I'm used to creating web apps. Using cpanel and mysql database. I am looking into creating desktop application with a similar web app concept with multiple users, login system and basic CRUD operations. In web app we simply host the website and use cpanel and mysql . How about in desktop application? what are the normal practices for creating a desktop application and storing data online(like cpanel's php myadmin)?
please advice. Thank you very much.
This is not the best answer but Simple solution for lazy people like me. The best practice for this in my point of view is creating the desktop app via WebView for example if you want use java for the Desktop then there's WebView interface In JavaFx for webpages the WebView works like a browser it include HTML5 and CSS3 or Electron which is framework for creating Desktop app via web technologies. You can find more info about it.

Have you already developed a Xamarin app whose views are generated from a Json recovered when launching the application?
I met a client with this kind of need:
they are developing a web app to prototype the screens by adding and positioning some controls (TextBox, Label, ...)
this generates a Json that must be interpreted by the Xamarin app: this will build the different views dynamically
in a first version, the user's data would be stored locally (through a file or SQLite) and synchronized "manually" when the device is connected to a computer
the app will work on Android only in a first time, and then on WPF
The client has not yet decided between Xamarin.Forms or Xamarin native, but it's probably more interesting to do it through Xamarin.Forms, even if iOS is not required: this should make porting on WPF easier.
Have worked on similar cases? Have you some recommendations? Are there plugins or patterns that could be used to simplify this development?
I've found this one, but it doesn't seem to be the same use.
There is also this article on iOS, but there is not the same thing on Android.
This would in theory be possible using a massive code behind builder for a page but should NOT be done for a production app. Mobile apps have very specific requirements that need to be thought of before attempting.
Xamarin is great for simplifying code reuse, and if you use Xamarin Forms you can reuse the UI components for Enterprise apps.(the less fancy and pixel perfect the layouts need to be the better. )
Your client would be better served by making it a mobile compatible web page instead from the details you have shared.
I am currently on a research understanding the whole buzz around some technologies that claim that they deploy themselves as cross-platform apps once you write your code in HTML5/CSS3/AngularJS/Whatever client side techonology.
I understand those technologies provide you with a bridge to the native-side of the OS you are running on, but I still lack some real important information regarding them.
Do all those PhoneGap/Ionic/Cordova just wrap your client-side code into an application? Is it the same as using the web-browser to get to a URL but with only some native-like additions(Camera/File etc..).
Do those technologies just connect to your website that is online using DNS? Or is the "Website" you are building does not sit on a server but only on the local OS? Can they run that application offline?
Besides the native additions you get with those kind of technologies, why bother developing with them when you can on the other hand develop a responsive website that can also work on desktop?
Can you connect to a server-side using Ionic/Phonegap? Let's say I have an MS-SQL Table I want to communicate with- is that possible?
I really have a hard time understanding what all those technologies are any good. Still, it is growing in popularity. Thanks for any light on that matter.

They wrap your html, css and javascript code and provide a javascript API to use native features

server but only on the local OS? Can they run that application

You should have all the html, css and javascript inside of your app, if you do it this way the app will work offline.
You can have it online too, but it won't work offline and have some problems.
Besides the native additions you get with those kind of technologies,
why bother developing with them when you can on the other hand develop
a responsive website that can also work on desktop?
If you don't need any of the native features phonegap provides, then do a responsive website, the idea of phonegap is fill the gap between the browser and the native apps, some day the browser will have access to all the native features and phonegap will die.
BTW, now phonegap have a desktop platform, so you can make it work as native app for phone and still work in the browser
Can you connect to a server-side using Ionic/Phonegap? Let's say I
have an MS-SQL Table I want to communicate with- is that possible?
Sure, you can make XHR calls to the server to get a XML, JSON, etc with the onlyne SQL database, you can do a POST too, and upload files.
I thought PhoneGap was a simple wrapper for HTML5, but it looks like it does in fact compile into native in some way.
I have a Cloud based, HTML5 Single Page Web application that I just want to run full screen, and distribute via an app store.
Should I just create a PhoneGap App with an InAppBrowser?
If you intend to publish an HTML5-based app in a "native" app store sucha s Google Play or Apple Store, you have 2 options:
1- Implement your own native application using a webview to show your web-based app.
2- Use some existing framework like Phonegap/Cordova even you do not use the native API. The framework will already setup everything for you to just deploy your HTML5 code.
However, if your web app is meant to be hosted remotely (i.e. not run from local files), you may encounter problems when trying to publish in the Apple Store. They have some strict rules about remote content, and about publishing apps that may not provide much more value and/or functionality than a simple web-app can.
Best.
I have read a few forums and articles on this but can't get a clear answer.
I need to build a mobile app that can run on any platform/device. It looks like HTML5 + jquery is the best option but I need the application to do the following:
The app must run on any platform (Windows Phone, iOS, Android, etc).
It must work as a stand alone application. Meaning it must work without internet connection.
Because it is stand alone, I need a local database on the device. The database can be embedded in the app. I'm thinking SQL CE.
The local database on the device must be able to sync to a SQL Server database.
The app needs to interact with features of the device like the camera, or GPS device.
Is it possible to build such a mobile application?
I am using ASP.net MVC 4 to do the development.
If you want to use HTML5 and JQuery then the PhoneGap/Cordova framework would suit you best.
Phonegap is a cross platform framework that gives you access to the device features like GPS and Camera using a standard javascript API.
The app must run on any platform (Windows Phone, iOS, Android, etc).
Phonegap is compatible with all these and many more including blackberry. See here for full list: http://phonegap.com/about/feature/
It must work as a stand alone application. Meaning it must work without internet connection.
PhoneGap runs as a native application inside each devices webview. It does not need access to a data connection to run
Because it is stand alone, I need a local database on the device. The database can be embedded in the app. I'm thinking SQL CE.
PhoneGap cannot run its own SQL Database like a standard native application but it can use the web standards Web Storage and Web SQL. Though this approach does have limitations. Read more about this here: http://docs.phonegap.com/en/1.2.0/phonegap_storage_storage.md.html#Storage
The local database on the device must be able to sync to a SQL Server database.
This would be upto you to design and implement but can definitely be done
The app needs to interact with features of the device like the camera, or GPS device.
Most device features supported with PhoneGap. See above link for full support list.
If the lack of a full SQL Database support is a problem for you there are frameworks like Titanium Appcelerator that build a fully native cross platform app for you that may be more suited to your situation.

But if you're using HTML and JQuery to go cross platform then PhoneGap is your best bet.
Edit: Also there are plugins for PhoneGap to run a standard SQLite DB but this requires extra work on each platform. Every platform you develop for would require a compatible plugin.

Is there any GUI framework that can render a UI I create both as a web app and a desktop app, like on created with Qt or GTK? What I do not want is a "native" app that just displays the HTML UI in a window.
Have a look at Silverlight if you don't mind .NET coding. It is possible to do desktop and web using the same codebase. See example here
You can create native apps for Linux-based OSes easily using Quickly.
Also, in the event that you decide to just create a native app that displays HTML, note that Prism will be a good platform to use.
It will probably save you a lot of time to just have a native app shell that displays the HTML, because there will be no extra coding.
I don't know of any programs that will convert HTML directly into native UI.
There is an effort to realize this for Qt using QML:
