  • VB .Net LINQ query to determine whether more than one element has the same value for a property?

    - by Alex Hope O'Connor
    I am trying to write a LINQ query which will return true if there are multiple objects which have a property with the same value. Here is what I have come up with so far: Formatters.Where(Function(f As DataModel.Formatter) _ Formatters.Select(Function(f2 As DataModel.Formatter) f2.Name.ToLower()).Contains(f.Name.ToLower())).Count > 1 However the above always returns true as long as their are more then 1 elements in the list, can someone please give me a hand with this? Thanks, Alex.

  • Change storyboard UIImageView to own class with backgroundcolor

    - by Thomas
    I want to draw the background image on my own, so I decided to implement a UIImageView class and connect it in the Storyboard. As first task I just want to set the backgroundcolor of the image on my own, but it's never shown. Image just stays blank. That's the class: class FirstBackgroundImage : UIImageView { required init(coder aDecoder: NSCoder) { super.init(coder: aDecoder) self.backgroundColor = UIColor.redColor() } override init() { super.init() self.backgroundColor = UIColor.redColor() } override required init(image: UIImage!) { super.init(image: image) self.backgroundColor = UIColor.redColor() } } That's how i connected it:

  • Compiling .xsl files into .class files

    - by Alex Ciminian
    I'm currently working on a Java web project (Spring) which involves heavy use of xsl transformations. The stylesheets seldom change, so they are currently cached. I was thinking of improving performance by compiling the xsl-s into class files so they wouldn't have to be interpreted on each request. I'm new to Java, so I don't really know the ecosystem that well. What's the best way of doing this (libraries, methods etc.)? Thanks, Alex

  • Production debugging: Is there a less intrusive way than WinDbg?

    - by Alex
    Hi, I was wondering if there is a less intrusive way to analyze a running, managed process in production environments. Less intrusive meaning: No delay of execution when attaching the debugger. No delay of execution when getting basic stats like running threads. In the Java world there is a such a tool part of the JDK. I was wondering if there're similar tools in the .NET world. Any ideas?

    The process of making a large image out of mosaic of smaller image “pixels” is certainly nothing new; this rendition of Starry Night using images from the Hubble telescope, however, is a particularly fitting use of the technique. Crafted by Alex H. Parker, a researcher at the Harvard-Smithsonian Center for Astrophysics, on evenings when cloud cover prevented him from conducting his research, the image is a carefully constructed mosaic of NASA supplied photos from the Hubble telescope program.

