RE: Client/Server Applications - what to use?

If you need full control of the connection as well as the application, I
would use a socket connection.  Start by writing a socket service mapper
that will validate the user logon and start a connection to the appropriate
application server.  This can be simple or complex depending on whither you
want to restrict access to IP subnets, computer names, windows user names or
have secure user logon.  Sockets will give you full control of your
environment.  You can even program in keep alive packets to make sure the
client is still available, and free up resources when the client is not
responding.

Subject: Client/Server Applications - what to use?


I have an application to write that I feel would benefit from a graphical,
ie VB5 front end. My question is - what is the best way to link the
application to the as/400....APPC, Data Queues, RDO/VDO, ODBC, etc, etc.
There would need to be a certain amount of validation to be performed on
various input fields, so constant communication between the two is
imperative.  Any ideas or pointers would be appreciated.

Regards
Iain
