  • Support for multiple domains/subdomains in Rails

    - by thefactor
    I have a Rails app that has a similar setup to Tumblr, that is, you can have either: (1) Subdomain hosting (your-username.myapp.com) (2) Domain hosting (your-username.com) Both would forward to a personalized website for that user, created with my application. How can I accomplish this in Rails? I have been able to get (1) working with subdomain-fu, but I'm not sure how to get (2) working. Any pointers (plugins, gems, tutorials), etc. would be greatly helpful, I can't seem to find any. Thanks!

    - by Ian
    Hi All, I am setting up a Continuous Integration server. I have one issue that doesn't seem to be mentioned in the tutorials. I have a ASP.net Web Application that I need to compile and them publish. My Problem is that I seem to be able to compile the app but when I attempt to use a buildPublisher this copies every thing including .svn files & folders and ms CS files. I am using an MSBuild task to compile my source. I tried setting my MSBuild Output Directory to directory but this didn't seem to have any effect. What am I not understanding? Thanks

  • ASP MVC Creating Form Rows Dynamically

    - by Jonathan Stowell
    Hi Guys, I haven't even attempted this yet and am creating this question for advice really. I have a strongly typed page which receives a form model composed of several components. It is to create a mitigating circumstance (MC) for a student at a university for my final year project. A MC can be composed of the initial problem, assessment extensions, and I use a multi select box to allow the user to select staff retrieved from the database which are able to view the MC once created. The thing is I feel that a student could be granted many assignment extensions for one problem. I am wander if it is possible to include a button/image on the form which when clicked will create a new assessment extension object, and duplicate the form components to set the values for the object? This would all need to occur without any page refreshes. Any advice, or links to good tutorials would be appreciated. I have so far been unable to find any suitable examples. Thanks, Jon

  • subversioning ipad app project

    - by MistakesRInevitable
    Hi All, I am currently looking at setting up an Ipad app project into subversion. Ive had a lot of experience with windows based development and .net. With this we have just created a repository in a network folder (by just right clicking - TortiseSVN - create repository) , than all we have done is our developers have checked out from this directory. How do we go about doing this in xcode. I know subversion is integrated with xcode and I am pretty confident of doing everything (from tutorials) except for the creation of the repository. Just wondering how we go about creating a repository in a folder based up on network folder? Thanks in advance

  • How to start an android project with downloaded sample code

    - by yokyo
    Hi, I'm pretty new to android, and just finished setup my environment and reading some tutorials. Then I got sdk samples from the web. Okay, what I wanna ask you is that is there a way to start a sample as a project in the Eclipse? I mean like clicking a project file in c# or a solution file. Here is my folder which I unzipped the code, \android-sdk-windows\samples\android-8\NotePad There are three folders and one file in the folder, \res, \src, \tests, and AndroidManifest.xml Or, do I need to make a new android project and import (or add files? maybe) them? Thanks in advance, yokyo

  • Capturing Mac OS X System Audio output with Python

    - by richbs
    Hello, I've been trying to "hijack" the Mac OS X system audio using PyAudio and save to a wav in python. That is, I do not want to record from an input device such as a microphone. I want to grab the sound output from any or all applications. I have followed the tutorials on the PyAudio site but these do not appear to cover my use case and when I try to read from the output stream I unsurprisingly get the paCanNotReadFromAnOutputOnlyStream exception. Fair enough! Is there a way to do what I am proposing with the PyAudio or other FOSS Python Library?

  • recommend a server side technology for gwt (beginner)

    - by user486503
    hi all ! I am developing a gwt project and am looking for an appropriate server side technology. it should support be open source and support user login (and not using openID...) with password recovery etc it seems that the de-facto standard would be spring + hibernate. however, I am unfamiliar with neither of them and understand that the learning curve (especially for spring) is very high. gwt was quite easy to learn using GOOG's excellent online tutorials but the spring equivalent seem to impose lots of configuration files and deeper understanding of its internals. so I am looking for a simpler server side technology to deploy my gwt app. I am definitely prepared to learn a new framework if necessary but not something that would take me 2 months just to understand the fundamentals... any ideas...?

