  • Do WebSockets have exclusive access to their sockets?

    - by Aoriste
    I'm curious to know if, after a WebSocket has been established (after having received the proper handshake from a server that supports them), whether or not the TCP socket used by the "WebSocket connection" is used exclusively by the WebSocket, or if the browser may still make regular HTTP requests with it. It only makes sense to me that WebSockets would have exclusive use of their TCP sockets, but I don't remember having read in any of the documentation that such is the case.

  • why doesn't the jquery ui multiselect plugin refresh with ajax?

    - by oo
    i take a regular multiselect listbox and convert it to a jquery ui multiselect listbox by calling this: $(".multiSelectMe").multiselect(); As per the API, i call this method in the return of an ajax function $(".multiSelectMe").multiselect("select", "Item 1"); but nothing seems to happen. i can't figure out a way to have this programatically add items within an ajax call. i was thinking there was maybe another "refresh" method or something like that but i can't find any.

  • What is NetFx in the Windows SDK?

    - by emddudley
    What is NetFx, in the context of the Windows SDK? What differentiates NetFx tools from the tools in the regular SDK bin directory? I noticed that the version of sgen.exe in C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\ was built against .NET 2.0, but the version in C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\ was built against .NET 4.0.

  • Show form that showDialog from mainForm won't block it, but closing mainForm will close it

    - by meme
    how yo show a form which needs to run synchronously. I tried running application.run from a queueworker of a threadpool- but I had some invalid handles sometime. tried using a regular thread but then when main form closes it doesn't close this- and I don't really like the idea of killing the thread on_formclosing. if I use form.show it's fine besides that fact that any showdialog from the main form will block also this. What's the best way to handle this?

  • JSF - get managed bean by name

    - by Konrad Garus
    I'm trying to write a custom servlet (for AJAX/JSON) in which I would like to reference my @ManagedBeans by name. I'm hoping to map: http://host/app/myBean/myProperty to: @ManagedBean(name="myBean") public class MyBean { public String getMyProperty(); } Is it possible to load a bean by name from a regular servlet? Is there a JSF servlet or helper I could use for it? I seem to be spoilt by Spring in which all this is too obvious.

  • What is the easiest x86 Embedded Linux?

    - by QAH
    I want to play around with some embedded linux. I want it to be able to run on an x86 processor (for start, it will be running on my regular PC). I have looked online, but the ones I have found seem hard to setup or lack proper documentation. So what are some good embedded x86 compatible linux distros that are easy to setup or have good documentation on how to get things setup?

  • Javascript Noob: How to emulate slideshow on front page by automatically cycling through existing ho

    - by Zildjoms
    hey everyone. hope you could help me out am working on this website and i've finished all the hover effects i like - they're exactly how i want them to be: http://s5ent.brinkster.net/beta3.asp - try hovering over the four links and you'll see a very simple fade effect at work, which degrades into a regular css hover without javascript. what i plan to do is to make the page look like it had a fancy slideshow going on upon loading and while idle, and i wanted to achieve that by capitalizing on the existing hover styling/behavior of the main page links instead of using another script to create the effect from scratch. to do this i imagined i'll need a script that emulates a hover action on each link at regular time intervals once the page has loaded, starting from left to right (footcare, lawn & equipment, about us, contact us), looping through all 4 links indefinitely (footcare, lawn & equipment, about us, contact us, footcare, lawn& equipment, etc.) but pauses when any of them have been actually hovered over by a viewer and resumes from wherever the user left off upon mouseout. hope you get my drift... i also want to achieve this without unnecessarily disrupting the current html. so i guess everything will have to be done by scripting as much as possible.. i'm very new to javascript and jquery. as you can see at s5ent.brinkster.net/beta3.1-autohover.asp, the following script i made works wrong: it hovers-on all of them at the same time and doesn't hover-out anymore. when you try to actually hover into and out of each link the link just comes back on: <script type="text/javascript"> $(document).ready(function () { var speed = 5000; var run = setInterval('rotate()', speed); }); function rotate() { $('.lilevel1 a').each(function(i) { $(this).mouseover(); }); } </script> it's just gross. aside from the fact that this last bit of script isn't even working in ie. could you please help me make this thing happen? that'd be really sweet, guys. i know there are tonsa geniuses out there who could whip this up in no time. or if you have a better way to go about it by all means kindly lemme know. thanks guys, hope you're all havin a blast.

