[Quickfix-developers] Market Data Request -- dificulties getting a group.

[Ben L. <be...@no...>]

Hi,  I'm trying to grab a group from a market data reply and having issues.

The relevant code is below.  I'm compiling with MSVS 2010 and getting this
error:
error C2664: 'FIX::Message::getGroup' : cannot convert parameter 2 from
'FIX::NoMDEntries' to 'FIX::Group &'

Any help would be greatly appreciated. 

Thanks,
Ben

void Application::onMessage( const FIX42::MarketDataSnapshotFullRefresh&
message, const FIX::SessionID& )
{
	cout << "onMessage: " << message.toString() << endl;
	
	FIX::Symbol symbol;
	message.get(symbol);

	FIX::NoMDEntries noMDEntries;
	message.getGroup(0, noMDEntries);
}

Just realized what I was doing wrong....  Fixed code:

void Application::onMessage( const FIX42::MarketDataSnapshotFullRefresh&
message, const FIX::SessionID& )
{
	cout << "onMessage: " << message.toString() << endl;
	
	FIX::Symbol symbol;
	message.get(symbol);

	FIX42::MarketDataSnapshotFullRefresh::NoMDEntries noMDEntries;
	message.getGroup(0, noMDEntries);
}

FIX::NoMDEntries is a Field class. In order to get the group instance, try:

FIX42::MarketDataSnapshotFullRefresh::NoMDEntries noMDEntries;
message.getGroup(1, noMDEntries);//Indexes are 1-based

Thanks.  Yeah, I'd figured that much out.  I hadn't realized the indexes were
one based, so thanks for that.  I'm not trying to grab a field out of that
group.  I'm doing it this way.  Is there a more fully qualified way to do
it?

FIX::MDEntryType mDEntryType;
noMDEntries.getField(mDEntryType);
