这原先是昨天晚上我改了好久, 也不能让它支持两个手柄, 不知道是哪个关键代码错了. 其实有这方面经验的人只要稍稍指导一下就可以了, 帮帮我好不好?
比如要两个手柄, 是要有两个手柄的GUID呢, 还是要一个? 等等...
无论怎么写, 都不能让另外一个手柄好用...
我不想让你们看令人头疼的海量代码, 我只列出了部分关键代码..
这是照windows 2D游戏编程大师改的. 粘到下面格式就变得非常诡异了....

谁能帮我稍稍看一下, 说一下关键所在啊?
在此谢谢了[em3][em3][em3][em3][em3][em3][em3][em3][em3][em3][em3][em3][em3][em3][em3][em3][em3][em3]
