For Standard Security:

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=c:\somepath\mydb.mdb;" & _
           "Uid=admin;" & _
           "Pwd="

If you are using a Workgroup (System database):

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=c:\somepath\mydb.mdb;" & _
           "SystemDB=c:\somepath\mydb.mdw;", _
           "myUsername", "myPassword"

If want to open up the MDB exclusively

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=c:\somepath\mydb.mdb;" & _
           "Exclusive=1;" & _
           "Uid=admin;" & _
           "Pwd="

If MDB is located on a Network Share

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=\\myServer\myShare\myPath\myDb.mdb;" & _
           "Uid=admin;" & _
           "Pwd="

If you don't know the path to the MDB (using ASP)

<%  ' ASP server-side code
oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=" & Server.MapPath(".") & "\myDb.mdb;" & _
           "Uid=admin;" & _
           "Pwd="
%>

This assumes the MDB is in the same directory where the ASP page is running. Also make sure this directory has Write permissions for the user account.
 

If you don't know the path to the MDB (using VB)

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=" & App.Path & "\myDb.mdb;" & _
           "Uid=admin;" & _
           "Pwd="

This assumes the MDB is in the same directory where the application is running.

To connect to a local database (using MyODBC Driver)

oConn.Open "Driver={mySQL};" & _
           "Server=MyServerName;" & _
           "Option=16834;" & _
           "Database=mydb"

To connect to a remote database

oConn.Open "Driver={mySQL};" & _
           "Server=db1.database.com;" & _
           "Port=3306;" & _
           "Option=131072;" & _
           "Stmt=;" & _
           "Database=mydb;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"

To connect to a local database (using MySQL ODBC 3.51 Driver)

oConn.Open "DRIVER={MySQL ODBC 3.51 Driver};" & _
                 "Server=myServerName;" & _
                 "Port=3306;" & _
                 "Option=16384;" & _
                 "Stmt=;" & _
                 "Database=mydatabaseName;" & _
                 "Uid=myUsername;" & _
                 "Pwd=myPassword"

Or

oConn.Open "DRIVER={MySQL ODBC 3.51 Driver};" & _
                 "SERVER=myServerName;" & _
                 "DATABASE=myDatabaseName;" & _
                 "USER=myUsername;" & _
                 "PASSWORD=myPassword;"

Note: When you first install MySQL, it creates a "root" user account (in the sys datbase's user table) with a blank password.

For the current Oracle ODBC Driver from Microsoft

oConn.Open "Driver={Microsoft ODBC for Oracle};" & _
           "Server=OracleServer.world;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"

For the older Oracle ODBC Driver from Microsoft

oConn.Open "Driver={Microsoft ODBC Driver for Oracle};" & _
           "ConnectString=OracleServer.world;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"

oConn.Open "Driver={Oracle ODBC Driver};" & _
           "Dbq=myDBName;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"

Where:  The DBQ name must be defined in the tnsnames.ora file

For Standard Security

oConn.Open "Driver={SQL Server};" & _
           "Server=MyServerName;" & _
           "Database=myDatabaseName;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"

For Trusted Connection security

oConn.Open "Driver={SQL Server};" & _
           "Server=MyServerName;" & _
           "Database=myDatabaseName;" & _
           "Uid=;" & _
           "Pwd="
Or

oConn.Open "Driver={SQL Server};" & _
           "Server=MyServerName;" & _
           "Database=myDatabaseName;" & _
           "Trusted_Connection=yes"

To Prompt user for username and password

oConn.Properties("Prompt") = adPromptAlways
oConn.Open "Driver={SQL Server};" & _
           "Server=MyServerName;" & _
           "DataBase=myDatabaseName"

To connect to SQL Server running on the same computer

oConn.Open "Driver={SQL Server};" & _
           "Server=(local);" & _
           "Database=myDatabaseName;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"

To connect to SQL Server running on a remote computer (via an IP address)

oConn.Open "Driver={SQL Server};" & _
           "Server=xxx.xxx.xxx.xxx;" & _
           "Address=xxx.xxx.xxx.xxx,1433;" & _
           "Network=DBMSSOCN;" & _
           "Database=myDatabaseName;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"

Where:
- xxx.xxx.xxx.xxx is an IP address
- 1433 is the default port number for SQL Server.
- "Network=DBMSSOCN" tells ODBC to use TCP/IP rather than Named
   Pipes
