(Unicode C) Asynchronous HTTP SOAP 1.2 Request and Response using POSTDemonstrates 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.

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.
