  • Hyperlinks and iPad videos

    - by bhan
    Hello everybody, I'm trying to develop something in the cloud incorporating video, text and images. However, any hyperlinked content that appears above or below the video is unclickable, as the video takes the focus on the iPad. This isn't a problem with Safari in general, as it works on Desktop Safari. Thankyou, BH

  • Creating a Virtual Webcam Device for OS X

    - by andsve
    I am looking for a solution to create a "virtual" webcam device under OS X (that acts just as a normal hardware webcam, but the application has full control over what to output). I'm fairly experienced with C++, but not so much with Objective-C and OSX/Cocoa programming. Anyone that can point me in the right direction, where to look and what I should be looking for? I've searched, but most of the results seems to focus on Windows and DirectX. Thanks!

  • Is it against best practice to throw Exception on most JUnit tests?

    - by Chris Knight
    Almost all of my JUnit tests are written with the following signature: public void testSomething() throws Exception My reasoning is that I can focus on what I'm testing rather than exception handling which JUnit appears to give me for free. But am I missing anything by doing this? Is it against best practice? Would I gain anything by explicitly catching specific exceptions in my test and then fail()'ing on them?

  • jQuery Validator's "required" not working when value is set at statup

    - by nandrew
    Hello, I have a problem with jQuery Validator. I want to use "required" property on a text input. It doesn't work when input has set value attribute by HTML code (tested on Firefox (3.5), and on IE 8 - on IE it works a bit better). Story: 1. Page loads; 2. value is cleared; 3. focus is changed. 4. Nothing happens but the error message should be displayed; 5. getting back to the field and typing some characters. 6. changing focus; 7. getting back to the field; 8. clearing the field. 9. Error is displayed even before leaving the field. The HTML code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <script src="Web/Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="Web/Scripts/jquery.validate.js" type="text/javascript"></script> </head> <body> <form id="form1"> <input type="text" id="name1" name="name1" value="test" /><br /> <input type="text" /> </form> <script type="text/javascript"> $(document).ready(function() { var validator = $("form").validate({ rules: { name1: { required: true, minlength: 2 } }, messages: { name1: "bad name" }, }); }); </script> </body> </html>

    - by Bill
    I have a GTK/C++ program that uses a ScrolledWindow. I keep adding data to the list within the scrolled window, and I want to keep focus on the newest item.

  • Container div ignores height of floated elements

    - by Thomas
    Ok, so this seems like a really silly problem but I can't get my container div to inherit the height of the floated elements inside of it. Since I need to center the container div, I can't use float to fix this problem. Here is my css: #container { margin: 0 auto; width: 1000px; border-left: 1px solid #f1f1f1; border-right: 1px solid #f1f1f1; border-bottom: 1px solid #f1f1f1; } #focus { padding-left: 23px; width: 977px; padding-top: 20px; padding-bottom: 23px; border-bottom: 1px solid #f1f1f1; float: left; } .rslider { float: left; width: 600px; margin-left: 15px; } .welcome { float: left; width: 300px; } Html: <div id="container"> <div id="logo_block"> <a href="#"><img src="img/logo.jpg" alt="" /></a> </div> <div id="focus"> <div class="welcome"> <h1>All About This Page</h1> <p>Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, liquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium.</p> </div> <div class="rslider"> <img src="img/slider_image.jpg"> </div> </div> </div> Any ideas?

  • What's the best way to mix Ruby and other languages? (Especially C++)

    - by Andy
    Hi, I'm learning Ruby, and I'm starting to play with building extensions in C. I have Programming Ruby The Pragmatic Programmers' Guide and so I can follow that for the basic nuts and bolts. What I was wondering is if there already existed some nifty frameworks/whatever to help interoperability between Ruby and other languages, with C++ being the most important for me. I've tried googling, but the results focus on language comparisons, rather than language interoperability. TIA, Andy

  • remove double http:// from input via jquery

    - by loo
    I have a textarea with a default value of http://. Now when an user pastes in an url (if they don't know what they are doing, like most people) it comes out like this http://http://www.google.com. I've seen a site that as soon as you have http://http:// it removes one via Ajax. I am not familiar with Ajax, so can anyone help me? I don't want to clear the field on focus only.

  • How can I securely check if a username is already taken?

    - by Geo
    I have a form where someone can create a new user. I'd like to add some AJAX to check if a username is taken, as soon as the input field loses focus. I'm not really sure how to go about this, as this could pave the way to bruteforce attack, since you could check for any username and see whether or not it exists. Any suggestions?

  • RequiredFieldValidator not working.

    - by ProfK
    With the following simple mark-up, I get very strange behaviour in FF and IE8. If I give the textbox focus, and tab out, nothing happens. If I give a user name value, and erase it immediately, nothing happens. However, only when I supply a user name, tab away, the erase it and tab away again, do I finally get a red star "required" mark. The summary doesn't show at all.

  • How late it is to not migrate to .Net 3.5 from .Net 2.0 ?

    - by this. __curious_geek
    We have some applications that are being worked upon in .Net 2.0 since long back. I'm recommending my team to move the base from .net 2.0 to .net 3.5sp1 and focus and leverage from C# 3.0 but I'm facing difficulties in doing so. What are the implications of not migrating to .net 3.5 and C# 3.0 ? What are your experiences on this front and what tactics did you use to successfully migrate your team and projects to .net3.5.

  • How to activate Mac OS X application with a given process ID?

    - by Olivier
    I know the process id of an application in Mac OS X. How can I switch to it (using applescript, or python, or whatever)? By "switch", I mean, put in focus. The usual solution is to use the applescript code tell application "Foo" activate, but here the name is not useful because I have many instances of the same application running. I am however able to get the process id of the application. How can I switch to this application programmatically?

  • Flash Camera Permissions Dialog: Why does it sometimes take more than one click to work?

    - by Emmett Shear
    Often, but not always, the first few clicks on the "Allow" button on the Flash camera permissions dialog are ignored. This is very frustrating for users. And for me, when I'm testing code! I'm afraid I don't really know what else to say about the problem to give more insight. My hunch is that it has something to do with getting focus on the embed element, but that is merely a guess. See Justin.tv for an example.
