file can be created and placed under the directory <owb installation path>/owb/bin/admin/. Below we will introduce the options that can be specified in the mdl.properties file. 1. DEFAULTDIRECTORY     When we open a Metadata Export/Import dialog in Design Client, a default directory is provided for MDL file and log file. For MDL Export, the default directory is <owb installation path>/owb/bin/. As for MDL Import, the default directory is <owb installation path>/owb/mdl/. It may not be the one you would want to use as a default. You can specify the option DEFAULTDIRECTORY in the mdl.properties file to set your own default directory for MDL Export/Import, for example, DEFAULTDIRECOTRY=/tmp/     In this example, the default directory is set to /tmp/. Be sure the value ends with a file separator since it represents a directory. In Windows, the file separator is “\”. In linux, the file separator is “/”. 2. MDLTRACEFILE     Sometimes we would like to trace the whole process of MDL Export/Import, and get detailed information about operations to help developers or supports troubleshooting. To turn on MDL trace, set the option MDLTRACEFILE in the mdl.properties file. MDLTRACEFILE=/tmp/mdl.trc    The right side of the equals sign is to specify the name of the file for MDL trace information to be written. If no path is specified, the file will be placed under directory <owb installation path>/owb/bin/admin/. However, the trace file may be large if the MDL file contains a large number of metadata objects, so please use this option sparingly. 3. CONTROLFILE       We can use a control file to specify how objects are imported or exported. We can set an option called CONTROLFILE in the mdl.properties file, so the control file can also be utilized in Design Client, for example, CONTROLFILE=/tmp/mdl_control_file.ctl     The control file stores options in name/value pairs. When using control file, be sure the file exists, otherwise an exception java.lang.Exception: CNV0002-0031(ERROR): Cannot find specified file will be thrown out during MDL Export/Import.      Next we will introduce some options specified in control file. ZIPFILEFORMAT     By default, MDL exports objects into a zip format file. This zip file has an .mdl extension and contains two files. For example, you export the repository metadata into a file called projects.mdl. When you unzip this MDL file, you obtain two files. The file projects.mdx contains the repository objects. The file mdlcatalog.xml contains internal information about the MDL XML file. Another choice is to combine these two files into one unzip text format file when doing MDL exporting.    In OMBPlus command related to MDL, there is an option called FILE_FORMAT which is used to specify the file format for the exported file. Its acceptable values are ZIP or TEXT. When the value TEXT is selected, the exported file is in text format, for example, OMBEXPORT MDL_FILE '/tmp/options_file_format_test.mdl' FILE_FORMAT TEXT FROM PROJECT 'MY_PROJECT'    How to achieve this via Design Client when doing an MDL exporting? Here we have another option called ZIPFILEFORMAT which has the same function as the FILE_FORMAT. The difference is the acceptable values for ZIPFILEFORMAT are Y or N. When the value is set to N, the exported file is in text format, otherwise it is in zip file format. LOGMESSAGELEVEL     Whenever you export or import repository metadata, MDL writes diagnostic and statistical information to a log file. Their are 3 types of status messages: Informational, Warning and Error. By default, the log file includes all types of message. Sometimes, user may only care about one type of messages, for example, they would like only error messages written to the log file. In order to achieve this, we can set an option called LOGMESSAGELEVEL in control file. The acceptable values for LOGMESSAGELEVEL are ALL, WARNING and ERROR. ALL: If the option LOGMESSAGELEVEL is set to ALL, all types of messages (Informational, Warning and Error) will be written into the log file. WARNING: If the option LOGMESSAGELEVEL is set to WARNING, only warning messages will be written into log file. ERROR: If the option LOGMESSAGELEVEL is set to ERROR, only error messages will be written into log file. UPDATEPROJECTATTRIBUTES, UPDATEMODULEATTRIBUTES      These two options are used to decide whether updating the attributes of projects/modules. The options work when projects/modules being imported already exist in repository and we use update metadata mode or replace metadata mode to do the MDL import. The acceptable values for these two options are Y or N. If the value is set to Y, the attributes of projects/modules will be updated, otherwise not.      Next, let’s give an example to see how these options take effect in MDL. 1. First of all, create the property file mdl.properties under the directory <owb installation path>/owb/bin/admin/. 2. Specify the options in the mdl.properties file, see the following screenshot. 3. Create the control file mdl_control_file.ctl under the directory /tmp/. Set the following options in control file. 4. Log into the OWB Design Client. 5. Create an Oracle module named ORA_MOD_1 under the project MY_PROJECT, then export the project MY_PROJECT into file my_project.mdl. 6. Check the trace file mdl.trc under the directory /tmp/. In this file, we can see very detail information for the above export task. 7. Check the exported MDL file. The file my_project.mdl is in text format. Opening the file, you can see the content of the file directly. It concats the file my_project.mdx and mdlcatalog.xml. 8. Modify the project MY_PROJECT and Oracle module ORA_MOD_1, add descriptions for them separately. Delete the location created in step 5. 9. Import the MDL file my_project.mdl. From the Metadata Import dialog, we can see the default directory for MDL file and log file has been changed to /tmp/. Here we use update metadata mode, match by names to do the importing. 10. After importing, check the description of the project MY_PROJECT, we can see the description is still there. But the description of the Oracle module ORA_MOD_1 has gone. That because we set the option UPDATEPROJECTATTRIBUTES to N, and set the option UPDATEMODULEATTRIBUTES to Y. 11. Check the log file, the log file only contains warning messages and the log message level is set to WARNING.      For more details about the 3 types of status messages, see Oracle® Warehouse Builder Installation and Administration Guide11g Release 2.

