• Xcode: code loses syntax coloring

  - by ColorMeFamous

  I find that in various situations Objective-C code in Xcode 3.1 (Leopard) can fail to get appropriate syntax coloring after typing or lose coloring that it had. This isn't just a "refresh" issue with new custom symbols -- but affects Cocoa framework symbols as well. Sometimes CMD-a to select all text on the code page will make the coloring (re)appear, sometimes double-clicking on a line to select it will work, sometimes I have to add/delete a space in a symbol to get that symbol to (re)color. Rebuilding, or closing/reopening the project may or may not work. Is this a known issue with Xcode? For something so annoying to me, I'm not finding the plentiful discussions of it on SO and elsewhere I'd expect. And is there any command to force global syntax recoloring?

• Problem running gems in OS X

  - by akarnid

  I'm running Snow Leopard, and installed a custom built Ruby according to the guide here: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard . My ruby binary lives in usr/local/bin/ruby and my gems are installed in /usr/local/bin/gem . My gem env looks like so: RUBY VERSION: 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0] - INSTALLATION DIRECTORY: /Library/Ruby/Gems/1.8 - RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby - EXECUTABLE DIRECTORY: /usr/bin I think I may have borked the install since all actions taked on gems give the error: ERROR: While executing gem ... (Errno::EEXIST) File exists - /usr/local/bin/ruby How do you edit the environment variables for the gem environment? And for those of you on OS X and using ruby AND gems, what did you use to get yourself up and running? I'm thinking of just nuking everything and starting anew.

• How to mock test a web service in PHPUnit across multiple tests?

  - by scraton

  I am attempting to test a web service interface class using PHPUnit. Basically, this class makes calls to a SoapClient object. I am attempting to test this class in PHPUnit using the "getMockFromWsdl" method described here: http://www.phpunit.de/manual/current/en/test-doubles.html#test-doubles.stubbing-and-mocking-web-services However, since I want to test multiple methods from this same class, every time I setup the object, I also have to setup the mock WSDL SoapClient object. This is causing a fatal error to be thrown: Fatal error: Cannot redeclare class xxxx in C:\web\php5\PEAR\PHPUnit\Framework\TestCase.php(1227) : eval()'d code on line 15 How can I use the same mock object across multiple tests without having to regenerate it off the WSDL each time? That seems to be the problem.

• BNRPersistence on the iPhone, and NSDocument

  - by jammur

  I'm trying to get BNRPersistence running in an iPhone app, but I'm having a problem that I have no idea how to solve. Keep in mind I'm relatively new to iPhone dev. The problem is that BNRStoreDocument subclasses NSDocument, which exists in the Cocoa framework and thus isn't available on the iPhone. So obviously I'm getting compile errors that it can't find NSDocument. The developer of BNRPersistence states that it works on the iPhone, so I'm sure there a solution, I just don't what it is. Any help would be greatly appreciated!

• What to write in "Web location" field when starting an "New website" in Visual Studio 2010?

  - by Ivan

  I want a website to be deployed automatically to a local IIS (built in Windows XP Pro SP3), avoiding VisualStudio-built-in server if possible. I'd like development source files to be stored in a project folder outside wwwroot (I wouldn't mind built files to be copied to wwwroot each time I press F5). I don't store my projects inside default directories inside "My documents". What should I specify as in "Web location" when starting an "New website" in Visual Studio 2010? A deployment path in wwwroot, a folder where I'd like to save my project, or something else? I want the website to be a part of a complex solution in VS 2010, also icludinc a class libray project, a WinForms application project, a Windows Service project and a common Entitity Framework data model.

• Which C# 4.0 Book would you purchase, and why?

  - by Jeremy

  I'm currently looking at purchasing a few C# 4.0 books, namely: Essential C# 4.0 by Mark Michaelis or C# 4.0 Unleashed by Bart De Smet. I am aware that both books are yet to be released, but would you consider purchasing either of these books, or would you recommend another? Thanks for your time. Clarification: I'm not a .net Ninja, but I do have 8+ years experience with the framework & related languages. So I'm generally looking for in-depth books. I also train/instruct the rest of my organisation generally 6 - 12 months after each .net release. Each of the developers I train has the same or more .net experience then myself. Once again thank you all for your time. Update: Thank you everyone for your responses. I've decided to purchase both books along with Visual C# 2010 Recipes: A Problem-Solution Approach, as suggested by Waleed Al Balooshi.

