* SYNOPSIS START
|
|
|
|
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

|
|
* 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
|
