• Configuring 32-Bit ASP.NET Application on a 64-Bit IIS Server

  - by Tim

  Hello, I’m trying to install a 32-bit ASP.NET application onto a 64-bit IIS server running on Windows Server 2008. This is a clean installation of the operating system with no other applications installed. As a prerequisite for our installation, we run the 32-bit version of aspnet_regiis –i It fails with the following message: The error indicates that IIS is not installed on the machine. Please install IIS before using this tool. Additionally: IIS is definitely installed. The 64 bit version of aspnet_regiis runs cleanly without warnings. “Enable 32 bit applications” is set to True in the DefaultAppPool’s Advanced Settings. The IIS Metabase and IIS 6 configuration compatibility” component is installed. We have a test VM where this error occurs as well as test VM where both the 32 bit and 64 bit versions of aspnet_regiis run without errors. We've had no luck distinguishing the differences between the two test VMs. We have struggled with this issue for several days to no avail. Any suggestions would be greatly appreciated!

• Embedding a CMS in an MVC Web App

  - by Mr Snuffle

  I'm working on a website for searching for businesses, then displaying a listing page. We've been toying with the idea of letting the clients manage their listing page using an external CMS. I'm not sure how often this is done, or if it's even best practice. Ideally, we want to be able to setup a listing on our website, then give the clients access to an external CRM when they can manage their listing page. We then want to embed this custom page within our website, possibly using an iframe (which will come along with it's own set of complications). We'd like this integration to be as seamless as possible. I'd personally prefer it if we could directly inject the HTML into our own page and bypass an iframe all together, but I don't know of any CMS hosting services that provide the interface for such a thing. We've experimented a little with Squarespace, and we can get a fairly clean version of someone's page which would be well suited for an iframe. I'm wondering if anyone else has looked and integrating an external hosting CMS into a website (in this case, we're using ASP.NET MVC). We'd also want to automate the creation of accounts on this external CMS, so when a user signed up we could just point them to the website with some login details. I have no idea if anyone offers a service like this, but any recommendations would be greatly appreciated. We could host a service ourself too, but the aim is to have an external system that clients can use to manage their pages. Cheers, James

• Database migration pattern for Java?

  - by Eno

  Im working on some database migration code in Java. Im also using a factory pattern so I can use different kinds of databases. And each kind of database im using implements a common interface. What I would like to do is have a migration check that is internal to the class and runs some database schema update code automatically. The actual update is pretty straight forward (I check schema version in a table and compare against a constant in my app to decide whether to migrate or not and between which versions of schema). To make this automatic I was thinking the test should live inside (or be called from) the constructor. OK, fair enough, that's simple enough. My problem is that I dont want the test to run every single time I instantiate a database object (it runs a query so having it run on every construction is not efficient). So maybe this should be a class static method? I guess my question is, what is a good design pattern for this type of problem? There ought to be a clean way to ensure the migration test runs only once OR is super-efficient.

• What Language Feature Can You Just Not Live Without?

  - by akdom

  I always miss python's built-in doc strings when working in other languages. I know this may seem odd, but it allows me to cut down significantly on excess comments while still providing a clean description of my code and any interfaces therein. What Language Feature Can You Just Not Live Without? If someone were building a new language and they asked you what one feature they absolutely must include, what would it be? This is getting kind of long, so I figured I'd do my best to summarize: Paraphrased to be language agnostic. If you know of a language which uses something mentioned, please at it in the parenthesis to the right of the feature. And if you have a better format for this list, by all means try it out (if it doesn't seem to work, I'll just roll back).

• tikz: set appropriate x value for a node

  - by basweber

  This question resulted from the question here I want to produce a curly brace which spans some lines of text. The problem is that I have to align the x coordinate manually, which is not a clean solution. Currently I use \begin{frame}{Example} \begin{itemize} \item The long Issue 1 \tikz[remember picture] \node[coordinate,yshift=0.7em] (n1) {}; \\ spanning 2 lines \item Issue 2 \tikz[remember picture] \node[coordinate, xshift=1.597cm] (n2) {}; \item Issue 3 \end{itemize} \visible<2->{ \begin{tikzpicture}[overlay,remember picture] \draw[thick,decorate,decoration={brace,amplitude=5pt}] (n1) -- (n2) node[midway, right=4pt] {One and two are cool}; \end{tikzpicture} } % end visible \end{frame} which produces the desired result: The unsatisfying thing is, that I had to figure out the xshift value of 1.597cm by trial and error (more or less) Without xshift argument the result is: I guess there is an elegant way to avoid the explicit xshift value. The best way would it imho be to calculate the maximum x value of two nodes and use this, (as already suggested by Geoff) But it would already be very handy to be able to explicitly define the absolute xvalues of both nodes while keeping their current y values. This would avoid the fiddly procedure of adapting the third post decimal position to ensure that the brace looks vertical.

