I had posted a message here about a client who has a number of databases (Access 97, Oracle 8i, and Sql Server) with system.mda being used for the security. I had asked how to convert the system.mda, but now I find out the client wants to use a .MDE to provide security. I have created .MDEs, but never with Oracle or Sql Server being used for the backend. Can that be done? If so, how?
