• #18: [TDM, DEV][Windows 7 Taskbar Details]In the earlier taskbar posts, we discussed how Windows Media Player’s deskband offers valuable background music controls, but only a mere 3% of sessions ever enjoy the functionality. The new taskbar exposes a feature called Thumbnail Toolbars that surface up to seven window controls right in context of taskbar buttons. Unlike a Jump List that applies globally to a program, this toolbar is contextual to just a specific window. By embracing this new feature, Media Player can now reach a majority of peopleDoes your window require controls?Surface commands that users access regularlyCommands must be contextual to a windowDon’t duplicate Jump List tasksCan you replace a Desktop Toolbar?
• #19: Native codeUINT wm_tbc = RegisterWindowMessage( "TaskbarButtonCreated");MSG m; GetMessage(..., &m);if (m.message == wm_tbc) { ITaskbarList3* ptl = ...; THUMBBUTTON btn = {...};ptl->ThumbBarAddButtons(m.hWnd, 1, &btn);}
• #24: [TDM, DEV]All the major web browsers offer tabs and a method of managing these tabs. One could argue tab toolbars are really like taskbars since they facilitate switching. These TDI (Tabbed Document Interface) and MDI (Multiple Document Interface) programs have always resorted to creating their own internal window management systems as the Windows taskbar was not optimized to help their scenarios. Some programs like Excel did custom work to surface their child windows on the taskbar, but this approach was somewhat of a hack.Since the new taskbar already groups individual windows of a program under a single button, we can now offer a standard way for programs that have child windows to expose them. Again, the taskbar offers a single, consistent place to access real windows as well as child windows. These custom window switchers also behave as regular windows on the taskbar with rich thumbnails and even Aero Peek.Does your program have switchers that need to be surfaced?Do users need to regularly switch to them?Provide a visual representation for your client area’s switcherTaskbar bitmap (thumbnail)Peek bitmap (real size)

• #27: [TDM, DEV][Windows 7 Taskbar Details – Important enough to not hide]Jump Lists are a new feature of the Windows 7 taskbar that accomplish just this. Think of this feature as a mini Start Menu for each program or an evolved version of the system menu. First, the you don’t need to even start the program to quickly launch a file or access a task. Second, destinations don’t take up valuable space on the taskbar; they are automatically organized by their respective program in a simple list. Should one have ten programs pinned or running on her taskbar, this means she could have quick access to over 150 destinations she uses all the time, without even the need to customize the UI! Since the Jump List shows lots of text for each of its items, gone are the days of having identical icons on your taskbar that are indistinguishable without a tooltip. Should you wish to keep a specific destination around, you can simply pin it to the list.
• #28: [ DEV][Why - Windows 7 Taskbar details]Jump Lists are a new feature of the Windows 7 taskbar that accomplish just this. Think of this feature as a mini Start Menu for each program or an evolved version of the system menu. Jump Lists surface commonly used nouns (destinations) and verbs (tasks) of a program. There are several advantages this new approach provides. Do destinations apply to your program?Nouns: Items consumed/created by your programDynamic based upon individual user patternRecent or frequent or custom list?Do tasks apply to your program?Verbs: Program actionsTasks should not require your program to be runningTasks are static and apply to all usersTasks should globally apply to your program, not a specific window

• #32: 1 demo on Scenic ribbon
• #33: [TDM, DEV][What- Windows 7 Ribbon Platform overview]The Ribbon – a very successful concept from Office 2007 has become a first class citizen in Windows 7 and it is evolved into a developer platform. Many developers asked us to enable ease access to the office Ribbon. So in Windows 7 we have created the Ribbon which will also be redistributed available to Windows VistaIt is a Win 32 native COM base APIAnd it has a very close functionality to the office Ribbon

• #40: [TDM, DEV]Sensor Platform Windows 7 has changed how developers use sensors. It includes native support for sensors, expanded by a new development platform for working with sensors, including location sensors, such as GPS devices. Built on the Sensor platform, the Windows Location APIs are a new Windows 7 feature that enables application developers to access the user’s physical location information. The Windows Location APIs can abstract hardware, simultaneously support multiple applications, and seamlessly switch between different technologies, relieving the application developer of the burden of managing these constraints. The Location APIs can be used by programmers through the C++ programming language (by programmers familiar with COM), or by using COM objects in scripting languages, such as JScript®. Scripting support gives easy access to location data for projects such as gadgets or web pages.Windows 7 provides a solid, easy-to-use platform for using sensor devices, such as an ambient light sensor or a temperature gauge, to create environmental awareness in Windows applications. PCs can use sensors that are built into the computer, connected through wired or wireless connections, or connected through a network or the Internet.The Sensor and Location APIs provide a standard way to discover sensors, and to programmatically access data that sensors provideThe Sensor control panel lets users enable or disable sensors, control access to sensors that might expose sensitive data, view sensor properties, and change the descriptions of sensors.The Sensor Class Extension is a core part of the driver development model for the Sensor platform. It provides the following mechanisms, which are used when writing a User-Mode Driver Framework (UMDF) sensor driver:Integration with the Sensor platformSecurity enforcement
