android - Check network connection in fragment -


i tried check network connection in sherlockfragment getsystemservice() method not recognized.

below code (from http://developer.android.com/training/basics/network-ops/connecting.html)

    connectivitymanager connmgr = (connectivitymanager) getsystemservice(context.connectivity_service);     networkinfo networkinfo = connmgr.getactivenetworkinfo();     if (networkinfo != null && networkinfo.isconnected()) {         // fetch data     } else {         // display error     }

thanks in advance

the method getsystemservice() not defined on fragments, activity first using getactivity(), e.g.:

connectivitymanager connmgr = (connectivitymanager) getactivity()                              .getsystemservice(context.connectivity_service);  networkinfo networkinfo = connmgr.getactivenetworkinfo();  if (networkinfo != null && networkinfo.isconnected()) {     // fetch data } else {     // display error }

p.s: additianal note: if there potential risk fragment running without being attached activity, check whether getactivity() returns null first.

cheers!

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...
