Register Class as Single-Instance

hi.

im creating com class in vb ( in activeExe project),

then i call from clientVB to the CreateObject method.


my q.

how can i be make sure the im getting a reference to
the same COM CLASS if i using 2 clients.

i know i need to use GetObject ,but i read that i also
need to register my class as SINGLE-INSTANCE, and then

CreateObject will Always return the same object reference.

thanks, and goodbye.
