I'm trying to make some kind of bridge between Ninja and another application using DDE for that I'm using the attached free library but Ninja throw the following message, any one have an idea how to fix it?


Failed to execute DB job 'StrategyUpdateJob': There was an error reflecting type 'NinjaTrader.Strategy._Bridge'.: Cannot serialize member 'NinjaTrader.Strategy._Bridge.TheDdeClient' of type 'NDde.Client.DdeClient', see inner exception for more details.: NDde.Client.DdeClient cannot be serialized because it does not have a parameterless constructor.

You have to implement a default constructor

public DdeClient()
{
}

because of Serilalization

why dde, its old and slow.

Well really not an expert and no formal programming foundations, but if you can show me the path for a better solution I will be a happy camper, it doesn't have to be DDE, I just found it and think of it as a possible option.

dde was fine 4 using matlab. here a russian page Using MATLAB as a Client :: COM and DDE Support (Windows Only) (External Interfaces)

but you can use for net interop COM Interop Part 1: C# Client Tutorial (C#)

and an example to call excel from c# with interop https://msdn.microsoft.com/en-us/library/ms173186%28VS.80%29.aspx

best regards

also possible tcp/ip client server communication ...
