RE.. [Quickfix-developers] Logon Message ?

[Vamsi K. <Vam...@ib...>]

Hi
I have a situation , where ( can be sequel to John Dahl's requirement),
I need to connect to a database when my login is successful.

	Thereafter I need to share this connection handle across the
other 	functions (onRun and onMessage). I have the following questions
regarding the above situation. Otherwise I would end up having a number
of connection handles for each of the functions( callbacks)

	a) Can I use onRun to periodically generate MarketDataRequest
from the list in the table ( database),( ofcourse it will have where
clause saying if the certain flag is "send" or some thing like that.


There were questions earlier of collection classes, Here is the classic
example,

I need to send a marketdatarequest with certain symbols ( "chose 'CS'
type for simplicity). I would like to use onRun to look into database,
get the symbols and compose the message and send it across.

Now I get a message back ( marketDataSnapshot) with Symbol "A" having
bidprice "12.2".

Before sending I put the symbol in collection class and after I receive
the response ( onMessage),would try to match the symbol and fill up the
prices corresponding to the symbol. Thereafter I will have to update the
information to the database.

My question is How do  we share the collection classes.. across
callbacks and how do we share the connectionhandles..?

It would be nice if the onMessage for admin messages are incorporated.


I guess do we need to update the dictionary for that..?
