/*-------
 * Module:			dlg_specific.c
 *
 * Description:		This module contains any specific code for handling
 *					dialog boxes such as driver/datasource options.  Both the
 *					ConfigDSN() and the SQLDriverConnect() functions use
 *					functions in this module.  If you were to add a new option
 *					to any dialog box, you would most likely only have to change
 *					things in here rather than in 2 separate places as before.
 *
 * Classes:			none
 *
 * API functions:	none
 *
 * Comments:		See "notice.txt" for copyright and license information.