• Best toolkit for new Web application (odd requirements)

  - by ireadit

  I need to write a new application, and have no experience with any new technology, framework, or language. Here are the requirements: HTML front end (best if it's cross-browser friendly) Web deployable, but also ideally want to be able to install as standalone on a desktop SQL Server database Ideally, would like to use a good (and easy) AJAX toolkit with widgets Ideally, would like to be able to write in ASP.Net but later (or concurrently) also write in Java. This is a big concern, as I would like to not have to rewrite the whole thing. Is there a toolkit I can use that makes this cross-platform requirement easier? All suggestions and comments are much appreciated. Thank you.

• I cannot connect to SQL Server Express using VB.NET

  - by konin

  Can someone tell me what I am missing? I am using this connection string to connect to my database and still it won't connect: Dim str As String = "Provider = .NET Framework Data Provider for SQL Server; Data Source=C:\Users\konin\Documents\UHMS\bin\Debug\UHMS.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True" This is the process I used to get the data source: right-click the database select properties and click select data source I hope I am clear enough. Thanks for reading. Edit: Error Message is as follows: unable to connect to database please contact administrator

• Skype Mac API - Use AppleScript or 5 year old API?

  - by Andrew

  I have a x86_64 app that I would like to have optionally read Skype status messages. However, the 5 year old skype mac framework is 32-bit, and if there is a way to have that compile within a 64-bit app, I haven't found it. My question is, basically, how should I go about doing this? I really only need to get and set the USERSTATUS AWAY/ONLINE string. Using AppleScript, a "Should Skype allow this" dialog pops up... every time. This is highly inefficient and downright irritating. Advice? I'm considering writing a 32-bit CLI wrapper, but that seems like overkill.

• how to deploy wcf-service on iis 6.0

  - by Walter

  I have IIS 6.0 on Windows Server 2003. I installed .Net 3.5 and 4 beta 2. "Normal" asp things are working (perfect). But when I try to navigate to my service (/myServer/MyService.svc) I got a 404. Page not found. To be exact, I got a 404 2 "Web service extension lockdown policy prevents this request." I used ServiceModelReg.exe /ia to make sure that the extension I known and I checked the configuration using: admin-Tools, iis, home-tab, configuration, executable-box, and there: extension: .svc, path: c:\windows\microsoft.net\framework\v4.0.210... verbs: all verbs So everything seems ok. But I still get a 404-2

• Using mozilla plataform to develop desktop applications

  - by RHaguiuda

  Hi everyone. From what It seems mozilla plataform was designed to be used focused in web development (browsers, e-mail clients, instant message...). I want to use Mozilla plataform to develop desktop applications that need most access to computer serial port and some applications that have nothing to do with web. Im considering mozilla because its multi-plataform and easy to extend using themes and extensions. Is it possible to program a serial terminal for example using mozilla? Does mozilla have any class ou framework that do this job or I`ll have to code for windows API? Thank you!

• Can PyAMF support service deployment by way of the filesystem?

  - by Chris R

  I'm evaluating PyAMF to replace our current PHP (ugh) AMF services framework, and I'm unable to find the one crucial piece of information that would allow me to provide a compelling use case for changing over: Right now, new PHP AMF services are deployed simply by putting the .php files in the filesystem; the next time they're accessed, the new service is in play. Removal of a service is as simple as deleting the .php file that provided it, and updating it is correspondingly simple. I need that same ease-of-deployment from PyAMF. If we have to rewrite our installers to deploy these services, it'll be a nonstarter. So, what I need to know is, can PyAMF support new service discovery by way of the filesystem, can it support service upgrading and removal by way of same, and if so, what is the best way to set it up to do this? I'm open to any of the various server options; I can easily have cherrypy, django, whatever installed and running on its own, and even -- with a bit more sturm nd drang -- have mod_python or mod_wsgi made available.

• Webwork actions, the lifecycle of variables declared in the action class.

