Hi, Woody! If you want to use CORBA and not MIDAS with a CORBA connection, then you need to create and manage your own data transfer protocol - for instance passing records as CORBA data structures on demand. In theory, you could create a TCustomDataSet descendant that would abstract this away so that each CORBA object couild pretend it was dealing with a local data set, but in practice, use of MIDAS would be a lot less expensive that producing that component. The Session / Database / Dataset, except for the illusion provided by MIDAS, is purely local to a specific program (actually to a thread). I'm sorry to not be more help, but I hope this makes it easier to see what you may need to do. ------ Mark Cashman (TeamB - C++ Builder), creator of The Temporal Doorway at http://www.temporaldoorway.com - Original digital art, writing, music and more - C++ Builder / JBuilder Tips and The C++ Builder Programmer's Webring (Join us!) http://www.temporaldoorway.com/programming/index.htm ------
