// TouchPadSettings.cpp : Defines the entry point for the console application.
// by windviki 2010/08/31// 轉載請注明出處。//// 辦公用的戴爾筆記本除了觸摸板，還在鍵盤中間有一個指點桿（point stick）// 打字很不習慣，經(jīng)常會碰到。于是想禁用掉這個指點桿。發(fā)現(xiàn)自帶的設置軟件需要.Net4環(huán)境支持。// 折騰完之后成功禁用。但是很郁悶的發(fā)現(xiàn)設置無法保存，重啟之后指點桿又啟用了。// 于是祭起windbg，得到一些參數(shù)值，寫了一個小程序來實現(xiàn)快速禁用或者開啟觸摸板/指點桿。設為開機啟動便解決了這個問題。// 以下提供兩種方法。第一種是直接用deviceiocontrol進行操作，第二種是調用其設置所用的dll導出的函數(shù)。// 至于官方控制程序無法保存設置的問題，現(xiàn)在發(fā)現(xiàn)可能是系統(tǒng)啟動的時候沒有正確的從注冊表里面讀取設置并應用到設備上所致。// 能否直接修改官方程序，留待后面有空研究。
