13 * SYNOPSIS START
14
15 This sample program demonstrates the cross-platform ODBC database classes
16 donated by the development team at Remstar International.
17
18 The table this sample is based on is developer contact table, and shows
19 some of the simple uses of the database classes wxDb and wxDbTable.
