推荐答案

实际上，WM_DEVICECHANGE成为你想要的。您可能希望通过调用 RequestDeviceNotifications 来钩到Windows CE的设备通知队列，将传递给使用 CreateMsgQueue 创建的队列的句柄。

Actually WM_DEVICECHANGE is unlikely to be what you want. You probably want to hook into Windows CE's device notification queue by calling RequestDeviceNotifications and passing to it a handle to a queue created with CreateMsgQueue.

如果你不想编写所有这个P / Invoke代码，像往常一样，智能设备框架已经有了它，并且在一个更逻辑的对象模型中。

If you don't feel like writing all of this P/Invoke code, as usual the Smart Device Framework already has it already done and in a more logical object model.
