Native app for pairing Wifi on Glass contains QR scanner. Is it possible to use it via Intent in GDK? It would be useful for many use-cases.
At the end I solved it by using ZBar instead of ZXing. It was easier to integrate.
I have based my implementation on glassware GlassWifiConnect.
Result can be seen in glassware Glasquare.
As far as I know, that's an in app feature of the setup app. I'm currently working on porting over the ZXing barcode scanning app to Glass. Feel free to steal from it. The source is located on GitHub.
Also, one of the intents of this port is to allow other apps to request for barcode scanning, just like the original did, but it's not currently there yet. From a usability standpoint though, I feel that asking a user to install another app to do just the scanning is not ideal but it depends on user base or case. Either way, you are more than welcome to contribute if you feel that feature is necessary.

There is some libraries that lets you run C++. So, it is it possible to run a game that uses directx full mode screen?
Google is developing a tool to allow this kind of thing via Chrome. It is called Chrome Native Client, or NACL for short. http://blog.chromium.org/2010/05/sneak-peek-at-native-client-sdk.html
In general, no. Most online games are written with Javascript, Flash, the newly hatchedd HTML5 and similar technologies. Perhaps C++ integration is possible on some level, but you definitely cannot write a browser-hosted game purely and entirely in C++.
it could also be done with an ActiveX control. ActiveX only works in IE. there are Netscape plugins that work in other browsers. so make a solution that contains both. you need a book on ActiveX/COM/OLE. Better yet, take a class if you can find one, you will learn far more, because COM is not an easy subject to just read about and then really do - versioning is a big problem.
nope, not supported in firefox. but read this: http://www.google.com/chrome/intl/en/webmasters-faq.html#activex
some people may have activex controls disabled. if this is the case, your game will not run. you will have to tell the user that they will need to change their security settings in IE. you can get feedback from the object element in javascript as to whether or not the activex loaded. there is code out there for that.

Hey there,
So I've been heavily focused on design/development using web technology for the last few years (php/mysql, javascript, etc), and I'm a bit hesitant to start learning C++.. At the same time, I see it as a potentially enjoyable learning experience.
To keep things brief, right now I'm developing an online app that plots out certain locations on a map, and you can sort through these locations and do a bunch of other nifty things..sorry to be vague. The point is: I don't see any real advantages of making this an actual "app" when the entire functionality of the app itself can do quite fine through the modern mobile browser..
Not to mention that, by living in a browser, it's much less proprietary
So, my question is: Is there any way to make a simple app that's basically porting the user to my site? I guess it'd be convenient that as an app, the user has a nice little icon to click on when they do need to access it..
Android development relies heavily on Java. So you are all ready on the right track.
However if you just want to make an app that brings people to your website, running javascript I am guessing, this is easy to do with android.
Android supports the webkit browser and has a view group called WebView. Your app can be nothing more than a shortcut on a desktop that opens a webview directly pointed to your website. It could add other options to point to other parts of your website like bookmarks.
WebView webview = new WebView(this);
setContentView(webview);
weview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("yoursiteurlgoeshere);
A lot of apps on the market are actually based around a WebView. There are other classes that allow you more control over the view, like whether links are opened in the webview or in a new browser, or whether the user is allowed to use the resize options, etc.
Welcome to Android.
There is a massive article on exactly this type of idea. It discusses a number of different things and is well worth the read if you are indeed interested in making a cross-phone web-app. It talks about an html5 facility in the works for creating such a thing as you describe, but it isn't quite universal yet.
Here is an article on making an iphone app in html5.
You can also use phonegap to port your design to andorid.
also, check out a jquery plugin calld jqtouch if you are interseted in developing touch capable applications quickly.
If you are worried about speed and the issue of internet connectivity, you can use html5 local storage features which are available on both android and itouch. Ibm has a great series on these issues and part 2 covers local storage.
No. The problem with web technology on a mobile device is the delay. You are far away from the server, so a lot of the things you can easily do with a normal client creates a very bad user experience on a mobile device. The roundtrip time is simply too large. You have to move much more functionality to the client. This client is also less powerfull, and tends to have limits on caching large elements
How is this related to C++?
There is also a C++ API which is only recently available. Google calls it the NDK (Native Development Kit). Information about it can be found here: http://developer.android.com/sdk/ndk/index.html
I personally haven't developed using the NDK. The only real reason someone would really need to would be to write a high-performance application that can't stand the overhead of the Java JVM--which is getting more and more rare these days IMO.
As far as creating a simple app with a web container in it, see Phobos' response. That is exactly how I'd do it personally.
Is there a relatively easy way to display the output of a C++ program on a webpage? And I don't mean manually, in other words, you see it on a webpage as it runs not as in I make a code tag and write it in myself.
EDIT: Just so everybody can get this clear I am going to post this up here. I am NOT trying to make a webpage in C++. Please excuse me if this sounds spiteful or anything but I am getting a lot of answers relating to that.
