I'm using an already existing database for my project, the data types are all set inside the access db, so I get the default DataGridView DataError every time I try to put something different in there. How do I replace the default message with something like 'Wrong data type' (that's the only exception I need to handle). If somebody could be so nice and explain it to me along with the whole 'handling a withevents variable' (I can't get that to work either).
