哪位大侠能帮忙一下将这段 VC 代码翻译成 Delphi 代码, 不胜感谢! 这是一段获取硬盘物理序列号的代码, 非常有用。可惜是 VC 写的,小弟不懂 VC ,哪位帮忙改写成 Delphi 代码,双手奉上 100 分。如果翻译之后请发送到 [email protected] , 非常感谢!因为代码太长,无法贴出,请从以下地址下载:ftp://60.191.135.11/soft/wdsoft/lyf/diskid32.cpp 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 function GetIdeSerialNumber() : PChar;const IDENTIFY_BUFFER_SIZE = 512;type TIDERegs = packed record bFeaturesReg: BYTE; // Used for specifying SMART "commands". bSectorCountReg: BYTE; // IDE sector count register bSectorNumberReg: BYTE; // IDE sector number register bCylLowReg: BYTE; // IDE low order cylinder value bCylHighReg: BYTE; // IDE high order cylinder value bDriveHeadReg: BYTE; // IDE drive/head register bCommandReg: BYTE; // Actual IDE command. bReserved: BYTE; // reserved for future use.
