Detect a USB device
Hi all,
I just wonder how I can detect a usb drive when it was just inserted to my computer. I really need it since my program will be executed each time when user inserts a usb drive to the system. Thanks.

>>add a handler to WM_DEVICECHANGE message
addition to suggestion of OnegaZhang ....
The system sends the DBT_DEVICEARRIVAL device message when a device has been inserted and becomes available.
To send the DBT_DEVICEARRIVAL device message, the system sends the WM_DEVICECHANGE message with wParam set to DBT_DEVICEARRIVAL and lParam set to the address of a DEV_BROADCAST_HDR structure identifying the device inserted.
dwData = (DWORD) lParam;
But......one problem..
there no provision by this method to detect USB device if its plugged previously or that is plugged in already...
