• Favourite Features of VS 2010

  - by Noldorin

  With the general public release of Visual Studio 2010 Beta 2 today, this latest version has created a lot of hype and interest. Indeed, the opinion I've gauged is that VS 2010 has resolved a great deal of the minor flaws left over from previous versions, as well as added some particularly useful new code editor and project development tools (in particular the Premium/Ultimate versions). My question here is: what are you favourite new features in VS 2010 that have really got you excited? Or similarly, what are the flaws of VS 2008 that you are most glad to have resolved? There is a wealth of changes in VS 2010, of course, but these are some of the ones that have interested me most (about which I know!). Integrated support for F# (with multi-targeting for .NET 2.0 - 4.0)/ Much improved WPF designer. The VS 2008 was more than a bit buggy at times. Great improvements to the code editor, such as call hierarchy viewing. A decent add-in framework. A greatly expanded testing framework (now capable of database testing, for example) in Premium/Ultimate. Project planning and modelling features in Premium/Ultimate. If I could request one point/feature per post, I think that would be best, so we could vote them individually.

• How to view shell commands used by eclipse "run configurations"

  - by gmale

  Given a "run configuration" in Eclipse, I want to print out the associated shell command that would be used to run it. For example: Right now, in Eclipse, if I click "play" it will run: mvn assembly:directory -Dmaven.test.skip=true I don't see that command, I just know that's what the IDE must run, at some point. However, some of the other run configurations are far more complex with long classpaths and virtual machine options and, frankly, sometimes I have no idea what the equivalent shell command would be (particularly when it comes to Flex). There must be some way to access the shell command that would be associated with a "Run Configuration" in Eclipse/Flex Builder. This information must be available, which leads me to believe someone has written a plugin to display it. Or maybe there's already an option built into Eclipse for accessing this. So is there a way to, essentially, convert an Eclipse run configuration into a shell command? (for context only: I'm asking because I'm writing a bash script that automates everything I do, during development--from populating the Database all the way to opening Firefox and clearing the cache before running the web app. So every command I run from the IDE needs to exist in the script. Some are tricky to figure out.)

• How to tell what account my webservice is running under in Visual Studio 2005

  - by John Galt

  I'm going a little nuts trying to understand the doc on impersonation and delegation and the question has come up what account my webservice is running under. I am logged as myDomainName\johna on my development workstation called JOHNXP. From Vstudio2005 I start my webservice via Debug and the wsdl page comes up in my browser. From Task Manager, I see the following while sitting at a breakpoint in my .asmx code: aspnet_wp.exe pid=1316 UserName=ASPNET devenv.exe pid=3304 UserName=johna The IIS Directory Security tab for the Virtual Directory that hosts my ws.asmx code has "Enable Anonymous access" UNCHECKED and has "Integrated Windows Authentication" CHECKED. So when the MSDN people state "you must configure the user account under which the server process runs", what would they be refering to in the case of my little webservice described above? I am quoting from: http://msdn.microsoft.com/en-us/library/aa302400.aspx Ultimately, I want this webservice of mine to impersonate whatever authenticated domain user browses through to an invoke of my webservice. My webservice in turn consumes another ASMX webservice on a different server (but same domain). I need this remote webservice to use the impersonated domain user credentials (not those of my webservice on JOHNXP). So its getting a little snarly for me to understand this and I see I am unclear about the account my web service uses. I think it is ASPNET in IIS 5.1 on WinXP but not sure.

• Really cool way to create custom UITabBar for iPhone app?

