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. Ruby

require 'chilkat'

success = false

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

socket = Chilkat::CkSocket.new()

# 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() + "\n";
    exit
end

# Start the background thread to run the task.
success = task.Run()
if (!success)
    print task.lastErrorText() + "\n";

    exit
end

# 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)
end

# 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." + "\n";
    print "task status: " + task.status() + "\n";

    exit
end

# 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() + "\n";
else
    print "Connect succeeded." + "\n";
end