  • Making Sense of ASP.NET Paths

    - by Renso
    Making Sense of ASP.NET Paths ASP.Net includes quite a plethora of properties to retrieve path information about the current request, control and application. There's a ton of information available about paths on the Request object, some of it appearing to overlap and some of it buried several levels down, and it can be confusing to find just the right path that you are looking for. To keep things straight I thought it a good idea to summarize the path options along with descriptions and example paths. I wrote a post about this a long time ago in 2004 and I find myself frequently going back to that page to quickly figure out which path I’m looking for in processing the current URL. Apparently a lot of people must be doing the same, because the original post is the second most visited even to this date on this blog to the tune of nearly 500 hits per day. So, I decided to update and expand a bit on the original post with a little more information and clarification based on the original comments. Request Object Paths Available Here's a list of the Path related properties on the Request object (and the Page object). Assume a path like http://www.west-wind.com/webstore/admin/paths.aspx for the paths below where webstore is the name of the virtual. Request Property Description and Value ApplicationPath Returns the web root-relative logical path to the virtual root of this app. /webstore/ PhysicalApplicationPath Returns local file system path of the virtual root for this app. c:\inetpub\wwwroot\webstore PhysicalPath Returns the local file system path to the current script or path. c:\inetpub\wwwroot\webstore\admin\paths.aspx Path FilePath CurrentExecutionFilePath All of these return the full root relative logical path to the script page including path and scriptname. CurrentExcecutionFilePath will return the ‘current’ request path after a Transfer/Execute call while FilePath will always return the original request’s path. /webstore/admin/paths.aspx AppRelativeCurrentExecutionFilePath Returns an ASP.NET root relative virtual path to the script or path for the current request. If in  a Transfer/Execute call the transferred Path is returned. ~/admin/paths.aspx PathInfo Returns any extra path following the script name. If no extra path is provided returns the root-relative path (returns text in red below). string.Empty if no PathInfo is available. /webstore/admin/paths.aspx/ExtraPathInfo RawUrl Returns the full root relative URL including querystring and extra path as a string. /webstore/admin/paths.aspx?sku=wwhelp40 Url Returns a fully qualified URL including querystring and extra path. Note this is a Uri instance rather than string. http://www.west-wind.com/webstore/admin/paths.aspx?sku=wwhelp40 UrlReferrer The fully qualified URL of the page that sent the request. This is also a Uri instance and this value is null if the page was directly accessed by typing into the address bar or using an HttpClient based Referrer client Http header. http://www.west-wind.com/webstore/default.aspx?Info Control.TemplateSourceDirectory Returns the logical path to the folder of the page, master or user control on which it is called. This is useful if you need to know the path only to a Page or control from within the control. For non-file controls this returns the Page path. /webstore/admin/ As you can see there’s a ton of information available there for each of the three common path formats: Physical Path is an OS type path that points to a path or file on disk. Logical Path is a Web path that is relative to the Web server’s root. It includes the virtual plus the application relative path. ~/ (Root-relative) Path is an ASP.NET specific path that includes ~/ to indicate the virtual root Web path. ASP.NET can convert virtual paths into either logical paths using Control.ResolveUrl(), or physical paths using Server.MapPath(). Root relative paths are useful for specifying portable URLs that don’t rely on relative directory structures and very useful from within control or component code. You should be able to get any necessary format from ASP.NET from just about any path or script using these mechanisms. ~/ Root Relative Paths and ResolveUrl() and ResolveClientUrl() ASP.NET supports root-relative virtual path syntax in most of its URL properties in Web Forms. So you can easily specify a root relative path in a control rather than a location relative path: <asp:Image runat="server" ID="imgHelp" ImageUrl="~/images/help.gif" /> ASP.NET internally resolves this URL by using ResolveUrl("~/images/help.gif") to arrive at the root-relative URL of /webstore/images/help.gif which uses the Request.ApplicationPath as the basepath to replace the ~. By convention any custom Web controls also should use ResolveUrl() on URL properties to provide the same functionality. In your own code you can use Page.ResolveUrl() or Control.ResolveUrl() to accomplish the same thing: string imgPath = this.ResolveUrl("~/images/help.gif"); imgHelp.ImageUrl = imgPath; Unfortunately