Sorry for this post in this group, but maybe somebody has had the same
problem.
I have a simple VB6 dll registered in COM+, with a hello world public
funtion.

I want only one instance of a Com+ Server Object running and various clients accessing concurrently the same instance.
How can i create this in .Net ?
How can i control the access to tha object's data ?

here is an interesting thing I would like to share. We are using
Framework 1.1. I have about 20 serviced components objects in my COM+
server application, none of them doing heavy stuff on Activate()
stage.

I have a VB6 dll that calls a VB.NET COM+ dll.  The function call requires
passing another VB6 object ByRef.  Everything works as expected in the
function, but when the original VB6 dll finishes and sets the ByRef object
to nothing, there are still activated instances of the ByRef ...

When creating data access components that run as serviced COM+
components i ran into a strange problem.
What happens? I can call methods of my serviced components without any
problems and code executes normally. But for some reason i get following

I tried moving my web application from the development to production server.
Development is running Windows 2000 Advanced Server, production is running

using System.Text;
using System.IO;

I'm developing an ASP.NET application using EnterpriseServices for business

Suppose that a client calls a CAO remote component named C1which in turns
calls into another component C2

string GetProcessID()

I'm trying to pass an object as a parameter to a queued component.  I know
that the class needs to implement the IPersistStream interface, but I'm
still having problems.  First, I'm defining the IPersistStream interface in
my code as follows:

Hi all.  I inherited this code from a contractor.  It is a .NET user
control that runs on the client side (ie) on machines with the
framework installed.  I have been mucking around to get it work for a
couple of days now, and am growign really frustrated.  I need to

This is my first post and apologies for the long message.
I'm having a nightmare trying to get a ServicedComponent
to rollback a transaction that covers the sending of
a message to a Message Queue (local or remote) AND the

We have begun to migrate our applications over to XP....
our components run just fine under 2000...   but when we
put the code on a XP based machine...   and request it

I have written a simple COM+ server application in VB.NET, following all the
guidelines in "Writing Serviced Components" in MSDN.
I only access this COM+ application from another .NET application so I did
not include extra stuff for COM Interop, etc.
