System.Workflow.ComponentModel.ActivityBind activitybind1 = new System.Workflow.ComponentModel.ActivityBind();
this.throwActivity1 = new System.Workflow.ComponentModel.ThrowActivity();
activitybind1.Name = "ThrowWorkflow";
activitybind1.Path = "ThrownException";
//
// throwActivity1
//
this.throwActivity1.Name = "throwActivity1";
this.throwActivity1.SetBinding(System.Workflow.ComponentModel.ThrowActivity.FaultProperty, ((System.Workflow.ComponentModel.ActivityBind)(activitybind1)));
//
// ThrowWorkflow
//
this.Activities.Add(this.throwActivity1);
this.Name = "ThrowWorkflow";
this.CanModifyActivities = false;

Me.CanModifyActivities = True
Dim activitybind1 As New System.Workflow.ComponentModel.ActivityBind()
Me.throwActivity1 = New System.Workflow.ComponentModel.ThrowActivity()
activitybind1.Name = "ThrowWorkflow"
activitybind1.Path = "ThrownException"
' 
' throwActivity1
' 
Me.throwActivity1.Name = "throwActivity1"
Me.throwActivity1.SetBinding(System.Workflow.ComponentModel.ThrowActivity.FaultProperty, activitybind1)
