problem of monitoring directory

[shenoubang <oubang@xxxxxxx>]

Dear everyone:
    I am very sorry to trouble you, but I can not handle a problem about my program for a long time, I hope someone can help me, thank you very much!
     The program is to monitor directories and report the events occoured in directory shuch as deleting files , creating files and so on. My program can monitor the directory and its child diectroy, and report the event that happened on a single file or directory, but it can only monitor the toppest directory and do not report the events when copy diredtory which contains many files.
   My code is in attachment, I would appreciate very much if someone help me to handle this problem, thank you very much!
