[Quickfix-users] Incorrect BeginString?

[Hei C. <str...@ya...>]

Hi,

I am using the latest quickfix C++ version to connect to a vendor.  The vendor requires the BeginString to be "FIXT.1.1".

If I set BeginString in quickfix's configuration, quickfix will refuse to start since it only supports FIX.4.0-FIX4.4.

If I set BeginString to FIX.4.4 in quickfix's configuration and override the field in toAdmin() and toApp(), when the message comes back from my vendor with BeginString=FIX.1.1, quickfix's Session will kick me out because of "Incorrect BeginString".

I even tried to set UseDataDictionary=N, and I still have the same problem.

Any clean solution?

Thanks in advance.


Cheers,
Hei
