Open Method (ExactTargetConnection)

In This Topic

Opens a ExactTarget connection with the property settings specified by the ConnectionString.

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides NotOverridable Sub Open()

public override void Open()

Remarks

The ExactTargetConnection draws an open connection from the connection pool if one is available. Otherwise, it establishes a new connection to the data source.

Note: If the ExactTargetConnection goes out of scope, the connection it represents does not close automatically. Therefore, you must explicitly close the connection by calling Devart.Common.DbConnectionBase.Close.

Opening an open connection does nothing.

Example

The following example creates a ExactTargetConnection, opens it, displays some of its properties, and then closes the connection.

csharp

public void CreateExactTargetConnection(string myConnString)
{
  ExactTargetConnection exactTargetConnection = new ExactTargetConnection(myConnString);
  exactTargetConnection.Open();
  MessageBox.Show("ServerVersion: " + exactTargetConnection.ServerVersion
    + "\nState: " + exactTargetConnection.State.ToString());
  exactTargetConnection.Close();
}

Visual Basic

Public Sub CreateExactTargetConnection(myConnString As String)
  Dim exactTargetConnection As New ExactTargetConnection(myConnString)
  exactTargetConnection.Open()
  MessageBox.Show("ServerVersion: " + exactTargetConnection.ServerVersion _
    + ControlChars.Cr + "State: " + exactTargetConnection.State.ToString())
  exactTargetConnection.Close()
End Sub