Step one, get yourself a server-side language. Be that PHP, ASP, Python, Ruby, whatever. Get it set up so you can serve it.
Step two, find your language's exec equivalent. Practically all of them have them. It'll let you run a command as if it were from the command line, usually with arguments and capture the output. Here's PHP's:
http://php.net/manual/en/function.exec.php
Of course, if you're passing user-input as arguments, sanitise!
I've just seen that you accepted Scott's answer. I usually wouldn't chase up a SO thread so persistently but I fear you're about to make a mistake that you'll come to regret down the line. Giving direct access to your program and its own built-in server is a terrible idea for two reasons:
You waste a day implementing this built-in server and then getting it to persist and testing it
More importantly, you've just opened up another attack vector into your server. When it comes to security, keep it simple.
You're far better having your C++ app running behind another (mature) server side language as all the work is done for you and it can filter the input to keep things safe.
You could write a CGI app in C++, or you could use an existing web server language to execute the command and send the output to the client.
You want to use Witty.
Wt (pronounced 'witty') is a C++
library for developing interactive web
applications.
The API is widget-centric and similar
to desktop GUI APIs. To the developer,
it offers complete abstraction of any
web-specific implementation details,
including event handling, graphics
support, graceful degradation (or
progressive enhancement), and pretty
URLs.
Unlike many page-based frameworks, Wt
was designed for creating stateful
applications that are at the same time
highly interactive (leveraging
techinques such as AJAX to their
fullest) and accessible (supporting
plain HTML browsers), using automatic
graceful degradation or progressive
enhancement.
The library comes with an application
server that acts as a stand-alone web
server or integrates through FastCGI
with other web servers.
I am not sure this is what you are looking for but you may want CGI You may want to look at this SO question, C++ may not be the best language for what you want to do.
based off the questions you posted Writing a web app like what you want is no simple task. What I would recommend is use some other library (this is one i found with a quick google) to get a web console on your server and give the user it is running under execute deny permissions on every folder except the folder you have your app installed.
This is still is a risky method if you don't set up the security correctly but it is the easiest solution without digging around too much on existing libraries to just have the application interactive.
EDIT --
The "Best" solution is learn AJAX and have your program post its own pages with it but like I said, it will not be easy.
It sounds like you want something like a telnet session embedded in a webpage. A quick google turns up many Java telnet apps, though I'm not qualified to evaluate which would be most ideal to embed in html.
You would set up the login script on the host machine to run your c++ app and the user would interact with it through the shell window. Note though that this will only work for pure command line apps. If you want to use a GUI app in this way, then you should look into remote desktop software or VNC.
It may be worth looking into Adobe's "Alchemy" project on Adobe Labs
This may help you with what you're trying to achieve.
:)
Are you looking for something like what codepad.org does? I believe they explain how they did it here.
There is a library called C++ Server Pages - Poco. I used it for one of my college project, its pretty good. There is also good documentation to get started with, u can find it here http://pocoproject.org/docs/
What libraries / projects is to identify / authenticating to web apps using the voice?
Since there are still no answers for this question and it's been two years, I feel like there should be at least a follow-up.
Authenticating to an app using your voice is a very complex and difficult subject. Each case would probably require severe customization and as of right now I believe there is no out-of-the-box working solution to do it. The subject of speech/speaker recognition is still an academic subject.
One might use HTK or Sphinx to build one's own authentication tool. It is entirely possible, though quite difficult and still prone to false positives and/or rejections.
As for authenticating in the web - it adds some technical difficulties which, however, can be overcome. You would have to somehow get a sample, either by using a java applet or flash (something that can acces the microphone anyway), then submit it for analysis (may happen in the same applet), then pass the results to your web application.
For anyone still thinking about the problem: I'd suggest building a sphinx-4 based Java applet for authentication. It is possible, though time-costly and requiring some advanced knowledge.
I have this program in mind that I would like to attempt and create in c++. I am not sure what SDK I should use, Here is the idea:
Basically like Facebooks status' or twitter but strictly for your desktop. Window like AIM or MSN would allow you to view your friends and their current status, allow you to comment on it, etc. When someone changes their status, all of their friends get a little notification on the bottom right of their screen saying what their friends current status is. There would obviously be much more that sets it apart, but this is the basic idea that I'm starting from.
If you plan to release it as OpenSource, the Qt GUI Framework is very much worth considering (you can buy a commercial license too). It is crossplatform (Linux/Win/Mac) - eg. Google Maps desktop app uses it.
It will give you networking support, HTML/XML rendering if necessary, SQL and much more.
As for communication protocols, go with Greg's suggestion.
A good choice for a cross-platform GUI system is wxWidgets. For communication between users, something like XMPP would be a good option, because it is a platform-agnostic open standard with solid support for user "presence".
Qt is a good crossplatform toolkit. Take a look at that.
