BOOLEAN? Programm Problem!

[DaddyRe]

So,

Delphi-Quellcode:

function GetVolumeName(DriveLetter: Char): string;
var
  dummy: DWORD;
  buffer: array[0..MAX_PATH] of Char;
  oldmode: LongInt;
begin
  oldmode := SetErrorMode(SEM_FAILCRITICALERRORS);
  try
    GetVolumeInformation(PChar(DriveLetter + ':\'),
                         buffer,
                         SizeOf(buffer),
                         nil,
                         dummy,
                         dummy,
                         nil,
                         0);
    Result := StrPas(buffer);
  finally
    SetErrorMode(oldmode);
  end;
end;

// Example, Beispiel:

procedure TForm1.Button1Click(Sender: TObject);
begin
  Caption := GetVolumeName('c');
end;
