I am trying to store data in a "Metro" App for Windows 8 using IndexedDB.
I would like to be able to browse the database (to monitor that my operations modify the data as intended). So my question is; Is there any way of viewing the actual database of a metro app (IE10)? (something like in Chrome Dev Tools (Resources > IndexedDB))
Regards
The IE team has a blog post Debugging IndexedDB Applications that includes an IDBExplorer module that you can incorporate into your application (for testing, not recommended for production)
Not that I know, but my linq2indexeddb library has a viewer in it. That way you can inspect the content of you database while debugging. The nuget package for Metro apps can be found here. And as last, I have a blogpost on how you can use it.

I am working on a Hybrid Application, targeting (for the moment) iOS. Does Worklight have a utility to handle application settings/preferences for iOS? I know how to write the native code to do this, but do not yet know how to gain access to the application settings from the JavaScript. Can anyone point me in the right direction or provide a working example?
In application-descriptor.xml, there is a worklightSettings flag you can set, however the settings page it creates is not user facing. That is, it is meant only for development time, or internal usage, and not production. It allows control of the server address that athe client connects to and change the web resources it will fetch.
So the answer is, no.
The mentioned settings page has set items in it that cannot be altered much (settings.bundle which does not allow much room for play. Maybe you could change it a bit, but doing so would void giving support to you if problems arise). I would recommend against doing so.
So this leaves you the option of creating this on your own. Maybe there is an existing Cordova plug-in that does something similar. Review these training modules of how to incorporate Cordova plug-ins to your application. Cordova bridges between JavaScript to native code, so it could be what you're looking for.
I have a project that loads http://ajax.googleapis.com/ajax/libs/dojo/1.3.2/dojo/dojo.xd.js, I want to be able use this project offline
I tried to download dojo.xd.js and link to it locally but this still doesn't work offline
In firebug, on the net tab I can see that there are a lot more .js files that load
Is there a simple way of making this work offline?
The way of integration depends on your way of using it.
I assume you have webserver running locally (without inet access)?!
At the dojo website there are several ways of dojo integration available. Just download one of them (do not use CDN) and put the file on your local web server. Then it is available through the local url (can be relative to your site).
If you wan't to build an "offline" app without a webserver then take a look at Adobe AIR and interation of the dojo toolkit with Dojo Extensions for Adobe AIR.
Another option might be the integration together with PhoneGap or Cordova to build an offline App, e.g. for an IPhone etc. with HTML/Javascript. Win8/RT Applications for the M$ AppStore does support HTML/Javascript, too (have not tested this with Dojo).
Keep in mind there are also some security restrictions (e.g. loading and execution of JavaScript) if you plan to "release" your app as simple html file (click to open in browser).
I have read some posts on S/O and also around the web. We are producing a HTML5 JS based web app that runs on the web. We are packaging it up for Google apps, and also for phonegap.
Can we package this app for windows 8? Of course, I appreciate it won't use the windows 8 features. But, will the app run none the less, as it stands. So that we can place it in the store and build out windows 8 features as we move forward.
I appreciate this is a slightly non-concise question, but I guess the real point is what is our quickest route to take our existing HTML 5, CSS, JS App and deploy it in the store and get it working on this platform.
In general, the answer is yes. The transition is not seamless, but you will be able to use a ton, if not all, of the application artifacts in Win8. A good test is if you can run it in IE10, you can run the app as a Win8 app. Again, this is a very broad brush - things you need to worry about are things like all scripts files need to be local (no CDN), changes to web and security contexts, and the fact that Win8 is a horizontal paradigm whereas most web apps are vertical. But in general, you should be able to make the move. Usual caveat - your mileage will vary.
Yes, although not recommended, you can package your existing app for Win8. You'll need to add a few bits of code though. The minimum would be to embed your app's start/init code within WinJS's first promise callback, like so:
args.setPromise(WinJS.UI.processAll().then(function () {
// your init code
}
You'll also need to create a couple of icons for the start screen and an image for your app's launch screen.
It is possible that you'll run into a few issues, like some security related restrictions, where you'll have to modify your code to use some native WinJS functions. This all depends on you app's implementation.
You can also check Microsoft's guidelines for migrating a web app to win8, here: http://msdn.microsoft.com/en-us/library/windows/apps/hh465143
I want to first of all thank everyone for the help I got here in the past. After completing my web application using Html, PHP, jQuery, Javascript, CSS, MYSQL, I realized I don’t want a website. In the end, for security, I prefer knowing who will be accessing my application. Having said that, I want to use most of the work I already did for my website. I understand I can use PHP with AIR and MySQL. I read that many would recommend using SQLite, but my problem is that I will constantly be updating the database. I also read there are some security issues using MYSQL and AIR.
Question 1, if I took the "necessary" security precautions within PHP which connects to MYSQL, would that be ok or is there soething else I should be aware of wit AIR ?
Question 2 if I really need to use SQLite, is there a way to connect to Mysql so that I may update the database.
I'm open to suggestions if there is a third party software that will covert my project to a desktop application with connectivity to MYSQL I also have a third party flash embedded.
Thanks
Make it mandatory to sign in to the website to use it. Will that not be sufficient to know who is accessing your application?
PHP is a server side language. Adobe AIR is desktop application framework. I am not sure that converting a PHP-MySQL application to an Adobe AIR application will be a trivial task.
You can take the distributed application route though by doing the client side in AIR and writing the web services in PHP/MySQL. And if you want a distributed database too, it will get lot more complicated.
You can build a rest api with php and integrate it with adobe air applications via http no need js for this. Just use actionscript with urlloader urlstream.
If you need an offline db you can use sqlite and sync with Mysql via php.
You'll have to forget PHP and use javascript and SQL sintax to do it. You can check this pretty guide from adobe to do so http://help.adobe.com/en_US/air/html/dev/air_htmldevguide.pdf
It won't be easy ;P
How can I develop an installable desktop application on top of the Mozilla Engine or the Webkit engine.
We want to have best of both worlds, ease of development with DOM+Javascript+RenderingEngine+ContinuedImprovements in a Browser and user's control as in a desktop app
I looked at using C++ XPCOM for Mozilla but it seems to be quite complicated, Is there any other way to code like a WebApp using Javascript but burn it into the browser and dress it to give a feel of a desktop app. Also I require that javascript is compiled into native so that one cannot sneak into the source code
Are there any examples of desktop applications done this way ?
Web apps are fine but there are concerns of piracy, privacy, security and version control. The moot point is that in a web app the control lies with the software vendor, moreover the data is also with the vendor. Not only these, any changes to the application may also necessitate another around of training. What we want is that once the customer buys a version he is sure of what he owns and that he is in total control of it and we as software developer do not exposed our source code.
The issue is we have expertise in Web App development and we want to utilize that to develop a Desktop App
Your last point is that :

Well then BowLine can be an option though it requires Ruby, so you need to consider that. You can also take a look at WebKitDotNet if you are with .net Background.
Use XUL for the user interface and code your functions using JavaScript. You problably only need C++ to expose native functionality not yet available in Gecko. Examples of software that works this way: Komodo IDE, Songbird, Firefox and Thunderbird.
