MORE INFORMATION

The VersionInfo resource for ODBC.DLL (ODBC Driver Manager) and ODBCCURS.DLL (ODBC Cursor Library) can be viewed using File Manager by selecting the File Menu and choosing Properties.

The property called CursorLevel is a mechanism to guarantee that the right versions of the Driver Manager and Cursor Library are used together. The CursorLevel is not related to any of the ODBC API Levels.

If the CursorLevel of the ODBC Driver Manager is "d" and a Cursor Library with a CursorLevel of "g" is used, the ODBC Driver Manager will not load the Cursor Library. The message from the cursor library is:
