While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

Im trying to create server/client for my GUI design

sinful garnet
#

ok, did you already manage to create some kind of server/client with sockets?
because your question directly goes to sending json between socket connection

valid rivet
#

yeah we were working on it together

#

the server is finished but I dont know how to do the client

and what you want to do next

this is the client

I have no experience with sockets

sinful garnet
#

also you are using @emccue's JSON library

#

and I have no idea how to use it

valid rivet
#

yeah he was helping me but I had to go

sinful garnet
#

but it shouldnt really matter which json library you use

#

also you know how to generally get data in the client from the server right?

wet zenith
#

whats the problem you're having with the client? is it not connecting? is it connecting but data isnt sending?

valid rivet
#

its okay Im just going to go back to regular coding without using json

#

its too confusing for me

sinful garnet
#

but you want to improve right?

valid rivet
#

no I dont have time for this

#

I have only 2 days left

sinful garnet
#

why not taking that step and creating your socket connection using json

sinful garnet
#

are there any requirements for this application or can you just implement your own ideas using the time you have

frosty sleet
#

lol man im still here

#

@sinful garnet For context, their partner did the server code for them

#

but they were sending data in this wackadoodle thing

#

lo%thing#custom<>

valid rivet
#

can you help me more emc?

#

I mean its almost done

frosty sleet
#

sure. give me a few minutes

valid rivet
#

Im just a slow learner

frosty sleet
#

yes

valid rivet
#

very slow 🙂

frosty sleet
#

@sinful garnet hop in vc with us so you see where they are getting lost too

sinful garnet
#

ok but cant talk its almost 2am

frosty sleet
#

oh

#

eh yeah still come

#

@valid rivet in VC

sinful garnet
#

ah ok

#

CodeWithMe literally such a nice feature, used it almost a year ago for helping with javafx and makes many things easier

sinful garnet
#

a bug in your json library?

#

@frosty sleet

#

oof

#

yeah learning/working with libraries without really knowing the language itself is quite hard

sinful garnet
#

bruh my internet just completely died :/

#

so much stuff I have never worked with lol

#

but how are you going to test if it works now though?

#

@frosty sleet

#

gg

glass sorrel
#

So - what is the pushback buffer thing? Or is it gone now so no point?

#

I was doing socket stuff not too long ago and just did the read into a char until < 0.
