You can't do this with Hooks at the moment. Personally I am not happy with the current hook implementation as it does not satisfy what I originally intended it to do. A new hook implementation should come in the next few days, and I'll add the ability to hook notifications as well as messages. The problem is that WM_NOTIFY messages are delivered with an lParam that is a pointer to a structure containing the notification code (like LVN_ENDLABELEDIT). While you can use the current hooks implementation to catch WM_NOTIFY and see the wParam and lParam arguments, the lParam pointer is useless to you in Perl and you can't use Perl to resolve the pointer and get the notification code from it. Watch this space... Steve