  • Programatically Dial a Phone number and pass DTMF using the iPhone SDK

    - by L. DPenha
    How do you programatically do the following from the iPhone SDK 1) Programatically Dial a Phone Number through the iPhone SDK 2) Bypass the dial / cancel prompt that the iPhone brings up 3) Send additional DTMF after the number is dialed just like how you would program pauses into a regular phone. I know you can make a tel:// call but the issue is that it brings up the dial / cancel prompt and after that it prevents any future DTMF from being sent.

  • HttpUtility.UrlEncode in Windows Phone 7?

    - by lfoust
    The regular .Net framework contains HttpUtility.UrlEncode in the System.Web Assembly and in Silverlight it appears it was moved to System.Windows.Browser. But in Windows Phone 7 (which I thought was the same as Silverlight) I can't seem to find a proper way to UrlEncode anything. Neither of the previously mentioned assemblies are available in the Windows Phone 7 environment.

  • Java properties - .properties files vs xml?

    - by pg-robban
    I'm a newbie when it comes to properties, and I read that XML is the preferred way to store these. I noticed however, that writing a regular .properties file in the style of foo=bar fu=baz also works. This would mean a lot less typing (and maybe easier to read and more efficient as well). So what are the benefits of using an XML file?

  • Is there a simple way for opening one (or many) opengl window in mac OS X with C++ ?

    - by Petruza
    Yes, I hate Objective-c, plus my project will be portable, so I'd like to code as much of it in C++ as possible, ideally 100%. So I have a regular C++ project made with Xcode, and want to open some OpenGL windows. edit: Damn, Glut takes over the app's control with glutMainLoop(), pretty much as SDL does, I'm trying to break free from that schemes. Will try freeglut, although I can't find OSX binaries, and I always have such bad luck trying to compile someone else's code.

  • A good web data extraction/screen scraper program?

    - by Taylor
    I need to capture product data from a site on a regular basis and wondered if any one knows of a good software program? I've trialed Mozenda but its a monthly subscription and pricey in the long term. Obviously something thats free would be best but I don't mind paying either. Just need a decent program thats reliable and doesn't require much programming knowledge.

  • Very simple regex not working

    - by Thomas Wanner
    I have read that to match a word inside of a string using Regular expressions (in .NET), I can use the word boundary specifier (\b) within the regex. However, none of these calls result in any matches Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", "\b@p1\b"); Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", "\bINSERT\b"); Is there anything I am doing wrong ?

  • Can a Winforms/WPF app act as HTTP server?

    - by user46703
    Hi, I have a desktop written with Winforms. Now I have requests that people want to access the data from other machines. First I thought about a regular Client/Server app but now I think best would be if the app could act as HTTP server and send HTML to connected browsers. Does anybody know if there is a library available to add HTTP server functionality to an app? Ideally it would be able to serve ASP.NET content.

  • Regex split into overlapping strings

    - by polygenelubricants
    I'm exploring the power of regular expressions, so I'm just wondering if something like this is possible: public class StringSplit { public static void main(String args[]) { System.out.println( java.util.Arrays.deepToString( "12345".split(INSERT_REGEX_HERE) ) ); // prints "[12, 23, 34, 45]" } } If possible, then simply provide the regex (and preemptively some explanation on how it works). If it's only possible in some regex flavors other than Java, then feel free to provide those as well. If it's not possible, then please explain why.

  • jQuery - $.each loop through json code

    - by Ice
    Due to the way my serverside script outputs I receive multiple JSON objects. {jsonhere}{jsonhere1}{jsonhere2}{jsonhere3} etc.. They aren't seperated by anything. If I would do a split based }{ I would lose those brackets. So is there an outerloop I can put over the regular $.each loop to make this work? Thank you, Ice

  • Find and replace in a block of text.

    - by David Tildon
    I have a database full of text fields that look like this: (paragraph of normal text) image:blog/clownboy.jpg (another paragraph) I'm trying to write a view helper for Rails that will take one of these big blocks of text, find bits like "image:blog/clownboy.jpg" and replace them with the corresponding <img src="blog/clownboy.jpg"> (without disturbing the surrounding whitespace) before outputting it to the user. I've been trying for an hour or so now, but I'm new to Ruby and the regular expressions are still a bit beyond me.