  • Test-Drive ASP.NET MVC Review

    - by Ben Griswold
    A few years back I started dallying with test-driven development, but I never fully committed to the practice. This wasn’t because I didn’t believe in the value of TDD; it was more a matter of not completely understanding how to incorporate “test first” into my everyday development. Back in my web forms days, I could point fingers at the framework for my ignorance and laziness. After all, web forms weren’t exactly designed for testability so who could blame me for not embracing TDD in those conditions, right? But when I switched to ASP.NET MVC and quickly found myself fresh out of excuses and it became instantly clear that it was time to get my head around red-green-refactor once and for all or I would regretfully miss out on one of the biggest selling points the new framework had to offer. I have previously written about how I learned ASP.NET MVC. It was primarily hands on learning but I did read a couple of ASP.NET MVC books along the way. The books I read dedicated a chapter or two to TDD and they certainly addressed the benefits of TDD and how MVC was designed with testability in mind, but TDD was merely an afterthought compared to, well, teaching one how to code the model, view and controller. This approach made some sense, and I learned a bunch about MVC from those books, but when it came to TDD the books were just a teaser and an opportunity missed.  But then I got lucky – Jonathan McCracken contacted me and asked if I’d review his book, Test-Drive ASP.NET MVC, and it was just what I needed to get over the TDD hump. As the title suggests, Test-Drive ASP.NET MVC takes a different approach to learning MVC as it focuses on testing right from the very start. McCracken wastes no time and swiftly familiarizes us with the framework by building out a trivial Quote-O-Matic application and then dedicates the better part of his book to testing first – first by explaining TDD and then coding a full-featured Getting Organized application inspired by David Allen’s popular book, Getting Things Done. If you are a learn-by-example kind of coder (like me), you will instantly appreciate and enjoy McCracken’s style – its fast-moving, pragmatic and focused on only the most relevant information required to get you going with ASP.NET MVC and TDD. The book continues with the test-first theme but McCracken moves away from the sample application and incorporates other practical skills like persisting models with NHibernate, leveraging Inversion of Control with the IControllerFactory and building a RESTful web service. What I most appreciated about this section was McCracken’s use of and praise for open source libraries like Rhino Mocks, SQLite and StructureMap (to name just a few) and productivity tools like ReSharper, Web Platform Installer and ASP.NET SQL Server Setup Wizard.  McCracken’s emphasis on real world, pragmatic development was clearly demonstrated in every tool choice, straight-forward code block and developer tip. Whether one is already familiar with the tools/tips or not, McCracken’s thought process is easily understood and appreciated. The final section of the book walks the reader through security and deployment – everything from error handling and logging with ELMAH, to ASP.NET Health Monitoring, to using MSBuild with automated builds, to the deployment  of ASP.NET MVC to various web environments. These chapters, like those prior, offer enough information and explanation to simply help you get the job done.  Do I believe Test-Drive ASP.NET MVC will turn you into an expert MVC developer overnight?  Well, no.  I don’t think any book can make that claim.  If that were possible, I think book list prices would skyrocket!  That said, Test-Drive ASP.NET MVC provides a solid foundation and a unique (and dare I say necessary) approach to learning ASP.NET MVC.  Along the way McCracken shares loads of very practical software development tips and references numerous tools and libraries. The bottom line is it’s a great ASP.NET MVC primer – if you’re new to ASP.NET MVC it’s just what you need to get started.  Do I believe Test-Drive ASP.NET MVC will give you everything you need to start employing TDD in your everyday development?  Well, I used to think that learning TDD required a lot of practice and, if you’re lucky enough, the guidance of a mentor or coach.  I used to think that one couldn’t learn TDD from a book alone. Well, I’m still no pro, but I’m testing first now and Jonathan McCracken and his book, Test-Drive ASP.NET MVC, played a big part in making this happen.  If you are an MVC developer and a TDD newb, Test-Drive ASP.NET MVC is just the book for you.

  • openVPN GUI does not run error about error opening registry for reading HKLM\SOFTWARE\OpenVPN

    - by Coder
    I'm trying to run OpenVPN as a portable application and to that effect i have installed it on a Windows 7 machine, copied the files to another windows 7 machine and manually restored the registry settings using a .reg file. Whenever i try to run open vpn GUI i get the following error error opening registry for reading HKLM\SOFTWARE\OpenVPN I have verified that the key mentioned is indeed in the registry at the correct location with the correct values yet the GUI still complains. I have tried running the gui as an administrator (i'm logged in as an administrator) and also the compatibility modes but none helped. I have also tried openVPN portable "OpenVPNPortable_1.6.6.paf.exe" and it has the same problem. Can anybody help me with this issue?

  • LiteSpeed enable Access-Control-Allow-Origin (no response header on CORS request)

