1 Win8 on Intel Programming Course Modern UI HelloWorld in HTML5/JS Cédric Andreolli Intel Software

2 Modern UI Coding Technologies available Javascript/HTML5 C#/XAML C++ Visual Basic

3 Modern UI Coding What will be covered Javascript/HTML5 The course is based on Visual Studio 2012 Lab A detailed lab is available in the ZIP file, with a doc file and sources.

4 Visual Studio 2012

5 Modern UI Hello World VS 2012 New project File > New > Project Select Blank app and enter an app name ( HelloWorld?)

6 Modern UI Hello World VS 2012 main window layout Run at the top, code at the center, solution explorer on the right

7 Modern UI Hello World VS 2012 solution = 1 or more projects

8 Manifest

9 Manifest What The manifest collect information about the application It's a XML document Contains The application's name The application's logo OS supported versions Application startup page,

10 Manifest

11 Manifest

12 Manifest What to remember Defines the start page! Place to add new capabilities (webcam, microphone, etc) Information about your applications

13 Resources

14 Resources Why resources? It s a very good practice is to avoid putting text strings directly into the code : use a resource file instead Your app will be easy to maintain and translate Here s how Create a directory named strings in your project Create a subfolder named en-us in the new strings folder Create a new Resources file in the new en-us folder

19 Start page

20 Start page A start page called «default.html» D

21 Start page The «default.html» file HTML5 format It's a good practice to associate a HTML file with a javascript file and a CSS file The default.html file is associated with js/default.js and css/default.css

22 Start page Anatomy of the «default.html» HTML5 file

23 Start page Vue and Controller The HTML5 is used to design the app window (Vue) It's possible to add texts, buttons, and a lot of other features Each element can be associated with handlers written in javascript (Controller)

24 Start page Let s add some elements to the home page A title A text input and its associated label A submit button A paragraph area to display some text File to modify Resources file for user visible readable strings Start page HTML5 file to add the elements Javascript file to add the desired behavior

25 Resources and HTML Resources : strings/en-us/resources.resjon HTML5 Start page : default.html

26 Resources and HTML Strings Strings are in the resources file, in JSON format, associated with keys Keys Keys are used in the HTML5 file instead of the strings data-win-res You must use the data-win-res attribute in the HTML5, in the tag, or as a span markup

27 Analysing the Javascript Javascript Insert the code for the behavior before app.start();

28 Editing the Javascript First load resources from Javascript

29 Editing the Javascript Then change the onactivated handler

30 Editing the Javascript setpromise Will display the splash screen as long as necessary WinJS.UI.processAll Will scan the associated HTML document getelementbyid( send ) Will retrieve the send button in the UI addeventlistener Will add a listener to the button

31 Editing the Javascript Add the handler before app.start()

32 Launch HelloWorld Click the Play button

33 Next steps

34 Next steps HelloWorld detailed lab We propose you open the associated lab (doc file) and code HelloWorld yourself. Plus/Minus app On top of HelloWorld, you ll find a slightly more complex example using the same technology, the Plus/Minus app.
