16.1.2. Add Web Reference

In the Add Web Reference window, users can create a new web reference for the application.

*These references enable communication between the DBP workflow management system and other systems in the code environment, facilitating the efficient transfer of information between interconnected systems.

1. Address Bar: This field allows users to input the address or URL of the desired web service.
   
   • Back: This button allows users to navigate back to the previously visited web address.
   • Forward: This button allows users to move forward in their browsing history, if they have previously gone back.
   • Refresh: This button allows users to reload the current web page.
   • Stop: This button allows users to halt the loading process of the current web page.
   • Go: This button allows users to initiate the loading of the web page specified in the address bar.
2. Type of Web Service: In this section of the window, users can switch between different tabs to explore the contents of the chosen web service.
   • WSDL: If the web service adheres to the WSDL standard, users can access and explore its functionalities through this tab.
     

     **WSDL = Web Services Description Language

   • Available Web Services: If the web service is accessible on the server, users can discover and access it from the list provided in this tab.
3. Reference Name: This is a text field that allows users to input a name for the web service reference, facilitating easy identification within the application.
4. Namespace: This is a text field that allows users to define a namespace for the web service reference, aiding in categorization and organization.

   • Example of Namespace Usage

     For example, consider the incorporation of the line:
     
     using System;
     
     At the outset of a program, this allows the developer to employ the code:
     
     Console.WriteLine("Hello, World!");
     
     Instead of:
     
     System.Console.WriteLine("Hello, World!");
     

     !!Users can employ the designated name within this field to call upon the reference in the code environment.

*Namespaces are useful for logically grouping code and averting potential name conflicts, especially in scenarios where multiple libraries coexist within a codebase.

5. Add: This button allows users to integrate the selected web service reference into their application.
6. Cancel: This button allows users to cancel the process of adding the web service reference.