    - by Joe Coder Guy
    Seriously, I can't find a single page discussing this for litespeed. Using this format in the htaccess "Header set Access-Control-Allow-Origin http://aSite.com" (and https) sends the setting in the http response header, but I still get the "XMLHttpRequest cannot load https://aSite.com/aFile.php. Origin aSite.com is not allowed by Access-Control-Allow-Origin" error when trying to access https from http origin. Also, I receive no response header for https, only that message shows up in Chrome. Is the server still blocking it even though I've sent the proper headers? I read elsewhere that it helps to add these terms Access-Control-Allow-Headers X-Requested-With Access-Control-Allow-Methods OPTIONS, GET, POST Access-Control-Allow-Headers Content-Type, Depth, User-Agent, X-File-Size, X-Requested-With, If-Modified-Since, X-File-Name, Cache-Control but I don't see these in my headers. Using these, my PHP files aren't even reached (because they register no errors or anything), so it looks like it comes from the server only, but what do I know. Thanks in advance! Update Since no response header, Prashant seems to suggest it's a server issue in his error since it worked on another server. http://stackoverflow.com/questions/11953132/no-response-obtained-while-implementing-cors Anyone know how to flip this switch? Headers work now Bad litespeed format. Should look like this. Still being denied though. Header set Access-Control-Allow-Headers X-Requested-With Header set Access-Control-Allow-Methods OPTIONS Header set Access-Control-Allow-Methods GET Header set Access-Control-Allow-Methods POST Header set Access-Control-Allow-Headers Content-Type Header set Access-Control-Allow-Headers Depth Header set Access-Control-Allow-Headers User-Agent Header set Access-Control-Allow-Headers X-File-Size Header set Access-Control-Allow-Headers X-Requested-With Header set Access-Control-Allow-Headers If-Modified-Since Header set Access-Control-Allow-Headers X-File-Name Header set Access-Control-Allow-Headers Cache-Control

  • passenger-status - ERROR: Phusion Passenger doesn't seem to be running

    - by Casual Coder
    My server is: Server version: Apache/2.2.11 (Ubuntu) Server built: Aug 16 2010 17:44:11 My ruby version ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-linux]. I've installed passenger 3.0.7 via RubyGems. I've run passenger-install-apache2-module and everything went fine. I've modified configuration (load module, edit virtualhost etc.) and restarted Apache. Module is loading fine (apache does not complain). But Passenger is obviously not working: sudo passenger-status ERROR: Phusion Passenger doesn't seem to be running. How can I get it working ? Edit 1: /etc/apache2/mods-enabled/passenger.load LoadModule passenger_module /usr/lib/ruby/gems/1.9.1/gems/passenger-3.0.7/ext/apache2/mod_passenger.so Root of passenger: passenger-config --root /usr/lib/ruby/gems/1.9.1/gems/passenger-3.0.7 Apache VirtualHost sub URI configuration in /etc/apache2/sites-enabled/railsapps: <VirtualHost <IP ADDRESS>:80> ServerAdmin webmaster@localhost ServerName my.server.name PassengerRoot /usr/lib/ruby/gems/1.9.1/gems/passenger-3.0.7 PassengerRuby /usr/bin/ruby RailsEnv development DocumentRoot /www/vhosts/railsapps <Directory /www/vhosts/railsapps> Options FollowSymlinks -MultiViews AllowOverride None Order allow,deny Allow from all </Directory> RailsBaseURI /siteA <Directory /www/vhosts/railsapps/siteA> Options -MultiViews AllowOverride All Order allow,deny Allow from all </Directory> RailsBaseURI /siteB <Directory /www/vhosts/railsapps/siteB> AllowOverride All Options -MultiViews Order allow,deny Allow from all </Directory> LogLevel info ErrorLog /var/log/apache2/railsapps_error.log CustomLog /var/log/apache2/railsapps_access.log combined </VirtualHost> Of course as in 'users guide apache.html' siteA and siteB are symlinks to siteA/public and siteB/public absolute paths respectively. Edit 2: In logs there is nothing related to passenger. Permissions are also fine (read and executable) on directories in paths. Even if it was some misconfiguration or permission problem isn't passenger suppose to be running? I mean sudo passenger-status should at least output --- general information ---. When I place some test html file in railsapps directory it is served fine. /var/log/apache2/railsapps_error.log [Sun Jun 19 12:19:08 2011] [error] [client <IP>] Directory index forbidden by Options directive: /www/vhosts/railsapps/siteA/ [Sun Jun 19 12:19:08 2011] [error] [client <IP>] File does not exist: /www/vhosts/railsapps/favicon.ico
