thank help

you can scroll html elemet htmlelement.scrollintoview.

see example:

 public partial class form1 : form     {         public form1()         {             initializecomponent();             webbrowser1.documentcompleted += new webbrowserdocumentcompletedeventhandler(webbrowser1_documentcompleted);         }          private void form1_load(object sender, eventargs e)         {             webbrowser1.documenttext = "<html><body><span class=\"cls\" id=\"el\"> </body></html>";         }          void webbrowser1_documentcompleted(object sender, webbrowserdocumentcompletedeventargs e)         {             //for element id             webbrowser1.document.getelementbyid("el").scrollintoview(true);             //for element spesific             foreach (htmlelement el in webbrowser1.document.all)             {                 if (el.getattribute("classname") == "cls")                 {                     el.scrollintoview(true);                 }              }          }       }

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
