Project “Hilo”, A Complete C++ / Windows 7 Sample Application

  • Article

The C++ team has introduced a new sample series designed to demonstrate building a rich Windows 7 application for working with pictures, from scratch.  Each step will add new features including touch, animation, etc.  You can read more about the sample series and download full source code from the main site.

The first version builds a carousel control for displaying pictures and includes browsing support:

The application is written completely in C++ directly against Windows (no frameworks).  It takes advantage of new WIN32 API’s,

such as IUIAnimationStoryboard which is a new feature in Windows that allows one to do animation storyboards:

     MIDL_INTERFACE("A8FF128F-9BF9-4af1-9E67-E5E410DEFB84")
    IUIAnimationStoryboard : public IUnknown
    {
    public:
        virtual /* [annotation] */ 
        __checkReturn
        HRESULT STDMETHODCALLTYPE AddTransition( 
            /* [annotation][in] */ 
            __in  IUIAnimationVariable *variable,
            /* [annotation][in] */ 
            __in  IUIAnimationTransition *transition) = 0;
        
        virtual /* [annotation] */ 
        __checkReturn
        HRESULT STDMETHODCALLTYPE AddKeyframeAtOffset( 
            /* [annotation][in] */ 
            __in  UI_ANIMATION_KEYFRAME existingKeyframe,
            /* [annotation][in] */ 
            __in  UI_ANIMATION_SECONDS offset,
            /* [annotation][retval][out] */ 
            __out  UI_ANIMATION_KEYFRAME *keyframe) = 0;

The C++ team wants to make this series a long term investment which is useful for you. Please do send us your feedback so we can use it to shape future installments.

Enjoy!
