vb.net - Unrecognised database format exception -
i have connect programs database.
edit database in access
, , after when running program, error notice unrecognised database format
.
then try make new database , connect vb.net failed again.
don't know fault because didn't change in code.
use provider microsoft.ace.oledb.12.0
, file extension in .accdb
format.
first possibility: database might have been corrupted. try compact , repair.
second possibility: inadvertently database format changed, if case can "save as" lower version 2003 or 2010.