• Oracle Data Provider and casting

  - by mrjoltcola

  I use Oracle's specific data provider, not the Microsoft provider that is being discontinued. The thing I've found about ODP.NET is how picky it is with data types. Where JDBC and other ADO providers just convert and make things work, ODP.NET will throw an invalid cast exception unless you get it exactly right. Consider this code: String strSQL = "SELECT DOCUMENT_SEQ.NEXTVAL FROM DUAL"; OracleCommand cmd = new OracleCommand(strSQL, conn); reader = cmd.ExecuteReader(); if (reader != null && reader.Read()) { Int64 id = reader.GetInt64(0); return id; } Due to ODP.NET's pickiness on conversion, this doesn't work. My usual options are: 1) Retrieve into a Decimal and return it with a cast to an Int64 (I don't like this because Decimal is just overkill, and at least once I remember reading it was deprecated...) Decimal id = reader.GetDecimal(0); return (Int64)id; 2) Or cast in the SQL statement to make sure it fits into Int64, like NUMBER(18) String strSQL = "SELECT CAST(DOCUMENT_SEQ.NEXTVAL AS NUMBER(18)) FROM DUAL"; I do (2), because I feel its just not clean pulling a number into a .NET Decimal when my domain types are Int32 or Int64. Other providers I've used are nice (smart) enough to do the conversion on the fly. Any suggestions from the ODP.NET gurus?

• gwt maven war plugin configuration problem

• How can I place validating constraints on my method input parameters?

  - by rcampbell

  Here is the typical way of accomplishing this goal: public void myContractualMethod(final String x, final Set<String> y) { if ((x == null) || (x.isEmpty())) { throw new IllegalArgumentException("x cannot be null or empty"); } if (y == null) { throw new IllegalArgumentException("y cannot be null"); } // Now I can actually start writing purposeful // code to accomplish the goal of this method I think this solution is ugly. Your methods quickly fill up with boilerplate code checking the valid input parameters contract, obscuring the heart of the method. Here's what I'd like to have: public void myContractualMethod(@NotNull @NotEmpty final String x, @NotNull final Set<String> y) { // Now I have a clean method body that isn't obscured by // contract checking If those annotations look like JSR 303/Bean Validation Spec, it's because I borrowed them. Unfortunitely they don't seem to work this way; they are intended for annotating instance variables, then running the object through a validator. Which of the many Java design-by-contract frameworks provide the closest functionality to my "like to have" example? The exceptions that get thrown should be runtime exceptions (like IllegalArgumentExceptions) so encapsulation isn't broken.

• Using Git to work with subversion: Ignoring modifications to tracked files

  - by Chris Nicola

  I am currently working with a subversion repository but I am using git to work locally on my machine. It makes work much easier, but it also makes some of the bad behavior going on in the subversion repo quite glaring and that creates problems for me. There is a somewhat complex local build process after pulling down the code and it creates (and unfortunately modifies) a number of files. Obviously these changes are not meant to be committed back to the repository. Unfortunately the build process is actually modifying some tracked files (yes, most likely because someone mistakenly committed these build artifacts at some point to the subversion repository). Since these are modifications adding them to my ignore file does nothing for me. I can avoid checking these changes back it, I simple don't stage or commit them, but having unstaged local changes means I can't rebase without first cleaning them up. What I would like to know is if there any way to ignore future changes to a set of tracked files? Alternatively, is there another way to handle the problem I am having, or will I just have to tell whoever checked in these files to clean them up?

• How do you remove invalid hexadecimal characters from an XML-based data source prior to constructing

  - by Oppositional

  Is there any easy/general way to clean an XML based data source prior to using it in an XmlReader so that I can gracefully consume XML data that is non-conformant to the hexadecimal character restrictions placed on XML? Note: The solution needs to handle XML data sources that use character encodings other than UTF-8, e.g. by specifying the character encoding at the XML document declaration. Not mangling the character encoding of the source while stripping invalid hexadecimal characters has been a major sticking point. The removal of invalid hexadecimal characters should only remove hexadecimal encoded values, as you can often find href values in data that happens to contains a string that would be a string match for a hexadecimal character. Background: I need to consume an XML-based data source that conforms to a specific format (think Atom or RSS feeds), but want to be able to consume data sources that have been published which contain invalid hexadecimal characters per the XML specification. In .NET if you have a Stream that represents the XML data source, and then attempt to parse it using an XmlReader and/or XPathDocument, an exception is raised due to the inclusion of invalid hexadecimal characters in the XML data. My current attempt to resolve this issue is to parse the Stream as a string and use a regular expression to remove and/or replace the invalid hexadecimal characters, but I am looking for a more performant solution.

• Temporary debug releases and final application releases

  - by baron

  I have a quick question regarding debug and release in VS 2008. I have an app i've been working on - its not yet complete but the bulk of the functionality is there. So basically i'm trying to give a copy of it now to the person helping with documentation - just so they can have a play and get the feel for what i've made. Now the question is how to provide it to them. I was told to just copy the .exe out of the debug/bin folder and put that onto USB. But when testing, if I run this .exe anywhere else (outside of this folder) it crashes. I've now worked out why this is: var path = ConfigurationManager.AppSettings["PathToUse"]; var files = Directory.GetFiles(path); throws a null reference, so that App.config file is not being used. If I copy that file in with the .exe it works again. So actually my question is regarding the best way to manage this situation. What is the best way to provide a working copy to people, and, is there a reference on preparing apps for release - so everything is packaged together and installed in a clean structured folder heirarchy?

• how to force operating system to give java more memory?

  - by Denny

  Hello, I've got problem with java jar files and memory. I use netbeans 6.7 to develop an application and this application need more memory to run because it converts another files. Whenever this application convert a 6-10 mb file, it'll crash. So I set netbeans VM Options : -Xms32m -Xmx256m and the application can convert 6-10mb files with no problem. I Clean and Build the project so it can make a jar file of my application. I run the jar on my computer and use jconsole to monitor the memory. The maximum memory to use by the application shows 256 mb. But whenever I move it to some other computers, it shows 65-66 mb on jconsole and the application will crash when convert 6-10 mb files. So I need to use command prompt : java -jar -Xmx256m myjar.jar to execute the jar with maximum memory Why it can be happen, in my computer the maximum memory shows 256 mb but on another computer 65-66 mb? Can I force another computer to give extra maximum memory to my application? Thank you for your answer. I'm sorry for my inadequate English. If you all find my question is hard to understand, please let me know. Best Regards Denny ps: fyi the computer i used to develop the application have 2gb ram, on the other computers i tested have 1-2 gb ram.

• What specific features of LabView are frustrating to you?

  - by Underflow

  Please bear with me: this isn't a language debate or a flame. It's a real request for opinions. Occasionally, I have to help educate a traditional text coder in how to think in LabVIEW (LV). Often during this process, I get to hear about how LV sucks. Rarely is this insight accompanied by rational observations other than "Language X is just so much better!". While this statement is satisfying to them, it doesn't help me understand what is frustrating them. So, for those of you with LabVIEW and text language experience, what specific things about LV drive you nuts? ------ Summaries ------- Thanks for all the answers! Some of the issues are answered in the comments below, some exist on other sites, and some are just genuine problems with LV. In the spirit of the original question, I'm not going to try to answer all of these here: check LAVA or NI's website, and you'll be pleasantly surprised at how many of these things can be overcome. Unintentional concurrency No access to tradition text manipulation tools Binary-only source code control Difficult to branch and merge Too many open windows Text has cleaner/clearer/more expressive syntax Clean coding requires a lot of time and manipulation Large, difficult to access API/palette system Mouse required File namespacing: no duplicate files with the same name in memory LV objects are natively by-value only Requires dev environment to view code Lack of zoom Slow startup Memory pig "Giant" code is difficult to work with UI lockup is easy to do Trackpads and LV don't mix well String manipulation is graphically bloated Limited UI customization "Hidden" primitives (yes, these exist) Lack of official metaprogramming capability (not for much longer, though) Lack of unicode support [1]: http://www.lavag.org LAVA