ResolveUrl() is limited to WebForm pages, so if you’re in an HttpHandler or Module it’s not available. ASP.NET Mvc also has it’s own more generic version of ResolveUrl in Url.Decode: <script src="<%= Url.Content("~/scripts/new.js") %>" type="text/javascript"></script> which is part of the UrlHelper class. In ASP.NET MVC the above sort of syntax is actually even more crucial than in WebForms due to the fact that views are not referencing specific pages but rather are often path based which can lead to various variations on how a particular view is referenced. In a Module or Handler code Control.ResolveUrl() unfortunately is not available which in retrospect seems like an odd design choice – URL resolution really should happen on a Request basis not as part of the Page framework. Luckily you can also rely on the static VirtualPathUtility class: string path = VirtualPathUtility.ToAbsolute("~/admin/paths.aspx"); VirtualPathUtility also many other quite useful methods for dealing with paths and converting between the various kinds of paths supported. One thing to watch out for is that ToAbsolute() will throw an exception if a query string is provided and doesn’t work on fully qualified URLs. I wrote about this topic with a custom solution that works fully qualified URLs and query strings here (check comments for some interesting discussions too). Similar to ResolveUrl() is ResolveClientUrl() which creates a fully qualified HTTP path that includes the protocol and domain name. It’s rare that this full resolution is needed but can be useful in some scenarios. Mapping Virtual Paths to Physical Paths with Server.MapPath() If you need to map root relative or current folder relative URLs to physical URLs or you can use HttpContext.Current.Server.MapPath(). Inside of a Page you can do the following: string physicalPath = Server.MapPath("~/scripts/ww.jquery.js")); MapPath is pretty flexible and it understands both ASP.NET style virtual paths as well as plain relative paths, so the following also works. string physicalPath = Server.MapPath("scripts/silverlight.js"); as well as dot relative syntax: string physicalPath = Server.MapPath("../scripts/jquery.js"); Once you have the physical path you can perform standard System.IO Path and File operations on the file. Remember with physical paths and IO or copy operations you need to make sure you have permissions to access files and folders based on the Web server user account that is active (NETWORK SERVICE, ASPNET typically). Note the Server.MapPath will not map up beyond the virtual root of the application for security reasons. Server and Host Information Between these settings you can get all the information you may need to figure out where you are at and to build new Url if necessary. If you need to build a URL completely from scratch you can get access to information about the server you are accessing: Server Variable Function and Example SERVER_NAME The of the domain or IP Address wwww.west-wind.com or 127.0.0.1 SERVER_PORT The port that the request runs under. 80 SERVER_PORT_SECURE Determines whether https: was used. 0 or 1 APPL_MD_PATH ADSI DirectoryServices path to the virtual root directory. Note that LM typically doesn’t work for ADSI access so you should replace that with LOCALHOST or the machine’s NetBios name. /LM/W3SVC/1/ROOT/webstore Request.Url and Uri Parsing If you still need more control over the current request URL or  you need to create new URLs from an existing one, the current Request.Url Uri property offers a lot of control. Using the Uri class and UriBuilder makes it easy to retrieve parts of a URL and create new URLs based on existing URL. The UriBuilder class is the preferred way to create URLs – much preferable over creating URIs via string concatenation. Uri Property Function Scheme The URL scheme or protocol prefix. http or https Port The port if specifically specified. DnsSafeHost The domain name or local host NetBios machine name www.west-wind.com or rasnote LocalPath The full path of the URL including script name and extra PathInfo. /webstore/admin/paths.aspx Query The query string if any ?id=1 The Uri class itself is great for retrieving Uri parts, but most of the properties are read only if you need to modify a URL in order to change it you can use the UriBuilder class to load up an existing URL and modify it to create a new one. Here are a few common operations I’ve needed to do to get specific URLs: Convert the Request URL to an SSL/HTTPS link For example to take the current request URL and converted  it to a secure URL can be done like this: UriBuilder build = new UriBuilder(Request.Url); build.Scheme = "https"; build.Port = -1; // don't inject portUri newUri = build.Uri; string newUrl = build.ToString(); Retrieve the fully qualified URL without a QueryString AFAIK, there’s no native routine to retrieve the current request URL without the query string. It’s easy to do with UriBuilder however: UriBuilder builder = newUriBuilder(Request.Url); builder.Query = ""; stringlogicalPathWithoutQuery = builder.ToString();

