Good day, For the first time I was trying to create a Db connection with ZODBC Adapter to my MSAccess Db. This was the error displayed when I clicked Add . Invalid connection string: trans hamzat webmaster Traceback (innermost last): File C:\Program Files\WebSite\lib\python\ZPublisher\Publish.py, line 223, in publish_module File C:\Program Files\WebSite\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\Program Files\WebSite\lib\python\Zope\__init__.py, line 226, in zpublisher_exception_hook (Object: LockableItem) File C:\Program Files\WebSite\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\Program Files\WebSite\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_addZODBCConnection) File C:\Program Files\WebSite\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: manage_addZODBCConnection) File C:\Program Files\WebSite\lib\python\Products\ZODBCDA\DA.py, line 104, in manage_addZODBCConnection (Object: LockableItem) File C:\Program Files\WebSite\lib\python\Shared\DC\ZRDB\Connection.py, line 132, in __init__ (Object: RoleManager) File C:\Program Files\WebSite\lib\python\Shared\DC\ZRDB\Connection.py, line 161, in edit (Object: RoleManager) File C:\Program Files\WebSite\lib\python\Shared\DC\ZRDB\Connection.py, line 240, in connect (Object: RoleManager) File C:\Program Files\WebSite\lib\python\Products\ZODBCDA\db.py, line 155, in __init__ BadRequest: (see above) trans -is my specified data source name( the name of my MSaccess Database) hamzat -is my specified user id webmaster -is my specified password. Kindly help to correct what I am doing wrong. Another thing that is not clear to me is that do I have to move the Db to a particular directory in the zope installation directory. Thanks. Kamal
