Hello--

I've looked for the answer to this question everywhere I
can think of with no success, and I feel like I'm probably
missing something very simple.

I'm in the early stages of migrating quite a bit of code
from VB6 to VB.NET. In VB6, I was able to create an
ActiveX EXE server that would allow me to maintain
persistent object data, even during periods when no
clients were connected, using global variables in standard
VB modules.

I'm trying to duplicate that functionality in .NET. I
still need COM support for backward compatibiltiy of some
clients. Essentially, I'm looking for a way for a client
to create an object, make changes to soem shared data,
shut down, and then allow another client access to that
same shared data at a later time. Is there a way to do
this in .NET without writing the data out to disk?

Thanks for any insight.

Personally, if I needed to do this, I would look at creating a Windows Service application. Then the clients would connect to the service via remoting. For the COM requirement, I would write a small COM enabled DLL that wrapped the remoting infrastructure to talk to the service.

The advantages to this model is that by having a service, you can set the service handler to restart the application if it errors for some reason, it is always running, and there is a defined interface to your background application.
