.net – 记录鼠标中键和滚轮滚动

我已经创建了一个类来记录鼠标操作,例如用鼠标记录任务(在这里移动鼠标并在那里单击左键然后……).

录制鼠标动作/任务后,我可以使用我制作的主题从类中重现它.

我需要的是实现鼠标的中间按钮和滚动滚动,但我不知道如何做到这一点,我有点难以使用和理解“GetAsyncKeyState”,我找不到信息关于“GetAsyncKeyState中间按钮状态”或滚轮滚动(向下/向上滚动).

您可以使用GetAsyncKeyState(4)获取鼠标中键.但是你永远不会用这种方法得到鼠标滚动消息,没有任何方法可以要求滚动按钮位置.您必须依赖于窗口消息,该消息告诉您鼠标已滚动,WM_MOUSEWHEEL.

即使您自己的窗口没有焦点也需要进行录制需要一种根本不同的方法,您需要使用低级别的钩子.由SetWindowsHookEx()设置的钩子,当鼠标事件发生时,它将调用程序中的方法.

没有必要发布代码,互联网上有很多可用的样本.适当的Google查询是“vb.net setwindowshookex wh_mouse_ll”. The first hit已经非常好了,微软知识库文章几乎拥有你需要的一切.它使用SetWindowsHookEx()的方式确实需要调整,如图所示它只会记录您自己程序的鼠标事件.相反,使用LoadLibrary(“user32.dll”)并将返回值作为第3个参数传递,第4个参数传递0以使其记录每个鼠标事件.