  - by ludicco

  Hi, I am doing a lot of researching lately about how to get a different looking with nice effects UITabBar on my iPhone app, but unfortunately I am only finding things on how to replace background color etc. Well, I've checked out this app called Momento which is pretty cool and presents a very slick tabBar: So there are a couple of elements here I would like to ask you guys if you could help me by giving me the right directions on how to get a similar effect :) Arrow above items: as you can see this app has this animated arrow that runs above the selected item with a very smooth animation. Selected Stated of the item's image is not that blue-ish default one neither the default state which displays in a different shade of brown and gray version. nice Items separators with beveled vertical lines. diferrent background image for the tabBar different height for the tabBar At this point after some research I am able to set the height and background image by subclassing UITabBarController but I'm still not sure on how to accomplish the other items specially the first one related to the nice arrow effect. If someone knows about a very good tutorial on how to do this it would be great for clarifying what can or can't be done by subclassing the UITabBarController and specially if can be done in Interface Builder :) I am just starting on this world off app development for iOS so if you could help me on that it would be really appreciated Thanks a lot in advance

• WCF service reference namespace differs from original

  - by Thorarin

  I'm having a problem regarding namespaces used by my service references. I have a number of WCF services, say with the namespace MyCompany.Services.MyProduct (the actual namespaces are longer). As part of the product, I'm also providing a sample C# .NET website. This web application uses the namespace MyCompany.MyProduct. During initial development, the service was added as a project reference to the website and uses directly. I used a factory pattern that returns an object instance that implements MyCompany.Services.MyProduct.IMyService. So far, so good. Now I want to change this to use an actual service reference. After adding the reference and typing MyCompany.Services.MyProduct in the namespace textbox, it generates classes in the namespace MyCompany.MyProduct.MyCompany.Services.MyProduct. BAD! I don't want to have to change using directives in several places just because I'm using a proxy class. So I tried prepending the namespace with global::, but that is not accepted. Note that I hadn't even deleted the original assembly references yet, and "reuse types" is enabled, but no reusing was done, apparently. However, I don't want to keep the assembly references around in my sample website for it to work anyway. The only solution I've come up with so far is setting the default namespace for my web application to MyCompany (because it cannot be empty), and adding the service reference as Services.MyProduct. Suppose that a customer wants to use my sample website as a starting point, and they change the default namespace to OtherCompany.Whatever, this will obviously break my workaround. Is there a good solution to this problem? To summarize: I want to generate a service reference proxy in the original namespace, without referencing the assembly. Note: I have seen this question, but there was no solution provided that is acceptable for my use case. Edit: As John Saunders suggested, I've submitted some feedback to Microsoft about this: Feedback item @ Microsoft Connect

• Clickonce redirect

  - by David Hagan

  Is it possible to deploy an application (using an existing clickonce deployment URL, such that users update to that version) which changes the deployment URL of the deployed application? The scenario is that I have a deployed client (A), which is stable and has been in use for over a year, and a new client (B), which is in development and will be used. However, B and A have different UIDs so that they can both be deployed on the same system together. At some point in the future, I'd like to automatically migrate users who have been using A to B, but I'd hope that Clickonce is well-designed enough to not upgrade A to B if I place B's install files in A's install directory (because it should be checking those UIDs). I know that a C# application that's been deployed through clickonce has some access to its own deployment method, and I'm wondering whether I'm able to change the upgrade-location. I'm hoping to do this quietly without much involvement of the user (and I understand that quiet redirects are heavily frowned upon, for good reasons) and am wondering whether anyone has any experience of trying to modify an installed clickonce's deployment/upgrade information with an update.

• What are the differences between mapping,binding and parsing?

  - by sfrj

  I am starting to learn web-services in java EE6. I did web development before, but never nothing related to web services. All is new to me and the books and the tutorials i find in the web are to technical. I started learning about .xsd schemas and also .xml. In that topic i feel confident, i understand what are the schemas used for and what validation means. Now my next step is learning about JAX-B(Java Api for XML Binding). I rode some about it and i did also some practice in my IDE. But i have lots of basic doubts, that make me stuck and cannot feel confident to continue to the next topic. Ill appreciate a lot if someone could explain me well my doubts: What does it mean mapping and what is a mapping tool? What does it mean binding and what is a binding tool? What does it mean parsing and what is a parsing tool? How is JAX-B related to mapping,binding and parsing? I am seeking for a good answer built by you, not just a copy paste from google(Ive already been online a few hours and only got confused).

• How to store session values with Node.js and mongodb?

  - by Tirithen

  How do I get sessions working with Node.js, [email protected] and mongodb? I'm now trying to use connect-mongo like this: var config = require('../config'), express = require('express'), MongoStore = require('connect-mongo'), server = express.createServer(); server.configure(function() { server.use(express.logger()); server.use(express.methodOverride()); server.use(express.static(config.staticPath)); server.use(express.bodyParser()); server.use(express.cookieParser()); server.use(express.session({ store: new MongoStore({ db: config.db }), secret: config.salt })); }); server.configure('development', function() { server.use(express.errorHandler({ dumpExceptions: true, showStack: true })); }); server.configure('production', function() { server.use(express.errorHandler()); }); server.set('views', __dirname + '/../views'); server.set('view engine', 'jade'); server.listen(config.port); I'm then, in a server.get callback trying to use req.session.test = 'hello'; to store that value in the session, but it's not stored between the requests. It probobly takes something more that this to store session values, how? Is there a better documented module than connect-mongo?

• Programming time schedule for porting a program.

  - by Lothar

  I'm working on a large program which has an abstracted GUI API. It is very GUI based, many dialogs and a few nasty features which rely heavily on the message flow of the GUI (correct sequences of focus/mouse/active handling etc.) - not easy to port I now want to port it from the currently used FOX Toolkit to native Cocoa/MFC. I give myself a timeframe until the end of the year but my main work will be to continue development work with the existing toolkit, but there is no planned release for end customers before both tasks are done. My question is how should i spend my time? Stop working on the main program and do a 90% port (about 3 month) of the GUI first Splitting everything into smaller sessions of one month each. Assigning Monday/Tuesday to the GUI project and the rest of the week for the app. Finishing the App first, then port. I think there are three arguments which i need to balance. Motivation, i want to see something going on on both projects Brain Input Overflow, both tasks require a lot of detail information in my brain and sometimes enough is just enough. I guess the porting is intervowen so porting would also require a lot of code changes in the existing code and the new code that will be written in the meantime.

• Safari doesn't detect my Extension Certificate

  - by Questor

  Hello, all! I have registered for the Safari Development Program and have a valid Apple ID. I've followed all the steps given by Apple. The problem is that Windows XP (Service Pack 2) does not recognize the command 'certreq', whereas the instructions said it would work on any Windows machine. However, the command 'certreq' was working on Windows Vista on the machine of my co-worker's, I downloaded the certificate (the .cer file) and installed it and Safari detected it. However, I don't have Windows Vista. I installed Windows 7 now on my machine, the command 'certreq' works and I have the Safari Extension Certificate (the .cer file) but when I open Safari's Extension Builder, my certificate does not appear there. I entered mmc in Start -- Run and checked if the certificate was installed there. It was in the 'Other People' but not in 'Personal'. Even on Internet Explorer 7+, when I go to Tools -- Internet Options -- Content (Tab) -- Certificates, the certificate is not there in the Personal tab, (WHEREAS IT GOT INSTALLED IN THE PERSONAL FOLDER AUTOMATICALLY IN WINDOWS VISTA). I tried importing the certificate (the .cer file) into the Peronal folder, the import is successful but still neither does it appear in the personal folder nor does Safari recognize/detect it when I go to the Extension Builder. ANY HELP?! I need to make an extension for my office project and the deadline is approaching. I really need to get it done. Thanks a million in anticipation.

• Code Coverage tool for BlackBerry

  - by Skrud

  I'm looking for a code coverage tool that I can use with a BlackBerry application. I'm using J2ME-Unit for Unit Testing and I want to see how much of my code is being covered by my tests. I've tried using Cobertura for J2ME but after days of wrestling with it I failed to get any results from it. (I believe that the instrumentation is un-done by the RAPC compilation). And despite this message, the project seems to be dead. I've looked at JInjector but the project seems very incomplete. There is little (if any) documentation and although it claims to be able to work with BlackBerry projects, I haven't seen any places where it has been used for that purpose. I've played with the project quite a bit but to no avail. I've also tried the "Coverage" view in the BlackBerry JDE, even though I use Eclipse for development. The view stays permanently blank, regardless of clicking "Refresh" and running the application from the JDE. I've looked at most of the tools on this SO thread, but they won't work with J2ME/BlackBerry projects. Has anyone had any success with any code coverage tools on the BlackBerry? If so, what tools have you used? How have you used them? If anyone has managed to get JInjector or Cobertura for J2ME to work with a BlackBerry project, what did you have to do to get it working?

