An ISAPI extension running under IIS 4.0 gives the following error when
CDatabase::Open is called to open a database connection in an ODBC data
source:
Only SQL_DRIVER_NOPROMPT is allowed when connection pooling is enabled
RESOLUTION
Use the CDatabase::OpenEx function and specify the noOdbcDialog option to
open your database connections.
CDatabase db;
db.OpenEx(_T("DSN=myDS;UID=myID;PWD=myPWD;"), CDatabase::noOdbcDialog);
STATUS
Microsoft is researching this problem and will post new information here in
the Microsoft Knowledge Base as it becomes available.
MORE INFORMATION
The SQL_DRIVER_NOPROMPT flag instructs ODBC to connect with the information
passed in the connect string and to avoid displaying a login dialog box at
run time.
CDatabase::OpenEx() with the noOdbcDialog option calls SQLDriverConnect
with the SQL_DRIVER_NOPROMPT flag. Using the CDatabase::Open function
causes MFC to use SQL_DRIVER_COMPLETE instead of SQL_DRIVER_NOPROMPT.
NOTE: Make sure you are using a "System DSN" and not a "User DSN" with an
ISAPI application. The process for creating a System DSN is identical to
that for creating a regular data source. Open the 32-bit ODBC Administrator
(in the Control Panel) and click the System DSN tab, then click Add to
create a System DataSources.
REFERENCES
Refer to the Visual C++ online help for a complete description of the
OpenEx function.
