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。这是正确的做法吗？
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InitialTouchInject，它的Inject位返回false，我不知道为什么。
答案 0 :(得分：4)
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＃但没有放弃所有类型检查，指针和参数。之前引起头痛。
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。
