network packet format?
« on: Aug 26th, 2003, 6:02pm » |

I'm trying to write a client/server app between a C# application and a processing visualization. I can connect the two using standard socket programming, but when I try to send data from the C# app, the p5 app doesn't seem to detect it.
I'm sending straight ASCII bytes to the p5 app, like this:
socket.Send(Encoding.ASCII.GetBytes("SOMETHING"));
but apparently p5 doesn't like it... could someone tell me how network data is formatted in processing?
Cheers,

Ha! I was sending ASCII strings instead of unicode... works lurvely now. Well, it works for 1-byte at-a-time blocks, but I'm sure I'll figure that out.

hmm... is the p5 network stuff using unicode or your .NET stuff was? if it's p5, that sounds like a problem. UTF8 might be ok, but in general most network protocols are gonna be ascii or straight 8-bit binary.

If my .NET sends in ASCII, it doesn't generate a netEvent in P5; if I send in Unicode, it does.
UTF-8 doesn't work either.
Also: I'm guessing that P5 buffers network data until it receives a delimiter, correct? Could you tell me what that delimiter is, so I don't accidentally send it?
I've replicated it for my application by doing this:
Code:String output = "";
String outputBuffer = "";
public void netEvent()
{
if (net != null) {
if(!net.equals("|")) {
outputBuffer = outputBuffer + net;
}
else {
output = outputBuffer;
}
}
}
