在C＃创建的PostMessage的（）一WM_TOUCH消息/ .NET [英] Creating a WM_TOUCH message for PostMessage() in C# / .NET

问题描述

（有关背景信息，请参阅<一href="http://stackoverflow.com/questions/12081167/composing-a-wm-touch-message-for-sendmessage-kinect-as-a-multi-touch-device">Composing对于SendMessage函数（），Kinect的为多点触摸设备一个WM_TOUCH消息，询问基本相同的问题，因为我的，但其接受的答案实际上并没有回答这个问题。棘手位不填写 TOUCHINPUT 结构，但做一个有效的触摸输入句柄。）

(For background, see Composing a WM_TOUCH message for SendMessage(), Kinect as a multi-touch device which asks basically the same question as mine but whose accepted answer doesn't actually answer the question. The tricky bit isn't filling in TOUCHINPUT structures but making a valid touch input handle.)

我想模拟多点触摸输入设备的presence在一个讨厌的hackish的方式，这在大纲是这样的：

I would like to simulate the presence of a multi-touch input device in a nasty hackish way, which in outline goes like this:

while (true) {
  choose locations etc. for simulated touches;
  PostMessage(GetForegroundWindow(), WM_TOUCH, nTouches, ...);
}

棘手位是善有善报在标有空间......。 MSDN文档，这是勿庸置疑从一个的消费者的角度编写的的 WM_TOUCH 的消息说，在的lParam 为 WM_TOUCH 消息

The tricky bit is what goes in that space labelled "...". The MSDN documentation, which is unsurprisingly written from the point of view of a consumer of WM_TOUCH messages, says that the lParam for the WM_TOUCH message is

的触摸输入手柄，可用于在调用 GetTouchInputInfo 来检索有关与该消息相关联的触摸点的详细信息。

a touch input handle that can be used in a call to GetTouchInputInfo to retrieve detailed information about the touch points associated with this message.

我可以很轻松地做，比如，对 TOUCHINPUT 结构数组，这就是 GetTouchInputInfo 给你。但是，这似乎是从一个触摸输入句柄是完全不同的事情。 （例如，触摸输入句柄必须是正确的事情传递给 CloseTouchInputHandle ，据称 PostMessage的或 SendMessage函数就可以了。）

I can easily enough make, e.g., an array of TOUCHINPUT structures, which is what GetTouchInputInfo gives you. But that seems to be an entirely different thing from a "touch input handle". (E.g., a touch input handle needs to be the right sort of thing to pass to CloseTouchInputHandle, which allegedly PostMessage or SendMessage will do.)

是否有可能（正式或非正式的！）用户code，以产生一个有效的触摸输入处理，它可以传递给 PostMessage的？如果是这样，如何​​？

Is it possible (officially or unofficially!) for user code to generate a valid touch input handle that it can pass to PostMessage? If so, how?

推荐答案

Windows 8的具有在桌面环境伪造倒是一个TouchInjection API。

Windows 8 has a TouchInjection API for faking touches in the Desktop Environment.
