I am using Delphi 1 with Titan and Btrieve. The app I have written works
fine in multi user mode over a Novell Network. However it is important
that my app only works in single user mode.
How can I tell if the app is in use by another station on the Network ?
I am currently flagging a field in a record when the first user logs on
and then resetting the flag when the user logs out. This works fine
because I can check the flag on entry and then quit the app if it is
The problem is that if a crash happens the field could be left flagged
and the nobody would ever get in again.
I am playing with making a table exclusive and checking the results but I
am not having much success with this. Possibly due to a lack of knowledge
on my part.
