Hi @oleksandr.kocherha

We don't have any C++ Websocket examples as most of our C++ client developers use the RTSDK - specifically the Enterprise Message API - rather than Websocket API.

EMA Consumer - Request & Decode Machine Readable News

Although the above MRN tutorial connects to an ADS, we do have general EMA examples that can connect to RRTO as demonstrated in the QuickStart - Connect to RRTO

Once you work through the RRTO Quickstart and understand how the code for example 113 works, you can merge the 113 Initialisation + session code with the MRN Tutorial code - to achieve your required example.

Hi @oleksandr.kocherha,

I noticed you asked a similar question on this thread.

You state you don't have a locally deployed instance (TREP) you can connect into and you state "RDP doesn't work well". Unfortunately, that doesn't leave you with much left. The language isn't the concern but your requirements of where you want to connect to.

The question is, what do you have access to?

If you have a license to stream data, then you may have access to the OMM-based streaming services. With that, you can utilize the RealTime SDK - C/C++.

I think we need to first establish:

1. What you have access to? What are you licensed to use?
2. Explain what you mean "RDP doesn't work well"?

thanks.

1. I have tried this example in Python https://github.com/Refinitiv-API-Samples/Example.WebSocketAPI.Python.MRN/tree/ERT-in-Cloud and it works I discovered the hostname: emea-3-t1.streaming-pricing-api.refinitiv.com

I have access to Refinitiv Real-Time optimized. I need to read only

MRN_STORY and MRN_TRNA. nothing else.

2. I downloaded and tried some example from a), b)

a)https://github.com/Refinitiv-API-Samples/Example.RDPLibrary.DotNet.MRNStoryConsumer
https://github.com/Refinitiv-API-Samples/Example.RDPLibrary.DotNet/blob/master/src/2.%20Content/2.3-News/2.3.06-News-MRN/2.3.06-News-MRN.cs

b) https://github.com/Refinitiv-API-Samples/Example.RDPLibrary.DotNet

and I cannot make it work, it is not stable. Sometimes I can download something but it generates an exception pretty quickly. I have tried to run both from a computer connected directly to internet and behind a proxy.

Examples of errors:

I always use the same credentials for C# RDP and Python and

only this Python example works for me:

https://github.com/Refinitiv-API-Samples/Example.WebSocketAPI.Python.MRN/tree/ERT-in-Cloud

So I'm looking for the same in C# or in C++

Another error message I have:

One more error message I have:

So as you can see, C#/RDP doesn't work well

So I'm looking to this

https://github.com/Refinitiv-API-Samples/Example.WebSocketAPI.Python.MRN/tree/ERT-in-Cloud

but in C# or if not possible in C++.

I'd like the same simple approach as in Python but in C# (or in C++ if not available in C#)
