(CkPython) Get the LastErrorText for an Asynchronous Method CallSee more Async ExamplesDemonstrates how to get the LastErrorText information for a Chilkat method called asynchronously.
import sys import chilkat # This example requires the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. socket = chilkat.CkSocket() # 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.get_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.get_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.get_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.") |
