You create an association between a reference and destination computer, in Microsoft System Center Configuration Manager 2007, by calling the AddAssociation Method in Class SMS_StateMigration.

Note

You call the DeleteAssociation Method in Class SMS_StateMigration to delete an association.

To create an association between two computers

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Call the AddAssociation Method in Class SMS_StateMigration.

Example

The following example method adds an association between a source and reference computer.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Sub AssociateComputer(connection, referenceComputerResourceId, destinationComputerResourceId)
    
    Dim stateMigrationClass
    Dim inParams
    Dim outParams
   
    ' Get the state migration class.
    Set stateMigrationClass = connection.Get("SMS_StateMigration")

    ' Set up the parameters.
    Set inParams = _
      stateMigrationClass.Methods_("AddAssociation").InParameters.SpawnInstance_
    inParams.SourceClientResourceID = referenceComputerResourceId
    inParams.RestoreClientResourceID = destinationComputerResourceId
    
    ' Call the method.
    Set outParams = _
      connection.ExecMethod( "SMS_StateMigration", "AddAssociation", inParams)   
 
   End Sub

public void AssociateComputer(
    WqlConnectionManager connection, 
    int referenceComputerResourceId, 
    int destinationComputerResourceId)
{
    try
    {
        // Set up the reference and destination computer in parameters.
        Dictionary<string, object> inParams = new Dictionary<string, object>();
        inParams.Add("SourceClientResourceID", referenceComputerResourceId);
        inParams.Add("RestoreClientResourceID", destinationComputerResourceId);

        // Create the computer association.
       connection.ExecuteMethod("SMS_StateMigration", "AddAssociation", inParams);
    }
    catch (SmsException e)
    {
        Console.WriteLine("failed to make the association" + e.Message);
        throw;
    }
}

The example method has the following parameters:

Parameter	Type	Description
connection	Managed: WqlConnectionManager VBScript: SWbemServices	A valid connection to the SMS Provider.
referenceComputerResourceID	Managed: Integer VBScript: Integer	The Configuration Manager resource identifier for the reference computer. This is available from SMS_R_System class ResourceId property for the computer.
destinationComputerResourceID	Managed: Integer VBScript: Integer	The Configuration Manager resource identifier for the destination computer. This is available from SMS_R_System class ResourceId property for the computer.
