  - by ragupathi

  I have been using rails for developing web applications and now i need to do design an api for iphone application and since i used respond to json it also produces json but i use devise for authentication in my web application and when i send email and password along with the api it gives out {"user":{"authentication_token":"Lsusyd27ewgasga63","email":"[email protected]"}} and there is forgot password functionality in the iphone app but in the web application when clicking on forgot password button it sends an email to the users email, whereby the user has to go to his mail and click on the link sent and it will take to the change password path and after changing it the user will be login but in this iphone app i want to send the password to the user mail and the user can use that password and login. How can i do this? Also do i have to create new controllers for api or the web application controller is enough if it respond as json? please help me.

• Trouble using SFML with GCC and OS X

  - by user1322654

  I've been trying to get SFML working for a while now and I've been trying to get it working using GCC. I'm on OS X by the way. I followed the standard Linux instructions and using the Linux 64-bit download however when it comes to compiling... g++ -o testing main.cpp -lsfml-system This happens: main.cpp: In function ‘int main()’: main.cpp:7: error: ‘class sf::Clock’ has no member named ‘GetElapsedTime’ main.cpp:9: error: ‘class sf::Clock’ has no member named ‘GetElapsedTime’ main.cpp:10: error: ‘Sleep’ is not a member of ‘sf’ So I thought it could be due to not using includes, so I changed my gcc compile command to: g++ -o testing main.cpp -I ~/SFML-1.6/include/ -lsfml-system and now I'm getting this error: ld: warning: ignoring file /usr/local/lib/libsfml-system.so, file was built for unsupported file format which is not the architecture being linked (x86_64) Undefined symbols for architecture x86_64: "sf::Clock::Clock()", referenced from: _main in ccZEiB7b.o "sf::Clock::GetElapsedTime() const", referenced from: _main in ccZEiB7b.o "sf::Sleep(float)", referenced from: _main in ccZEiB7b.o ld: symbol(s) not found for architecture x86_64 collect2: ld returned 1 exit status** And I have no idea what to do to fix it.

  I posted this question early yesterday, but the thread seems to have died out. For reference, see http://stackoverflow.com/questions/2619117/git-push-origin-master . Here's the low-down: I'm new to git. I just set up an account with github and I followed all their instructions flawlessly until I got to the last command of git push origin master Upon entering this command, I get the error message "fatal: No path specified. See 'man git-pull' for valid url syntax." If I type in git origin show the output I see is origin. If I type in git remote -n show the output is * remote origin URL: [email protected]: HEAD branch: (not queried) Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) Please help me get to the bottom of this.

• Website settings for running visual web as root?

  - by Curtis White

  Scott Gu explains how to run visual web developer using a root path, here: http://weblogs.asp.net/scottgu/archive/2006/12/19/tip-trick-how-to-run-a-root-site-with-the-local-web-server-using-vs-2005-sp1.aspx This worked exactly as he described in one instance for me. But, today I do not see this option. More over, I do not think I have a solution file, and I think that has something to do with it. I'm aware there are web application projects and web site model, and web site model is basically just a "directory". But can web site model, also, have a solution file for this setting or not a solution file? What determines that? I am interested in using this method on on a web site, i.e directory only model.

• Editing and iPhone SDK Framework ?

  - by Chris

  I am working with MapKit and want to be able to add a (NSString *)itemTag value to each of my annotations. I have created myAnnotiation.m and myAnnotation.h I tried adding itemTag to the myAnnotation.h/m but when I try to access currentAnnotation.itemTag within my main code, it says "itemID not found in protocols" - so I went to the MapKit.Framework and into MKAnnotation.h. I added (NSString *)itemID, but when I save the .h file in the Framework, it changes the file's icon and doesn't appear to by jiving with everything else. Any help or links to help would be greatly appreciated. I am not even sure if I'm on the right path here, but Googling "modify iphone sdk framework" does not turn up much.

• If you have an application localized in pt-br and pt-pt, what language you should choose if the syst

  - by Sorin Sbarnea

  If you have an application localized in pt-br and pt-pt, what language you should choose if the system is reporting only pt code (generic Portuguese)? This question is independent of the nature of the application, desktop, mobile or browser based. Let's assume you are not able to get region information from another source and you have to choose one language as the default one. The question does apply as well for more case including: * pt-pt and pt-br * en-us and en-gb * fr-fr and fr-CA * zh-cn, zh-tw, .... - in fact in this case I know that zh can be used as predominant language for Simplified Chinese where full code is zh-hans. For zh-tw, zh-hant-tw, zh-hk, zh-mo the proper code (canonical) should be zh-hant. In fact the question can be extended to: How to I determine the predominant languages for a specified meta-language? I need a solution that will include at least Portuguese, English and French.

• Can I use android.os.* libraries in a standalone project?

  - by medicdave

  I'm trying to develop an external library (not sure if that's the right term) to provide prepackaged functionality in Android projects. Working in Eclipse, I've added the appropriate android.jar file to the build path, and everything is happy both while editing and upon compilation. However, when I use Android's Handler and Message classes (android.os.Handler, android.os.Message) for inter-thread communication, I get exceptions unless I'm running within an Android app, on the emulator or a device. I can no longer test my library in a "standalone" way without having to go through a running Android target. Is there any way for me to include these two Android classes and still be able to test my library standalone? Do I need to have the Android source available? Or would it require some sort of conditional compilation hand-waving?

• 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?

• How do I use a shared library (in this case JsonCpp) in my C++ program on Linux?