  - by Sam

  Hi all, I'm using the webwork framework (JIRA plugin development) and was wondering about the lifecycle of the variables in the action class. I have a few private variables in the action class that are set when during the doDefault() method. These are used in the input view to set up jqGrid columns and then when the user has entered some data they click submit which puts the grid data into a hidden input. The next thing that happens is the doValidation() method is called before the doExecute(), which displays the input view if there are any errors. The problem is that the variables set up in the doDefault() method are now null. Can anyone explain to me how the lifecycle of variables works in the webwork actions? Cheers

• Failed opening 'SiteTest: Firefox.php' when running Yii Functional Test

  - by Phelios

  Warning: include(): Failed opening 'SiteTest: Firefox.php' for inclusion ... \yii\framework\YiiBase.php on line 418 Yii v1.1.10 PHPUnit v3.6.10 PHPUnit_Selenium v 1.2.6 I get this error when trying to run the example on the book "Agile Web Development with Yii 1.1 and PHP5" I kind of feel that there is a problem with the phrase SiteTest:, it shouldn't be there. But, how do I fix this? UPDATE (SOLVED): Apparently, the problem is not the warning shown above, but there is another error down the road. It says that "curl_init()" is undefined. I already enabled the php_curl extension, but the PHP from CLI is not using the same .ini file as the apache one. So, after I enabled the php_curl in the CLI version of the ini, it works fine now (still giving the warning, but the test is running).

• SQL Server CE 3.5 SP1 Stored Procedures

  - by Robert

  I have been tasked with taking an existing WinForms application and modifying it to work in an "occasionally-connected" mode. This was to be achieved with SQL Server CE 3.5 on a user's laptop and sync the server and client either via SQL Server Merge Replication or utilizing Microsoft's Sync Framework. Currently, the application connects to our SQL Server and retrieves, inserts, updates data using stored procedures. I have read that SQL Server CE does not support stored procedures. Does this mean that all my stored procedures will need to be converted to straight SQL statements, either in my code or as a query inside a tableadapter? If this is true, what are my alternatives?

• How to post Arabic characters in PHP

  - by Peter Stuart

  Okay, So I am writing an OpenCart extension that must allow Arabic characters when posting data. Whenever I post ????? the print_r($_POST) returns with this: u0645u0631u062du0628u0627 I check the HTML header and it has this: <meta charset="UTF-8" /> I checked the PHP file that triggers all SQL queries and it has this code: mysql_query("SET NAMES 'utf8'", $this->link); mysql_query("SET CHARACTER SET utf8", $this->link); mysql_query("SET CHARACTER_SET_CONNECTION=utf8", $this->link); This is in my form tag: <form action="<?php echo $action; ?>" method="post" enctype="multipart/form-data" id="form" accept-charset="utf-8"> I can't think of what else I am doing wrong. The rest of the OpenCart framework supports UTF8 and arabic characters. It is just in this instance where I can't post anything arabic? Could someone please help me? Many Thanks Peter

• Helper functions & prototype methods to replace heavy frameworks?

  - by Rob

  All frameworks aside, what are some of the common helper functions/prototype methods you use on a daily basis? Please note I am not arguing against frameworks. I've simply found that the majority of what I do on a daily basis can, most often, be done with a few dozen Array, String and Element.prototype methods. With the addition of a few helper functions like $ (getElementsById) and $$$ (getElementsByClass), I am able to satisfy some of the core benefits, however basic, of a much heavier framework. If you were to collect a small library of basic methods and functions to replace the core functionality of some of the popular frameworks, what would they be?

• 70-536 exam, same for 2.0 and 3.5

  - by Fermin

  Hi, I have recently booked the 70-536 Application Development Foundation exam. On the above link it says that "If you are a .NET 2.0 developer, you do not need to learn .NET 3.5 to pass Exam 70-536; conversely, if you are a .NET 3.5 developer, you do not need to review .NET 2.0 to pass the exam.". How does this work? Do you choose 3.5 or 2.0 (I'm wanting it for 3.5) at the start of the exam or does it only ask questions that are pertinent to both versions of the framework?

