Open Method (DynamicsConnection)

In This Topic

Opens a Dynamics CRM connection with the property settings specified by the ConnectionString.

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Sub Open()

public override void Open()

Remarks

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

csharp

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

Visual Basic

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

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
