using: .NET, C#

I have a windows application and within this solution i also have a Webservice.

When a routine in the webservice is called,  I want to display a messagebox to the user informing them that request has come in. In other words I have my Web service "listening" for requests/messages, and when one arrives, I want to inform the User (human) that a request has been receieved.

Any ideas on how to do this would be GREATLY appreciated (dont mean to sound pushy, but Im in kinda of a rush for a solution!)

Thanks
Rad.

For such kind of things usually Remoting is used but you can use it the way described in the first link with web services as well

for remoting see

And why dont you put to show a MessageBox inside the webService when the methos you want to check is called??
You can publish an object dinamicaly with --> RegisterWellKnownServiceType(...)
public class RemoteObject : MarshalByRefObject
{
        private int calls=0;
      //......//
        static RemoteObject ()
      {
            //
            // TODO: Add constructor logic here
            //
      }
      //....//
      public void MethodToCall ()
      {
            calls++;
            System.Windows.Forms.MessageBox.Show("This is the call number:  " + calls.ToString());
      }
}    

Publish this object and when you call to MethodToCall() a messagebox in the server machine will be shown.
