Hi,
i'm novice to multi-tier application and i would try these expereance.
So i create a little EXE with a form  and a remote data module with a data
set provider control using the wizard.
The CoClass is called DMFastServer and the relative interface is called
IDMFastServer. In this interface i have create a property that return the
value of the status of database connection, called IsDatabaseOpen.
Then i have create my client application that connect with the server using
a socket connection and a client dataset, simulating the server on a remote
machine.
Well, all work fine and i see any data, but i don't know how i can use the
property i have create on server.
What is the source code, on the client application, for use the property in
the interface ?
Is this code reusable also for interface methods ?
I hope my english is not terrible!
Thanks