  • Application development using google applications?

    - by Ali
    Hi guys I'm developing a collaboration system and our team has been at it for the past couple of years. However the boss suggested that we try and redevelop it using something robust. Basically our collaboration system incorporates a webmail client and a custom built contacts management system plus project management system. My boss likes the robustness of GMAIL and Google docs and really would like a solution that if possible could incorporate these two and other google applications - I'm not so sure how to get started on developing a custom application using google applications - especially consider the fact that in the long run we wish to host our collaboration system as a paid service - just like the services that 37signals basecamp and highrise have been.

  • Recommendations on resolving a cs1705 error

    - by Scott A. Lawrence
    I'm upgrading a number of solutions from Visual Studio 2008 to Visual Studio 2010RC. In the process of doing this, I've encountered two instances of compiler error cs1705, one for System.Core and another for System.Data.Linq. In each case, an assembly compiled earlier has a reference to the .NET 4.0 version of these system assemblies, while the web project I'm trying to compile only has references to the .NET 3.5 version of them. Adding .NET 4.0 versions of System.Core and System.Data.Linq to the web project doesn't resolve the error. Removing the .NET 3.5 versions of the assemblies so that only the .NET 4.0 versions remain results in even more errors. Any recommendations on how to resolve this error would be greatly appreciated.

