PHP windows create hidden files

由 你说的曾经没有我的故事 提交于 2019-12-19 03:41:31
问题 Is it possible to create hidden files/folders on windows using php (xampp)? And if it is, how? 回答1: A file in Windows is hidden if it has the hidden attribute set on it. There is no built in function to do this, so you need to use system/exec to execute the attrib application. Like this: $file = 'test.txt'; system('attrib +H ' . escapeshellarg($file)); This will set the hidden (+H) flag on test.txt. 回答2: You could call attrib: $filename = 'c:\\some\\file.txt'; exec('attrib +h '.$filename);

jQuery: How to get content not visible with overflow: hidden?

由 僤鯓⒐⒋嵵緔 提交于 2019-12-18 13:59:09
问题 I'm trying to span content across multiple pages (divs) set at a height of 950px per div, so I can properly output to pdf. I start off with one div which nests all of the content using overflow: hidden. Ideally I'd like to use jquery to find content which is out of the viewing scope (hidden), but I can't see any functionality to do this. $...(':visible') just applies to display: none or visibility: hidden... The content on these pages is basic html markup (p, br, ol, ul, li, h1, h2). I've

Magento read-only and hidden product attributes

由 女生的网名这么多〃 提交于 2019-12-18 03:56:25
问题 I would like to have some Magento product attributes that are not editable from the admin interface and some that are not visible at all in that interface (as a method of storing some persistent information about a product that should not be viewed by human users.. it's the only way of doing this that i can think of, any other suggestions are welcome). So my question is: Do all Magento attributes have to be visible and editable from the admin interface? If not, how can they be made read-only

How to hide elements with jQuery before they get rendered?

由 别等时光非礼了梦想. 提交于 2019-12-17 22:13:13
问题 I want to generate html layout with areas (divs, spans) that can be shown/hidden conditionally. These areas are hidden by default. If I call .hide() method with jquery on document.ready these areas may blink (browsers render partially loaded documents). So I apply "display: none" style in html layout. I wonder what is the best practice to avoid blinking, because applying "display:none" breaks incapsulation rule - I know what jquery does with hide/show and use it. If jquery's hiding/showing

What's the best way to identify hidden characters in the result of a query in SQL Server (Query Analyzer)?

由 守給你的承諾、 提交于 2019-12-17 17:56:19
问题 When trying to identify erroneous data (often needing manual review and removal), I'd like an easy way of seeing hidden characters, such as TAB, Space, Carriage return and Line feed. Is there a built-in way for this? In a similar question here on stackoverflow, regarding Oracle, a DUMP(fieldname) function was suggested, but I don't know if that woud make things easier even if a corresponding function would exist in SQL Server, since I need to see the Characters in their context. The best idea

Google maps in hidden div

由 对着背影说爱祢 提交于 2019-12-17 16:30:41
问题 I have a page with two tabs. The first tab has photos and the second a google map. The problem is that the google map is not completely drawing because it is in a hidden div. So I moved the initialize() function to the href of the map tab using onclick(). This works the first time you click on it but when you return to the photos tab and then go back to the map tab the map only partially draws. If you click the map tab a second time it works perfectly. Any ideas? tabs javascript: <script type

Get the offset of a hidden element

由 杀马特。学长 韩版系。学妹 提交于 2019-12-17 15:39:22
问题 How can I get the coordinates of a hidden element? offset() doesn't support the use for hidden elements. Any hints? 回答1: If your element has had .hide() called on it, or if it's got display:none in css, the browser doesn't bother rendering it at all. In this case, the answer is not directly. In recent jQueries, you can't even get its width or height. On the other hand, if you .show() an element, then .hide() it before an execution loop (an event firing through to when there's no more code to

c++ overloaded virtual function warning by clang?

由 半腔热情 提交于 2019-12-17 15:35:26
问题 clang emits a warning when compiling the following code: struct Base { virtual void * get(char* e); // virtual void * get(char* e, int index); }; struct Derived: public Base { virtual void * get(char* e, int index); }; The warning is: warning: 'Derived::get' hides overloaded virtual function [-Woverloaded-virtual] (the said warning needs to be enabled of course). I don't understand why. Note that uncommenting the same declaration in Base shuts the warning up. My understanding is that since

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 可用的类 当视口宽度等于或宽于给定的分隔点时， .hidden-*-up 类将隐藏该元素。比如说， .hidden-md-up 将在中屏、大屏、特大屏视口中隐藏元素。 当视口宽度等于或窄于给定的分隔点时， .hidden-*-down 将隐藏该元素，比如说， .hidden-md-down 将在特小屏、小屏、中屏视口中隐藏元素。 你可以组合使用 .hidden-*-up 类以及 .hidden-*-down 类，以使元素只在一个给定的屏幕尺寸区间内显示。比如说， .hidden-sm-down.hidden-xl-up 能使元素只在中屏和大屏视口中显示。使用多个 .hidden-*-up 类或多个 .hidden-*-down 类是多余而且无意义的。 当一个元素的可见性不能被表达为一个单独连续的视口尺寸范围时，这些类并不会支持这些比较少见的情况。在这种情况下，你必须改用自定义类。 特小屏设备 手机竖屏(<34em) 小屏设备 手机横屏 (≥34em) 中屏设备 平板电脑 (≥48em) 大屏设备 桌面 (≥62em) 特大屏设备 桌面 (≥75em) .hidden-xs-down 隐藏 可见 可见 可见 可见 .hidden-sm-down 隐藏 隐藏 可见 可见 可见 .hidden-md-down 隐藏
