Create another ADO connection for your free table and open a recordset for the free table referencing your new ADO connection.

Are you trying to join the two tables into a single recordset with an SQL query?  If not, declare two connection objects:

dim strConnect as string
dim strSQL as string
dim cn1 as new adodb.connection
dim cn2 as new adodb.connection
dim rs1 as new adodb.recordset
dim rs2 as new adodb.recordset

strConnect = "Connection String for First Connection"
cn1.open strConnect
strConnect = "Connection String for Second Connection"
cn2.open strConnect

strSQL = "SELECT * FROM Table1"
rs1.open strSQL, cn1, adOpenForwardOnly, adLockReadOnly
strSQL = "SELECT * FROM Table2"
rs2.open strSQL, cn2, adOpenForwardOnly, adLockReadOnly

Yes, I am trying to join two tables into a single recordset with an SQL query.
However, one table is a free table(dbf). Another table is in the dbc database.

Any suggestion ???

ADD TABLE Command
Adds a free table to the current database.
ADD TABLE TableName | ?
  [NAME LongTableName]
i'm not sure odbc driver supports this, but you can try:
YourConnection.Execute("ADD TABLE YourTable")

Still looking, but one suggestion is to use an Access MDB and link to the various DBF files.  Set your connection to the .MDB file and query away.  If you want to create this type of setup in code, see http://support.microsoft.com/support/kb/articles/Q230/5/88.ASP?LN=EN-US&SD=gn&FR=0&qry=tables&rnk=15&src=DHCS_MSPSS_gn_SRCH&SPR=ADO
