Opens a QuickBooks Online connection with the property settings specified by the ConnectionString.

Syntax

public override void Open()

'Declaration
 
Public Overrides Sub Open()

Remarks

The QuickBooksConnection 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 QuickBooksConnection 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 QuickBooksConnection, opens it, displays some of its properties, and then closes the connection.

csharp

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

Visual Basic

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