I'm doing a training class right now and one of the games I plan on doing is a Jeopardy style of Q & A. The problem I'm trying to figure out is the buzzer. My idea is to use the projector as the question board I control. The trainees would go to an HTML page with nothing more than a single button. They would turn their monitors around to face me up front. As soon as I read the question they would click the button and it would change their screens the color red.
The button and background color change is easy enough, I got that. There are two problems I'm facing: 1) I need it so that they can't click the button until I'm done reading the question - this one isn't as important, I can just make up a rule. 2) Only the fastest person will have a red screen. To show me who clicked first. The others' buttons will be disabled.
I just have no idea how to even Google these two things. Like: "Disable button for other users"...? Or maybe, "only one click"...?
Any direction to search is appreciated. Eventually, I'd like to add other aspects to like the presenter could click an "incorrect button" then it would clear the screen and enable all the buttons again, for the answer steal.
You can do it with modern WebSocket or applications interact via TCP. However, WebSocket may be overkill for the simple application with a few teams. I faced the same problem before and developed a simple solution with PHP using Flock to write into a shared file on disk. Only request from one team gets the chance to write into that file. Stick to not to use WebSocket, the web page on client site does some polling to receive the "restart" signal from the server for the new question/round. It can run in LAN, different team gets different site, i.e. http://[server-ip]/team1, http://[server-ip]/team2.
You can have control over the round: allow them to press button/ restart, start a new question in http://[server-ip]/admin.
Further improvement can be made in several ways to facilitate your needs (i.e. assign team name, register team, use database instead of a flock file). The code is available here : https://github.com/minhhn2910/buzzergameshow

Sorry for cumbersome title, couldn't come up with more descriptive one.
The problem is when opened tab is left without user activity, for example user switched to another screen, Chrome stops rendering changes on that tab. Looks like any background activity is put on hold which is great from perspective of saving power and resources. But if user still needs to see all live updates what is the way to prevent tab to go to 'idle' state despite of having no user activity?
I was looking into chrome.idle API but it doesn't say how to prevent, only how to check.
It's relatively straightforward to detect some button presses on the tvOS Siri Remote: the pause/play button, the touchpad area, and with marginally more effort, the MENU button. But there seems to be no way detect or override the function of the + and - buttons, or the Siri or home buttons.
Or is there?
Currently the + and - (volume) buttons on the Siri remote are accessed through private functions. These can't be overwritten or detected, as they have a reserved function. The same goes for the home button.
There are a couple of points that support this claim. First, as the OP noted, there are no events that detect any actions related to the volume buttons. They don't trigger the pressesBegan or similar events either.
Another good place to look for more options with the remote/controller is GCGameController. It looks like it has functionality related to all, but the volume buttons, which are reserved. Take a look at the
Using the Apple TV Remote as a Game Controller section here. It mentions all of the buttons on the remote that can be used in a CGGameController.
As I mention in my other posts, this is a fairly new OS and not everything is available yet. You can always file a bug report with Apple and request certain API to be made public.
I am trying to figure out a way to create links to point to help files in my application based off the text on the screen.
Lets say my application reports the status of a car if it is running or not. If it is running everything is ok, but if it is not running it will display a reason such as:
In Park
Door is open.
Shut off.
Flat tire
When it displays the reason on the main page I want it to have a link pointing to the help file which will include a resolution to get the car back up and running.
The problem I am having is the the reasons change on the fly and update in real time. The resolutions for the problems are all different.
To give some background, the application is asp.net web application. I tried searching the web and I tried linking it to a simple page which had the links to the correct pages but that requires more user involvement. I want it to be click the problem and bring it right to the page.
Any information or suggestions would be great.
Thanks
OK. So first, I will try my best to explain so good. My friend has gotten cursed out on this forum for not explaining, so I will explain. :)
Ok so I have my program built and all. But then it hit me! Wouldn't it be better to add a news feature? One teeny tiny problem? I cant? How would I implement a interactive code into an HTML page.
Like can i connect a button to a URL that will make the program do something. Almost like you can open cydia tweaks with there identifier and url EXAMPLE: http://handleopenurl.com/scheme/cydia And then i can add urls so i can update the program, without updating the files.
Or even just a featured news thing would be nice. But how would i implement this perfectly. I tryed a webrowser, but the page is too big for it. I am good at html, not much at css, i mostly use Adobe Muse http://www.adobe.com/Muse
Last question. Kinda defies the first thing i said about having my program finished.
Is there a way i can add a plus button and make it add more buttons and more labels and all?
This would help with allowing users to customize more then what the program can handle. By The Way, its a winter board Theme Maker. So I have a bunch of icons with there bundle identifiers and I create the folders with VB.net and all that stuff. But i want users to be able to click a plus button to add MORE text boxes and file browsers.
Any ideas? Maybe DIM 1 as NewFileBrowser? But i need to move all the buttons and i need it to be able to be clicked an infinity amount of times. I can do the coding for all of these buttons, but i jest need to know how to create them <1 Move them and the button so that the button goes further down each time, and more boxes will go further down. Much help apreciated. THANKS:)
EDIT:
Are you trying to say that you're wondering how to have a web browser control in a vb.net >app, which displays a web page, and when a button is clicked on the page, your app detects >it and does something? – Thraka
That sums up the top part. I am using windows forms, and it is coded in VB.net
If you get the object you want, like the button, you can hook the event and have it call code in your form.
Find the object using the Browser.Document.GetElementById method.
With that object, add an event handler to the Click event.
See http://msdn.microsoft.com/en-us/library/system.windows.forms.htmlelementeventhandler(v=vs.110).aspx for information about the event handler used
I've run into this problem twice in all the site's I've designed and I can't figure out how to fix it. (The flash compiler has not given me any errors for this.)
Here is the link first of all

Once you're in the site click on portfolio and then click on "the excelsior" what happens is that for the first 4-5 clicks it won't do what it's supposed to do and it'll start randomly either stopping at a frame or playing a from a frame. Once it's done it's randomness it all works perfect again, but those initial clicks do not take you anywhere.
This is an externally loaded SWF and I've loaded it with 2 different techniques hoping it was that but that didn't fix it.
I've tried simply placing a UiLoader and linking it and what it is now, a var myLoader.
Anyone run into something like this before?
You should try to be more specific in asking programming questions. I almost took it as a spam link.
Anyway's if I am getting you correct, the initial thumbnail clicks don't load the image.You should probably use individual loader for each of those large images.
