Using the Connection Object – PB Docs 120


Using the Connection Object

Build a .NET client application for an EAServer component using the Connection
object.

  1. Use the Template Application target wizard to create
    a client application, then use a .NET application wizard to create
    a .NET target using the library list and application object of the
    target you just created.

    Alternatively, use a .NET target wizard to build a client
    application from scratch.


  2. Use the EAServer Connection
    Object Wizard to create a standard class user object inherited from
    the Connection object. You can then use this object in a script
    to establish a connection. First set connection options, then call
    the ConnectToServer function.

    If you use the Template Application wizard to create the client
    application, you can create the Connection object in that wizard.

  3. Use the EAServer Proxy
    Wizard to create a project for building a proxy object for each
    EAServer component that the .NET client will use, then generate
    the proxy objects. The EAServer Proxy icons on the Project page of
    the New dialog box are enabled for all .NET target types.

  4. Write the code required to create the EAServer component instance using the CreateInstance function.
  5. Call one or more component methods from the client.

The steps are the same for .NET clients and standard PowerBuilder
clients. For detailed steps, see Application Techniques > Building
an EAServer Client
.