• Unity to dispose of object

  - by Johan Levin

  Is there a way to make Unit dispose property-injected objects as part of the Teardown? The background is that I am working on an application that uses ASP.NET MVC 2, Unity and WCF. We have written our own MVC controller factory that uses unity to instantiate the controller and WCF proxies are injected using the [Dependency] attribute on public properties of the controller. At the end of the page life cycle the ReleaseController method of the controller factory is called and we call IUnityContainer.Teardown(theMvcController). At that point the controller is disposed as expected but I also need to dispose the injected wcf-proxies. (Actually I need to call Close and/or Abort on them and not Dispose but that is a later problem.) I could of course override the controllers' Dispose methods and clean up the proxies there, but I don't want the controllers to have to know about the lifecycles of the injected interfaces or even that they refer to WCF proxies. If I need to write code myself for this - what would be the best extension point? I'd appreciate any pointer.

  Hi, I'm trying to upload an iPhone app binary to iTunesConnect and keep getting the following error message "The binary you upload was invalid. the file was not a valid zip file". I had an app upload ok recently but this app is having problems. So after a while I carefully went through the following steps trying to make sure everything was ok. Any help is appreciated. The steps: renamed the project (Project-Rename... enter name into Rename project to:) to release name making sure the name has no spaces. Cleaned project Make sure references in build setting reflect new app name Create new app ID matching project name in iPhone Provisioning Portal Destroyed old developer and distributer provisioning profiles in Provisioning Portal, in XCode and on iPhone. Create new development provisioning profile using new app name. Install development provisioning profile into XCode 8) Build (Release) for iPhone OS 3.1.3 (highest my phone will upgrade to, I'm assuming current released version) Builds, Installs and Runs on actual iPhone: To me this implys App and developer ID's are OK. Create a distributor provisioning profile using existing Distributer ID. Install distributer ID into XCode Clean Checked that "Code Signing Identity" and "Any iPhone OS Device" lines in Build settings are set to Distributor ID Build for release for OS 3.1.3 Check Build results to make sure code is signed with Distributor Profile Reveal .app file and compress (alt click Compress "appName.app") Upload to iTunes connect Gives "The binary you uploaded was invalid.

• Modify Executing Jar file

  - by pinkynobrain

  Hello Stack Overflow friends. I have a simple problem which i fear doesnt have a simple solution and i need advice as to how to proceed. I am developing a java application packaged as and executable JAR but it requires to modify some of its JAR file contents during execution. At this stage i hit a problem because some OS lock the file preventing writes to it. It is essential that the user sees an updated version of the jar file by the time the application exits allthough i can be pretty flexible as to how to achieve this. A clean and efficient solution is obviously prefereable but portability is the only hard requirement. The following are three approaches i can see to solving the problem, feel free to comment on them or suggest others. Tell Java to unlock the JAR file for writing(this doesnt seem possible but it would be the easyest solution) Copy the executable class files to a tempory file on application startup, use a class loader to load these files and unload the ones from the initial JAR file.(Not had much experience with the classloaders but hopefully the JVM would then be smart enough to realize that the original JAR is nolonger in use and so unlock it) Put a Second executable JAR File inside the First, on startup extract the inner jar to e temporaryfile, invoke a new java process and pass it the location of the Outer JAR, first process exits, second process modifys the Outer jar unincumbered.(This will work but im not sure there is a platform independant way of one java app invoking another) I know this is a weird question but any help would be appreciated.

• ASP.NET MVC2 DataAnnotations not catching error

  - by Paul Connolly

  Can somebody help me to figure out why DataAnnotations will not work with my MVC2 project in VS 2008 SP1? Here's the situation.. I uninstalled VS2008 and MVC1, then reinstalled VS2008 SP1 and .NET 3.5 SP1 and MVC2. Now when I create a clean project as soon as it has to hit the DataAnnotations Dll (e.g. say when I go to Register.aspx it fails at the first "LabelFor" that it encounters. I can overcome this by changing the "Copy Local" property of the dll to True but this then creates a conflict with the same dll in the Tests project. If then I delete the test project and try agan, it runs but does not catch any validation failures. I have gone right back to basics and followed the step by step ScottGu Datavalidation tutorial at : http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx And at the "Et viola" bit where we usually go "Whoa! cool!" I say "It never caught!". Any Ideas?

