here's source comment method: note on android, application lifecycle not include vm termination, calling method not ensure files deleted. instead, should use appropriate out of: * use {@code finally} clause manually invoke {@link #delete}. * maintain own set of files delete, , process @ appropriate point in application's lifecycle. * use unix trick of deleting file readers , writers have opened it. no new readers/writers able access file, existing ones still have access until last 1 closes file. can explain me "unix trick" mentioned in , how use it? this answer has explanation: https://stackoverflow.com/a/5219960/200508 . basically, means "deleting" file on unix system doesn't erase disk; instead, deletes reference file directory it's in. file isn't erased until processes using terminate. thus, can open temporary file , delete it, , whenever program terminates automatically erased.

i want study kernel of linux without distribution. i found loadlin boatloader of ms-dos, think works in older version of windows (windows 95,98, me). so need install kernel in pc if possible. how can install it? the kernel not useful you; you'll need shell , working compiler if want test things first-hand, , these not part of kernel. there's distribution called linux scratch allows install kernel , whatever other stuff want, literally scratch (as in, compiling stuff , adding want) i wondering though, want study , how having distribution affect studying of kernel? (yes, distributions ship custom kernels major features same)

has seen specific kind of distortion xaml text rendering? this happens when page first renders when browser re-sized bigger or smaller render correctly. i have tried different text-rendering settings , made sure not setting height or width constraints impacting text. this happens text of custom buttons created. have effects-rendering? buttons , groupboxes have dropshadows, affect plain text on white background? thanks! jeff does have effects-rendering? buttons , groupboxes have dropshadows, affect plain text on white background? yes. setting effect , bitmapeffect , or cachemode on element causes element rasterized, i.e., converted scalable vector form bitmapped form. can create visual artifacts jagged edges (aliasing) when element gets positioned across device pixels or scaled in size, , text elements tend suffer most. i avoid using such effects when possible. may able mitigate problems setting uselayoutrounding (wpf 4+) or snapstodevicepixels (...

i use python 3 , pyqt5. here's test pyqt5 program, focus on last 2 lines: from pyqt5.qtcore import * pyqt5.qtwidgets import * import sys class window(qwidget): def __init__(self,parent=none): super().__init__(parent) self.setwindowtitle('test') self.resize(250,200) app=qapplication(sys.argv) w=window() w.show() sys.exit(app.exec()) #sys.exit(app.exec_()) i know exec language keyword in python. code on official pyqt5 documentation (specifically object destruction on exit part) . see example shows use of app.exec() confuses me. when tested on machine. found there no visible difference end. both , without _ produces same output in no time difference. my question is: is there wrong going when use app.exec() ? clashing python's internal exec ? suspect because both exec 's executing something. if not, can use both interchangeably? that's because until python 3, exec was reserved keyword , pyqt devs added underscore it. pyt...

i want application run in same way gmail does. once visit mail color changes permanently when reload page remains same 'here fiddle' http://jsfiddle.net/kzsjr/#&togetherjs=opoxyfna4o when click on 'po' button row color must change permanently in gmail thank help you have use localstorage , this: $("#po").click(function(){ localstorage.setitem("visited", true); $("#po").css("color", "black"); // visited }); now on page load, $(window).load(function(){ if(localstorage.getitem("visited")) { $("#po").css("color", "black"); // visited } else { $("#po").css("color", "green"); // not visited } }); alternatively, can use cookies (but usage becomes bit lengthy imo). p.s. note localstorage can modified users, , not used storing sensitive user data. further reading .

datatable dt = new datatable(); var dr = dt1.date; string rr = convert.tostring(dr); datacolumn dc1=new datacolumn(); dc1.columnname = rr; dt.columns.add(dc1); and if add datarow after like dt.rows.add("hello","hello1","hello2"); datagrid1.itemssource = dt.defaultview; the data not displayed in grid . if comment line dc1.columnname = rr; the values displayed want colmn name date "dt1" here pleae note dt1 date values dynamic , incremented in each loop. dt1 = dt1.adddays(1); please help without seeing xaml data grid it's difficult sure imagine you've specified field name date column in xaml. to resolve this, you'll need set autogeneratecolumns=true , let grid automatically find field name.
