I an trying to write a simple Windows Service that shall detect any incoming USB device and Launch a GUI application.

            WqlEventQuery query = new WqlEventQuery("SELECT * FROM Win32_VolumeChangeEvent WHERE EventType = 2");
            watcher.EventArrived += watcher_EventArrived;
            watcher.Query = query;
            watcher.Start();
            watcher.WaitForNextEvent();

This solution works well in Win 7 However, it fails in XP (I have XP SP3).

I found another solution here

http://www.codeproject.com/Articles/63878/Enumerate-and-Auto-Detect-USB-Drives

This works very well in windows forms application even on windows XP, However it fails when I put it in service even on Win 7

Can you please help?

EDIT 1: Presently there is no solution that works on win XP when we put the code in windows service.

Kind Regards

Bharat

您可以简单地使用这两种解决方案，然后根据您使用的 Windows 版本使用适当的解决方案。

使用该System.Environment.OSVersion属性告诉您您使用的是哪个版本的 Windows，然后如果它早于 Windows 7，则执行 CodeProject 解决方案，如果它是 Windows 7 或更高版本，则执行其他解决方案。

您可以在此处阅读有关System.Environment.OSVersion酒店回复您的信息的更多信息。
