Hi!
The only disadvantages is a bit larger code size and data segment. Some
hidden virtual methods are added to all your classes, with a bit of
constant data. Be very careful when your app runs without globals.
Besides that it works perfectly.

What is the best way to lock the code resource? I have a background app

I thought that protecting the database with DmDatabaseProtect would only
prevent the database from beeing deleted (and broadcast a

A while ago I looked at the "help widget" of FLTK. It can render basic

Hi!
I would suggest packing in larger records (like others have suggested),
and then use your own binary search to find your record (assuming of
course they are pre-sorted). If your data is read-only and all records
have the same size this is not difficult to implement.
good luck.
