Sub OpenConnectionX()

Dim wrkODBC As Workspace
Dim conPubs As Connection
Dim conPubs2 As Connection
Dim conPubs3 As Connection
Dim conLoop As Connection

' Create ODBCDirect Workspace object.
Set wrkODBC = CreateWorkspace("NewODBCWorkspace", _
"admin", "", dbUseODBC)

' Open Connection object using supplied information in
' the connect string. If this information were
' insufficient, you could trap for an error rather than
' go to an ODBC Driver Manager dialog box.

MsgBox "Opening Connection1..."
Set conPubs = wrkODBC.OpenConnection("Connection1", _
dbDriverNoPrompt, , _
"ODBC;DATABASE=pubs;UID=sa;PWD=;DSN=Publishers")

' Open read-only Connection object based on information
' you enter in the ODBC Driver Manager dialog box.
MsgBox "Opening Connection2..."
Set conPubs2 = wrkODBC.OpenConnection("Connection2", _
dbDriverPrompt, True, "ODBC;DSN=Publishers;")

' Open read-only Connection object by entering only the

' missing information in the ODBC Driver Manager dialog
' box.
MsgBox "Opening Connection3..."
Set conPubs3 = wrkODBC.OpenConnection("Connection3", _
dbDriverCompleteRequired, True, _
"ODBC;DATABASE=pubs;DSN=Publishers;")

' Enumerate the Connections collection.
For Each conLoop In wrkODBC.Connections
Debug.Print "Connection properties for " & _
conLoop.Name & ":"

With conLoop
' Print property values by explicitly calling each

' Property object; the Connection object does not
' support a Properties collection.
Debug.Print "    Connect = " & .Connect
' Property actually returns a Database object.
Debug.Print "    Database[.Name] = " & _
Database.Name
Debug.Print "    Name = " & .Name
Debug.Print "    QueryTimeout = " & .QueryTimeout
Debug.Print "    RecordsAffected = " & _
RecordsAffected
Debug.Print "    StillExecuting = " & _

StillExecuting
Debug.Print "    Transactions = " & .Transactions
Debug.Print "    Updatable = " & .Updatable
End With

Next conLoop

conPubs.Close
conPubs2.Close
conPubs3.Close
wrkODBC.Close

End Sub


It creates a directworkspace and then opens an connection to a specified database.
