client - server problems with string
Feb 22nd, 2007, 9:13pm  
Hello,
I have strange problem with conection between two applications.
At first server application i send through myServer.write("sentence"). At other client application I recieve this string through myClient.readString().

Everything is working properly, but sometimes there is strange bug with this transition.

Mostly it is receiving normaly
sentence
sentence
sentence

but sometimes it looks like

sent
ence
s
entence
sentence

sentence
...

Please can you help me with it? I think that it is connected with fullfillness of transfering sockets but I dont know how to fix it.

I have WindowsXP Home edition system.

Thanks for your reply.

yep..

As my friend josh nimoy tells me ... "welcome to networking".

I'm not entirely sure myself as I'm also very green in net-coding but I've gotten the same problem as well.

The thing that I did to get around it was to not allow one of the apps (client or server, generally server) to not continue to the next step until all information is recieved properly. You could code some special character or string to represent an "end of line" of sorts.

It also helps if you write a system to lock-step the two although that might be slower.

I also suggest looking into this function:
http://processing.org/reference/libraries/net/Client_readStringUntil_.html

That should at least force a read until you see your end-line character, then strip the character out and you have a proper response.
