I have a VB.NET windows application that is talking to an Access 2003 Database. While I was initially developing the application (2 months ago), I kept getting this pesky OleDbException (Cannot open databae ''. It may not be a database that your application recognizes, or the file may be corrupt.) After some googling, I converted the database to Access 2003 (had been in Access 2000) and the error seemed to go away. Now it's back! It's an intermittent error that just seems to pop up at different spots in the application. Has anyone else seen this exception before? Any suggestions as to what I can do? I have posted this to the VB.NET forum as well.
