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? } public enum TOUCH_FLAGS { TOUCH_FLAGS_NONE = 0x00000000 } public POINTER_TOUCH_INFO create_pointer_touch_info(POINTER_INFO pointerInfo, TOUCH_FLAGS touchFlags, RECT rcContact, UInt32 orientation, UInt32 pressure) { POINTER_TOUCH_INFO mi = new POINTER_TOUCH_INFO(); mi.pointerInfo = pointerInfo; mi.touchFlags = touchFlags; mi.rcContact = rcContact; mi.orientation = orientation; mi.pressure = pressure; return mi; } public enum POINTER_INPUT_TYPE { PT_POINTER = 0x00000001, PT_TOUCH = 0x00000002, PT_PEN = 0x00000003, PT_MOUSE = 0x00000004 } public struct POINTER_INFO { public POINTER_INPUT_TYPE pointerType; public UInt32 pointerId; public UInt32 frameId; public HANDLE sourceDevice; public HWND hwndTarget; public Point ptPixelLocation; public Point ptHimetricLocation; public Point ptPixelLocationPredicted; public Point ptHimetricLocationPredicted; public POINTER_FLAGS pointerFlags; public DWORD dwTime; public UInt32 historyCount; // public UInt32 inputData; public DWORD dwKeyStates; public ULONGLONG Reserved; } public POINTER_INFO create_pointer_info( POINTER_INPUT_TYPE pointerType, UInt32 pointerId, UInt32 frameId, HANDLE sourceDevice, HWND hwndTarget, Point ptPixelLocation, Point ptHimetricLocation, Point ptPixelLocationPredicted, Point ptHimetricLocationPredicted, POINTER_FLAGS pointerFlags, DWORD dwTime, UInt32 historyCount, // UInt32 inputData, DWORD dwKeyStates, ULONGLONG Reserved) { POINTER_INFO mi = new POINTER_INFO(); mi.pointerType = pointerType; mi.pointerId = pointerId; mi.frameId = frameId; mi.sourceDevice = sourceDevice; mi.hwndTarget = hwndTarget; mi.ptPixelLocation = ptPixelLocation; mi.ptHimetricLocation = ptHimetricLocation; mi.ptPixelLocationPredicted = ptPixelLocationPredicted; mi.ptHimetricLocationPredicted = ptHimetricLocationPredicted; mi.pointerFlags = pointerFlags; mi.dwTime = dwTime; mi.historyCount = historyCount; // mi.inputData = inputData; mi.dwKeyStates = dwKeyStates; mi.Reserved = Reserved; return mi; } public enum POINTER_FLAGS { POINTER_FLAG_NONE = 0x00000000, POINTER_FLAG_NEW = 0x00000001, POINTER_FLAG_INRANGE = 0x00000002, POINTER_FLAG_INCONTACT = 0x00000004, POINTER_FLAG_FIRSTBUTTON = 0x00000010, POINTER_FLAG_SECONDBUTTON = 0x00000020, POINTER_FLAG_THIRDBUTTON = 0x00000040, POINTER_FLAG_OTHERBUTTON = 0x00000080, POINTER_FLAG_PRIMARY = 0x00000100, POINTER_FLAG_CONFIDENCE = 0x00000200, POINTER_FLAG_CANCELLED = 0x00000400, POINTER_FLAG_DOWN = 0x00010000, POINTER_FLAG_UPDATE = 0x00020000, POINTER_FLAG_UP = 0x00040000, POINTER_FLAG_WHEEL = 0x00080000, POINTER_FLAG_HWHEEL = 0x00100000 } [System.Runtime.InteropServices.DllImport("user32.dll", CallingConvention = CallingConvention.StdCall)] private static extern Boolean InjectTouchInput(UInt32 count, POINTER_TOUCH_INFO* pntTchInfo); [System.Runtime.InteropServices.DllImport("user32.dll")] private static extern Boolean InitializeTouchInjection(UInt32 maxCount, DWORD dwMode); private const UInt32 MAX_TOUCH_COUNT = 256; // Can be as high as 256 private const UInt32 TOUCH_FEEDBACK_DEFAULT = 0x1; private const UInt32 TOUCH_FEEDBACK_INDIRECT = 0x2; private const UInt32 TOUCH_FEEDBACK_NONE = 0x3; public unsafe static void MouseTouch(int x, int y) { bool ret = false; ret = InitializeTouchInjection(1, TOUCH_FEEDBACK_DEFAULT); if (!ret) { throw new NotSupportedException(); } Point point = new Point(x,y); POINTER_INFO ptrInfo = new POINTER_INFO(); POINTER_TOUCH_INFO* ptrTchInfo; ptrInfo.pointerType = POINTER_INPUT_TYPE.PT_TOUCH; ptrInfo.pointerId = 1; ptrInfo.ptPixelLocation = point; ptrInfo.pointerFlags = POINTER_FLAGS.POINTER_FLAG_PRIMARY; POINTER_TOUCH_INFO ptrTchInfobase = new POINTER_TOUCH_INFO(); ptrTchInfo = &ptrTchInfobase; ptrTchInfo->pointerInfo = ptrInfo; ptrTchInfo->touchFlags = TOUCH_FLAGS.TOUCH_FLAGS_NONE; ptrTchInfo->rcContact.X = x - 2; ptrTchInfo->rcContact.Y = y - 2; ptrTchInfo->rcContact.Width = 4; ptrTchInfo->rcContact.Height = 4; ptrTchInfo->pressure = 128; ptrTchInfo->orientation = 0; ret = InjectTouchInput(1, ptrTchInfo); if (!ret) { throw new NotImplementedException(); } } } 几乎所有这些我都试图从我在网上找到的InjectTouchInput API中解脱出来。 我可以初始化InitialTouchInject，它的Inject位返回false，我不知道为什么。
我继续根据Microsoft提供的示例在c ++中创建一些自定义函数，然后使用与之前相同的定义将其导入C＃但没有放弃导致头疼的所有类型检查，指针和参数。
我使用的DLL文件是TouchInjectionDriver.dll，可以在这里找到：

下面是我用来实现它的C＃代码。