  • HR According to Batman

    - by D'Arcy Lussier
    Any idea who that guy is running alongside the Caped Crusader? That’s Nightwing, but you may know him as Robin…well, the first Robin anyway. There were actually like 5 Robin’s according to Wikipedia: Dick Grayson, the original, who’s parents were circus performers killed by a gangster. Jason Todd, who was caught trying to steal tires off of the Batmobile. Tim Drake, who saw Dick’s parents die and figured out who Batman and Robin were. and a few others that get into recent time travel/altered reality storylines. What does this have to do with HR? Well, it somewhat ties in with an article by Alex Papadimoulis from 2008. In the article he talks about the “Cravath System”. The Craveth system was developed by a law firm called Cravath, Swaine & Moore back in the 19th century. In a nutshell, they believed in hiring the best and brightest straight out of school. These aspiring lawyers would then begin a fight for survival in the firm, with the strong surviving. In what’s termed the “Up and Out” rule, employees needed to be promoted within 3 years or leave the company. They should achieve partner within 7 – 8 years and no later than 10 after initially coming on board (read all about the system on Wikipedia here). Back to Alex’s article, he quotes from a book published in 1947 about the lawfirm: Under the “Cravath system” of taking a substantial number of men annually and keeping a current constantly moving up in the office, and its philosophy of tenure, men are constantly leaving… it is often difficult to keep the best men long enough to determine whether they shall be made partners, for Cravath-trained men are always in demand, usually at premium salaries. And so we see a pattern forming here: 1. Hire a whole whack of smart college graduates 2. Put them to work 3. The ones that stick around should move up the ladder. The ones that don’t stick around served the company well and left to expound the quality of the Cravath firm. Those that didn’t fall into either of those categories were just let go. There’s some interesting undercurrents to these ideas. If you stick around, you better keep your feet moving! I was at a Microsoft shindig a few months back, and was talking to a Microsoft employee. He shared that at MS you have 5 years to achieve a “senior” position within the company. Once you hit that mark, you can stay there for the rest of your career (he told about a guy who’s a “senior” developer and has been for the last 20+ years working on audio drivers for Windows), but you *must* hit that mark within the timeframe. What we see with Microsoft is Cravath’s system in action, whether intentional or not: bring in smart young people and see which ones stick. You need to give people something to work towards. Saying “You must reach this level or else!” is one way to look at it. The other way is to see achieving a higher rank in the organization as something for ambitious employees to reach towards. It’s important for an organization to always have the next generation of executives waiting in the wings, and unless you’re encouraging that early on you may find yourself in a position of needing to fill positions that nobody has been working towards. Now, you might suggest that this isn’t that big of a deal because you could just hire someone from outside the organization, but the Cravath system holds to the tenet of promoting internally; develop your own talent, since your business is the best place for the future leadership to learn teh business from. It’s OK for people to quit. Alex’s article really drives this point home, but its worth noting here also: its OK for your people to quit. In fact its inevitable…and more inevitable that it’ll be good people that leave. Some will stay and work towards the internal awards of promotion, but a number will get experience, serve the organization well, and then move on to something else. This should be expected and treated as a natural business occurrence. The idea of an alumni of an organization begins to come into play here: “That guy used to work for <insert company here>”. There’s a benefit in that: those best and brightest will be drawn to your organization and your reputation will permeate your market through former staff that are sought after because of how well you nurtured them. The Batman Hook All of this brings us back to Batman and his HR practice: when Dick decided he’d had enough of the Robin schtick, he quit and became his own…but he was always associated with Batman and people understood where his training had come from. To the Dark Knight’s credit, he continued training partners under the Robin brand. Luckily he didn’t have to worry about firing any of them (the ship sort of sails when you reveal a secret identity), although there was that unfortunate “quitting” of the second Robin when the Joker blew him up…but regardless, we see the Cravath system at work: bring in talent, expect great things, and be ok with whatever they decide for their careers. It’s an interesting way to approach HR, and luckily for us our business isn’t as dangerous or over-the-top as the caped crusader’s.

  • How to access WebMethods in ASP.NET

    - by Quandary
    When i define an AJAX WebMethod like this in an ASPX page (ui.aspx): [System.Web.Services.WebMethod(Description = "Get Import Progress-Report")] [System.Web.Script.Services.ScriptMethod(UseHttpGet = false, ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)] public static string GetProgress() { System.Web.Script.Serialization.JavaScriptSerializer JSONserializer = new System.Web.Script.Serialization.JavaScriptSerializer(); return JSONserializer.Serialize("an Object/Instance here"); } // End WebMethod-Function GetProgress Can I access the description for the corresponding service somewhere ? E.g. when I want to call the webmethod with my own JavaScript, how do I do that ? I investigated the axd files, and found the xmlhttprequest to open ui.aspx/GetProgress But when I type the address in my browser, I get redirected to ui.aspx

  • C#/.NET Little Wonders: The EventHandler and EventHandler&lt;TEventArgs&gt; delegates

