wpf - A window with no taskbar icon, no appearance in Alt-Tab and *without* using the ToolWindow extended style -


i have problem appears new windows 10.

i want create form visible user, no task bar icon , not appear in alt+tab.

this doable if 1 happy sacrifice normal styling of window following accepted solutions here either wpf or windows forms.

the general advice both wpf , windows forms is:

  • set showintaskbar false
  • enable toolwindow styling (either through setting border style in winforms or windowstyle in wpf)

however, has new, practical problem in windows 10 when using virtual desktops: moment above, wpf or winforms window appear in every virtual desktop. see example application red background:

window appears in every virtual desktop

this affects both task view switching screen , actual desktop itself. no matter go, form there!

is there way show form - or bitmap - on windows without appearing in taskbar, without appearing in alt+tab and without duplicating window on every virtual desktop?

i have spent 2 days researching every possible option, trying every example online, reading msdn documentation on window styles etc. resort same method, either through p/invoke calls or directly, either way result same.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