• Can I have two separate projects, 1 WebForms and 1 ASP.NET MVC, to both point to the same domain?

  - by Hamman359

  Is it possible to setup two separate projects, 1 WebForms and 1 ASP.NET MVC, to both point to the same domain? i.e. both point to different pages within www.somesite.com. Here's some background on the application and why I'm asking. This is a brownfield application that is currently 2.0 WebForms and is full of WebFormy 'goodness' (i.e. ObjectDataSources, FormView controls, UpdatePanels, etc...) There are lost of other 'fun' things in the code base like 600+ Stored Procedures and 200+ line methods in the business layer code that get data from the DB via stored proc, do some processing on the data, build an HTML string using string concatenation and then return that string to the UI layer. What we are planning on doing is developing new features in MVC and slowly converting the existing features over to MVC one at a time. As part of this transition, we will also be re-writing the layers below the UI to clean up the mess there and to do things like replace the stored procedures with NHibernate and introduce an IOC container. I know that you can run WebForms and MVC side-by-side in the same project, however, because we will be making wholesale changes to the way we do many things throughout our entire development stack, I'd like the new stuff to be a completely separate project within the solution. This should help serve as very visual reminder that this is a different way of doing things than before and make it easier to remove the old code as it is no longer needed. What I don't know is, is this even possible? Can two separate project point to the same domain? Here's an quick example of what I'm thinking: www.somesite.com/orders.aspx?id=123 (Orders page from existing WebForms project) www.somesite.com/customer/987 (Customer page from new MVC project)

• Why are changes to coffeescript files not being compiled when my Rails 3.2.0 app is in development mode?

  - by ben

  Normally, any changes I make to .js.coffee files in my Rails 3.2.0 app in development mode take effect when I refresh the page. All of a sudden, this is not happening. If I do rake assets:precompile, then the changes are shown, but then if I do rake assets:clean they go back to not being shown. What is causing this? Edit: Restarting the server makes the changes show. Why isn't this happening automatically as before? Edit: Here is my development.rb Myapp::Application.configure do # Settings specified here will take precedence over those in config/application.rb # In the development environment your application's code is reloaded on # every request. This slows down response time but is perfect for development # since you don't have to restart the web server when you make code changes. config.cache_classes = false # Log error messages when you accidentally call methods on nil. config.whiny_nils = true # Show full error reports and disable caching config.consider_all_requests_local = true config.action_controller.perform_caching = false # Don't care if the mailer can't send config.action_mailer.raise_delivery_errors = false # Print deprecation notices to the Rails logger config.active_support.deprecation = :log # Only use best-standards-support built into browsers config.action_dispatch.best_standards_support = :builtin # Raise exception on mass assignment protection for Active Record models config.active_record.mass_assignment_sanitizer = :strict # Log the query plan for queries taking more than this (works # with SQLite, MySQL, and PostgreSQL) config.active_record.auto_explain_threshold_in_seconds = 0.5 # Do not compress assets config.assets.compress = false # Expands the lines which load the assets config.assets.debug = true config.action_mailer.default_url_options = { :host => 'localhost:3000' } config.log_level = :warn end

