InjectTouchInput Windows 8 C#无法正常工作(返回false)

我刚刚开始使用InjectTouchInput for Windows 8 Consumer Preview.我已经四处乱逛,试图让这个糟糕的事情发挥作用,但似乎无法让它实际上互动.我正在使用c#,目前只在两个文本框和按钮中创建一个带有x和y坐标的metro接口,这些按钮调用下面的函数在这些坐标处触摸屏幕.这是正确的方法吗？

protected unsafe class TouchDriver

        public struct POINTER_TOUCH_INFO {
            public POINTER_INFO pointerInfo;   // An embedded POINTER_INFO header structure.

            public TOUCH_FLAGS touchFlags;          // Currently none.

            public Rect rcContact;             // Pointer contact area in pixel screen coordinates. By default,if the device does not report a contact area,this field defaults to a 0-by-0 rectangle centered around the pointer location. 

            public UInt32 orientation;         // A pointer orientation,with a value between 0 and 359,where 0 indicates a touch pointer aligned with the x-axis and pointing from left to right; increasing values indicate degrees of rotation in the clockwise direction.
                                        // This field defaults to 0 if the device does not report orientation.

            public UInt32 pressure;            // Pointer pressure normalized in a range of 0 to 256.
                                        // This field defaults to 128 if the device does not report pressure.
                                        // Question: Can this go from 0 to 1024 to match pen pressure?

几乎所有这些我都尝试从我在网上找到的InjectTouchInput API中解脱出来.我可以初始化InitialInTouchInject,它的Inject位返回false,我不知道为什么.
