RE: [Quickfix-developers] Problem with VB.NET

Hi Oren,
=20
The FIX works fine and thanks.
=20
I looking for the code snippets to do the following,
=20
1. How to check for a particular session user is already logged on or =
the
connection is alive? ( I see a method isLoggedOn in Acceptor and =
Initiator
classes but not sure how to use in my VB code)
=20
2. How to handle a situation in case of application breakdown (with some
code sample?!) ?=20
=20
3. How can I pass the parameters for SessionSettings from own customized
application (not by using configuration files (*.cfg or whatsoever)?
=20
TIA,
Ramprakash

P.S : The sender is a newbie (to both QuickFix and :NET Technologies) =
and
prefers to have code samples in VB.NET / C#

Ok, I've fixed this and was able to run your sample application with no
problem.  It appears that VB.NET got confused about const pointers that =
were
declared in MC++.  I've attached a new quickfix/src/.NET/Application.h =
file.
If you replace the one you have with this one you should be all set.  =
I'll
check this into CVS and it will be in the next release as well.

Sam, I CC'd you on this because while researching this I noticed you =
posted
the same problem earlier to the mailing list.  Don't know if it is still =
of
interest to you but here is the fix.

Hi All,

I'm a newbie trying to use QuickFix in VB.NET

I ran into problems with my code here. Could anyone of help me to solve. =
I
have seen a similar post with no answers. I use like this in my VB.NET =
code,


Imports QuickFix
Public Class QFapp
   Inherits QuickFix.MessageCracker
   Implements QuickFix.Application

   Public Sub toApp(ByVal msg As QuickFix.Message, ByVal sid As
QuickFix.SessionID) Implements QuickFix.Application.toApp
   End Sub

   Public Sub fromAdmin(ByVal msg As QuickFix.Message, ByVal sid As
QuickFix.SessionID) Implements QuickFix.Application.fromAdmin
   End Sub

   Public Sub onCreate(ByVal sid As QuickFix.SessionID) Implements
QuickFix.Application.onCreate
   End Sub

   Public Sub onLogon(ByVal sid As QuickFix.SessionID) Implements
QuickFix.Application.onLogon
   End Sub

   Public Sub onLogout(ByVal sid As QuickFix.SessionID) Implements
QuickFix.Application.onLogout
   End Sub

   Public Sub toAdmin(ByVal msg As QuickFix.Message, ByVal sid As
QuickFix.SessionID) Implements QuickFix.Application.toAdmin
   End Sub

   Public Sub fromApp(ByVal msg As QuickFix.Message, ByVal sid As
QuickFix.SessionID) Implements QuickFix.Application.fromApp
   End Sub

End Class

And then I call like this,

Imports QuickFix

Module Module1

   Sub Main()

       Try

           'Get Setting from ini file
           Dim ss As New SessionSettings("c:\client.ini")
           Dim sInit As SocketInitiator
           Dim sapp As New QFapp

           Dim storeFactory As New FileStoreFactory(ss)
           Dim logFactory As New FileLogFactory("c:\test.log")
           Dim msgFactory As New DefaultMessageFactory


           'Initiator Section
           sInit =3D New SocketInitiator(sapp, storeFactory, ss, =
msgFactory)
           'sInit =3D New SocketAcceptor(sapp, storeFactory, ss, =
logFactory,
msgFactory)

           sInit.start()

           sInit.stop()





       Catch ex As System.Exception

           Trace.WriteLine(ex.Message)
           Trace.WriteLine(ex.StackTrace)

       End Try

   End Sub

End Module


The System throws an Error (doesn't even caught in Catch Block) with the
following message,


An unhandled exception of type 'System.TypeLoadException' occurred in
Unknown Module.

Additional information: Signature of the body and declaration in a =
method
implementation do not match.  Type: TestFixEngine.QFapp.  Assembly:
TestFixEngine, Version=3D1.0.1605.20104, Culture=3Dneutral, =
PublicKeyToken=3Dnull.

TIA,

Holy


P.S: I could be helpful in anyone of you point out the QuickFix VB.NET
Resources
