SYMPTOMS
When you use ActiveX Data Objects (ADO) and ODBC to try to connect to a Microsoft Access database, you may receive the following error message:
CAUSE
This error message occurs because you do not have the correct permissions to create the lock file (.ldb) for a Microsoft Access database. By default, a lock file is created in the same folder as the Microsoft Access .mdb file.
RESOLUTION
To resolve this problem, follow these steps:
- Grant the user who is accessing the database (usually the IUSR_<computername> account) full control to the share or folder.
Sometimes permissions are restricted on the share because the file is intended to be read-only. You may want to try to change the connection mode, which the following code demonstrates:
Set Conn = Server.CreateObject("ADODB.Connection") Conn.Mode = adModeShareDenyWrite '8 'From Adovbs.inc '---- ConnectModeEnum Values ---- 'Const adModeUnknown = 0 'Const adModeRead = 1 'Const adModeWrite = 2 'Const adModeReadWrite = 3 'Const adModeShareDenyRead = 4 'Const adModeShareDenyWrite = 8 'Const adModeShareExclusive = &Hc 'Const adModeShareDenyNone = &H10
STATUS
This behavior is by design.
