Unrecognised database format exception

I have already successfully connect my programs to my database.
Then I edit my database in Access, and after that when running my program, I get an error notice that UNRECOGNISED DATABASE FORMAT.

Then I try to make new database and connect to vb.net but it failed again.
I don't know where the fault is because I didn't change anything in my code.
I already use provider Microsoft.ACE.OLEDB.12.0 and file extension in .accdb format.

Solution

  • First possibility: the database might have been corrupted. Try compact and repair.

    Second possibility: inadvertently the database format was changed, if that is the case you can always "save as" a lower version like 2003 or 2010.