• Question about WeakReferences

  - by Impz0r

  Hey there, I've got a question regarding WeakReferences. I'm right now in the process of writing a "Resource Manager" who hast to keep references to created texture objects. I have a Dictionary like: Dictionary<uint, WeakReference> Where the first is, as you allready may guessed, the Resource Id and the second param is a WeakReference to the Resource itself. Right now my Resources do have a method to free themselfes from their Owner (i.e. Resource Manager). They do so in calling a method at the Resource Manger while passing a this reference to it. The ResMgr does lookup if it is a resource he keeps bookmark of and if so, does something like this: WeakReference result; if (m_Resources.TryGetValue(ResourceId, out result)) { if (result.IsAlive) return; (result.Target as Resource).free(); // free for good m_Resources.Remove(ResourceId); } The Problem I'm having is that the part after: if (result.IsAlive) is never reached because there are still leftover references to the Resource. The thing is, I do only have one Reference of the Resource in question and it releases itself like: resource.free(); // calls internally its owner (i.e. ResMgr) resource = null; I guess the left over reference would be the "resource" variable, but I cannot set it to null, because I do have to call free first. Quite a dilema... Well what I wanted to achive with this is a Resource Manager who keeps references to its owning Resources and release them ONLY if there is no reference left to not screw up something. Any idea how I may solve this in a clean fashion? Thanks in advance! Mfg Imp

• Git checkout doesn't change anything, and it's getting very frustrating

  - by Josh

  I really like git. At least, I like the idea of git. Being able to checkout my master project as a separate branch where I can change whatever I want without risk of screwing everything else up is awesome. But it's not working. Every time I checkout a branch to another branch, make changes to the one branch, and then checkout the original branch, I still have all the files and changes that happened in the other branch. This is getting extremely frustrating. I've read that this can happen when you have files open in the IDE while doing this, but I've been pretty careful about that and both closed the files in the IDE, closed the IDE, and shut down my rails server before switching branches, and this still happens. Also, running 'git clean -f' either deletes everything that happened after some arbitrary commit (and randomly, at that), or, as in the latest case, didn't change anything back to its original state. I thought I was using git correctly, but at this point, I'm at my wit's end here. I'm trying to work with a bunch of experimental code using a stable version of my project, but I keep having to manually track down and fix all the changes I made. Any ideas or suggestions? git checkout -b photo_tagging git branch # to make sure it's right # make a bunch of changes, creations, etc git status # see what's changed since before git add . # approve of the changes, I guess, since if I do git commit after this, it says no changes git commit -m 'these are changes I made' git checkout master git branch #=> *master # look at files, tags_controller is still there, added in photo_tagging # and code added in photo_tagging branch are still there in *master This seems to happen whether I do a commit or not on the branch.

• Cleaner/more effective way to use modulus and creating columned lists

  - by WmasterJ

  I currently have a list (<ul>) of people that I have divided up into two columns. But after finishing the code for it I keept wondering if there is a more effective or clean way to do the same thing. echo "<table class='area_list'><tr>"; // Loop users within areas, divided up in 2 columns $count = count($areaArray); for($i=0 ; $i<$count ; $i++) { // get the modulus value + ceil for uneven numbers $rowCalc = ($i+1) % ceil($count/2); if ($rowCalc == 1) echo "<td><ul>"; // OUTPUT the actual list item echo "<li>{$users[$uid]->profile_lastname}</li>"; if ($rowCalc == 0 && $i!=0) echo "</ul></td>"; } echo "</table>"; Any ideas of how to make this cleaner or do it in another way?

• How do I setup NInject? (I'm getting can't resolve "Bind", in the line "Bind<IWeapon>().To<Sword>()

  - by Greg

  Hi, I'm getting confused in the doco how I should be setting up Ninject. I'm seeing different ways of doing it, some v2 versus v1 confusion probably included... Question - What is the best way in my WinForms application to set things up for NInject (i.e. what are the few lines of code required). I'm assuming this would go into the MainForm Load method. In other words what code do I have to have prior to getting to: Bind<IWeapon>().To<Sword>(); I have the following code, so effectively I just want to get clarification on the setup and bind code that would be required in my MainForm.Load() to end up with a concrete Samurai instance? internal interface IWeapon { void Hit(string target); } class Sword : IWeapon { public void Hit(string target) { Console.WriteLine("Chopped {0} clean in half", target); } } class Samurai { private IWeapon _weapon; [Inject] public Samurai(IWeapon weapon) { _weapon = weapon; } public void Attack(string target) { _weapon.Hit(target); } } thanks PS. I've tried the following code, however I can't resolve the "Bind". Where does this come from? what DLL or "using" statement would I be missing? private void MainForm_Load(object sender, EventArgs e) { Bind<IWeapon>().To<Sword>(); // <== *** CAN NOT RESOLVE Bind *** IKernel kernel = new StandardKernel(); var samurai = kernel.Get<Samurai>();
