For future reference I was wondering how a series of near duplicate questions from a single user should be handled. At the moment I don't have the rep on SO to do anything but flag questions but the following is the sequence of questions that leads me to ask:
In isolation while not stellar questions they are probably not worthy of flagging. However in combination they clearly all relate to the same piece of code / problem in general so I feel the OP should have left it as a single question and followed up on the various comments / answers made.
At the moment the series of questions seems to have left everyone including myself that tried to contribute confused as to the current state of the problem and what he has / hasn't tried.
