[Quickfix-developers] application messages

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

I'm still trying to learn FIX and quickfix.  If my broker has custom
application messages, do I subclass the Message class.  I found this
previous message
 * http://permalink.gmane.org/gmane.comp.finance.quickfix.devel/4467

I'm developing in C++ and what I have so far is throwing a validation
error in Message::extractField looking for an = sign in the message.
I'm trying to send this message, not receive it, and I was expecting
the class to build the formatted message for me.  I'm not sure what
I'm missing.

I've written this class:

namespace FIXCQG
{
	class AccountDataRequest : public FIX::Message
	{
	public:
		AccountDataRequest() : Message(MsgType()) {}
		AccountDataRequest(const FIX::Message& m) : Message(m) {}
		~AccountDataRequest() {}
		static FIX::MsgType MsgType() { return FIX::MsgType("UAR"); }

		FIELD_SET(*this, FIX::Account);
		FIELD_SET(*this, FIX::SubscriptionRequestType);
		FIELD_SET(*this, FIX::AcctReqID);
	};
}

I've changed the XML file as follows (psuedo diff syntax, I added the
lines with +)

<messages>
+  <message name='AccountDataRequest' msgcat='app' msgtype='uar'>
+   <field name='Account' required='N' />
+   <field name='SubscriptionRequestType' required='N' />
+   <field name='AcctReqID' required='Y' />
+  </message>
</messages>
<fields>
+  <field number='20003' name='AcctReqID' type='STRING' />
</fields>

Thanks, Doug