• Accessing a share point site using the object model.

  - by Prashanth

  Hi I am trying to access a share point site using the SP object model from a console application. I am trying to do something like this.. SPSite site = new SPSite(sitePath) //Operations go here This works fine when the share point site and the console app are on the same machine. However when the console app and the site are on different machines, I get an error "The Web application at "http://server/url" could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application" Here are the things that I have already done: 1) I have tried accessing the site via both IP address as well as machine name, assuming that it could be a DNS resolution issue. 2) Initially I impersonated using a farm admin account, still i could not access. Then I added myself as the farm admin, still no joy. 4) The site is accessible via IE. So it is not a permission issue I guess. 5) I have tried almost all the solutions suggested by various links obtained by googling the error message. I am trying this on share point 2010. A similar issue occurs on 2007 also. Sometimes its kind of frustrating to do SharePoint development , since I get the feeling of stumbling from one error to the next, with no clue as to what could be wrong and the error messages not being helpful in the least :(

• Getting basepath from view in zend framework

  - by mobmad

  Case: you're developing a site with Zend Framework and need relative links to the folder the webapp is deployed in. I.e. mysite.com/folder online and localhost:8080 under development. The following works nice in controllers regardless of deployed location: $this->_helper->redirector->gotoSimple($action, $controller, $module, $params); And the following inside a viewscript, ie. index.phtml: <a href="<?php echo $this->url(array('controller'=>'index', 'action' => 'index'), null, true); ?>"> But how do I get the correct basepath when linking to images or stylesheets? (in a layout.phtml file, for example): <img src='<?php echo WHAT_TO_TYPE_HERE; ?>images/logo.png' /> and $this->headLink()->appendStylesheet( WHAT_TO_TYPE_HERE . 'css/default.css'); WHAT_TO_TYPE_HERE should be replaced with something that gives <img src="/folder/images/logo.png />` on mysite.com and `<img src="/images/logo.png /> on localhost

• Python on Mac: Fink? MacPorts? Builtin? Homebrew? Binary installer?

  - by BastiBechtold

  For the last few days, I have been trying to use Python for some audio development. The thing is, Mac OSX does not handle uninstalling stuff well. Actually, there is no way to uninstall anything. Once it is on your system, you better pray that it didn't do any funny stuff. Hence, I don't really want to rely on installer packages for Python. So I turn to Homebrew and install Python using Homebrew. Works fabulously. Using pip, Numpy, SciPy, Matplotlib were no (big) problem, either. Now I want to play audio. There is a host of different packages out there, but pip does not seem willing to install any. But, there is a binary distribution for PyGame, which I guess should work with the built-in Python. Hence my question: What would you do? Would you just install the binary distributions and hope that they interoperate well and never need uninstalling? Would you hack your way through whichever package control management system you prefer and deal with its problems? Something else?

• How to get the most out of a 3 month intern?

  - by firoso

  We've got a software engineering intern coming in who's fairly competent and shows promise. There's one catch: we have him for 3 months full time and can't count on anything past that. He still has a year of school left, which is why we can't say for sure that we have him past 3 months. We have a specific project we're putting him on. How can we maximize his productivity while still giving him a positive learning experience? He wants to learn about development cycles and real-world software engineering. Anything that you think would be critical that you wish you had learned earlier? Nearly six months later: He's preformed admirably and even I have learned a lot from him. Thank you all for the input. Now I want to provide feedback to YOU! He has benefited most from sitting down and writing code. However, he has had a nasty history of bad software engineering practices which I'm trying to replace with good habits (properly finishing a method before moving on, not hacking code together, proper error channeling, etc). He has also really gained a lot by feeling involved in design decisions, even if most of the time they're related to my own design plans.

