Answer 1

As far as I can remember, Access can deny you writes despite the fact that database file is writable.

Best way to check it is to try to insert some dummy value right after opening the database. Catch the exception and inform the user.

You can use FileInfo

FileInfo f = new FileInfo(@"C:\MyDb.accdb");
if (f.IsReadOnly)
{
    Console.WriteLine("File is Read only");
}
else
{
    Console.WriteLine("File is Not Read Only");
}
