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 * *********************************/ #define ODBCINST_SUCCESS 0 #define ODBCINST_WARNING 1 #define ODBCINST_ERROR 2 #define ODBCINST_PROMPTTYPE_LABEL 0 /* readonly */ #define ODBCINST_PROMPTTYPE_TEXTEDIT 1 #define ODBCINST_PROMPTTYPE_LISTBOX 2 #define ODBCINST_PROMPTTYPE_COMBOBOX 3 #define ODBCINST_PROMPTTYPE_FILENAME 4 #define ODBCINST_PROMPTTYPE_HIDDEN 5 #define ODBCINST_PROMPTTYPE_TEXTEDIT_PASSWORD 6 typedef struct tODBCINSTPROPERTY { struct tODBCINSTPROPERTY *pNext; /* pointer to next property, NULL if last property */ char szName[INI_MAX_PROPERTY_NAME+1]; /* property name */ char szValue[INI_MAX_PROPERTY_VALUE+1]; /* property value */ int nPromptType; /* PROMPTTYPE_TEXTEDIT, PROMPTTYPE_LISTBOX, PROMPTTYPE_COMBOBOX, PROMPTTYPE_FILENAME */ char **aPromptData; /* array of pointers terminated with a NULL value in array. */ char *pszHelp; /* help on this property (driver setups should keep it short) */ void *pWidget; /* CALLER CAN STORE A POINTER TO ?
