 | |
| 
 | |
|     This sample program demonstrates the cross-platform ODBC database classes
 | |
|     donated by the development team at Remstar International.
 | |
| 
 | |
|     The table this sample is based on is developer contact table, and shows
 | |
|     some of the simple uses of the database classes wxDB and wxTable.

|  *    To allow each table object (those derived from wxTable) to be

|  *    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
