{

The SHFormatDrive API provides access to the Shell's format

dialog box. This allows applications that want to format disks to bring

up the same dialog box that the Shell uses for disk formatting.

}

const

SHFMT_DRV_A = 0;

SHFMT_DRV_B = 1;

SHFMT_ID_DEFAULT = $FFFF;

SHFMT_OPT_QUICKFORMAT = 0;

SHFMT_OPT_FULLFORMAT = 1;

SHFMT_OPT_SYSONLY = 2;

SHFMT_ERROR = -1;

SHFMT_CANCEL = -2;

SHFMT_NOFORMAT = -3;

function SHFormatDrive(hWnd: HWND;

Drive: Word;

fmtID: Word;

Options: Word): Longint

stdcall; external 'Shell32.dll' Name 'SHFormatDrive';

procedure TForm1.Button1Click(Sender: TObject);

var

FmtRes: Longint;

begin

try

FmtRes := ShFormatDrive(Handle,

SHFMT_DRV_A,

SHFMT_ID_DEFAULT,

SHFMT_OPT_QUICKFORMAT);

case FmtRes of

SHFMT_ERROR: ShowMessage('Error formatting the drive');

SHFMT_CANCEL: ShowMessage('User canceled formatting the drive');

SHFMT_NOFORMAT: ShowMessage('No Format')

else

ShowMessage('Disk has been formatted!');

end;

except

ShowMessage('Error Occured!');

end;

end;

{

Normally, if a diskette is not in the drive when SHFormatDrive is called,

the system displays a critical error dialog box that asks the user

to Abort, Retry, or Ignore.

You can prevent the system from displaying this dialog box by calling

the SetErrorMode API with SEM_FAILCRITICALERRORS.

}

var

EMode: Word;

begin

EMode := SetErrorMode(SEM_FAILCRITICALERRORS);

// ShFormatDrive Code....

SetErrorMode(EMode);

end;
