Hi Chaps I have attempted to purloin some of the code shipped with IP in Action and, following issues, I have even gone to the lengths of reading the book!
I am getting the error 'expect Delegate, got Function' when I use the following code. FYI I am passing in a reference to a WPF textBox so I should have a dispatcher on my UI element I have removed all of the threading pipe reading stuff just to leave 'test' code: import System import System.IO import Avacta.Optim.Server.WebServices import Avacta.Optim.Server.DataModel import sys import clr import time from System import Console from System.Threading import Thread, ThreadStart def SetDispatcher(ui_element): global dispatcher # needed else "Exception: 'NoneType' object has no attribute 'BeginInvoke'" dispatcher = ui_element.Dispatcher def Dispatch(function, *args): dispatcher.BeginInvoke(lambda *_: function(*args)) def GetDispatchFunction(function): return lambda *args: Dispatch(function, *args) class ListOutput: def __init__(self, textbox): self.textbox = textbox def write(self, string): Dispatch(self.addText, string) # error: "expect Delegate, got Function" # self.addText(string) # ok works fine w-w/o dispatcher stuff def addText(self, string): textbox.AppendText(string) if textbox != None: listout = ListOutput(textbox) sys.stdout = listout SetDispatcher(textbox) print "Define running" #running = True Thread.Sleep(0) time.sleep(2) print "Start The Comms Thread..." #comms_t = Thread(ThreadStart(run_comms)) #comms_t.Start() Thread.Sleep(0) time.sleep(2) Any clues would be greatly appreciated!
