It does not works
You could add the imports yourself and make it work! ;-) Something like the above should be enough:
<pre><code> import os import sys import datetime from PyQt4.QtGui import * from PyQt4.QtCore import * """Not sure about the use of last variable but it shall work!""" DEFAULT_DAYS_FROM_LAST_AUDIT = 4 </code></pre>
Sorry for the previous message! :$ My Markdown skills are really poor... The code I wrote was:
import sys import os import datetime from PyQt4.QtGui import * from PyQt4.QtCore import * DEFAULT_DAYS_FROM_LAST_AUDIT = 4
That could make it start but there are some more runtime errors on execution. After all it is just an example (a really good one) not something ready for use.
i can't find EventlogParser() anywhere. could you share the code with this class too?
This is a old but very nice example. Thank You
Comments on lines would me more helpful...in all..good code..
