You add a step (an action or a group) to an operating system deployment task sequence group, in System Center 2012 R2 Configuration Manager, by adding the step to the SMS_TaskSequenceGroup.Steps array property.

To add a step to a task sequence group

  1. Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.

  2. Get the SMS_TaskSequenceGroup object that you want to add the step to. For more information, see How to Create an Operating System Deployment Task Sequence Group.

  3. Create the task sequence step. For an example of creating an action step, see How to Add an Operating System Deployment Task Sequence ActionHow to Add an Operating System Deployment Task Sequence Action.

  4. Add the step to the SMS_TaskSequenceGroup.Steps array property.

  5. Reorder the step within the array property as necessary. For more information, see How to Reorder an Operating System Deployment Task Sequence

Example

The following example method adds a command-line action to a task sequence group.

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

Visual Basic Script  Copy Code
Sub AddStepToGroup(taskSequenceStep, group)   

	Dim steps 

	' If needed, create a new steps array.
	If IsNull(group.Steps) Then
		steps = Array(taskSequenceStep)
		group.Steps=steps
	Else
		' Resize the existing steps and add step.
		steps= Array(group.Steps)
		ReDim steps (UBound (group.Steps)+1) 
		group.Steps(UBound(steps))=taskSequenceStep 
	End if 
	 
End Sub
C#  Copy Code
public void AddStepToGroup(
	WqlConnectionManager connection, 
	IResultObject taskSequence, 
	string groupName)
{
	try
	{
		// Get the group.
		List<IResultObject> steps = taskSequence.GetArrayItems("Steps"); // Array of SMS_TaskSequence_Steps.

		foreach (IResultObject ro in steps)
		{
			if (ro["Name"].StringValue == groupName && ro["__CLASS"].StringValue == "SMS_TaskSequence_Group")
			{
				IResultObject action = connection.CreateEmbeddedObjectInstance("SMS_TaskSequence_RunCommandLineAction");
				action["CommandLine"].StringValue = @"C:\donowtingroup.bat";
				action["Name"].StringValue = "Action in group " + groupName;
				action["Description"].StringValue = "Action in a group";
				action["Enabled"].BooleanValue = true;
				action["ContinueOnError"].BooleanValue = false;

				// Add the step to the task sequence.
				List<IResultObject> array = ro.GetArrayItems("Steps");

				array.Add(action);

				ro.SetArrayItems("Steps", array);
				taskSequence.SetArrayItems("Steps", steps);
				break;
		}
	}
}
	catch (SmsException e)
	{
		Console.WriteLine("Failed to create Task Sequence: " + 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.

taskSequence

taskSequenceStep

  • Managed: IResultObject

  • VBScript: SWbemObject

  • A valid task sequence (SMS_TaskSequence).that contains the group.

groupName

group

  • Managed: String

  • VBScript: String

The name of the group that the command-line action is added to. This is obtained from the SMS_TaskSequenceGroup.Name property.
