relinking tables in Access db using VB.NET and ADOX

Guest

I am trying to relink some Oracle tables in an Access database via VB.NET and ADOX. I receive the following error when executing the cat.ActiveConnection link

"Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another.

Here is my code

Dim cat As ADOX.Catalog = New ADOX.Catalo
Dim tbl As ADOX.Tabl
Dim OracleConn As String = "Provider=MSDAORA.1;Data Source=xzy;User ID=xyz;Password=xyz

Tr
cat.ActiveConnection = "Provider=Microsoft.Jet.OLEDB.4.0;" &
"Data Source=c:\databases\xyz.mdb;" &
"Jet OLEDB:Engine Type=5

For Each tbl In cat.Table
'Check to make sure the table is a linked tabl
If tbl.Type = "LINK" The
tbl.Properties("Jet OLEDB:Create Link").Value = Tru
tbl.Properties("Jet OLEDB:Link Provider String").Value = OracleCon
tbl.Properties("Jet OLEDB:Cache Link Name/Password").Value = Tru
End I
Nex
Catch ex As Exceptio
sr.WriteLine(ex.Message
End Tr

Any ideas

Thank

Hi,

I tryed this once, but after a whiel I gave up: I was able to relink most of
them, but not all, and I didn't found out why not all. If you find it,
please post your code here! I owuld really appreciate it!

This is what I tryed:
Option Explicit On

Probably a connection string issue. Are you using either the Microsoft or Oracle ODBC driver for
your Link Provider String?
