如何模拟windows的touch操作，奋斗了几天终于出结果了，网上搜索了一个c#版本的，但是总是没有效果，并且c#要求的条件比较多，于是自己写了一个autoit轻量级的版本。autoit代码：
#RequireAdmin
Local $retval = _SimulateTouch(10, 1000, 300, 300)
MsgBox(0, "", $retval)
; #INDEX# =======================================================================================================================
; Title .........: _SimulateTouch
; AutoIt Version : 3.3.6
; Description ...: Simulate touch action. The function can work on minimum supported client: windows8[desktop apps only] and minimum supported server: windows server 2012[desktop apps only]
; Author(s) .....: qlplwh@163.com
; Dll(s) ........: user32.dll
; Parameters.....: $TouchTimes-----------Touch times;
; $TouchInterval--------Touch Interval;
; $TouchCoordinates_x---Touch coordinates x;
; $TouchCoordinates_y---Touch coordinates y
; returns........: int touch success times
; Requirements ..:
