ABSTRACT:
A first process executing in a computer system creates thread-level message hooks within a second process executing in the computer system. A copy of a global notification hook of the first process is created in the second process. The copy detects a triggering message passed to or from a thread of the second process and determines when and whether to activate a thread-level message hook within the second process; the thread-level message hook is configured to monitor subsequent messages passed to or from the thread of the second process and may take various actions in response to any such messages.
