To get feedback, I will be embedded on the home page when designing the home page. Reader to connect with us. The most common practice is to use HTML language plus: feedback to author! This is the disadvantage of this is whether the reader is using Internet Explorer or Netscape Navigator, you need to open a writing window in the case of clicking the author address, so that the home window is overwritten . This reader does not easily take it in this reader. The author sets a Java applet on the home page to solve this problem, which makes people who do not have the Email address can also feed.

COM "); // Fill in the reader's mail server iphostpanel.add (Hostfield); add (" north ", fields); msgarea = new textarea (); add (" center ", msgarea) Add ("South", New Button ("Send"));} public boolean handleevent (EVENT E) {if (E.ID == Event.Window_Destroy) System.exit (0); Return Super.HandleEvent (E) } public boolean action {if (arg.equals ("send")) Sendmsg (Senderfield.getText (), Recipientfield.getText (), hostfield.getText (); Elsereturn Super.Action e, arg); Return True;} private video
