Re: [Quickfix-developers] Attempted to read or write protected memory.This is often an indication that other memory is corrupt.

[BRACKLEY, A. G. <And...@rb...>]

I'm fairly new to quickfix so could be wrong but I don't think getField(xxx) populates the field you pass it.  Instead it returns the field details which you are interested in.  The parameter is simply so that it can recognize the correct field type you are interested in.

Therefore you probably need something like:

QuickFix.Message qfmsg = qMessages.Dequeue() as QuickFix.Message;
QuickFix.MsgType qfmsgtype_tag = new MsgType();

QuickFix.MsgType qfmsgtype qfmsgtype = qfmsg.getHeader().getField(qfmsgtype_tag);
strMsgType = qfmsgtype.getValue();

Hope this helps
