我正在尝试通过 Windows 中任何程序上的“键盘和鼠标”来检测用户活动。

我GetAsyncKeyState()在user32.Dll“.

我通过以下方式检测鼠标移动System.Windows.Forms.Cursor.Position;

我正在寻找一种方法来检测Windows 中任何程序和屏幕上任何位置上的鼠标滚轮滚动。

我知道它可以通过user32.Dll像GetMessage(). 我从不使用像MouseWheelEvent 这样的寡妇表单控制事件，因为它只适用于当前程序，根本不适用。

谢谢。

好问题

如果这有帮助，下面是一个具有大部分鼠标钩子的类，因此您可以选择 make an 来使用它，您必须分配标准点击

mhM.SetHook();
