问题描述
我最近刚开始与InjectTouchInput的Windows 8消费者预览播放。我已经走了一圈又一圈的圆圈试图让混账东西来工作，但似乎仍不能得到它的实际互动。我工作在C＃和此刻的我只创造了两个文本框和调用下面的功能在这些坐标在屏幕上触摸按键与X和Y坐标的Metro界面。这是去了解这个干什么？
I've just recently started playing with the InjectTouchInput for Windows 8 Consumer Preview. I've gone round and round in circles trying to get the darn thing to work but just can't seem to get it to actually interact. I'm working in c# and at the moment am only creating a metro interface with x and y coordinates in two text boxes and buttons which call the functions below to touch on the screen at those coordinates. Is this the right way to go about doing this?
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?

几乎所有的，我已经尝试从InjectTouchInput API我在网上找到解除。我可以InitializeTouchInject罚款，其注入位这就是返回false，我不知道为什么。
Almost all of that I've tried to lift from the InjectTouchInput API I found online. I can InitializeTouchInject fine, its the Inject bit thats returning false and I have no idea why.
推荐答案
我继续创造一些在C ++中的自定义功能，根据微软提供的，然后就去使用相同的定义很多像以前一样，但没有放屁有关的所有类型检查，指针和论点是之前引起头痛进口的成C＃的样品。
I went ahead and create some custom functions in c++ based on the sample Microsoft provided and then went and imported that into C# using alot of the same definitions as before but without farting about with all the type checking, pointers and arguments that were causing headaches before.
这是我使用的DLL文件是TouchInjectionDriver.dll并可以在这里找到：
The DLL file that I've used is TouchInjectionDriver.dll and can be found here:
