Default Unrecognised database format - 08-07-2005 , 06:01 AM






I wrote a database appllication that was initially used in the office
by me and one person

Now four of us use (maybe maximum of 3 at once) it but sometimes I get
the message

Unrecognised database format

Which means the database has crashed ie when closed it cannot be
reopened (it still shows the ldb file as active)

We use office 2000 and Access 2000

I have a utility program which will fix it again but it is still a
nuisance

Anyone come across this problem

You need to "split" your database so that everyone has his/her own copy of
the front end ....

See these articles for more info about splitting a database:

Thanks Ken

I'm trying to digest that

opening forms

Will keep reading the link stuff

You can speed up the forms if you open and maintain a persistent connection
to the backend database. I do this in the "splash screen" form (my "startup"
form) by running code in its Timer event that opens a hidden form that is
based on a dummy table in the backend. This maintains a persistent
connection so that the front end does not need to continually test and
delete and open an . ldb file for the backend for that front end.

Thanks Ken

I have been having trouble sending a reply - as you can see
I'll try again but what I am trying to say is that this is a bit too
technical for me

I saw that reply, and assumed that you were not going to pursue the concept.
Perhaps I misunderstood, and you want to continue with this suggestion?
