用得着用format.com吗?在shell32.dll就有这样的函数:
There is an API hidden away in Shell32.dll called SHFormatDrive, this brings up the standard format removable drive dialog. I stumbled across this in the borland.public.delphi.winapi newsgroup.
{implementation section}
..
..
const
SHFMT_ID_DEFAULT = $FFFF;
// Formating options
SHFMT_OPT_QUICKFORMAT = $0000;
SHFMT_OPT_FULL = $0001;
SHFMT_OPT_SYSONLY = $0002;
// Error codes
SHFMT_ERROR = $FFFFFFFF;
SHFMT_CANCEL = $FFFFFFFE;
SHFMT_NOFORMAT = $FFFFFFFD;
function SHFormatDrive(Handle: HWND; Drive, ID, Options: Word): LongInt;
stdcall; external 'shell32.dll' name 'SHFormatDrive'
procedure TForm1.btnFormatDiskClick(Sender: TObject);
var
retCode: LongInt;
begin
retCode:= SHFormatDrive(Handle, 0, SHFMT_ID_DEFAULT,
SHFMT_OPT_QUICKFORMAT);
if retCode < 0 then
ShowMessage('Could not format drive');
end;
end.
