/* 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.
