1. You are writing a sequential console workflow that consists of a delay activity and a code activity, as
shown in the exhibit. (Click the Exhibit button for the sequential console workflow image.)
In the execution code of the second activity, you try to modify the workflow as follows:
Private Sub delayActivity_InitializeTimeoutDuration(ByVal sender As System.Object, ByVal e As
System.EventArgs)
Console.Title = “Modifiability of a Workflow”
Console.WriteLine(”Wait …”)
End Sub
Private Sub codeActivity_ExecuteCode(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim delay As DelayActivity = CType(sender, DelayActivity)
Console.WriteLine(delay.Name)
Dim workflowChanges As New WorkflowChanges(Me)
Dim codeActivity As New CodeActivity()
codeActivity.Name = “codeActivity2″
AddHandler codeActivity.ExecuteCode, AddressOf Me.codeActivity2_ExecuteCode
workflowChanges.TransientWorkflow.Activities.Add(codeActivity)
Me.ApplyWorkflowChanges(workflowChanges)
End Sub
Private Sub codeActivity2_ExecuteCode(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim codeActivity As CodeActivity = CType(sender, CodeActivity)
Console.WriteLine(codeActivity.Name)
Console.ReadLine()
End Sub
You also have set the modifiability of the workflow to a code condition that is set to the following function:
Private Sub UpdateCondition(ByVal sender As System.Object, ByVal e As ConditionalEventArgs)
If (TimeSpan.Compare(Me.delayActivity.TimeoutDuration, New TimeSpan(0, 0, 5)) > 0) Then
e.Result = False
Else
e.Result = True
End If
End Sub
Which code segment should you use to handle the exception?
A. workflowChanges.TransientWorkflow.Activities.Add(codeActivity)

Catch ex As OverflowException
Console.WriteLine(ex.GetType().ToString())
Console.ReadLine()
End Try
