{{Quickfixn}} FromApp not being called Onlogout

Mon Oct 21 11:07:48 PDT 2013

Thanks for all of the responses.  By the way, I made a mistake in my original e-mail.  I meant to say that FromAdmin wasn't being called.

I think what I'm going to do is just send an e-mail when there's a logout and have the e-mail message refer to the log file.  I'd rather take that route than to start changing the source code because then I will not be able to easily upgrade to the next version when it comes out.

Thanks again!!!

I believe Phillip's answer is the correct one.

Some kind of OnDisconnect callback feature has been suggested.  I think someone might even be looking into it.  But we don't have it right now.  I think it would be a very good feature to have.

I don't think QuickFix should call FromApp in this scenario.  FromApp should only be called for incoming valid messages, and in this case, it's not valid.

There's definitely an argument to be made for giving clearer visibility into how the logout was triggered - but that would involve a change to the source code.  I don't see a way to capture the problem scenario you wish to capture with QuickFIX/n as it currently exists (i.e. if you just include it as a dll), but it wouldn't be hard to extend the source code to do what you want.  Download the source code, follow the instructions to build it, and include it in your project.  Update DoTargetTooLow/High in Session.cs to do what additional handling you wish to do.

Hello,

I'm pretty new to QuickFIX.  I'm using version 1.4.0.0 of the QuickFIX.dll in a C# Winforms application.  I want to test what my application will do if the message sequence number that I receive from the server doesn't match the sequence number I'm expecting.  After changing the NextTargetMsgSeqNum on my session, my application logs out and I see 2 messages related to this in the ".event.current.log".

20131021-13<tel:20131021-13>:29:06.435 : Verify failed: MsgSeqNum too low, expecting 20 but received 2
20131021-13<tel:20131021-13>:29:06.437 : Session FIX.4.2:SenderId->TargetId disconnecting: Verify failed: MsgSeqNum too low, expecting 20 but received 2

The problem that I'm having is that the FromApp function isn't being called before OnLogout so I can't capture the message about the sequence number mismatching.  I want to send an e-mail to myself if this situation occurs.

Here's my config:

[DEFAULT]
ConnectionType=initiator
ReconnectInterval=2
FileStorePath=c:\FIX\store
FileLogPath= c:\FIX\log
StartTime=00:00:00
EndTime=00:00:00
UseDataDictionary=Y
DataDictionary= c:\FIX\dictionary\FIX42.xml
SocketConnectHost=127.0.0.1
SocketConnectPort=5000
ResetOnLogon=Y
SendResetSeqNum=Y

# standard config elements

[SESSION]
BeginString=FIX.4.2
SenderCompID=SenderId
TargetCompID=TargetId
HeartBtInt=30

Any help is appreciated.  Thanks for your time!
