Duh! I guess I did not realize that I did not need the dbexpress controls. I kept looking for a way to include the postgres in the SQLConnection control. From what you said the Zeos controls are almost direct replacements? So I can use the Zeos (dbExpress) controls to make the connection and then use the standard data-aware controls to use the data i.e. DBGrid. Is there something I'm supposed to change in a property or event within DBGrid so it would use the Zeos controls? I think I also have a Zeos controls directory. I don't recall what is in the directory. Is it possible that what ever is in the directory is a replacement for the standard data-aware controls? Of course I'm just attempting prevent the same error I made with dbExpress.

On another note: I just finished a book on postgres. I'm very jazzed about the ability to add programming to the database. But of course it's another language to learn. I wonder if there is a Delphi to postgres language yet? When I decided that I was going to use postgres I stopped reading about Delphi and started reading about postgres. This of course got me into the heart of Linux and the setup for postgres. I'm very glad I did the research but it has taken time. But now I need to understand Delphi much better. I can get very simple demo programs from the Delphi book to work. But I need to understand the procedures required to get to the postgres data.
