What API function can get the message about the hardware plug and pull out event?

Hi Allistar,
Thanks for your reply.
We are using the ikey which is like watchdog. When it is plugged, then our software will read and verify its security information which mainly are user name and password. User will not entry the user name and password to log on our software instead of it. After it is pull out, software will be shut down automatically.
Can you have any suggestion about it?

It seems that this is a USB device. You'll need to write an application (most likely not in JADE) that detects when the device has been removed. There should be a system event that is broadcast when this happens, or alternatively you could periodically pool the device to make sure it is still there.

I doubt you'll be able to detect the removal of this device using JADE alone. Most likely some lower level C++ code is required.

Regards,
Allistar.

I know most likely some lower level C++ code is required, so I want to know what API(application programming interface) function can do it.

Try looking at the device management section on MSDN and RegisterDeviceNotification. It looks like a windows message is sent.

It would be nice if there was a mechanism to register for certain windows messages in Jade perhaps with a call back function.
