The best way to invoke function in NinjaScript from external DLL

[alex.nt]

Hi,

Sometimes an indicator has to react on some events in external DLL.

What would be the best way to achieve that?

Polling model, i.e. when each NinjaScript handler like OnBarUpdate calls DLL function to refresh the state can help but a) requires insertion of polling code everywhere b) from the first glance does not look elegant.

Could anyone share their best practice for this?

Thank you.

Alex, which kind of DLL would you be looking to load? .NET compatible (highest target framework 3.5) could be added into the bin > custom folder and then you would reference them directly in the NinjaScript editor (right click > References > Add). NT would load them then upon startup for use...

I am looking for the best practice for DLL ---> script event pumping. Not for a call of DLL function.

I am really disappointed that I cannot link a simple dll!
