Re: [Quickfix-developers] application messages

[Doug a. M. G. <dou...@gm...>]

I found a few more references:

http://old.nabble.com/Adding-Custom-Message-to-Fix42.xml-and-handling-in-application-td22242307.html
http://old.nabble.com/Custom-Messages-Classes-Tutorial-td13495584.html

I haven't worked through it yet, but this looks like a good start.  If
I read it right, then it sounds like I need to add these messages to
quickfix instead of to my application and rebuild quickfix.  Does that
sound right?
