c# - WPF full screen on maximize -

-

i want have wpf window go in full screen mode, when f11 pressed or maximize button in right top corner of window pressed.

while following works charm pressing f11:

private void window_keydown(object sender, keyeventargs e) {     if (e.key == key.f11)     {         windowstyle = windowstyle.none;         windowstate = windowstate.maximized;         resizemode = resizemode.noresize;     } }

this still displays windows taskbar (tested windows 7):

protected override void onstatechanged(eventargs e) {     if (windowstate == windowstate.maximized)     {         windowstyle = windowstyle.none;         windowstate = windowstate.maximized;         resizemode = resizemode.noresize;     }     base.onstatechanged(e); }

what missing here? or can more elegant?

wpf seems making decision whether go full-screen or respect taskbar based on windowstyle @ time of maximisation. kludgy effective solution switch window non-maximised, set windowstyle, , set window maximised again:

private bool _instatechange;  protected override void onstatechanged(eventargs e) {   if (windowstate == windowstate.maximized && !_instatechange)   {     _instatechange = true;     windowstate = windowstate.normal;     windowstyle = windowstyle.none;     windowstate = windowstate.maximized;     resizemode = resizemode.noresize;     _instatechange = false;   }   base.onstatechanged(e); }

although code ugly, transition normal , maximized doesn't seem make user experience worse. on display, noticed flicker both f11 code , kludge maximise, not noticeably worse on kludge maximise. mileage may vary!

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
