applescript - How to detect if user is away in OSX? -


i want start script when user goes away or returns computer. there built-in method in applescript check user's state? if not else can use in osx?

here's command might work you. tell how long it's been since mouse moved or keystroke pressed.

set idletime shell script "ioreg -c iohidsystem | awk '/hididletime/ {print $nf/1000000000; exit}'"

so might assume if no key pressed or mouse moved period of time user not using computer. clever tracking of idletime can tell when user left computer , when returned. this.

save applescript application , check "stay open after run handler" checkbox. can quit time right-clicking on dock icon , choosing quit.

global timebeforecomputerisnotinuse, computerisinuse, previousidletime  on run     set timebeforecomputerisnotinuse 300 -- 5 minutes     set computerisinuse true     set previousidletime 0 end run  on idle     set idletime (do shell script "ioreg -c iohidsystem | awk '/hididletime/ {print $nf/1000000000; exit}'") number      if not computerisinuse         if idletime less previousidletime             set computerisinuse true             "user using computer again."         end if     else if idletime greater or equal timebeforecomputerisnotinuse         set computerisinuse false         "user has left computer."     end if      set previousidletime idletime     return 1 end idle

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
