Hello All:


   I tried to do a rather elementary thing - and it has killed my
application.

   I added a TDBISAMSession - and now - my application cant access its data
so it crashes.

   My app is DBISAM Version 1 built in Delphi 5 - so it is a file sharing
application.

   When I attempt to open a file - it crashes with an invalid path to file
error.

   I have a TTable hooked to a database - then hooked to a session.

   I set the session to inactive
   I set the privatedir of the session
   I set the session to active

   I set the TDBISAMDatabase to inactive
   I set the TDBISAMDatabase Directory to the correct location of the data
   I set the TDBISAMDatabase to active

   Then I try to set the Table to active and kaboom I get the error.

   What have I done wrong ???

Hello All:

   After playing around I figured out that I needed to set the session
property of each table.

   This seemed like a huge effort - and an error prone process.

   Since I am not multi-threading access - I decided to use the default
session instead of creating a specific session.

   Therefore, I am now just setting Session.Privatedir

   Is this approach good ???

Thanks

There is no good or bad approach in use default session. You just need to
use a non-default session basically if your application is multi-thread.

To use non-default: Think in this sequence:

1) Session
2) Databases
3) Datasets (tables and queries)

That's what I do in the main thread of my app. OK V4 not V1 but I don't think there should be a problem.

ps: what's it like working with antique software

Thanks everybody,

   Whats it like using antique software ???

   Well - its like driving a classic muscle car - you appreciate the
simplicity and raw power of the beast.
