После этих добавлений (DPaint.vb, mModule.vb, MotionPic.vb, open.ico, save.ico) в панели Solution Explorer должны быть файлы, показанные выше. Дважды щёлкая по имени файла, любой файл можно открыть, изучить и редактировать.

Теперь в наш проект добавляем переменные и методы, связанные с формой Form2 для вывода результатов игры.

Открываем файл Form2.vb (например, так: File, Open, File) и вверху записываем директивы для подключения требуемых пространств имен:

Imports System.Drawing.Drawing2D

Imports System.Drawing.Text

Imports System.IO

Теперь в классе Form2 нашего проекта записываем следующие переменные и методы.
