Need to detect when a USB drive is inserted.
in [Win32 Kernel]

From: Mike M. on 27 Sep 2005 11:02 Windows XP Pro and Visual Studio 6.0 I need to write a small service that detects when a USB drive is plugged in so I can run another program from the removable drive. I have been testing with the Autoplay settings using TweakUI and such but it isn't as reliable as I would like. And I don't like the way it functions in some circumstances. Is there a way to register to receive the detection event or periodically scan for a device? TIA

The shell provides a less-than-barely documented function named SHNotifyChangeRegister() to register a request to be notified of device or media insertions, removals etc. As it is a shell function, there may be gotchas when trying to use the function in a service which - if you follow reasonable security policy - should not run on the interactive desktop. You may want to post again in the kernel group microsoft.public.win32.programmer.kernel for more information or to see if there are other options. On your way over you may find this sample useful: http://www.codeproject.com/shell/shchangenotifyregister.asp Sadly I couldn't find one the MSDN site. Regards, Will
From: Skywing on 27 Sep 2005 11:49 You could use RegisterDeviceNotification() - lives in user32 (not shell32), well documented, and works for both services and programs that have windows.

From: Mike M. on 27 Sep 2005 14:09 Thanks Will. I'll investigate this method.
