SetClassLong(hwnd, GCL_HBRBACKGROUND, (LONG)CreateSolidBrush(RGB(0, 191, 255)));

Код


::InvalidateRect(hwnd,NULL,TRUE);

Цитата(SetClassLong @ MSDN)

Use the SetClassLong function with care. For example, it is possible to change the background color for a class by using SetClassLong, but this change does not immediately repaint all windows belonging to the class.

Почему тогда модификация с целью отображения иконки в сис. меню "прокатывает"?

Цитата(S.A.G. @ 22.7.2009, 20:27

)

Если я затаскиваю окно за границы экрана, сворачиваю, etc., и потом все возвращаю, то почему окно не перерисовывается с использованием новой кисти?

Цитата(S.A.G. @ 22.7.2009, 20:27

Хотел тебе еще +1 сделать, но какой-то прАтивный скрипт не разрешил.

Цитата(S.A.G. @ 22.7.2009, 20:27

)

InvalidateRect() НЕ помог. Опасения были.

чтобы найти решающую, надо "смотреть в код"