  - by Not Joe Bloggs

  I'm a new-ish C++ programmer, and I'm doing my first program on my own using C++. I decided I would like to use JSON to store some of the data I'm going to be using, and I've found a library to handle JSON, JsonCpp. I've installed the library using my Linux system's package manager, and in my C++ code, I've used in my source code file #include <json> and compiled it using g++ and it's -ljson and -L/usr/lib options (libjson.so is located in /usr/lib). However, the first usage of Json::Value, an object provided by the library, gives a compilation error of "Json has not declared". I'm sure my mistake is something simple, so could someone explain what I'm doing wrong? None of the books I had mention how to use shared libraries, so I've had to google to find this much.

• is it possible to do partial postback on web?

  - by carter-boater

  Hi all, I read some paragraphs in a book saying that it is not possible to do a partial postback for web, even AJAX is employed. Ajax will postback everything and update only ajaxfied controls. However, on pages I made using ajax, I used Fiddler to monitor the transportation. I found when the page initial load, it loaded everything include pictures .... However, when I click a button and do a ajax postback. I can only see the some data were loaded.... Looks like it doesn't need to reload the whole page again. I don't know if what I see is correct? Or the book I read is correct? Thank you guys.

• Reinstall TeamCity when Tomcat becomes corrupt

  - by dodegaard

  I've got a TeamCity 4 installation where tomcat has bit the dust with the following error "The APR Based Apache Tomcat Native library which allows for optimal performance in production environments was not found in java.library path". It appears this started happening once the JDK was installed on the server to allow for a compile. The JDK has been removed and the JRE reinstalled but still no go. My question is should I reinstall TeamCity completely or is there a way to simply reinstall tomcat so I don't hose the configuration? Your help is greatly appreciated.

• How entity edit URL from within plug-in in MS Dyanmics CRM 4.0

  - by Greg McGuffey

  I would like to have a workflow create a task, then email the assigned user that they have a new task and include a link to the newly created task in the body of the email. I have client side code that will correctly create the edit URL, using the entities GUID and stores it in a custom attribute. However, when the task is created from within a workflow, the client script isn't run. So, I think a plug-in should work, but I can't figure out how to determine the URL of the CRM installation. I'm authoring this in a test environment and definitely don't want to have to change things when I move to production. I'm sure I could use a config file, but seems like the plug-in should be able to figure this out at runtime. Anyone have any ideas how to access the URL of the crm service from within a plug-in? Any other ideas? Thanks!

• fastest in-memory cache for XslCompiledTransform

  - by rudnev

  I have a set of xslt stylesheet files. I need to produce the fastest performance of XslConpiledTransform, so i want to make in-memory representation of these stylesheets. I can load them to in-memory collection as IXpathNavigable on application start, and then load each IXPAthNavigable into singleton XslCompiledTransform on each request. But this works only for styleshhets without xsl:import or xsl:include. (Xsl:import is only for files). also i can load into cache many instances of XSLCompiledTransform for each template. Is it reasonable? Are there other ways? What is the best? what are another tips for improving performance MS Xslt processor?

• Ruby on Rails form_remote_tag missing template

  - by Donald Hughes

  I'm using form_remote_tag(:url => {:controller => "home", :action => "search"}, :update => "mydiv"). When I click submit on the form "mydiv" is populated with the error "Template is missing. Missing template home/search.erb in view path app/views". I've tried multiple render options in def search, but they all result in the same error. It looks like the search method is trying to use it's default render even though I'm specifying what I want. I've tried: render 'index' render :text => 'Return this from my method!' Is my url incorrect? Is it not submitting back to my home controller's search method?

• How can I determine file encodings on Windows / IIS ?

  - by Dylan Beattie

  From the answers to this question it appears there's a file somewhere on our server that's been saved with the wrong encoding. I've seen this happen before - most often when pasting from Word into Visual Studio, when "smart quotes" can interfere with Visual Studio's encoding settings when saving the file. Thing is - the problem I'm having involves 20-30 different script files, include files and so on (hey, that was how we kept it modular back in the day...) and I really don't want to open every one of them in Visual Studio and check the file encodings individually. Is there any way I can analyze a folder tree full of files and spit out a list of each filename along with the text encoding used to save the file? (Or - if encodings aren't clearly specified - work out what encoding Microsoft IIS thinks was used to save the file?)

• Visual Studio 2010 Publish Web feature not including all DLLs

  - by manu08

  I have an ASP.NET MVC 2 application. Web project contains a reference to SomeProject SomeProject contains references to ExternalAssembly1 and ExternalAssembly2. SomeProject explicitly calls into ExternalAssembly1, but NOT ExternalAssembly2. ExternalAssembly1 calls into ExternalAssembly2 When I perform a local build everything is cool. All DLLs are included in the bin\debug folder. The problem is that when I use the Publish Web command in Visual Studio 2010, it deploys everything except ExternalAssembly2. It appears to ignore assemblies that aren't directly used (remember, ExternalAssembly2 is only used by ExternalAssembly1). Is there any way I can tell Visual Studio 2010 to include ExternalAssembly2?

• Invalid ADTS sampling_frequency_index and channel_configuration why?

  - by Moto

  Hello all, I hope someone can direct me on the right path before I put a lot of time and effort on this. I'm currently trying to parse an AAC+ frame to get information such as number of channels and sample frequency. So it seems that we can simply get this information from the ADTS header but most of the time this information is inaccurate. So the question is: -Why is this data inaccurate? What is the meaning of the ADTS header channel and sample freq? Should I rely on it? -Should I parse further down the frame to get this information? FYI, the AAC+ raw data is coming from streaming servers... Thanks for the help! -Moto