  • How to deploy VS2008 express desktop project?

    - by melaos
    hi guys, i was wondering how could i deploy/make it into an installer for an app which is created using vs 2008 express. i know that the setup and deployment feature is only available via the full version of visual studio right? So are there any add ons or perhaps additional free/or non-free if it has to come to that which i can use to do this? or is the best tool for the job is the old visual studio installer from the vs 6.0 days? :) thanks Updates: After some googling, i found this link on using click once to deploy vs 2008 express with tutorials in them, i'll check it out, but of course more & better recommendation is always welcomed :)

  • Actionscript / Flex: a question about handleAllEvents() method.

    - by Patrick
    Hi, in Adobe tutorials, they suggest to create a class to handle the events (see below the copy/pasted code, and link to page). I was wondering if I have to handle all events with the function handleAllEvents, using if statements to check if the target is the one I want, and the event is the one I want. i.e. if (event.type=="click") && (event.currentTarget == "myId") Should I have a list of ifs (for each target and each event type ?) thanks // events/MyStaticEventHandler.as package { // Empty package. import flash.events.Event; import mx.controls.Alert; public class MyStaticEventHandler { public function MyStaticEventHandler() { // Empty constructor. } public static function handleAllEvents(event:Event):void { Alert.show("Some event happened."); } } } Link (at the bottom): http://livedocs.adobe.com/flex/3/html/help.html?content=events_05.html

  • How do you display a PHPmyadmin table onto a web browser/web page?

    - by user1390754
    Just a simple question, i've been searching around and for some reason i cannot find an answer to this. after creating a database/table in Phpmyadmin using xampp, what command do i need to put into my webpage (PHP) to show the table I made? I know the first step involves connecting to the database and i think i've done that properly. This is the code i found from somewhere about connecting (w3 tutorials I believe) $con = mysql_connect("localhost","xxxxxx,""); if (!$con) { die('Could not connect: ' . mysql_error()); }

  • What happens if an asynchronous delegate call never returns?

    - by RichardHowells
    I found a decent looking example of how to call a delegate asynchronously with a timeout... http://www.eggheadcafe.com/tutorials/aspnet/847c94bf-4b8d-4a66-9ae5-5b61f049019f/basics-make-any-method-c.aspx. In summary it uses WaitOne with a timeout to determine if the call does not return before the timeout expires. I also know that you should have an EndInvoke to match each BeginInvoke. So what happens if the wait timeout expires? We (presumably) DON'T want to call EndInvoke as that will block. The code can go on to do 'other things', but have we leaked anything? Is there some poor thread someplace blocked waiting for a return that's never going to happen? Have we leaked some memory where the result-that-will-never-return was going to be placed?

  • How should I mock out my data connectivity

    - by BobTheBuilder
    I'm trying to unit test my Data Access Layer and I'm in the process of trying to mock my data connectivity to unit test my DAL and I'm coming unstuck trying to mock out the creation of the commands. I thought about using a queue of IDbParameters for the creation of the parameters, but the unit tests then require that the parameters are configured in the right order. I'm using MOQ and having looked around for some documentation to walk me through this, I'm finding lots of recommendation not to do this, but to write a wrapper for the connection, but it's my contention that my DAL is supposed to be the wrapper for my database and I don't feel I should be writing wrappers... if I do, how do I unit test the connectivity to the database for my wrapper? By writing another wrapper? It seems like it's turtles all the way down. So does anyone have any recommendations or tutorials regarding this particular area of unit testing/mocking?

  • How to set ItemsSource?

    - by Mark
    This dialog makes no sense to me And I'm having trouble finding good tutorials on it. Most of the examples aren't detailed enough, or do stuff via code, but I'd like to take advantage of the IDE as much as possible. Whats the difference between ItemsSource and DataContext? I'd like to bind it to just a List for starters. I don't need SQL or databases or anything fancy. Where would I declare my list? In MainWindow.xaml.cs? How do I get it to appear in that dialog?

