Trying to VerifyVendorLicense in Constructor in my class

[KhaosTrader]

Hi,

I have a class that I put in an Addon...

I want to call the VerfiyVendorLicense in the constructor, but I am having no luck..

here is psuedocode to illustrate my non-working attempt

public class WorkerAx1
{
public WorkerAx1(Indicator Indicator)
		{
			
			(NinjaScript)Indicator.VerifyVendorLicense("MyVendorLicense", "productname", "website", "email");
...
...
...
}

... functions and such...

}

Please tell me how to do this correctly.

Thanks in advance.

Hello KhaosTrader,

Adding the vendor licensing to the constructor of the Addon would be correct.

This doesn't appear to be its own actual addon but just a custom class, however.

Are you receiving an error message?

If so, what is the error message?

Below is link to a sample starter addon.

it is just a custom class, yes...

actually i want to call VendorLicense

I am getting error..... --> NinjaTrader.Cbi.VendorLicense is a "type" but is used like a variable...


i did try to put this in the constructor of my class but got an error...

	VendorLicense  vl = new VendorLicense("VendorName", "ProductName", "website", "email");

I got an error stating no constructor has 4 arguments..

I am not sure how to use VendorLicense this way,, as when I use in the indicator I just put this line by itself and it works..

 VendorLicense("VendorName", "ProductName", "website", "email");

Hi KhaosTrader,

Oh I see now:

(NinjaScript)Indicator.VerifyVendorLicense

This is not going work.

The NinjaTrader.VendorLicense class appears protected. I'm inquiring with our development to find out more.

I appreciate your patience.

Ok Standing by... Hopefully you can figure out a workaround or something..

Hi KhaosTrader,

I haven't gotten a why on this yet, but.. the custom class is going to have to extend the AddonBase (or NinjaScriptBase). There doesn't seem to be a way around it.

So, you can create a helper class that extends the AddonBase, and then create an instance of this class in your custom class, and use this instance to call VendorLicense().

Michael in our product management modified one of my simple examples to add this in there.

Hi Chelsea,

With the help of your AddOn I was able to integrate vendor license verification in my add-on.
But how can I get and analyze the result of the license verification?
I'd like to restrict to simulation accounts during free trials.

Hello ruppschtaler,

Unfortunately, this information is not provided.

Either the VendorLicense verifies or it does not. There are no properties returned that tell if verified due to trial and does not provide a property that shows when a purchased license will expire.

Hello Chelsea,

I think it's crucial to know if a trial or a purchased license has been verified and would like to request this feature.

Thanks in advance!

Hello ruppschtaler,

I've received a tracking ID for your request.

Your request for the VendorLicense() method to return the license type to be trial or full is being tracked with ID #SFT-3125.

Please note it is up to the NinjaTrader Development to consider if and when a request will be implemented.

Thank you for your feedback. Please let me know of any other suggestions you have for the NinjaTrader platform.
