Problems with Iona Orbix 2000 (2.0) + Comet 2000 + VB 6.0 + Callbacks

Hello all,
I ve a strange problem with
Orbix 2000 2.0, Comet 2000, Java Corba Server, Vb-Client and Callback.
If running the VB-Client in Visual Basic IDE everything is working
fine, the
callbacks are executed.
Running outside IDE, the callbacks do not work, COMET writes some
loginformation:

[1c7] IT_Marshall : InvokeDCOMRequest/Dispatch - start
[1c7] Operation name is [[1c7] setMainSelection[1c7] ]
[1c7] IT_Marshall : IT_Param2XXXIter:process
[1c7] start critical section
[1c7] critical section Lock
[1c7] critical section Locked!!
[1c7] critical section UnLock
[1c7] critical section UnLocked!!
[1c7] ---dtor ParamElement List 1, still 1 remaining; address is
27364528
[1c7] ---dtor ParamElement List 0, still 0 remaining; address is
27364624
[1c7] IT_Marshall : InvokeDCOMRequest - Unknown Exception (Possible
GPF)
[1c7] OrbixCOMet error : Marshalling Error, Unknown Exception making
DCOM upcall[1c7] DCOMRequester::invokeRequest[1c7]
[137] 27346944 Release(0) 60 IT_CORBAFactory
[137] 27346944 deleteing... 61 IT_CORBAFactory
[137] -- dec object IT_COMInterface [8] -> [7]
[137] 26647152 Release(0) 62 IT_CORBAFactory
[137] 26647152 deleteing... 63 IT_CORBAFactory
[137] -- dec object IT_COMInterface [7] -> [6]
[137] 26647072 Release(0) 64 IT_ORBObject
[137] 26647072 deleteing... 65 IT_ORBObject

And so on. What is the difference, running in VB IDE and outside as
exe?

Thank you in advance.
Best regards.
Michael

Hi Michael,
Have you been able to get the callback demo that is shipped
with Orbix 2000 to work outside the IDE? If so, have a check
to see if you application is doing anything different to the demo
application.
If this does not solve your problem then send me a mail with more
details of what types your server is sending to the client in the
callback.
  Cheers,
        Paul

Ps.
The correct newsgroup to use for Orbix2000 questions is:
iona.products.orbix2000 and this is available on the
inews.iona.com news server.

1. Orbix 2000 + comet 2000 + VB + Callbacks

hello,
i have the problem, that my software is running if the vb-Client is
executed in the visual basic 6.0 IDE. It can connect to a java corba
server and execute the callbacks. If not running inside VB- running as
exe - the callbacks do not work.
Has anyone an idea why ??

thanx.
michael.
