Step 17: Create the WSClient Application

WSClient.exe (Web service client) is a console application written in Visual C# that illustrates how to send data to the orchestration that you published as a Web service in the previous steps. The WSClient application accepts four input parameters in order: patient first name, middle name, last name, and social security number, respectively. To send patient information to your Web service, use the following command line syntax:

wsclient john henry smith 123456789  

To create the WSClient application

1. In Solution Explorer, right-click Solution 'BTAHL7V22Common', click Add, and then click New Project.

2. In the Add New Project dialog box, in the Project Types pane, click Visual C# and in the Templates pane, click Console Application.

3. In the Name field, type WSClient. In the Location field, browse to <drive>:\Tutorial, and then click OK. Solution Explorer adds WSClient to the tree, and the Program.cs file appears.

4. In Solution Explorer, right-click WSClient, and then click Add Web Reference.

5. In the Add Web Reference dialog box, click Web services on the local machine. The local computer searches for available Web services, and then displays them in a list.

6. In the list of Web Services on the Local Machine, click BTAHL7_Project_Doorbell_Orchestration_SOAPReceivePort, click Operation_1, and then click Add Reference.

7. Double-click Program.cs.

8. Copy the following code and then paste it into the Program.cs window:

   using System;  
   
   namespace WSClient  
   {  
      class Class1  
      {  
         [STAThread]  
         static void Main(string[] args)  
         {  
            try   
            {  
               localhost.DoorbellRoot req=new WSClient.localhost.DoorbellRoot();  
               req.FirstName=args[0];  
               req.MiddleName=args[1];  
               req.LastName=args[2];  
               req.SSN=args[3];  
               localhost.BTAHL7_Project_Doorbell_Orchestration_SOAPReceivePort sp=new WSClient.localhost.BTAHL7_Project_Doorbell_Orchestration_SOAPReceivePort();  
               sp.Operation_1(req);  
            }  
            catch (Exception ex)  
            {  
               Console.WriteLine(ex.Message);  
            }  
         }  
      }  
   }  
   

9. In Solution Explorer, right-click WSClient, and then click Build. Ensure that a success message appears in the output window. If no success message appears, troubleshoot WSClient. Visual Studio places a copy of the executable, WSClient.exe, into the <drive>:\Tutorial\WSClient\bin\Debug folder.
