[Quickfix-developers] Adding fields to the message

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello Oren:
I am new to quickfix and I am currently exploring it to see if I can use it
in my project. My use case is as follows.

1. Create a session
2. Send a logon request
3. Send a market data request
4. Receive market data and log it to a file

I have modified the tradeClient examples to send the market data request. In
the current version of the Logon.h it doesn't allow me to set the password.
I have modified the code of Logon.h to have an extra method to set the
password. Now, generateLogon method of session is creates a Logon message.
It doesn't set the password field. I can modify that code also and make it
set the password. However, I am wondering if there is a mechanism by which I
don't have to modify the code but just give it some sort of a dictionary to
say here the fields that should be populated for a given message.

TIA.

Please advise.

Cheers,
Amit Khandelwal

Hey Andri,

     Sorry I couldn't be of more help. Wait for another reply from somebody
who is more knowledgable. You can always email Oren Miller (
or...@qu...). I have found that very helpful in the past.

Good luck
Ned

Andrei:
I don't initiate logon message myself. It is initiated by the "Session"
class of QuickFix. Also, the Logon message class is defined in the QuickFix
source code. When you say it is application specific, do you mean to say
that the code outside of QuickFix?

Ned, I have specified the password the configuration file. There are two
issues

1. Logon class doesn't have a method to set(FIELD_SET) for the password
2. generateLogon function inside the Session class doesn't set the password
field on the logon object.

I have modified the code of the Logon class to be able set the password
field. I can modify the code of Session class also to do the same. Just
wanted to check if I am going down the right track or if there is any other
mechanism.
