You do not need to manually construct a Logon message.  Session-management
messages (Logon, Logout, Heartbeat, etc) are constructed and sent
automatically by the engine.  Their contents are based on your config file.

You really need to spend more time reading the docs and looking at the
example programs.
Docs: http://www.quickfixengine.org/quickfix/doc/html/
Examples: https://github.com/quickfix/quickfix/tree/master/examples

The config file expects only specific configuration settings.  You can't
just throw any FIX field in there; those will be ignored.  The list of
valid settings is here:
http://www.quickfixengine.org/quickfix/doc/html/configuration.html

In some instances, you may need to insert extra fields in the Logon message
(such as your RawData and RawDataLength params); you can do that via the
toApp() callback.  I don't have a handy C++ example, but here is a C# one
that will be similar:

I'm not sure about SenderSubID.  Hei Chan says it is ignored in the config,
and I don't see it in the list of config settings, so he may be right.
That would surprise me, though, as I know some counterparties use it.  It
might just be missing from the config docs...
