I don't have any idea where to start to access system file objects and change their property attributes. Using ADO, I am reading data from an Access DB file. Immediately after the read, I want to lock the database (ie change its property attribute to read-only) so others cannot make changes to the database while my program processes the data.
When the data is computed, I would like to return the database to its default state of read-write.

I'm guessing this is very difficult, but trying to find this info in the MSDN Library is like looking for a needle in a haystack.

Please help.

Thanks,
