  • Asynchronous Delegates Vs Thread/ThreadPool?

    - by claws
    Hello, I need to execute 3 parallel tasks and after completion of each task they should call the same function which prints out the results. I don't understand in .net why we have Asychronous calling (delegate.BeginInvoke() & delegate.EndInvoke()) as well as Thread class? I'm little confused which one to use when? Now in this particular case, what should I use Asychronous calling or Thread class? I'm using C#.

  • Are there any good books to learn C++ if you already know Java and C#

    - by JF LR
    Hi, I would like to know if you have any good books that teach C++ programming without repeating basic stuff. In fact, I already well know Java and C#. I also have a basic knowledge in C and assembly, so I understand a little bit pointer arithmetic, manual memory management and heap based allocation. I was looking at O'Reilly's C++ in a Nutshell and was also wondering if this book would be a good choice. Thank you

  • How can I tell what script a website uses or is built with? Could it be an 'off the shelf solution'

    - by ebs
    Hi. There is an excellent website that I would like to emulate some of the characteristics of in a website that I hope to develop. (I do not intend my site being in competition with them - mine would be more of a social networking site). Can anyone tell me if it is possible to detect which script and platform is being used on www.shoutlife.com? I have very little programming or website building experience so am considering using phpfox as my solution. Thanks in advance. EBS

  • Rails: Check output of path helper from console

    - by Thor Thurn
    Rails defines a bunch of magic with named routes that make helpers for your routes. Sometimes, especially with nested routes, it can get a little confusing to keep track of what URL you'll get for a given route helper method call. Is it possible to, using the Ruby console, see what link a given helper function will generate? For example, given a named helper like post_path(post) I want to see what URL is generated.

  • What .gitignore I should use with QT projects? (QT Creator)

    - by Envek
    So, after little thinking I have wrote the following: # In repository we don't need to have: # Compiled object files *.o # Generated MOC, resource and UI files moc_*.cpp qrc_*.cpp ui_*.h # Built windows .exe and linux binaries # NOTE: PROJECT is a your project's name, analog of PROJECT.exe in Linux *.exe *.dll PROJECT # Windows-specific files Thumbs.db desktop.ini # Editors temporary files *~ # Debug and Release directories (created under Windows, not Linux) Debug/ Release/ Please ask, what needs to be added or fixed (especially for Windows - I haven't one under hand now. And Mac too [haven't work in it at all]). I want to keep my repository clear :-)

  • What is the best approach for unit testing/integration testing GXT code?

    - by Arizonahockey
    I have been tasked to setup a continuous integration environment for a GXT 2.1.1 and GWT 2.0.1 environment. Unfortunately I am new to AJAX and Web Services and have little idea how to setup unit tests in the browser environment. Unit tests for the server backend I already have done, since I am a pro at that. GXT is not quite pure GWT which provides some unit testing structure. If anyone has a good starting point...

  • JQUERY, scrollTo, after scrolling down, the page won't let me scroll up for a second... Y?

    - by nobosh
    I'm using the following JQUERY to attach an even to a link in the header, which essentially scrolls to the bottom of the page: $('#comment-count-btn').click(function(){ $('html,body').scrollTo('#comment-wrapper', 500); }); Problem is, that it scrolls all the way to the bottom of the page (which is correct), but then when I try to scroll up a tad, the scroll bar jumps, as if it's locked for a little bit. Any ideas?

  • Why MyModel.all works in Rails ?

    - by AntonAL
    Hi, i don't understand this little thing: Suppose, we have "Person" model class Person < ActiveRecord::Base end Why Person.all works ? Person.all.each { |p| do_something } This syntax tells us, that we have Person class-object instanciated somewhere ? Or is it some convention over configuration case ?

I coded the above code in the little hous after a longer hacking run

  • Flex-Flash frontend for Wordpress

    - by user252160
    We all know what Wordpress can do with a little bit of css goodness. I was wondering whether the idea could be extended even further and make a completely separate Flash/Flex frontend for a website, that uses Wordpress in the back. That would certainly be possible. I was just wondering whether its practical. Any progress on the topic ?

  • Is there an easy way to stream a m3u in iPhone?

    - by marty
    I can have a UIWebView with the .m3u file opened, which will go to the webview with a play button displayed, and that automatically goes to the quicktime player and starts playing the stream. But when I press the done button, it goes back to the UIWebView with a little play button in the middle, and from there you can go back to the previous screen (it was selected from a tableview). So I just want it to automatically load the quicktime player in the view. How can I do that?

  • Tech necessary to build a live video chat site?

    - by tomeaton
    Hi, I'm looking to build a live video chat site. Before writing a project description, hiring a developer, etc., I'm doing a little research on what types of technologies / web development skills are necessary in order to build this type of site. The site will feature live video and audio for users to be able to chat with eachother, a simple profile which they can fill out, and the ability to filter the types of users they are connected with. Your feedback is appreciated. Thanks, Tom
