    Hi Developers,

              I need ur help .  I am creating  form in  windows control  library. On that I've called a web service by adding reference. It is working very fine. If I drag that windows control library dll (it means by adding this dll into form a a tool)into a windows aplication in the sense, The design of the form appears good in FORM, But the problem is The wes service is not working here, It creates the error "UNABLE TO CONNET REMOTE SERVER". This is my problem. Is ther any other method to call the websevice by using coding not by adding reference

    Thanks in Advance.

    Hi Raju,

    There is another way of calling a web service without adding a reference. But you need to create a proxy object to call that web service. Here's a sample I take from MSDN Library (Communicating with Web Services Asynchronously)

    public class PrimeFactorizer : System.Web.Services.Protocols.SoapHttpClientProtocol {
            public PrimeFactorizer(string strURL) { this.URL = strURL; }
            public long[] Factorize(long factorizableNum) {
                object[] results = this.Invoke("Factorize", new object[] {
                            factorizableNum});
                return ((long[])(results[0]));
            }
           
            public System.IAsyncResult BeginFactorize(long factorizableNum, System.AsyncCallback callback, object asyncState) {
                return this.BeginInvoke("Factorize", new object[] {
                            factorizableNum}, callback, asyncState);
            }
           
            public long[] EndFactorize(System.IAsyncResult asyncResult) {
                object[] results = this.EndInvoke(asyncResult);
                return ((long[])(results[0]));
            }
        }


















    Note that if you created your own web service, it is best to use WSDL.EXE from Visual Studio to generate the proxy object.
