Hi there, Can someone please tell how can I set a callback from a web service to a VB6/ActiveX client? I'm using the SoapConnector COM object to communicate with the webservice using SOAP. The web service will automatically send information to the client (via callback) when it needs, and the client has no way to know if the service has data to send. This web service is provided from a 3rd party supplier, and they don't know how can I do this. Thanks for your time. ALMC
