External Dll issue - Accord.net component built on .net 3.5

[ziaul]

I am unable to refer external dll component built on .net framework 3.5. My NT version is 64bit 7.0.1000.18

I can call easily refer my own dll targettted .net framework 3.5 but above external dll that is also built on same environment. I have placed all the component in the specified folder ~\Documents\NinjaTrader 7\bin\Custom.

Please let me know if I am missing something or provide me work around solutions.

Ziaul, what error do you exactly get when trying to reference / load it up?

[ziaul]

I can't get intelligence about the component? Even from Visual Studio I can get all the details about the class.

Please find the attached snaps about my reference components and intelligence issue.

When I try to create component based upon the component description, I get compilation error.

Kindly help me on this?

Regards,
Ziaul

Thanks Ziaul, so you mean the dll loads correctly without error in the log but you're unable to get Intellisense to work as in your VS?

Here's a thread discussing the same item -

Please find the error snaps. It looks like NT can not retrieve 3rd party dll provided by Accord.Net for math, statistics library.

Please check and let me know.

Thanks Ziaul, would closely check if all needed references are actually added as needed - I vaguely recalla a related case with this libary and here AForge.Math was not referenced, so NT could not fully resolve on loading up.

Sorry to open an old thread, but I have this same issue it seems and it is not clear weather there is a solution? Can the Accord math library (Accord.Math and Accord.Statistics) be used or is there a preferred alternative math library that will work with NT7.

It seems from the answers that it is not usable with NT7?

[ziaul]

Accord math library is working fine with me. If you need any assistance, provide me details of your problem. I will try to help you.

Ziaul, your kind offer is helpful, but since my last post I noticed a new Accord version 3.0.2, which apparently integrates the AForge library fully. https://github.com/accord-net/framework/releases After installing this I now am able to see it working with NT7.

Previously when trying to plot my indicator I was getting the popup image you have posted that said "Unable to retrieve type infos from assembly...." Even after making sure I had used the .net v3.5 dll and placed a copy of it in the <My Documents\NinjaTrader 7\bin\custom\> folder, adding it to the "references" in NT7 and including the "using Accord.Statistics" statement in my NT7 code.

Thanks for the advance

Hello jvarela,

Thanks for your post and welcome to the NinjaTrader forums!

Have you added the DLL file address to the NinjaTrader references? You can access the references list through any indicator by editing the indicator and right mouse click on the text and selecting "references".

Hello jvarela,

Thank you for your response.

Are you receiving the same message as detailed in this thread or is your message different when you enable the strategy?

I look forward to your response.
