Hi

I need to uniquely identify a client application instance at runtime
and pass this value to a Server that processes message from the
client. This value is used to isolate, at the server, different client
instances. The trick is, however, that the method for doing this has
to be somehow backward compatible with a COM+ client.

I'm thinking that if I generate, at runtime, a GUID, and pass that to
the server then that should do the trick. The proviso is here however
that I do that only once per app instance and use the same interface
reference every time. That, I can pretty much guarentee though because
I have development control over the client application. So, how would
I generate a GUID at runtime in .NET (1.1) and COM+ (i.e. V6).

I'm being a little vague I know but to explain the whole concept will
take a while.

Any idea's?

Thanks in advance,
Andrew

Andrew,

To generate a GUID in .NET, use the static
System.Guid.NewGuid() method. In VB6, I think the
suggested idiom is to use the CoCreateGuid method in the
CoCreateGuid API.
