Asynchronously connects the session using the specified settings.

Namespace: ININ.IceLib.Connection
Assembly: ININ.IceLib (in ININ.IceLib.dll) Version: 0.0.0.0 (22.3.0.218)

Syntax

C#
public void ConnectAsync(
	SessionSettings sessionSettings,
	HostSettings hostSettings,
	AuthSettings authSettings,
	StationSettings stationSettings,
	AsyncCompletedEventHandler completedCallback,
	Object userState
)
Visual Basic
Public Sub ConnectAsync ( _
	sessionSettings As SessionSettings, _
	hostSettings As HostSettings, _
	authSettings As AuthSettings, _
	stationSettings As StationSettings, _
	completedCallback As AsyncCompletedEventHandler, _
	userState As Object _
)

Parameters

sessionSettings
Type: ININ.IceLib.Connection..::..SessionSettings
The SessionSettings for the connection.
hostSettings
Type: ININ.IceLib.Connection..::..HostSettings
The HostSettings for the connection.
authSettings
Type: ININ.IceLib.Connection..::..AuthSettings
The AuthSettings for the connection.
stationSettings
Type: ININ.IceLib.Connection..::..StationSettings
The StationSettings for the connection.
completedCallback
Type: System.ComponentModel..::..AsyncCompletedEventHandler
The callback to invoke when the asynchronous operation completes.
userState
Type: System..::..Object
An optional object that contains state information for this request. This object is a way for the caller to store context information which will be provided to the AsyncCompleted event. If no context information is desired then nullNothingnullptra null reference (Nothing in Visual Basic) may be supplied.

Remarks

For security reasons a user can only be logged in to one station at a time. If the user logs in to a different station, the system drops the original station connection. Multiple instances of client applications may be run on the same machine using different user logins and the same station.

If a user who is logged in via Interaction Client .NET Edition tries, for example, to connect using Interaction Connect, they will receive a message at the original station such as: "Your connection has been dropped due to a subsequent login on a different station".

When completed, the completedCallback delegate is invoked on a thread appropriate to the application-model, such as the GUI thread in a UI application. The Error property of the AsyncCompletedEventArgs-derived object passed to the delegate will contain any exceptions thrown while executing the asynchronous task. See the synchronous version of this method for more detailed error information. For more information on async method calls, see How Async Calls Work.
