(AutoIt) Cancel Async Task if not Completed after a Max Time

Demonstrates how to wait a maximum amount of time for an asynchronous task to completed. If not completed in the allotted amount of time, the task is cancelled.

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

Local $bSuccess
$oHttp = ObjCreate("Chilkat.Http")

; Set some timeouts, in seconds:
$oHttp.ConnectTimeout = 15
$oHttp.ReadTimeout = 15

; Wait a max time of 2 seconds for the task.
; In this example, it's an unreasonably small amount of time,
; which means the task will get cancelled.
Local $iWaitMaxMs = 2000

; We're just going to download for 2 seconds and then cancel.
; Substitute your own URL with a large enough file for testing..
Local $sDownloadUrl = "http://download.mono-project.com/archive/4.6.1/windows-installer/mono-4.6.1.5-gtksharp-2.12.38-win32-0.msi"

Local $oTask = $oHttp.DownloadAsync($sDownloadUrl,"qa_output/mono.msi")
$oTask.Run()

; Wait a maximum of waitMaxMs for the task (i.e. the HTTP download) to complete.
; The Wait method returns when the task has been canceled, aborted, or completed, or when the max allotted time has passed.
$oTask.Wait($iWaitMaxMs)

; At this point, the download may or may not have completed.  
; Rather than checking the Task status, we can call task.Cancel because
; if the Task is no longer running (because it already completed, was canceled or aborted), then the 
; call to Cancel is a NO-OP (meaning it does nothing and the Task's status is unaffected).
; Also, task.Cancel returns True if the task was in the "queued" or "running" state and was canceled or aborted. 
; The method returns False if the task has any other status.
Local $bWasCanceled = $oTask.Cancel()
If ($bWasCanceled = True) Then
    ConsoleWrite("The HTTP download took too long and was canceled." & @CRLF)

    ; Find out what happened.

        ; with success or failure.  Find out which...
        $bSuccess = $oTask.GetResultBool()
        If ($bSuccess = True) Then
