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

$socket = New-Object Chilkat.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 = $socket.ConnectAsync("amazonbladflakjsdflksadjf.com",443,$true,$maxWaitMs)
if ($socket.LastMethodSuccess -eq $false) {
    $($socket.LastErrorText)
    exit
}

# Start the background thread to run the task.
$success = $task.Run()
if (!$success) {
    $($task.LastErrorText)

    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 -ne $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 -ne 7) {
    $("Task did not complete.")
    $("task status: " + $task.Status)

    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 -eq $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.
    $($task.ResultErrorText)
}

    $("Connect succeeded.")
