This page contains sample ADO connection strings for ODBC DSN / DSN-Less,
OLE DB Providers, Remote Data Services (RDS), MS Remote, MS DataShape.
Also included are ADO.NET connection strings for each .NET Managed Provider
(SQLClient, OLEDB, and ODBC).
These sample connection strings are compiled
by Carl Prothman, a Microsoft Visual Basic MVP
Enjoy!

ODBC DSN Connections
Using an ODBC DSN (Data Source Name) is a two step process.
1) You must first create the DSN via the "ODBC Data Source Administrator" program
found in your computer's Control Panel (or Administrative Tools menu in Windows 2000).
Make sure to create a SYSTEM DSN (not a USER DSN) when using ASP.
Note: You can also create the DSN via VB code.
2) Then use the following connection string - with your own DSN name of course. ;-)
ODBC - DSN
Conn.Open "DSN=AdvWorks;" & _
"Uid=Admin;" & _
"Pwd=;
You can also create and use a File DSN. Then use the following ADO Connection string:
ODBC - File DSN
Conn.Open "FILEDSN=c:\somepath\mydb.dsn;" & _
"Uid=Admin;" & _
"Pwd=;"
For more information, see: About ODBC data sources and
How to Use File DSNs and DSN-less Connections
Note: The problem with DSN is that Users can (and will) modify them (or delete by mistake),
then your program won't work so well... So it's better to use a DSN-Less or OLE DB Provider
connection string with a Trusted Connection if possible!
