Import DLL failed

[utilizator]

Hello,
My colleague cannot import the DLL I am sending to him (attached image Import.DLL.failed.png) : "Import failed. etc"

The DLL contains strategies and the custom indicators that the strategies are using(attached image Archive.files.png)

The reference file , AdditionalReferences.txt, has the following content:
System.dll
System.ComponentModel.DataAnnotations.dll
System.Core.dll
System.Net.Http.dll
System.Web.Extensions.dll
System.Windows.Forms.dll
System.Xaml.dll
System.Xml.dll
System.Xml.Linq.dll
Microsoft.CSharp.dll

I see this message when I create the ZIP containing the DLL, CS and
reference TXT (attached image Export.warning.png)

What would be the steps for me to take to track down the issue? Thanks

Hello utilizator,

It appears that you are attempting to add references that are already included in NinjaTrader by default and should not be added to the additionalreferences.txt file.


Also, to confirm, you are sending a .zip file that was exported from NinjaTrader 8, is this correct?

And you have checked the additional references you need within the export window and you have attempted to modify the file manually is this correct?

Is this for NinjaTrader 7 or for NinjaTrader 8?
(NT7 scripts cannot be imported into NT8 and NT8 scripts cannot be imported into NT7)

Hi Chelsea,
My NT is 8.0.14.1 64-bit while my colleague's is 8.0.14.2 64-bit
I exported as DLL and I did not modify the references TXT file that NT8 created.

I recorded the actions I made to create the ZIP, please find the movie at https://app.box.com/s/1ctkkexax2xpqzjz8yv7ooona9adnh5n

How should I do it correctly? thanks

Hi Chelsea,
Also related to this thread:
my colleague would need to remove all custom code from his system before trying to import the DLL I am sending to him.
Besides the folders/Indicators and /Strategies, are there any other places where he should look for custom DLLs and CSs? thanks

[NinjaTrader_ChelseaB]

Hello utilizator,

The majority of those references are not necessary to add.

Can you create a script that calls the same references and indicators with the logic removed and export this so I may analyze the export?

If so, please attach this with your next post.

If not, please send an email to platformsupport [at] ninjatrader [dot] com so that I may request this privately.

[utilizator]

Hi Chelsea,
I removed the logic from indicators and strategies, they do compile OK.
I exported them as CS and DLL(separate ZIPs, of course); please download them from https://app.box.com/s/orboxk8y0ipocld3ssznw96o0g7x9tp9
thanks

Hello utilizator,

From what you have provided, it doesn't look like you need to include any references to dlls at all.

Just check the box for your strategy and try and export. Any open source .cs files the export needs nt should automatically include.

[utilizator]

Hi Chelsea,
When I try to export (DLL or CS) without references, I get an error and the ZIP is not created, please see the attached image and log

However, the CS file in question is named JW_^_retracement.cs while the class inside is named JW_A_retracement. Could this be the reason for this error? If so, what I should rename to what?
thanks

[NinjaTrader_ChelseaB]

Hello utilizator,

I always recommend that the class name match the file name. Not doing so can cause confusion with users who may be importing the script.

Also I recommend not using any special characters that are not underscores (meaning letters and numbers only), and also the class and file name should start with a letter and not a number.

[utilizator]

Hi Chelsea,
I made the change in the files' names. Can you import then now? archives at https://app.box.com/s/i5v3xc9ghcwf8pg9zlocbdrssus05xkz
I am still asked to add NT8 indicators, please see attached image.

Also, in case I want to remove an imported DLL, how should I do that? To what folder the imported DLLs are stored? thanks

[NinjaTrader_ChelseaB]

Hello utilizator,

Yes, the .cs files that are needed are being automatically added with that message. Click Yes.

To remove a third party assembly package please:

• Click Tools -> Remove NinjaScript Assembly...
• Select the assembly to remove -> click the Remove button

To remove open source indicators:

• Click New -> NinjaScript Editor -> select to expand the Indicator folder
• Right-click the indicator by name -> select Remove

To remove an open source strategy:

• Click New -> NinjaScript Editor -> select to expand the Strategies folder
• Right-click the strategy by name -> select Remove

Hi Chelsea,
Thank you for the useful information.

My colleague still could not import my DLL archive, please see his attached screenshots.
Were you able to successfully import my archives on your side? thanks

[NinjaTrader_ChelseaB]

Hello utilizator,

Were you wanting me to test the old ones that have all of the unnecessary references added?

Or did you want me to test the new export you have just created?

[utilizator]

Hi Chelsea,
I mean the latest, with no references and with the corrected file names, https://app.box.com/s/i5v3xc9ghcwf8pg9zlocbdrssus05xkz
thanks

Hello utilizator,

The open source version imported ok. The dll exported did not.

The error I got was:
7/31/2018 12:13:55 PM Default Error compiling import assembly: c:\Users\user\Documents\NinjaTrader 8\bin\Custom\Test.cs(190,45) : error CS0246: The type or namespace name 'instrumentType' could not be found (are you missing a using directive or an assembly reference?)

What error did you get?

Most likely you have added objects to a custom namespace and you are attempting to include the namespace with a using statement instead of using the fully qualified namespace.

If you have done this, remove the using statement and use a fully qualified namespace.
