Release 10.1A: OpenEdge Development:
.NET Open Clients

Connecting to the AppServer

To establish a connection to an AppServer using the .NET OpenAPI, you must instantiate a Progress.Open4GL.Proxy.OpenAppObject. You can create an OpenAppObject using one of the following constructors:

Syntax

public OpenAppObject (Connection connectObj, string appservice) public OpenAppObject (string url, string userid, string password, string appserver-info, string appservice) public OpenAppObject (string userid, string password, string appserver-info, string appservice) public OpenAppObject (string appservice)

connectObj

Specifies a Progress.Open4GL.Proxy.Connection object, which defines connection parameters to access the AppServer. For more information on this object, Chapter 3, " Connecting to an AppServer."

appservice

Specifies the name of the application service.

url

Specifies the URL to connect to an Appserver URL. Defaults to AppServer://localhost:5162/appService. For more information on forming this URL, see the sections on connecting to the AppServer using a URL in OpenEdge Application Server: Developing AppServer Applications .

Note: For an HTTPS connection using the AppServer Internet Adapter (AIA) with the Web server running on the .NET Open Client machine, you must specify the Internet host name (not "localhost") in the URL exactly as it appears in the CN field of the Web server certificate.

userid

Specifies a user ID required to access the AppServer.

password

Specifies a password required to access the AppServer.

appserver-info

Specifies information required by the application service at connection time.

You can set a number of session and run-time properties to manage access to an application service. For example, to access a session-free AppServer using the .NET OpenAPI, you must set the proxy property PROGRESS.Session.SessionModel to 1. For more information on setting this and other session properties see Chapter 5, " Accessing Proxy Properties.".
