/// hook delegate
/// </summary>
/// <param name="sender"></param>
/// <param name="target"></param>
/// <param name="eventname"></param>
/// <param name="functionname"></param>
public static void hookDelegate(object sender, EventHandler handler, String eventname, String multi1, String multi2)
{
if (sender == null)
{
throw new ArgumentNullException("sender");
}
if (handler == null)
{

}
try
{
EventInfo evClick = sender.GetType().GetEvent(eventname);
//check if a delegate is already hooked
if (multi1.Equals("Single",StringComparison.OrdinalIgnoreCase))
{
FieldInfo fi = sender.GetType().GetField(eventname, BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Public | BindingFlags.FlattenHierarchy);
if (fi != null)

}
MethodInfo addHandler = evClick.GetAddMethod();
Object[] addHandlerArgs = { handler };
addHandler.Invoke(sender, addHandlerArgs);
}
catch (Exception ex)
{
//log.Error(ex);
//throw ex; //TODO make some logging and dont throw
throw new Exception("Error in hookDelegate: " + eventname + " - " + " - " + sender.ToString() + " - " + handler.ToString() + " - " + ex.Message);
