If anyone has utilized the client portion of Gerald Lester's Tcl Web Services extension to call .Net web service operations and would be willing to post example code, it would be greatly appreciated. Thanks in advance. Here are specs for a service that I need to call: Web service URL: http://sample/url/WS/OrderTracking.Service.asmx Two web methods: public DHAddress GetOrderShippingAddress(long orderNumber) public bool SetTrackingNumber(long orderNumber, string trackingNumber) Order number to test is: 20071234567 Security is implemented using a SOAP header: OrderTracking_Service wse = new OrderTracking_Service(); AuthHeader auth = new AuthHeader(); auth.Username = "username"; auth.Password = "password"; wse.AuthHeaderValue = auth; .... (make web method call here)
