Asynchronous HTTP SOAP 1.2 Request and Response using POST
Demonstrates a working asynchronous SOAP 1.2 request and response using POST with a live server. You may try running this example with the URLs and data provided. See http://wsf.cdyne.com/WeatherWS/Weather.asmx?op=GetCityWeatherByZIP for details.Note: This example is correct in theory, but no longer works for live testing because the SOAP service provider (cdyne.com) has made changes or discontinued the free service.

// If the task was "canceled", it was canceled prior to actually starting. This could
// happen if the task was canceled while waiting in a thread pool queue to be scheduled by Chilkat's
// background thread pool scheduler.
// If the task was "aborted", it indicates that it was canceled while running in a background thread.
// The ResultErrorText will likely indicate that the task was aborted.
// If the task "completed", then it ran to completion, but the actual success/failure of the method
// is determined by the result obtained via a GetResult* method. (A "completed" task will
// have a StatusInt equal to 7. If the task finished, but was not completed, then it must've
// been aborted or canceled:

// The application is now free to do anything else

// -------------------------------------------------------------------------------
// The following is a general note that applies to all programming languages:
// -------------------------------------------------------------------------------
// NOTE: This is very important: The TaskCompleted callback runs in the background thread.
// (All callbacks from an async task, such as AbortCheck, PercentDone, ProgressInfo, etc. are in the background thread.)
// An application that uses TaskCompleted must be very careful.
// For example, user interface elements (such as labels, text boxes, etc.) may not be directly
// accessible from a background thread, and could crash the application if directly accessed. Also, attempting to debug
// code running in a background thread from an IDE, especially an older IDE (such as VB6) is likely to crash the IDE.
