Mike,

<< Am I correct in saying I am unable to use EDB unicode with D6 and D7? >>

Correct.

<< Am I able to use EDB ANSI with VS2010? >>

Yes, but only with the EDB ODBC Driver.  .NET managed code is 100% Unicode,
so you won't be able to use the .NET data provider for EDB.

If you have any other questions, please let me know.
