Question : Relink tables in database with a database password, using ADO

I am converting my DAO code to ADO for a function that relinks tables in a backend database. I have come across one glitch. The backend database has a database password. The code is below. When I try to run this code, it doesn't like the database password line. That is, when Access tries to execute:
     tdf.Properties("Jet OLEDB:Database Password") = strPassword
I get the following error:
     Run-time error '3265';
     Item cannot be found in the collection corresponding to the requested name or ordinal.

The code words fine if I omit the offending line and the database has no password. If I omit the line and the database DOES have a password, I get an "Invalid password" error.

Can I use ADO to relink tables in password-protected databases? If I can, then how do I fix my code?

Answer : Relink tables in database with a database password, using ADO

Why are you changing? You can have ADO and DAO live peacefully side-by-side ...

ADOX tables have different properties. Try something like this instead:

if strPassword <> "" then
  tdf.Name = YourTableName
  Set tdf.ParentCatalog = cat
  tdf.Properties("Jet OLEDB:Link Provider String") = "MS Access;DATABASE=C:\SomeFolder\SomeFile.mdb;Pwd=" & strPassword
  tdf.Properties("Jet OLEDB:Remote Table Name") = tdf.Name
  tdf.Properties("Jet OLDEB:Create Link") = True
  cat.Tables.Append tdf <<< you may not need this
End If
