Open Method (SugarConnection)

In This Topic

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

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Sub Open()

public override void Open()

Remarks

The SugarConnection 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 SugarConnection goes out of scope, the connection it represents does not close automatically. Therefore, you must explicitly close the connection by calling Close.

Opening an open connection does nothing.

Example

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

csharp

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

Visual Basic

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