А что полностью проекта нету ? Как-то геморно мне кажется будет все формы, кнопочки,менюшки, имеджи итд по коду восстанавливать, а уж их расположение выходит вообще великая тайна, боюсь задача из разряда нереальных.

Очень жаль, значит придется самому понимать как выглядит электрическое поле. Но все равно спасибо за попытку помочь.

Понимать, как выглядит электрическое поле, гораздо лучше по учебнику физики, чем по программе на Паскале.
