+;;; SQLDriverConnect
+;;; [991115 CStacy@Pilgrim.COM]
+;;;
+;;; The CONNX ODBC driver can bring up a nice GUI prompt for the User-ID
+;;; and password, so that applications don't have to supply their own.
+;;;
+;;; That is not desirable for non-interactive applications, such as
+;;; web servers, so they should always supply complete login info
+;;; to SQLConnect. But the driver won't bring up a GUI anyway
+;;; unless the SQL_QUIET_MODE is set to an HWND (nonzero).
+;;; (CONNX version 6 did not have the GUI "Integrated Login" feature,
+;;; and in version 7, it was broken such that the GUI always came up.)
+;;;
+;;; Connx version 8 respects to that connection option, so the first
+;;; thing I tried was just setting it. I hacked the DB-CONNECT ODBC
+;;; method with this:
+;;; (without-error-handling
+;;; (SQLSetConnectOption hdbc $SQL_QUIET_MODE hwnd))
+;;; but that didn't work -- no GUI ever comes up from SQLConnect.
+;;; That may be a bug in the CONNX driver.
+;;;
+;;; In the end, the luser tech support person at CONNX Integrated Solutions
+;;; gave me the hint that if I were using VB, I should give it a string
+;;; like "DSN=CONNX8SAMPLES32, prompt=2". There's no ODBC API that wants
+;;; a string like that, but SQLDriverConnect does take an attribute-value-list
+;;; connection string (including driver-defined attributes). Reading the SDK
+;;; header files, I find that it also takes an argument that is 2 if you want
+;;; the driver to use a GUI and prompt the user. Eureka!
+;;;
+;;; If the user specified a DSN, we use SQL_DRIVER_COMPLETE and let the
+;;; Driver Manager find the appropriate driver. (Otherwise, aside from
+;;; the gratuitous prompt about the driver, the CONNX driver would also
+;;; prompting for the DSN and the Data Dictionary (CDD file).