• Automatic Deployment of Windows Application

  - by dileepkrishnan

  Hi, We have setup continuos integration in our development environment using SVN, CC.Net, MSBuild and Nunit. Now, we want to automate the process of moving (copying) builds from one stage to another like this: Whenever a new build succeeds in Dev, that should be copied automatically to the QA server (a folder on the QA server, to be exact) Whenever a QA build succeeds tests in QA, that QA build should be copied to the UAT server (a folder on the UAT server, to be exact). This should be implemented as a process (a CC task, for example) which we can start when QA succeeds. Whenever a UAT build succeeds tests in UAT, that should be copied to the PROD server (a folder on the PROD server, to be exact). This should be implemented as a process (a CC task, for example) which we can start when UAT succeeds. How do I implement this? Can this be done using CC.Net alone? Or, can this be done using MSBuild? Or, do I need to employ both? Please advise what exactly needs to be done. Thanks Dileep Krishnan

• How To Create a Flexible Plug-In Architecture?

  - by justkt

  A repeating theme in my development work has been the use of or creation of an in-house plug-in architecture. I've seen it approached many ways - configuration files (XML, .conf, and so on), inheritance frameworks, database information, libraries, and others. In my experience: A database isn't a great place to store your configuration information, especially co-mingled with data Attempting this with an inheritance hierarchy requires knowledge about the plug-ins to be coded in, meaning the plug-in architecture isn't all that dynamic Configuration files work well for providing simple information, but can't handle more complex behaviors Libraries seem to work well, but the one-way dependencies have to be carefully created. As I seek to learn from the various architectures I've worked with, I'm also looking to the community for suggestions. How have you implemented a solid plug-in architecture? What was your worst failure (or the worst failure you've seen)? What would you do if you were going to implement a new plug-in architecture? What SDK or open source project that you've worked with has the best example of a good architecture? A few examples I've been finding on my own: Perl's Module::Plugable An SO question with a list for Java (including Sever Provider Interfaces) An SO question for C++ pointing to a Dr. Dobbs article These examples seem to play to various language strengths. Is a good plugin architecture necessarily tied to the language? Is it best to use tools to create a plugin architecture, or to do it on one's own following models?

• The perfect web UI framework (with Microsoft stack?) - architecture question?

  - by Igorek

  I'm looking for suggestions for the following issue, and I realize there is really not going to be a perfect answer to my question: I have a UI built in WinForms.NET (v4.0 framework) with WCF back-end and EF4 model objects, that I am looking to port to the web. UI is not huge and is not super complex and is structured well. But it is not a super simple system either. I am looking to pick a technology stack for the web-frontend that will target desktop & partially mobile platforms, provide a good development platform to build on, and facilitate code reuse across UI and back-end tiers... I would rather avoid: custom coding of UI-centric scripts, because they are hard to debug, non-compiled, usually a maintenance nightmare, almost always start to contain business logic, and duplicate some of the logic that back-end tiers have (especially validation) custom-coding for Desktop Web and Mobile Web UI's separately (although I realize that mobile web UI will likely contain fewer of data-entry screens and more reporting screens) non-.NET technology stacks I would love to: target the reporting capabilities of the system toward mobile web browsers not have to write a single line of script (javascript, jquery, etc.) utilize a good collection of controls that produces an elegant UI use .NET for everything The way I see it right now, I need to re-write this app in Silverlight, utilize a 3rd party UI framework like Telerik, and re-do the reports UI again for mobile platforms separately. However, I'm rather concerned about the shelf-life of Silverlight and the needed to deploy a different architecture to deal with mobile platform. Is there an ASP.NET/MVC/Ajax architecture/framework/library that would allow me to get at the power of .NET and without painful (imho) client-side scripting, while providing a decent user experience Thank you

• Using capistrano to deploy from different git branches

  - by Toms Mikoss

  I am using capistrano to deploy a RoR application. The codebase is in a git repository, and branching is widely used in development. Capistrano uses deploy.rb file for it's settings, one of them being the branch to deploy from. My problem is this: let's say I create a new branch A from master. The deploy file will reference master branch. I edit that, so A can be deployed to test environment. I finish working on the feature, and merge branch A into master. Since the deploy.rb file from A is fresher, it gets merged in and now the deploy.rb in master branch references A. Time to edit again. That's a lot of seemingly unnecessary manual editing - the parameter should always match current branch name. On top of that, it is easy to forget to edit the settings each and every time. What would be the best way to automate this process? Edit: Turns out someone already had done exactly what I needed.

• Why does this extension method throw a NullReferenceException in VB.NET?

  - by Dan

  From previous experience I had been under the impression that it's perfectly legal (though perhaps not advisable) to call extension methods on a null instance. So in C#, this code compiles and runs: // code in static class static bool IsNull(this object obj) { return obj == null; } // code elsewhere object x = null; bool exists = !x.IsNull(); However, I was just putting together a little suite of example code for the other members of my development team (we just upgraded to .NET 3.5 and I've been assigned the task of getting the team up to speed on some of the new features available to us), and I wrote what I thought was the VB.NET equivalent of the above code, only to discover that it actually throws a NullReferenceException. The code I wrote was this: ' code in module ' <Extension()> _ Function IsNull(ByVal obj As Object) As Boolean Return obj Is Nothing End Function ' code elsewhere ' Dim exampleObject As Object = Nothing Dim exists As Boolean = Not exampleObject.IsNull() The debugger stops right there, as if I'd called an instance method. Am I doing something wrong (e.g., is there some subtle difference in the way I defined the extension method between C# and VB.NET)? Is it actually not legal to call an extension method on a null instance in VB.NET, though it's legal in C#? (I would have thought this was a .NET thing as opposed to a language-specific thing, but perhaps I was wrong.) Can anybody explain this one to me?

• What is an elegant way to set up a leiningen project that requires different dependencies based on the build platform?

  - by Savanni D'Gerinel

  In order to do some multi-platform GUI development, I have just switched from GTK + Clojure (because it looks like the Java bindings for GTK never got ported to Windows) to SWT + Clojure. So far, so good in that I have gotten an uberjar built for Linux. The catch, though, is that I want to build an uberjar for Windows and I am trying to figure out a clean way to manage the project.clj file. At first, I thought I would set the classpath to point to the SWT libraries and then build the uberjar. This would require that I set a classpath to the SWT libraries before running the jar, but I would likely need a launcher script, anyway. However, leiningen seems to ignore the classpath in this instance because it always reports that Currently, project.clj looks like this for me: (defproject alyra.mana-punk/character "1.0.0-SNAPSHOT" :description "FIXME: write" :dependencies [[org.clojure/clojure "1.2.0"] [org.clojure/clojure-contrib "1.2.0"] [org.eclipse/swt-gtk-linux-x86 "3.5.2"]] :main alyra.mana-punk.character.core) The relevant line is the org.eclipse/swt-gtk-linux-x86 line. If I want to make an uberjar for Windows, I have to depend on org.eclipse/swt-win32-win32-x86, and another one for x86-64, and so on and so forth. My current solution is to simply create a separate branch for each build environment with a different project.clj. This seems kinda like using a semi to deliver a single gallon of milk, but I am using bazaar for version control, so branching and repeated integrations are easy. Maybe the better way is to have a project.linux.clj, project.win32.clj, etc, but I do not see any way to tell leiningen which project descriptor to use. What are other (preferably more elegant) ways to set up such an environment?

• iOS Simulator is black on app execution

  - by Terryn

  I am running xcode 5.1.1 and have been trying to learn objective C / iOS development. Right now whenever I try to run my code on the emulator (I do not have an actual device atm) it comes up with a black screen. Code can be found here. Compiling and running gives me the following error: 2014-08-23 10:42:57.429 Calculator[1862:60b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<XYZViewController 0xe436640> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key didgetPressed.' *** First throw call stack: ( 0 CoreFoundation 0x017ed1e4 __exceptionPreprocess + 180 1 libobjc.A.dylib 0x0156c8e5 objc_exception_throw + 44 2 CoreFoundation 0x0187cfe1 -[NSException raise] + 17 3 Foundation 0x0122cd9e -[NSObject(NSKeyValueCoding) setValue:forUndefinedKey:] + 282 4 Foundation 0x011991d7 _NSSetUsingKeyValueSetter + 88 5 Foundation 0x01198731 -[NSObject(NSKeyValueCoding) setValue:forKey:] + 267 6 Foundation 0x011fab0a -[NSObject(NSKeyValueCoding) setValue:forKeyPath:] + 412 7 UIKit 0x004e31f4 -[UIRuntimeOutletConnection connect] + 106 8 libobjc.A.dylib 0x0157e7de -[NSObject performSelector:] + 62 9 CoreFoundation 0x017e876a -[NSArray makeObjectsPerformSelector:] + 314 10 UIKit 0x004e1d4d -[UINib instantiateWithOwner:options:] + 1417 11 UIKit 0x0034a6f5 -[UIViewController _loadViewFromNibNamed:bundle:] + 280 12 UIKit 0x0034ae9d -[UIViewController loadView] + 302 13 UIKit 0x0034b0d3 -[UIViewController loadViewIfRequired] + 78 14 UIKit 0x0034b5d9 -[UIViewController view] + 35 15 UIKit 0x0026b267 -[UIWindow addRootViewControllerViewIfPossible] + 66 16 UIKit 0x0026b5ef -[UIWindow _setHidden:forced:] + 312 17 UIKit 0x0026b86b -[UIWindow _orderFrontWithoutMakingKey] + 49 18 UIKit 0x002763c8 -[UIWindow makeKeyAndVisible] + 65 19 UIKit 0x00226bc0 -[UIApplication _callInitializationDelegatesForURL:payload:suspended:] + 2097 20 UIKit 0x0022b667 -[UIApplication _runWithURL:payload:launchOrientation:statusBarStyle:statusBarHidden:] + 824 21 UIKit 0x0023ff92 -[UIApplication handleEvent:withNewEvent:] + 3517 22 UIKit 0x00240555 -[UIApplication sendEvent:] + 85 23 UIKit 0x0022d250 _UIApplicationHandleEvent + 683 24 GraphicsServices 0x037e2f02 _PurpleEventCallback + 776 25 GraphicsServices 0x037e2a0d PurpleEventCallback + 46 26 CoreFoundation 0x01768ca5 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 53 27 CoreFoundation 0x017689db __CFRunLoopDoSource1 + 523 28 CoreFoundation 0x0179368c __CFRunLoopRun + 2156 29 CoreFoundation 0x017929d3 CFRunLoopRunSpecific + 467 30 CoreFoundation 0x017927eb CFRunLoopRunInMode + 123 31 UIKit 0x0022ad9c -[UIApplication _run] + 840 32 UIKit 0x0022cf9b UIApplicationMain + 1225 33 Calculator 0x00002c8d main + 141 34 libdyld.dylib 0x01e34701 start + 1 35 ??? 0x00000001 0x0 + 1 ) libc++abi.dylib: terminating with uncaught exception of type NSException (lldb) I have attempted the following things, and so far nothing has worked 1) checked the deployment info, it has the main interface set to main 2) double checked all break points to turn them off and disabled all of them through Debug-Disable Breakpoints 3) Reset Content and Settings on the iOS Simulator. 4) Checked the issue with the LLDB Debugger, however from what I have read the issue is no longer present with the 5.1.1 xcode. 5) checked the local host is still set to 127.0.0.1 Thanks! - Terryn

• Exporting database from external server (without SSH access)

