QUESTION
How do I handle WebSocket
's close and dispose? simple.SubscribeToTicker().Subscribe(...)
needs to be disposed as well.
I saw some people doing it as following, but I'm not sure how Observable.Using(...)
behaves and when it does the disposal.

for the dispose to be triggered when the observable ends.
Here's what that would look like:
QUESTION
I am trying to update a label on my form after I receive a message from an async fired event from another class, and nothing is working so far.
Well, one thing that worked was adding a timer on the main thread that updates the label every 200ms with a public variable from the other class. But there must be an other way.
I tried to use the invoke method, but that didn't work either.
What am I missing/doing wrong?
edit: The function below is called with:
Await SubscribeToWebsocketEvents(creds)

Answered 2020-Dec-09 at 13:28The issue is that you are using the default instance of Form1
on a secondary thread. Default instances are thread-specific so the instance you update is not the instance you have displayed. Read this for more information.
The solution is to invoke a method on the UI thread and then the default instance you use will be the same one you displayed. If you are in a class that is not a form or other control, the way to do that is with the SynchronizationContext
class, e.g.
QUESTION
I have an issue where i use two different WebSocket references. One is a newer version, implementing an extended WebSocket called "SocketIO", the other one just a standard RFC6544 WebSocket. The newer one 'inherited' more or less ages ago parts of the older one but they're not really compatible as of today. For various reasons, i need to be able to use both in the project.
Now if i try them out alone, they work just fine.
If i try them in a project together, i get at the newer one throw an exception:
"Could not load type ... from Assembly.... Version = ... etc".
It apparently searches the assembly of the other Websocket reference for its type and cannot find it.
They don't share identic class names e.g. explicitly naming the reference has no effect and there's also no open conflict marked by VisualStudio.
I've googled around but have not been able to find a solution to e.g. how to tell the program exactly where to look for the newer one's assembly.
Update:
So i looked at the SocketIO Manifest and the exact issue is:
The SocketIO references an old version of the WebSocket4Net
The current version of WebSocket4Net lacks some of these old Types
The problem: SocketIO works just fine without either new or old WebSocket4Net Assembly present - but as soon as a reference is available, it parses that assembly and throws an error that it couldn't find a specific outdated type.
ANSWER
Answered 2020-Jul-24 at 13:28After i burned 4h on this, I circumvented the issue by using a different secondary WebSocket (WebSocketSharp instead of WebSocket4Net); the problem disappeared as WebSocketSharp shares no present/past code with SocketIO as Websocket4Net did.
The core problem that was behind this isn't solved though and i estimate this is a fringe problem, e.g. explicitly assigning or ignoring given external assemblies towards individual types.
QUESTION
I am really having a headache with this weird "issue" with websockets, I am returning to programming from a pause of 10 years and I am learning websockets for the first time, so I must be doing something wrong.
I made a simple code in C# to open a websocket connection and receive messages (Book order updates) from Binance Websocket API, I followed their guidelines like sending a subscribe message in JSON format to be able to receive the messages.
And it works... BUT only if I put a Console.Write("")
in the while loop below, if I don't it just stays in OPEN state and never exits the loop, standing there forever, the command Console.WriteLine("after loop")
is never printed. I put this loop to wait the websocket to connect to the server (State from Connecting to Open).
If you see the code below, With the Console.Write("")
commented the loop is never exited and the websocket messages are never received, uncomment it and everything will work fine.
I attached 2 images showing the output in Console, also tried to take out the "using" statement and put an infinite loop instead of Console.ReadKey();
. But nothing seems to work, only if I uncomment the write command inside the loop, what I think it's bizarre...
Why is this? What am I doing wrong?
...ANSWER
Answered 2020-May-03 at 09:15I was able to reproduce this behavior only in Release
mode and I would say that it seems to be compiler+JIT issue.
