Re: [Quickfix-developers] Custom Logon Message

[Scott K. <sc...@la...>]

Actually, I believe cracking works fine, another way to do this would be:

void MyApplication::toAdmin(FIX::Message& message, const FIX::SessionID&
sessionID)
{
 crack( message, sessionID );
}

void MyApplication::onMessage( FIX42::Logon& message, const FIX::SessionID&
sessionid )
{
message.set(FIX::Username("myusername"));
message.set(FIX::Password("mypassword"));
}

where the MyApplication class extends FIX::Appliaction and
FIX::MessageCracker

This is how to use crack, but I just realized this specific example won't
work because the username and password fields aren't defined for logon
messages by default. (at least in FIX42). This would be the other way:
