Hello all,

I am developping a software whitch store image(Jpeg) with some information
on a record.
A program can view a imges with information and edit them. So that it need
to lock the record while viewing the image to avoid to modify the same
record form another network cleint program.

Please advise how to lock a record and check a record is locked or not.
