Please respond to "Access
Developers discussion and
problem solving"
Thank you. I saw this code on the Access web site. Using the code from the
site:(I am assuming this section)
lngResult = SQLConfigDataSource(0, _
ODBC_ADD_SYS_DSN, _
"SQL Server", _
"DSN=" & JDS_DSN_name & Chr(0) &
_
"Server=" & JDS_Server_name &
Chr(0) & _
"Database=SvCvMarketing" &
Chr(0)
& _
"UseProcForPrepare=Yes" & Chr(0)
& _
"Description=MDTS Database" &
Chr(0) & Chr(0))
How do I add in the User Name and Password?
Thanks Again

Subject: [AccessD] Creating a DSN via code
I have an application that is going to have the backend upsized to SQL
Server 2000. This application sits on about 50 desktops. Would anyone
have
any code examples that I can view to create a DSN connection? The DSN will
have the same username and password for all users so I would like the code
to auto fill the username and password when creating the DSN.
Thank you in advance for all your help.
