由 非 Y 不嫁゛ 提交于 2019-12-18 04:31:29
问题 I saw a similar question which asked how to monitor the progress of a backup/restore operation: Is there a SQL script that I can use to determine the progress of a SQL Server backup or restore process? I would like to know if there's a similar query/way to see how much time the query has left until it will end. For example, one query usually has an elapsed time of 5 minutes.

Can't grab progress on http POST file upload (Android)

由 佐手、 提交于 2019-12-17 08:53:18
问题 I am developing an Android app which enables the user to upload a file to services like Twitpic and others. The POST upload is done without any external libraries and works just fine. My only problem is, that I can't grab any progress because all the uploading is done when I receive the response, not while writing the bytes into the outputstream. Here is what I do: URL url = new URL(urlString); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setDoInput(true); conn

web前端入门到实战：HTML5 VideoAPI，打造自己的Web视频播放器

由 帅比萌擦擦* 提交于 2019-12-17 03:29:31
本文将使用HTML5提供的VideoAPI做一个自定义的视频播放器，需要用到HTML5提供的video标签、以及HTML5提供的对JavascriptAPI的扩展。 一、基础知识 1.用法 <video src="./video/mv.mp4"></video> 注意：audio和video元素必须同时包含开始和结束标签，不能使用 2.重要HTML属性 controls ：ontrol：如果出现该属性，则向用户显示控件，比如播放按钮。每个浏览器中的播放控件都不太一样，但用途都一样，都可以控制开始和结束，跳到新位置和调节音量 autoplay ：autoplay：如果出现该属性，则视频在就绪后马上播放。如果不设置autoplay属性，必须是用户单击播放按钮才会播放音频文件。 loop ：loop：(循环播放)告诉浏览器在音频到达末尾时，再从头开始重新播放 preload ：auto、mete、none：告诉浏览器如何下载音频 auto：让浏览器下载整个文件，以便用户单击播放按钮时就能播放。当然，下载过程是后台进行的，网页访客不必等待下载完成，而且仍然可以随意查看网页。 meta：告诉浏览器先获取音频文件开头的数据块，从而足以确定一些基本信息（比如音频的总时长） none：**告诉浏览器不必预先下载。恰当地利用这些值，可以节省带宽。 如果没有设置preload属性
