In the distributed computing model, the client application contains three main components.
 |
Objects for the user interface: These objects include windows, user objects, menus, DataWindows. You write script for the navigation logic. |
|
Proxy objects: One proxy object for each user object that is stored in the server. These proxy objects routs the function calls to the actual object that are stored in the server. You can’t edit a proxy object directly. As long as the proxy object is stored in the same PowerBuilder library, PowerBuilder updates the proxy object whenver you change the remote object (the user object that has the proxy object). |
|
Connection Object: Similar to the transaction object, you need to set the attributes and connect to the server application using ConnectToServer() function. |
