编程地弹出和收回在vb.net或C＃CD驱动器 [英] Programatically ejecting and retracting the CD drive in vb.net or c#

问题描述

有没有办法这样做呢？我知道它可以以编程方式退出/缩回莫名其妙的CD驱动器，导致Roxio的做，当它提示我插入磁盘。

C＃或vb.net为preferable，但C和C ++都还好过作为最后的手段。

我几乎可以肯定的是有一些方法来做到这一点，我只是不知道这个方法调用。

我明白这是一个有点不寻常的要求，如谷歌，当我搜索的方法，取得了绝对没有...

解决方案

 使用System.Runtime.InteropServices;函数[DllImport（WINMM.DLL）]
静态外部的Int32 mciSendString（字符串命令，StringBuilder的缓冲区，缓冲区大小的Int32，IntPtr的hwndCallback）;//要开门
mciSendString（设置CDAudio开门，NULL，0，IntPtr.Zero）;//关门
mciSendString（设置CDAudio大门紧闭，NULL，0，IntPtr.Zero）;

Is there any way to do so? I know its possible to programmatically eject/retract the cd drive SOMEHOW, cause Roxio does that when it prompts me to insert a disk.

Either c# or vb.net is preferable, but c and c++ are okay too as a last resort.

I am nearly positive there is some way to do this, I just don't know the methods to call.

I do understand this is a somewhat unusual request, as Google yielded absolutely nothing when I searched for the methods...

解决方案

using System.Runtime.InteropServices;

[DllImport("winmm.dll")]
static extern Int32 mciSendString(String command, StringBuilder buffer, Int32 bufferSize, IntPtr hwndCallback);

// To open the door
mciSendString("set CDAudio door open", null, 0, IntPtr.Zero);

// To close the door
mciSendString("set CDAudio door closed", null, 0, IntPtr.Zero);
