Reflection

This code is used to change all off  one kind of controls one property to any value in a form.Hard to understand ? Ok let me give you an ex: you want to disable all text box in a form property is enabled value is false very easy.

private static ArrayList controls = new ArrayList();

    public static Control[] LookControls(Form f,Type ctrlType,string property,object value)

    {

        foreach (Control c in f.Controls)

        {

            LookControls(c, ctrlType,property,value);

        }

        return (Control[])controls.ToArray(typeof(Control));

    }

    private static void LookControls(Control ctrl, Type ctrlType,string property,object value)

    {

        if (ctrl.GetType() == ctrlType)

        {

            controls.Add(ctrl);

            PropertyInfo p = ctrl.GetType().GetProperty(property);

            p.SetValue(ctrl, value, null);

        }

        if (ctrl.Controls != null)

        {

            foreach (Control ctrl1 in ctrl.Controls)

            {

                LookControls(ctrl1,ctrlType,property,value);

            }

        }

    }
