Hello I am building a simple python app to further educate myself.
I am almost some what complete with this application. However I can
not think how to add more than one entry to a TextBox. So when I input
the first value it stays and then the second value third and so forth
right now it replaces the first value with the second etc etc
You currently have this for setting the text in the textbox:
self.output.Text = str(self.entry_input.Text + "\n")
This replaces the current text with next text. Instead try:
self.output.Text += (self.entry_input.Text + "\n")
No need for the call to str - the Text property of a textbox is already
a string.
All the best,

Here is my app code
#PYTHON#
import clr
clr.AddReference("PresentationFramework")
clr.AddReference("PresentationCore")
from System.IO import File
from System.Windows.Markup import XamlReader
from System.Windows import *
import socket
from threading import *
import cPickle
CMD_MSG = range(1)
class Chat(object):
def __init__(self):
mythread = Thread(target=self.server)
mythread.start()
stream = File.OpenRead("p2pChat.xaml")
self.root = XamlReader.Load(stream)
self.ip_address_input = self.root.FindName('ip_address')
self.sendB = self.root.FindName('send')
self.output = self.root.FindName('textbox')
self.entry_input = self.root.FindName('entry')
self.sendB.Click += self.sendit
def server(self):
self.port = 9000
self.s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
self.s.bind((socket.gethostbyname(socket.gethostname()),
int(self.port)))
#print socket.gethostbyname(socket.gethostname())
while True:
msg, addr = self.s.recvfrom(2024)
## cmd, msg = ord(msg[0]),msg[1:]
## if cmd == CMD_MSG:
self.output.Text = str(msg) + "\n"
def client(self, msg):
self.port = 9000
self.host = self.ip_address_input.Text
self.se <http://self.se> = socket.socket(socket.AF_INET,
socket.SOCK_DGRAM)
self.se.sendto(str(self.host) + " : " + msg, (self.host,
int(self.port)))
def sendit(self, s, e):
self.client(str(self.entry_input.Text))
self.output.Text = str(self.entry_input.Text + "\n")
self.entry_input.Text = ""
myChat = Chat()
app = Application()
app.Run(myChat.root)
Thanks in advance :-)