    - by James Michael Hare
    Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. In the last two weeks, we examined the Action family of delegates (and delegates in general), and the Func family of delegates and how they can be used to support generic, reusable algorithms and classes. So this week, we are going to look at a handy pair of delegates that can be used to eliminate the need for defining custom delegates when creating events: the EventHandler and EventHandler<TEventArgs> delegates. Events and delegates Before we begin, let’s quickly consider events in .NET.  According to the MSDN: An event in C# is a way for a class to provide notifications to clients of that class when some interesting thing happens to an object. So, basically, you can create an event in a type so that users of that type can subscribe to notifications of things of interest.  How is this different than some of the delegate programming that we talked about in the last two weeks?  Well, you can think of an event as a special access modifier on a delegate.  Some differences between the two are: Events are a special access case of delegates They behave much like delegates instances inside the type they are declared in, but outside of that type they can only be (un)subscribed to. Events can specify add/remove behavior explicitly If you want to do additional work when someone subscribes or unsubscribes to an event, you can specify the add and remove actions explicitly. Events have access modifiers, but these only specify the access level of those who can (un)subscribe A public event, for example, means anyone can (un)subscribe, but it does not mean that anyone can raise (invoke) the event directly.  Events can only be raised by the type that contains them In contrast, if a delegate is visible, it can be invoked outside of the object (not even in a sub-class!). Events tend to be for notifications only, and should be treated as optional Semantically speaking, events typically don’t perform work on the the class directly, but tend to just notify subscribers when something of note occurs. My basic rule-of-thumb is that if you are just wanting to notify any listeners (who may or may not care) that something has happened, use an event.  However, if you want the caller to provide some function to perform to direct the class about how it should perform work, make it a delegate. Declaring events using custom delegates To declare an event in a type, we simply use the event keyword and specify its delegate type.  For example, let’s say you wanted to create a new TimeOfDayTimer that triggers at a given time of the day (as opposed to on an interval).  We could write something like this: 1: public delegate void TimeOfDayHandler(object source, ElapsedEventArgs e); 2:  3: // A timer that will fire at time of day each day. 4: public class TimeOfDayTimer : IDisposable 5: { 6: // Event that is triggered at time of day. 7: public event TimeOfDayHandler Elapsed; 8:  9: // ... 10: } The first thing to note is that the event is a delegate type, which tells us what types of methods may subscribe to it.  The second thing to note is the signature of the event handler delegate, according to the MSDN: The standard signature of an event handler delegate defines a method that does not return a value, whose first parameter is of type Object and refers to the instance that raises the event, and whose second parameter is derived from type EventArgs and holds the event data. If the event does not generate event data, the second parameter is simply an instance of EventArgs. Otherwise, the second parameter is a custom type derived from EventArgs and supplies any fields or properties needed to hold the event data. So, in a nutshell, the event handler delegates should return void and take two parameters: An object reference to the object that raised the event. An EventArgs (or a subclass of EventArgs) reference to event specific information. Even if your event has no additional information to provide, you are still expected to provide an EventArgs instance.  In this case, feel free to pass the EventArgs.Empty singleton instead of creating new instances of EventArgs (to avoid generating unneeded memory garbage). The EventHandler delegate Because many events have no additional information to pass, and thus do not require custom EventArgs, the signature of the delegates for subscribing to these events is typically: 1: // always takes an object and an EventArgs reference 2: public delegate void EventHandler(object sender, EventArgs e) It would be insane to recreate this delegate for every class that had a basic event with no additional event data, so there already exists a delegate for you called EventHandler that has this very definition!  Feel free to use it to define any events which supply no additional event information: 1: public class Cache 2: { 3: // event that is raised whenever the cache performs a cleanup 4: public event EventHandler OnCleanup; 5:  6: // ... 7: } This will handle any event with the standard EventArgs (no additional information).  But what of events that do need to supply additional information?  Does that mean we’re out of luck for subclasses of EventArgs?  That’s where the generic for of EventHandler comes into play… The generic EventHandler<TEventArgs> delegate Starting with the introduction of generics in .NET 2.0, we have a generic delegate called EventHandler<TEventArgs>.  Its signature is as follows: 1: public delegate void EventHandler<TEventArgs>(object sender, TEventArgs e) 2: where TEventArgs : EventArgs This is similar to EventHandler except it has been made generic to support the more general case.  Thus, it will work for any delegate where the first argument is an object (the sender) and the second argument is a class derived from EventArgs (the event data). For example, let’s say we wanted to create a message receiver, and we wanted it to have a few events such as OnConnected that will tell us when a connection is established (probably with no additional information) and OnMessageReceived that will tell us when a new message arrives (probably with a string for the new message text). So for OnMessageReceived, our MessageReceivedEventArgs might look like this: 1: public sealed class MessageReceivedEventArgs : EventArgs 2: { 3: public string Message { get; set; } 4: } And since OnConnected needs no event argument type defined, our class might look something like this: 1: public class MessageReceiver 2: { 3: // event that is called when the receiver connects with sender 4: public event EventHandler OnConnected; 5:  6: // event that is called when a new message is received. 7: public event EventHandler<MessageReceivedEventArgs> OnMessageReceived; 8:  9: // ... 10: } Notice, nowhere did we have to define a delegate to fit our event definition, the EventHandler and generic EventHandler<TEventArgs> delegates fit almost anything we’d need to do with events. Sidebar: Thread-safety and raising an event When the time comes to raise an event, we should always check to make sure there are subscribers, and then only raise the event if anyone is subscribed.  This is important because if no one is subscribed to the event, then the instance will be null and we will get a NullReferenceException if we attempt to raise the event. 1: // This protects against NullReferenceException... or does it? 2: if (OnMessageReceived != null) 3: { 4: OnMessageReceived(this, new MessageReceivedEventArgs(aMessage)); 5: } The above code seems to handle the null reference if no one is subscribed, but there’s a problem if this is being used in multi-threaded environments.  For example, assume we have thread A which is about to raise the event, and it checks and clears the null check and is about to raise the event.  However, before it can do that thread B unsubscribes to the event, which sets the delegate to null.  Now, when thread A attempts to raise the event, this causes the NullReferenceException that we were hoping to avoid! To counter this, the simplest best-practice method is to copy the event (just a multicast delegate) to a temporary local variable just before we raise it.  Since we are inside the class where this event is being raised, we can copy it to a local variable like this, and it will protect us from multi-threading since multicast delegates are immutable and assignments are atomic: 1: // always make copy of the event multi-cast delegate before checking 2: // for null to avoid race-condition between the null-check and raising it. 3: var handler = OnMessageReceived; 4: 5: if (handler != null) 6: { 7: handler(this, new MessageReceivedEventArgs(aMessage)); 8: } The very slight trade-off is that it’s possible a class may get an event after it unsubscribes in a multi-threaded environment, but this is a small risk and classes should be prepared for this possibility anyway.  For a more detailed discussion on this, check out this excellent Eric Lippert blog post on Events and Races. Summary Generic delegates give us a lot of power to make generic algorithms and classes, and the EventHandler delegate family gives us the flexibility to create events easily, without needing to redefine delegates over and over.  Use them whenever you need to define events with or without specialized EventArgs.   Tweet Technorati Tags: .NET, C#, CSharp, Little Wonders, Generics, Delegates, EventHandler

