TRPCBroker Component Tutorial Introduction

The major functions of a TRPCBroker component in a Delphi application are to:

• Connect to an RPC Broker server system from a client.
  
  
• Execute remote procedure calls (RPCs) on that system.
  
  
• Return data results from RPC to the client.

This tutorial guides you through using a TRPCBroker component to perform each of these tasks, by having you create a Delphi application, step-by-step. This application will retrieve a list of terminal types from the server, and display information about each terminal type.

After you have completed this tutorial, you should be able to:

• Include a TRPCBroker component in a Delphi application.
  
  
• Retrieve the end-user workstation's designated server and port to connect to.
  
  
• Establish a connection through the RPC Broker component to an RPC Broker server.
  
  
• Create M routines that return data in the formats necessary to be called from RPCs.
  
  
• Create RPCs.
  
  
• Call RPCs from a Delphi application to retrieve data from VISTA database.
  
  
• Pass parameters from your Delphi application to RPCs.
