[V4RB] Opening modified databases

[jda]

Hi Ruslan, a question.

I'm updating database files to a new version (modifying some tables), 
and the schema is updated as well. I have a field 
"MinumumVersionRequired" so that older applications that try to open 
the modified databases can tell the user "This database is too new to 
be opened by this version" (or words to that effect).

The problem is that once I've modified the tables, older versions of 
the application can't open the database at all!  I don't get an error 
message, just

     result = db.open(theFolderItem)

fails.

Therefore, the older version of the application can't access the 
MinimumVersionRequired field.

Am I missing something?

Jon
