COM with Borland RAD C++ 2007 problem

[second]

Tried to use COM with Borland RAD C++ 2007. Made new package with NinjaTrder Client, got NinjaTrader_Client_OCX.h, NinjaTrader_Client_TLB.h generated and new visual components on ToolPalette: TClient, TQueryInstrument, TCore.
When I make an instance of TClient, I got available few functions only: Connect(), Disconnect() and some other concerning to COM interface,
but there is not data and trade functions like: SubscribeMarketData, MarketData, etc.
What should I do to get them, please?

Attached generated files.

Unfortunately we are no Borland experts. Thus we would not know what causes the issues you experience.

Here is a list of functions which should be available as the COM level: http://www.ninjatrader-support.com/H...unctions3.html

Note: we are aware that some customers experience oddities using the COM interface, which we haven't been able to isolate/resolve. As an alternative you could try the DLL interface:

Thanks, DLL seems to me works, but could not retrive MarketData for ES 12-09 futures. I got "0" in all cases.
I guess I might be wrong in instrument name.
What name should I type for "ES 12-09" in string instrument argument?
double MarketData(string instrument, int type)

"ES 12-09" is correct. Note: exchanges are closed right now -> you will not get any realtime market data. Please try again tomorrow as exchanges are open.

Oh, thanks. I guess that's it, but looked at Friday chart and thought last price will be friday close price. Thank you for your help.

Great, I got market data, but had one strange thing:
int Connected(int showMessage) allways returns "-1" i.e. no connection,
even when I'm getting data. What's wrong?

Sorry, I would not know. I suggest debugging your application.

I just tested again the C# sample application we provide in folder <install>/NinjaTradre6.5/bin/AutoTrade. It works as expected and client.Connected(0) would return 0. That sample application might be a good starter for you endeavor.
