Re: [amibroker] Re: 2 Instances of Quotetracker with AB?

["Tomasz Janeczko" <amibroker@xxxxxx>]

Hello,

I understand what you mean but in Microsoft's OLE mechanism
(when declaring class factory) you have the choice to allow or not to
allow multiple instantiation. There is no "third" option.
For this reason, implementing your idea would also force the creation of new instance 
via each call to CreateObject and this would break many existing applications 
and formulas relaying on  current CreateObject behaviour 
(including AmiQuote, PowerScan and all other scripts using AB object).

Best regards,
Tomasz Janeczko
