Hello,
You should always use late binding because only that
backward/forward compatibility is easily maintained
and there is no need to recompile tools that use OLE
each time new version of AB arrives.
That is also the reason why I strongly discourage people
from using type lib (early binding).
Speed is not an issue as OLE in AB is used solely for
large-scale (infrequent) control.
Best regards,
Tomasz Janeczko
