I am working on moving many of our programs over to U3.
U3 (at www.u3.com) is an OS add on that is bundled on various kinds of removable drives
like USB thumb, stick, etc.

I need read only access to tables (for example, classic books, bible..... which we have
been selling for YEARS with DBISAM).

Although I am just starting testing, let me verify that if the tables are marked read only
in the IDE that DBISAM will put it lck files on an available harddrive. If so, is there a
hierarchy? That is, does it try c:\, d:\ etc.?

I also will need to nuke the lck file after the program is over (must, must, must, must,
must, must, must do that- the U3 standard does not permit changing the host system.) Can
someone help me with some code or tips on where the lck file might be and how I can assure
that I have nuked it with extreme prejudice....

Thanks

Herb

If I were to leave the files on the U3 disk and load them into MEMORY does that avoid the
lck issue?

DBISAM will only put the dbisam.lck file in the same directory as the
database tables for a given database.  If it can't create it there, it
automatically treats the the entire database as read-only.

Not really.  Any access to the database directory will cause DBISAM to
attempt to create the dbisam.lck file.
