Open CD tray exists, but I can't seem to make it close especially under W2k. I am especially looking for a method to do this from a batch file, if possible, but API calls would be OK. 回答1: Here is an easy way using the Win32 API: [DllImport("winmm.dll", EntryPoint = "mciSendStringA", CharSet = CharSet.Ansi)] protected static extern int mciSendString(string lpstrCommand,StringBuilder lpstrReturnString,int uReturnLength,IntPtr hwndCallback); public void

Tips on finding the volume of water in a 3d chess board

笑着哭i 提交于 2019-12-03 08:14:22
So I have an assignment where I have to recreate a 3d chessboard that is a RxC grid of squares each being a different height. If the chessboard is water tight, and someone pours water all over it until it can hold no more water, it will hold a fixed amount of water. If the board is already holding its maximum volume of water, any excess water poured onto the board will drain off the edges, there is no tall container surrounding the board. You can assume the squares on the chess board are one inch square, and the heights are given in inches. int CalcContainedWater( const int *p_data, int num

How to get a volume measurement of iPhone recording in dB, with a limit of at least 120dB

南笙酒味 提交于 2019-12-03 07:54:36
问题 I am trying to make a simple volume meter for the iPhone. I want the volume to be displayed in dB. When using this turorial, I am only getting measurements up to 78 dB. I've read that that is because the dBFS spectrum for 16 bit audio recordings is only 96 dB. I tried modifying this piece of code in the init function: dataFormat.mSampleRate = 44100.0f; dataFormat.mFormatID = kAudioFormatLinearPCM; dataFormat.mFramesPerPacket = 1; dataFormat.mChannelsPerFrame = 1; dataFormat.mBytesPerFrame = 2

How to specify an iterator in the volume path when using docker-compose to scale up service?

牧云@^-^@ 提交于 2019-12-03 06:17:47
Background: I'm using docker-compose in order to place a tomcat service into a docker swarm cluster but I'm presently struggling with how I would approach the logging directory given that I want to scale the service up yet retain the uniqueness of the logging directory. Consider the (obviously) made up docker-compose which simply starts tomcat and mounts a logging filesystem in which to capture the logs. version: '2' services: tomcat: image: "tomcat:latest" hostname: tomcat-example command: /start.sh volumes: - "/data/container/tomcat/logs:/opt/tomcat/logs,z" Versions docker 1.11 docker

docker数据持久化

如果想让数据持久保留: 1、Docker 的绑定挂载功能,这个功能可以将宿主系统的文件或文件夹挂载到容器里 2、使用 Docker 卷来创建一个卷并挂载到容器里。 下面我们就一起来了解下这两种方法以及如何使用。 Docker 绑定挂载 Docker 绑定挂载可以让宿主系统的文件夹挂载到容器里,常用于文件共享,也可以用于数据持久化,不过官方更推荐使用 Docker 卷(等会讲)。 绑定挂载需要在创建容器的时候进行挂载,挂载的方式也很简单,只需要添加 -v 参数。 例如: 在宿主系统创建一个/tmp/jason文件夹并创建一个test文档,文档内容为“hello,jason”: mkdir /tmp/jasonecho "hello,jason" >/tmp/jason/test.txt 查看test.txt 创建一个容器将刚刚创建的文件夹挂载到容器里 docker run -itd -v /tmp/jason:/test --name mivm alpine /bin/sh -v 后面的两个参数,第一个是宿主系统路径,第二个是挂载目标路径,可以用来挂载文件夹,也可以用来挂载文件,而且可以挂载多个,只需要添加多个 -v 即可,如果宿主系统里不存在文件夹,Docker 会自动创建文件夹。 默认情况下 mount 的数据是可读可写的。我们可以添加 ro 参数设置成只读权限,此时:

Docker mount to folder overriding content

非 Y 不嫁゛ 提交于 2019-12-03 03:36:30
I have a .net Core web Api having configurations files under a folder called Config. I created the image and a container from it, and I correctly see using the terminal, that the container contains the folder and the configuration files inside. My problem is that so far I couldn't find a way to create the same container mounting/binding the Config folder to a physical path, following the requirements: 1) Mount Config folder to a specific host location 2) On container creation, the Config folder should be filled with the files in the image 3) On container creation, override any existing file
