you need to send all of your C#++-- questions to support@xxxxxxxxxxxxx . TJ
doesn't promise that he'll answer all ?'s here. Plus you and the other guy
(Dennis - or are you both the same guy?) are the only ones using that weird
stuff.

Subject: [amibroker] Re: COM and C#
Thomasz,
I got the following code to work when calling the old backtester
(aa.Backtest(2);) but the call to aa.Backtest(0) or aa.Backtest(1)
seems to cause a hang. Do you have any idea what it could be?
---------------------------------
Broker.Application ab = new Broker.ApplicationClass();
Broker.Analysis aa = (Broker.Analysis) ab.Analysis;
ab.LoadDatabase("C:\\Program Files\\AmiBroker\\Data");
Boolean loaded = aa.LoadFormula("c:\\Program
Files\\AmiBroker\\AFL\\CCIopt.afl");
Boolean settingsLoaded = aa.LoadSettings("c:\\Program
Files\\AmiBroker\\AFL\\default.ABS");
aa.ClearFilters();
aa.ApplyTo = 0; // use symbols
aa.RangeMode = 0; // all quotes
aa.Backtest(2);
aa.Export("c:\\temp\\test.csv");
---------------------------------
I would really appreciate it if I got a response on this one. Since
I got everything to work except this last piece.
Thanks,
-David
