If X 0 Then X = 2 : VX = -VX
If Y 0 Then Y = 2 : VY = -VY
If X Width - 移动控件.Width Then X = Width - 移动控件.Width - 2 : VX = -VX

vb点虐 中如何禁用键盘和鼠标
很简单，你怎么不先问我，还在这提问。用api函数，钩子，设置成全局钩子，然后对钩取来的message消息不做处理，也不返回，这样屏蔽了键盘了。钩子函数api好像是什么hook的那个，还有钩子函数的返回函数，以整个自定义函数的指针作参数
寻VB.NET下winio(驱动级模拟按键)的键盘使用方法
这是不可能完成的任务，.NET平台不存在开发驱动的能力，你要想在驱动层对键盘操作，最好使用C,C++来实现，比较方便。 像现在一些比较出名的网络游戏，都是在驱动层进行保护的。