• Is there a DOS command for verifying what version of .NET is installed

  - by Travis

  I have set of scripts for doing scripted installs. You can use the scripts on any server 2008 machine. However, I need to check if .NET 3.5 has been installed (before the scripts run) using a dos batch file. Is that possible? I know I can check if a file in the C:\WINDOWS\Microsoft.NET\Framework\v3.5 exists, but it would be nice to have something a little more reliable. I would like to check if it's actually installed, not just if the dir/file exists. Hope that makes sense. Thanks in advance.

• Simple ADO.NET C# Stored Procedure Generator

  - by Ron

  I am using Visual Studio 2005, Sql Server 2005, C#, ADO.NET. We have a very large database and routinely adding new stored procedures. I am tired of writing the C# wrapper code for these stored procedures, seems like there should be some simple utility or Add In that would allow me to simply point to a stored procedure and generate some generic C# code. I am not looking for some big ORM or data access layer framework. The company I am doing this for is not interested in moving to something like that right now. Just wanting something to take the grunt work out of writing the C# wrappers around stored procedures. Again, prefer that we do not have to include in other 3rd party libraries, etc. Any ideas?

• Django: Admin with multiple sites & languages

  - by lazerscience

  Hi everybody! I'm supposed to build some Django apps, that allow you to administer multiple sites through one backend. The contrib.sites framework is quite perfect for my purposes. I can run multiple instances of manage.py with different settings for each site; but how should django's admin deal with different settings for different sites, eg. if they have different sets of languages, a different (default) language? So there are some problem s to face if you have to work on objects coming from different sites in one admin... I think settings.ADMIN_FOR is supposed to be quite helpful for cases like this, but theres hardly any documentation about it and I think it's not really used in the actual Django version (?). So any ideas/solutions are welcome and much appreciated! Thanks a lot...

• Any MVVM frameworks work well with NavigationWindows?

  - by Will

  I'd like to "throw away" the current version of a WPF application and move version 2 to a stable MVVM framework. The main concern I'm having is that I don't see much talk about MVVM frameworks and navigation (i.e., NavigationWindows and Frames). My current app relies heavily on Pages to present views to the user. I would prefer to keep it this way. I'd rather not change everything to UserControls and rely on DataTemplates to switch out the view I need to present. Are there any MVVM frameworks that: Work well with NavigationWindows and Pages Provide ViewModels adequate access to the navigation process Provide the ability to change navigation in response to security-related events (e.g., redirect to login Page after logout)

• Prevent OCUnit tests from running when compilation fails

  - by mhenry1384

  I'm using Xcode 3.2.2 and the built in OCUnit test stuff. One problem I'm running into is that every time I do a build my unit tests are run, even if the build failed. Let's say I make a syntax error in one of my tests. The test fails to compile and the last successful compilation of the unit tests are run. The same thing happens if one of the dependent targets fail to build - the tests are still run. Which is obviously not what I want. How can I prevent the tests from running if the build fails? If this is not possible then I'd rather have the tests never run automatically, is that possible? Sorry if this is obvious, I'm an Xcode noob. Should I be using a better unit testing framework?

• Popup Dialog Box Manager using PureMVC

  - by webwise

  I am developing a a game in Flash using the PureMVC framework. From time to time I need to show dialog pop-up window to get a user response back (e.g. "Cancel", "OK" and other kinds of asynchronous user feedback) while "locking" the background for interactivity. I need some management for my pop-ups: all pop-up notifications should be stacked up, so that if two (or more) pop-up messages are initiated at the same time I show them one by one. What's the best practice here? Should I employ a proxy to manage my pop-ups (sounds unreasonable). How do I get feedback back from my dialog? using notifications?

• WCF on Win Server 2008 and IIS7 with only net.tcp binding hide IIS features

  Hi all, I've installed HTTP Activation and Non-HTTP Activation IIS's features for Framework.NET 3.0 under WCF Activation feature. I'm trying to remove http and https bindings (under default Web Site) from IIS Manager and leave others (net.tcp, net.msmq, etc.) but if I close and re-open IIS manager I not found any icons in the right panel (Feature View). The only feature I see is IIS Manager Permissions. It's right I don't see them? I hope you can help me. Thank you in advance!
