2. Agenda

3. Agenda Introduction Taskbar Windows Ribbon Multitouch Sensors and Location More.. Resources and References

4. Common System Requirements Windows 7 Visual Studio 2008 SP1/ Visual Studio 2010 Beta 2 (or higher) Windows 7 SDK Windows API Code Pack for the .NET Framework Windows 7 Multitouch .NET Interop Sample Library

5. Windows7 API CodePack for .NET .NET Wrapper for Windows 7 ® features Taskbar, Libraries Sensor Location Multi-Touch UAC power management restart and recovery network awareness, Aero Glass and more.

6. Taskbar

7. Windows 7 Taskbar Taskbar Buttons Jump Lists Thumbnail Preview Thumbnail Toolbars Custom Switchers Icons Overlay Icons Progress Bars

8. Taskbar Buttons Quick launch User friendly Running application windows Running Not running Multiple windows Active

9. Destinations (“nouns”) Tasks (“verbs”) Known categories Custom categories User Tasks Taskbar Tasks Pinned category Jump Lists

10. Thumbnail Preview

11. Thumbnail Toolbars

12. Taskbar Overlay Surface important notifications Appears over your taskbar button

13. Taskbar Overlay Icons Code Snippets WinForms : TaskbarManager.SetOverlayIcon ( IntPtrwindowHandle , System.Drawing.Icon icon, string accessibilityText ) WPF: TaskbarManager.SetOverlayIcon ( System.Windows.Window window, System.Drawing.Icon icon, string accessibilityText )

14. Taskbar Progress bar Shows progress status Appears over your taskbar button

15. Taskbar Progress Bar Code Snippets WinForms : TaskbarManager.SetProgressState ( TaskbarProgressBarState state, IntPtrwindowHandle ) WPF: TaskbarManager.SetProgressState ( TaskbarProgressBarState state, System.Windows.Window window)

16. Windows Ribbon

17. Application Menu Quick Access Toolbar Tab Contextual Tab Set Contextual Tab Help Group (aka “Chunk”) Dialog Launcher In-box with Windows 7, redistribution available to Vista Win32 API, Feature parity (or close) with Microsoft Office 2007 Ribbon, and WPF Ribbon Windows Ribbon

18. Categorized Menus Tabs & Groups Color Pickers Mini Toolbar & Contextual Menu Dropdown Galleries Tooltips Check Boxes Spinners Font Control Group Dialog Launchers “In-Ribbon” Galleries Combo Boxes Buttons & Split Buttons Windows Ribbon - Controls

19. Windows Ribbon API Interfaces Consists of these main interfaces IUIFramework – initialize ribbon, load markup resource, get or set command property values or state, set application modes IUIApplication – user-implemented interface. Retrieves user command handler for each command defined in the markup. Notifies about view state changes IUICommandHandler – user-implemented interface. Handles commands, updates property value (for example, setting a command to enabled or disabled based on view)

20. Integrating Windows Ribbon Application Ribbon Platform IUIApplication IUIFramework CoCreateInstance Initialize (HWND, IUIApplication *) LoadUI ( resourceName ) OnCreateCommand IUICommandHandler Execute, UpdateProperty Get/ SetUICommandProperty , InvalidateUICommand

21. Multitouch

22. Multi-Touch Is Here! Hardware Multi-touch enabled hardware device Software Windows 7, .NET Framework 4.0 Consumers New scenarios, next wave of user experience, high “WOW” factor

23. We’ve identified several key scenarios for multi-touch: Navigating and consuming the web Reading & sorting email Viewing photos Playing casual games Consuming music and video Navigating files & arranging windows Using Office applications Multi-Touch Is Scenarios

24. Multi-Touch Development Tiers Good – Better – Best Windows application can target one of three levels of touch integration Good: No specific touch APIs are used but the application UI is appropriately sized and works well with the built-in gestures Better: The gesture APIs are supported to give smooth natural interactions Best: Deep touch-focused experiences designed to take advantage of multi-touch features

25. Good APIs For Free! Panning/zoom gestures Right-click gesture Native Win32 Controls with standard scrollbars WPF WPF 3.5 SP1 API CodePack WPF 4.0 full support + Controls WinForms Controls with standard scrollbars Best Raw touch data Manipulation and inertia processors WM_TOUCH COM-based manipulation and inertia processors Touch events Manipulation and inertia processors Manipulation and inertia processors via COM interoperability Better Gesture notifications Pan/zoom/rotate and so on WM_GESTURE message Gesture events Inertia configuration WM_GESTURE message via interoperability

26. Call To Action Decide the appropriate scenario that fits with concept of multi-touch feature Decide which tier of investment is appropriate Check your current applications Add Gesture Or manipulation Or inertia Build something amazing!

27. Sensors and Location

28. Few Real World Usage In a sunny day, an application might increase brightness, contrast etc An application might provide location-specific information, such as nearby restaurants An application might use a human presence sensor to change the state of the Messenger status

29. Sensor Platform Overview Windows 7 features a new API for working with sensors COM-based API Works with drivers using the sensor class extension You can seamlessly interact with any type of sensor, such as Ambient light sensor Temperature gauge GPS device etc

30. Location Platform Overview The Location API lets you obtain the location without caring about the particular mechanism used to obtain the information, for example, GPS cell-tower or Wi-Fi hotspot triangulation. The Location API automatically chooses the most accurate sensor data available.

31. Sensor and Location API: Benefits Hardware-independence: No need to target vendor-specific APIs or to know hardware specifics Application sharing: Multiple applications can consume data from the same sensor simultaneously

32. Privacy Privacy: Because Microsoft recognizes that sensor and location data are private, personally identifying information, all sensors are disabled by default.

33. Sensor and Location Platform Architecture – The Big Picture UMDF sensor driver Sensor class extension Sensor API Gadget or script Application Location and Other Sensors Control Panel Sensor device Location API Location IDispatch Interface Application UMDF sensor driver Sensor class extension Logical location sensor (Triangulation) User System

34. Sensor Wrapper Architecture Sensor is an abstract base class with a derived type for each sensor type Derived types can add properties and events

35. Receiving Data Reports from Sensor a3dSensor.DataUpdated += OnDataUpdated ; void OnDataUpdated ( Sensor sensor , SensorDataReport dataReport ) { Accelerometer3DReport a3dReport= ( Accelerometer3DReport ) dataReport ; Console .WriteLine ( "X: {0} Y: {1} Z: {2}" , a3dReport.AxisX_G, a3dReport.AxisY_G, a3dReport.AxisZ_G); }
