Re: [Quickfix-developers] Logon passwords

[Vincent P. <vpr...@ph...>]

I'm going to move my password checking out of the fromAdmin method to  
the overloaded onMessage methods for each message to be  
authenticated, like this:  This will move password checking down from  
the session level to the message level.

void QFApplication::onMessage(const FIX44::NewOrderSingle& m, const  
SessionID    & id)
{
	Password pwd;   m.getField(pwd);
    	if(pwd.getString() != string(dbpwd))   throw FIX::RejectLogon();
}

Then on the sender side, I have this:

	FIX44::NewOrderSingle o(...);
	o.setField(FIX::Password("x0x0x0");
	FIX::Session::sendToTarget(o);

This compiles, but when it runs, I get this stuff on the acceptor side:

<20080617-16:20:57, FIX.4.4:MP->CLIENT, incoming>
   (8=FIX. 
4.49=15035=D34=158249=CLIENT52=20080617-16:20:38.99156=MP1=314411=158138

   (Message 1582 Rejected: Tag not defined for this message type:554)
