Доброе время суток!
Я начинаю программист, недавно перешел с 'C++' на 'C#', так что строго прошу не судить, а по возможности указать на ошибки.
# Задача:
Необходимо написать программу, которая будет перехватывать нажатия кнопок клавиатуры 'F11', 'F12' (Низкоуровневой) — Это осуществил.
При нажатие на кнопку 'F11', Необходимо менять статус окна из 'FullScreen' в 'WindowMode' и наоборот — Это осуществил.
При нажатие на кнопку 'F12', необходимо скрывать(Hide)/показывть(Show) окно. — Тут проблема.
# Детально о проблеме:
Если запустить изначально игру в режиме 'WindowMode', затем скрыть(hide) игру, то можно свободно работать с остальными приложениями. (То есть тут проблем не возникает), но если изначально запустить игру в режиме 'FullScreen', затем при помощи кнопки 'F11' поменять статус окна на 'WindowMode', затем скрыть(hide), и попытаться нажать вне окна, то окно игры тутже разворачивается. (3 раза повторив — игра закрывается).
P.S. -> Я уже пытаюсь решить эту проблему около недели(чуть больше). Читал достаточно много информации по поводу 'SetWindowPos', перехвата глобальных сообщений и т.д. Через 'SetWindowPos' к сажалению решить проблему не удалось =(
