问题
I am trying to open a Connection to Password protected AccessDB, through Excel VBA.
I am using the following connection string
conn.Provider = "Microsoft.ACE.OLEDB.12.0"
conn.ConnectionString = "Data Source=dbPath; Jet OLEDB:Database Password=pwd;"
where dbPath is the path of accdb/mdb file and pwd is the password to the dbfile. The password is absolutely correct but I am always getting the error "Not a Valid Password". Could someone please guide me in this?? -Sri.
Additional Info: I am using office 2010 and saved this database as mdb(2003) file(I tried saving this file with accdb extn also). When i am trying to set a password to the database, it shows the msg "Encrypting with a block cipher is incompatible with row level locking. Row level locking will be ignored." Does it have anything to do with the error msg in VBA?
回答1:
In Access 2010 the encryption method changed for database passwords, and the ADO provider's "Jet OLEDB:Database Password" keyword does not appear to work with the new method. Here, I had to remove the password, go into Access->File->Options->Client Settings->Advanced and check "use legacy encryption", then recreate the password.
I do not know if there are any new OLE DB connection string keywords for the ACE provider or whether this problem also occurs when using ADO.NET

Or you could do this.
conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & dbPath & ";Jet OLEDB:Database Password=" & pwd
