Hi,
I'm trying to create an ODBC file DSN.
I get a "file was not saved" error if I try to create it from the ODBC
manager.
I create the file manually
The contents of the file are as follows:
[ODBC]
DRIVER=SAP DB 7.3
ServerNode=localhost
ServerDB=dbname
uid=xxxxx
pwd=xxxxx
IsolationLevel=Committed
SQLMode=ORACLE

I get a reserved error -7778 when connection to this DSN from MSAccess.
How do I create a file DSN?
