Umbraco how to customize bubble message in EventHandler

Question

my Umbraco version is 4.0.3.

public class MemberEventHandler : ApplicationEventHandler
{
        public MemberEventHandler()
        {
            Member.BeforeSave += new Member.SaveEventHandler(Member_BeforeSave);
        }

        void Member_BeforeSave(umbraco.cms.businesslogic.member.Member sender, umbraco.cms.businesslogic.SaveEventArgs e)
        {         
            e.Cancel = true;
            var clientTool = new ClientTools((Page)HttpContext.Current.CurrentHandler);
            clientTool.ShowSpeechBubble(SpeechBubbleIcon.Success, "Error", "GroupName doesn't exist.");                            
        }

}

Now, I can cancel the save action by setting e.Cancel to true, but the Umbraco's bubble still show "Member Saved" on the page. I try the clientTools, but it can't work.

Could I customize the message in the bubble? Or show the Umbraco's error bubble?

I have searched the problem in forum and stackoverflow, but no answer.

I have a feeling that in later v4 versions, it shows a message if the event was cancelled, but you can't customise it. In that particular version though (which is super old), I think you still get the message, even if you cancel it.
