推荐答案

其实WM_DEVICECHANGE不太可能是你想要的。你可能想通过调用 RequestDeviceNotifications 并挂接到Windows CE的设备通知队列传递给它一个句柄与 CreateMsgQueue 创建一个队列。

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.

如果你不喜欢这样的P写入所有/调用code，像往常一样已经是智能设备框架已经它已经完成，并在一个更合乎逻辑的对象模型。

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.
