Question

我希望能够检查鼠标是否向下或向上忽略虚拟点击。我正在制作一个程序，当按住右键单击按钮时发出右键单击，如果我在任何其他按钮被按住时绑定垃圾邮件右键单击，我的程序将起作用。它无法正常工作，因为它将模拟的点击作为按钮向下然后向上注册。因此，它只会点击一次，直到它认为鼠标因虚拟点击而未被保持。此外，如果你知道一个程序执行此操作，那么下载它会很不错。

通过使用鼠标处理程序事件，您无法区分＆＃34;硬件＆＃34;和＆＃34;软件＆＃34;点击。鼠标驱动程序生成完全相同的事件，您可以通过SendMessage以编程方式创建这些事件。＆＃34;低水平＆＃34;事件只不过是全局捕获这些软事件，然后您可以映射到控件或其他任何事件。

因此，如果您想实现这一目标，您应该编写自己的API，通过USB，PS2或RS-232物理接口询问物理信号。

但你是什么意思＆＃34;硬件状态＆＃34;在VM？还是在线申请？例如，谷歌选择了另一种方式to differentiate real and soft clicks：而不是尝试使用任何＆＃34;低级别访问＆＃34; （无论它意味着什么），它们检测鼠标移动和点击是否自然或过于规则，这可能表示软件调用了点击。

如何检查鼠标的硬件状态？
