[Quickfix-developers] Privately defined messages

[Hugo L. <Hug...@in...>]

Hi,

I had to define some private (user defined) messages that have been 
agreeed by both firms. After a bit of work, I got something that works. 
However, I wonder if there is a cleaner way to do this.
The code follows.

Somewhere in "myfields.h":

(...)
	namespace FIX
	{
	USER_DEFINE_STRING(UsrField1, 5000);
	USER_DEFINE_STRING(UsrFiled2, 5001);
	}
(...)
	

Somewhere in "mymessages.h":

(...)
	namespace FIX
	{
	const char MsgType_UsrMessage1[] = "U1";
	}
	
	
	namespace FIX42
	{
		// Had to do this in FIX42 namespace. 
		// User messages defined inside the FIX namespace 
		// always cause an automatic "reject" on receiving, 
		// thereby never reaching crack().
		
	class UsrMessage1 : public Message
	{
	public:
		UsrMessage1() : Message( MsgType() ) {}
		UsrMessage1 ( const Message& m ) : Message( m ) {}
		static FIX::MsgType MsgType() { return FIX::MsgType( 
FIX::MsgType_UsrMessage1 ); }
	
		FIELD_SET( *this, FIX::UsrField1 );
		FIELD_SET( *this, FIX::UsrField2 );
	};
	
	}
(...)


Somewhere in "myfixapplication.cpp" :

(...)
	// Receive user message
	
	void CFixApplication::onMessage (const FIX42::Message& message, 
					const FIX::SessionID& sessionID)
	{								
	
			// Ugly. Had to create this "catch all" to handle 
the user defined messages
			// Maybe there's a cleaner/prettier/better way to 
do this...
	
		FIX::MsgType msgType;
		message.getHeader().getField( msgType );
	
		if (msgType == FIX::MsgType_UsrMessage1)
			onMessage((FIX42::UsrMessage1)message, sessionID);
		else
			throw FIX::UnsupportedMessageType();
	}
	
	void CFixApplication::onMessage (const FIX42::UsrMessage1& 
message, 
					const FIX::SessionID& sessionID)
	{
		// TODO: Proper handling of this message...
		AfxMessageBox ("Got proprietary message UsrMessage1 !");
	}
(...)



Thanks in advance,
