使用IMAPI 2.0 C ++擦除数据后无法在CD / DVD上写入。

本文介绍了使用IMAPI 2.0 C ++擦除数据后无法在CD / DVD上写入。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

Req Is：我需要检查CD / DVD RW是否有数据，如果是，需要删除数据并在删除后写入新数据。 我可以删除数据但不能能够在那之后写。 请提供C ++中的示例代码，用于删除和使用IMAPI 2.0刻录CD / DVD。 我尝试了什么： 我创建了一个方法EraseMedia（） - 使用intialize，Discmaster初始化，记录器初始化，获取访问权限，DiscFormatErase初始化记录器，擦除数据，释放记录器。 创建一个WriteMedia（） - 使用intialize，Discmaster初始化，记录器初始化，获取访问权限，datastream初始化和写入。 问题： - 当我执行separtely时只有writemethod，它完美地写在DVD /上CD。 - 当我单独执行擦除方法时，完全擦除所有数据。 - 当我调用main方法时 - 第一个时代方法&然后写方法。 它完全执行擦除但在写入之前只抛出错误。不写在CD / DVD上

Req Is : I need to check if CD/DVD RW is having data, if yes need to delete data and write on it new data after deletion. I am able to delete data but not able to write after that. Please provide a sample code in C++ for deletion and burning CD/DVD using IMAPI 2.0. What I have tried: I created a method EraseMedia() -- with intialize, Discmaster initialize, recorder initialize , accquire access, DiscFormatErase intialize with recorder, erase data, release recorder. Created a WriteMedia() -- with intialize, Discmaster initialize, recorder initialize , accquire access , datastream initialize and write. Issues : -- When i am executing separtely only the writemethod , it writes perfectly on the DVD/CD. -- When i am executing separately only erase method, erases all data perfectly. -- When i call in main method -- first erase method & then write method. It executes erase perfectly but before writing only throws error. Doesnt write on CD/DVD

推荐答案

嗯...... CD和DVD不是可重写的设备：一旦你写入物理媒体就可以了，它可以'随后改变，即使有一个燃烧器（这不是真的，IIRC你可以改0到1但不是1到0 - 反之亦然，我不记得随便） 你可以，如果它们是CDRW或DVDRW但你不能用标准的CD和DVD来做。 Um...CD and DVD are not re-writable devices: once you write to the physical media that's it, it can't be changed subsequently, even with a burner (That's not quite true, IIRC you can change 0s to 1s but not 1s to 0s - or vice versa, I can't remember offhand) You can if they are CDRW or DVDRW but you can't do it with standard CD's and DVD's.
