Подстройка программы под разрешение экрана - VB
Формулировка задачи:
Всем здрям. Вас уже, видимо, задолбали с вопросом "Как подстроить прогу под экран?".. Извиняюсь, но перелопатив гугл, я ничего не нашёл. Коды были, но не совсем те, что мне нужно. Нужно сделать вот что:
Ну, первое, узнать разрешение экрана, которое сейчас у пользователя.
А потом подстроить программу на всё окно. Что бы и картинки изменили свой размер, текст.. В общем, как у нормально программы. И вообще, можно ли такое сделать в ВБ?.. Заранее спасибо..
