Get the LastErrorText for an Asynchronous Method Call

See more Async Examples

Demonstrates how to get the LastErrorText information for a Chilkat method called asynchronously. Chilkat2-Python

import sys
import chilkat2

success = False

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

socket = chilkat2.Socket()

# The Async call simply creates the task.  The "Connect" method has not yet been called.
maxWaitMs = 5000
# Let's intentionally cause this connect to fail by giving it an invalid domain..
# task is a CkTask
task = socket.ConnectAsync("amazonbladflakjsdflksadjf.com",443,True,maxWaitMs)
if (socket.LastMethodSuccess == False):
    print(socket.LastErrorText)
    sys.exit()

# Start the background thread to run the task.
success = task.Run()
if (not success):
    print(task.LastErrorText)

    sys.exit()

# The application is now free to do anything else

# For this example, we'll simply sleep and periodically
# check to see if the Socket Connect if finished.
while task.Finished != True :
    # Sleep 1 ms.
    task.SleepMs(1)

# If the task completed, it means the method (in this case the Connect method) was called and returned success or failure.
if (task.StatusInt != 7):
    print("Task did not complete.")
    print("task status: " + task.Status)

    sys.exit()

# Get the success/failure of the Connect
# (This is the return value of the Connect method had it been called synchronously)
success = task.GetResultBool()
if (success == False):
    # Get the LastErrorText for the Connect method call.
    # Had we called Connect synchronously, we would've simply accessed the socket object's LastErrorText property.
    # Instead, we get the task object's ResultErrorText.
    print(task.ResultErrorText)
else:
    print("Connect succeeded.")
