Hi,
after trying and despairing a lot of hours I found out the problem. The
problem was not the precision of numbers or something else. The problem was
that several fields of the Access Database had set up a standard value and
after an insert the field becomes the standard value if the field is empty.
If you didn�t refresh the table and try to update such row the provider
tries to find the row with the fields you gave a pfinwhere. And now the
provider didn�t find the row because some fields had become values. I never
had thought of something like this because I always set up my own Databases
and never used standard values. But this time I got a Database to work with.
Argghh this is very annoying

But now it works thanks!