  - by Derek Carlisle

  Our current website is hosted by the design agency who originally built the website, however we are bringing the development of the website in house therefore need to export the database from their server and import it to ours. We have FTP and phpMyAdmin access but don't have SSH access to the server. I was hoping to run a PHP script that would mysql dump the database, compress it and then copy it across to our server using scp: $backupFile = $_SERVER['DOCUMENT_ROOT'].'/backup' . date("Y-m-d-H-i-s") . '.gz'; system("mysqldump -h DB_HOST -u DB_USER -pDB_PASS DB_NAME | gzip > $backupFile"); exec("sshpass -p PASSWORD scp -r -P PORT_NUMBER $backupFile [email protected]:/path/to/directory/"); I have ran this locally from the command line and it worked fine, although I had to install sshpass (the hosting server might not have this installed). Also, I was hoping to run it from the browser as I don't have command line access on the hosting server, however it didn't work, no errors produced though. Can you anyone recommend how I can export from the server that I don't have SSH access to and import to my server? Thanks

• Call ASP.NET 2.0 Server side code from Javascript

  - by Kannabiran

  I'm struggling with this for the past 3 days. I need to call asp.net serverside code from Javascript when the user closes the browser. I'm using the following code to accomplish this. In my asp.net form I have various validation controls. Even if there are some validation errors, When I close the form the server side code works perfectly in my development box(windows 7). But the same code doesnt work in my production environment(windows server). Does it have something to do with the Validation summary or Validation controls. The button control has Causes validation set to false. So even if there is a validation error still my form will post back. Am I correct? I suspect the form is not getting post back to the server when there is a validation error. But i'm disabling all the validation controls in the javascript before calling the button click event. Can someone throw some light on this issue. There are few blogs which suggests to use JQUERY, AJAX (Pagemethods and script manager). function ConfirmClose(e) { var evtobj = window.event ? event : e; if (evtobj == e) { //firefox if (!evtobj.clientY) { evtobj.returnValue = message; } } else { //IE if (evtobj.clientY < 0) { DisablePageValidators(); document.getElementById('<%# buttonBrowserCloseClick.ClientID %>').click(); } } } function DisablePageValidators() { if ((typeof (Page_Validators) != "undefined") && (Page_Validators != null)) { var i; for (i = 0; i < Page_Validators.length; i++) { ValidatorEnable(Page_Validators[i], false); } } } //HTML <div style="display:none" > <asp:Button ID="buttonBrowserCloseClick" runat="server" onclick="buttonBrowserCloseClick_Click" Text="Button" Width="141px" CausesValidation="False" /> //Server Code protected void buttonBrowserCloseClick_Click(object sender, EventArgs e) { //Some C# code goes here }

• How can I run Ruby specs and/or tests in MacVim without locking up MacVim?

  - by Henry

  About 6 months ago I switched from TextMate to MacVim for all of my development work, which primarily consists of coding in Ruby, Ruby on Rails and JavaScript. With TextMate, whenever I needed to run a spec or a test, I could just command+R on the test or spec file and another window would open and the results would be displayed with the 'pretty' format applied. If the spec or test was a lengthy one, I could just continue working with the codebase since the test/spec was running in a separate process/window. After the test ran, I could click through the results directly to the corresponding line in the spec file. Tim Pope's excellent rails.vim plugin comes very close to emulating this behavior within the MacVim environment. Running :Rake when the current buffer is a test or spec runs the file then splits the buffer to display the results. You can navigate through the results and key through to the corresponding spot in the file. The problem with the rails.vim approach is that it locks up the MacVim window while the test runs. This can be an issue with big apps that might have a lot of setup/teardown built into the tests. Also, the visual red/green html results that TextMate displays (via --format pretty, I'm assuming) is a bit easier to scan than the split window. This guy came close about 18 mos ago: http://cassiomarques.wordpress.com/2009/01/09/running-rspec-files-from-vim-showing-the-results-in-firefox/ The script he has worked with a bit of hacking, but the tests still ran within MacVim and locked up the current window. Any ideas on how to fully replicate the TextMate behavior described above in MacVim? Thanks!