  • Making commercial Java software

    - by roddik
    Hi. I intend to make some software to be sold over internet. I've only created open-source before, so I have really no idea of how to protect it from being cracked and distributed as warez. Bearing in mind that I know like two programms that aren't either cracked or not really useful I decided that the only more or less reliable way may look like this: Connect to a server and provide licensing info and some sort of hardware summary info If everything is fine, the server returns some crucial missing parts of the program bound to that certain pc along with the usage limit of say 2 days That crucial stuff is not saved to hard drive, so it is downloaded every time the program starts, if the programm runs more than 2 days, data is downloaded again If the same info is used from different computers, suspend the customer account What do you think about this? It may seem a bit to restrictive, but I'd better make less sales at first then eventually see my precious killer app downloaded for free. Anyways, first I need some basic theory/tutorials/guides about how to ensure that user only uses a certain Java app if he has paid for it, so please suggest some. Thanks

  • Running a python script for a user-specified amount of time?

    - by Rob
    Sorry, this is probably a terrible question. I've JUST started learning python today. I've been reading a Byte of Python. Right now I have a project for Python that involves time. I can't find anything relating to time in Byte of Python, so I'll ask you: How can I run a block for a user specified amount of time and then break? For example (in some pseudo-code): time = int(raw_input('Enter the amount of seconds you want to run this: ')) while there is still time left: #run this block or even better: import sys time = sys.argv[1] while there is still time left: #run this block Thanks for any help. Also, additional online guides and tutorials would be much appreciated. I really like Byte of Python. Dive into Python can't quite hold my attention, though. I suppose I should suck it up and try harder to read that one.

  • Client-server application between two computers in the same network (using boost::asio)

    - by Edwin
    I'm trying to set up a basic communication between my desktop PC and my laptop (latter one using wireless connection) both being in the same network, using the boost::asio tutorials: synchronous client and synchronous server (in c++). When I run both the server and client on the same machine (using the localhost and the datetime port as parameters), it works splendidly. But if I try to set up the laptop as server (tested it with netstat -anb from the command prompt, it is indeed running and listening to port 13 as it's supposed to, and I even deactivated the firewall to make sure it doesn't cause any problems), I cannot connect to it with the client (set up on the PC), no matter what IP I tried (localhost, and basically any IPs that ipconfig -all gave me). So no matter what I tried, I cannot find the correct address that which the client can use to connect to the server. Could anyone help me please?

  • How can I learn Android?

    - by Daisama
    I am a freshman in college which has been Java programming for over a year. I haven taken a couple of programming courses, both of which were with Java. And I have done web development for several years. So overall, I would't say that I am a complete beginner in programming. Recently, I have developed a strong interest in developing for Android. I read that Android development was with Java and I thought it would making development easier for me. But I was very wrong. Based on reviews from Amazon, I have begun reading "Professional Android Application Development by Meier but everything is going over my head. The Busy Coder's Guide to Android Development seems a bit more for my level but I still want everybody else's opinion. The Google stuff isn't very helpful to me at my level and neither are the tutorials on anddev and such. Any advice for a complete beginner on how to get started? Thanks.

  • Writing different structs to a file in C++? [on hold]

    - by user58053
    I need a way to write structures of three different kinds to a binary file, which later has to be searched. (As in, for example, struct A has two fields, an int and a char; struct B has int and a long; I need to output all structures whose int equals the one given from keyboard). I understand how to write structs of the same kind to a file and how to search them, but here I am just lost, best thing I came up with is declaring a struct containing all possibly needed fields and leaving the ones I don't need empty, but it really feels wrong, there HAS to be a better way to do that. I've read about binary files and could not find anything relevant, most examples and tutorials deal with writing one data type. Could anyone point me in the right direction? EDIT: I am looking for what @Jerry_coffin called database mode, and will probably use one of the existing database systems for that, best way to go, probably. Thank you everybody for the suggestions

  • View like android's contact screen

    - by Maragues
    I am developing an application with a large number of elements that must be ordered alphabetically, and I'd like it to have the same look and feel as android's contact list, That is [Letter] <contact> <contact> [Letter] <contact> <contact> <contact> etc. Which is the best way to achieve this same layout? I've seen several tutorials concerning scrollable lists, but this is a bit different. I've looked a bit through android's source code, but if anyone has the answer, it would save me a lot of time. Thanks in advance.
