NinjaTrader.Client.dlll v.8.0.28.0

[Atomic]

We built a dll to allow Tradestation to work with Ninjatrader using the NinjaTrader.Client.dll instead of the NtDirect.dll that we had been using. Today, for a different reason, I upgraded to v.8.0.28.0 from 8.0.26.1. The dll no long worked, so I rebuilt the solution in VS using the file "C:\Program Files\NinjaTrader 8\bin\NinjaTrader.Client.tlb". The dll builds ok, when I try to call it from Easylanguage, I get a C++ exception, which I suspect is due to the fact that the dll I build using that file is 64 bit, which may not work with Tradestation. Can anyone comment?

As a check on what is going on I went to a different computer which has NT 8.0.27.1 on it and I took all of my dlls which were designed as a wrapper for the NinjaTrader.Client.dll and tested them and they all worked using the exact same dll call. If they do not work which I am using NT 8.0.28.0, does that mean the NinjaTrader.Client.dll has changed, or something else?

If I have a dll that works with NinjaTrader.Client.dll on v 8.0.26 or 27 is it reasonable to expect that it would also work with v 8.0.28 or 8.1, but it doesn't. Please explain.

Got any screenshots?

Got any screenshots?

The error message simply says C++ exception. There is no other information.


The Easylanguage scriptd that is running is this:

DefineDLLFunc: "TsDllTester.dll", string, "NewOrderId";

once begin
print(NewOrderId);
end;​

The same code with the same dll works on v8.0.27, but fails on v8.0.28.

Here's another piece of information. When I go to a server that is running Tradestation 10(68) and NinjaTrader 8.0.28.x, then dll wokrs fine. When I try to use the same dll on my own desktop, it fails with C++ exception. Any ideas on this?

Hello Atomic,

You may want to reinstall.

I've tested the NinjaTrader.Client.dll on 8.1.1.7 and this is working without issue.

An example project to test with can be found here.

Thank you. I will try 8.1.1.7 tomorrow. What I see right now is that on my windows 11 desktop, my dll will not work with NT v8.1, but it does work with NTv8.0.26 or NTv8.0.27.
The dll also works on Windows server version 2019 with NTv8.1.x. Go figure...

Can you tell me if the .Net versions are the same for NTv8.0.27 and NTv8.0.28 and NTv8.1.1?

Hello Atomic,

Both versions use .NET 4.8, which was updated in release 8.0.23.2.
