/*********************************
 * ODBCINST - PROPERTIES
 *********************************
 *
 * PURPOSE:
 *
 * To provide the caller a mechanism to interact with Data Source properties
 * containing Driver specific options while avoiding embedding GUI code in
 * the ODBC infrastructure.
 *
 * DETAILS:
 *
 *	1.	Application calls libodbcinst.ODBCINSTConstructProperties()
 *		- odbcinst will load the driver and call libMyDrvS.ODBCINSTGetProperties() to build a list of all possible properties
 *	2.	Application calls libodbcinst.ODBCINSTSetProperty()
 *		- use, as required, to init values (ie if configuring existing DataSource)
 *		- use libodbcinst.SetConfigMode() & libodbcinst.SQLGetPrivateProfileString() to read existing Data Source info (do not forget to set the mode back)
 *		- do not forget to set mode back to ODBC_BOTH_DSN using SetConfigMode() when done reading
 *		- no call to Driver Setup
 *	3.	Application calls libodbcinst.ODBCINSTValidateProperty()
 *		- use as required (ie on leave widget event)
 *		- an assesment of the entire property list is also done
 *		- this is passed onto the driver setup DLL
 *	4.	Application should refresh widgets in case aPromptData or szValue has changed
 *		- refresh should occur for each property where bRefresh = 1
 *	5.	Application calls libodbcinst.ODBCINSTValidateProperties()
 *		- call this just before saving new Data Source or updating existing Data Source
 *		- should always call this before saving
 *		- use libodbcinst.SetConfigMode() & libodbcinst.SQLWritePrivateProfileString() to save Data Source info
 *		- do not forget to set mode back to ODBC_BOTH_DSN using SetConfigMode() when done saving
 *		- this is passed onto the driver setup DLL
 *	6.	Application calls ODBCINSTDestructProperties() to free up memory
 *		- unload Driver Setup DLL
 *		- frees memory (Driver Setup allocates most of the memory but we free ALL of it in odbcinst)
 *
 * NOTES
 *
 *	1.	odbcinst implements 5 functions to support this GUI config stuff
 *	2.	Driver Setup DLL implements just 3 functions for its share of the work
