Did you try to send a message to bot over telegram? Like sending a message to a person?

Hi ergun

Yes I did but it's not working at all.

Do you have any suggestions?

Any help would be much appreciated thanks.

Hi Gwave,

If you already have the project then you can add it as an existing project to your cBot solution and then add it as a reference in your cBot project. Read this post, it could be helpful.

Hi Panagiotis

Thank you very much for that post. It was very helpful. I also ended up " brute forcing" my way to a solution.

Hi Gwave,

Can you provide more information? What is NeuralNet? Did you download/install it somewhere? Why do you expect to see it in the Reference library?

I downloaded original project from GitHub into Visual Studio. Then made some changes to it and now I am trying to implement this on cTrader as the information I have gathered has said it should be possible. Going by your response, I assume I am incorrect? I am not a coder and am just trying to find a solution to a problem. If it's not possible, I understand and appreciate all your help mate.

Hi guys

I am trying to get a NeuralNet to run on cTrader but is this possible at all? I get errors saying I might be missing References, but I can't find them in the Reference library. All the lines of code calling the on the  " using.NeuralNetwork…. " are coming up with the missing reference error.  I can't find a solution anywhere here. Apologies if there is a simple answer to this, i am not a coder. Please help, many thanks.

@Telegram Alert bot stops with "WebException":  05 May 2020, 14:17

Hi guys

I have this Telegram alert bot but everytime I start it, it crashes Onstart with "WebException" please help.

I have both the Channel ID and Key but nothing seems to work.

PS I am not a coder, so please if you could make the solutions relatively simple, I would greatly appreciate it. Many thanks

I have also changed the OnStart solution provide to the one below but still Crashes.

Hi Gwave,

The reason of the problem is described here. Replacing http to https seems to bypass the problem. In case you face this in the future again, have it in mind.