  • Jenkins—get "Build Time Trend" values using "Remote Access API"

    - by Chathura Kulasinghe
    Is there a way that we can get all Jenkins-"Build Time Trend" information ( Build number + Status[success/failed etc] + Duration ) for an application; using the Jenkins remote access API? Or else I would appreciate if you could post a link of any documentation on how to get information from Jenkins using the Remote Access API. Most of the sources consist of the way of running jobs, but I couldn't find any, which shows how to fetch information from jenkins. Thanks!

  • How to configure MessageEndpointMapping by namespace in NServiceBus

    - by SteveBering
    I am trying to configure my message endpoint mapping in my NServiceBus configuration by sending messages from different namespaces to different endpoints. As such, I have configured the following in my web.config: However, when my application starts, I receive the following exception: Spring.Objects.PropertyAccessExceptionsException: PropertyAccessExceptionsException (1 errors); nested PropertyAccessExceptions are: [Spring.Core.TypeMismatchException: Cannot convert property value of type [System.Collections.Hashtable] to required type [System.Collections.IDictionary] for property 'MessageOwners'., Inner Exception: System.ArgumentException: Problem loading message assembly: Company.Messages.Payments --- System.IO.FileNotFoundException: Could not load file or assembly 'Company.Messages.Payments' or one of its dependencies. The system cannot find the file specified. File name: 'Company.Messages.Payments' What I find interesting is that it seems to have found Company.Messages.Accounts but failed on the second configured line. I thought that maybe it didn't like have them all go to the same endpoint, but changing this configuration to have them go different endpoints didn't change the error message I received. What am I doing wrong? Is it not possible to segment messages by namespace (all I have seen is by type and by assembly)? Thanks, Steve

  • Silverlight Project - Setting Reference to Copy Local false not working.

    - by cmaduro
    Why is it that when my Silverlight project is built, the output directory contains a bunch of culture specific directories: ar\System.Windows.Controls.resources.dll bg\System.Windows.Controls.resources.dll ca\System.Windows.Controls.resources.dll etc etc etc Also the root of the build output contains: System.Xml.Linq.dll System.windows.Controls.dll I have gone through the projects in my solution and made sure that "Copy Local" is set to false for all the referances of the mentioned dll files. Those 2 files were set to true, but I did switch them to false. Despite my effort to google an answer, I remain stuck.
