Opens a Salesforce.com or Database.com connection with the property settings specified by the ConnectionString.

Syntax

Visual Basic
C#

public override void Open()

'Declaration
 
Public Overrides Sub Open()

Remarks

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

csharp

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

Visual Basic

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