wxWidgets/demos/dbbrowse/browsedb.h
George Tasker eacf9d88f9 More Unicode support added (though untested and still unfinished).
Changed code to demonstrate the new wxDbConnectInf class
ODBC environment handle now managed via the wxDbConnectInf class
Condensed the use of multiple wxDbConnectInf instances to one and got rid of the bogus EXTERNs of the wxDbConnectInf that were causing so many headaches and mismatched usages of them.
Other minor bug fixes - still have not foudn the reason for the crash on exit

// Pointer to the main database connection used in the program. This
// pointer would normally be used for doing things as database lookups
// for user login names and passwords, getting workstation settings, etc.
// ---> IMPORTANT <---
//
// For each database object created which uses this wxDb pointer
// connection to the database, when a CommitTrans() or RollBackTrans()
// will commit or rollback EVERY object which uses this wxDb pointer.
//
// To allow each table object (those derived from wxDbTable) to be
// individually committed or rolled back, you MUST use a different
// instance of wxDb in the constructor of the table. Doing so creates
// more overhead, and will use more database connections (some DBs have
// connection limits...), so use connections sparringly.
//
// It is recommended that one "main" database connection be created for
// the entire program to use for READ-ONLY database accesses, but for each
// table object which will do a CommitTrans() or RollbackTrans() that a
// new wxDb object be created and used for it.
