Подскажите пожалуйста как избавится от нее.... Хотелось бы увидеть какой нибуть код или исходник который решает данную проблему! Заранее спасибо!
Я не слабо провозился с этим моментом на работе. WS_EX_TRANSPARENT не работал - что-то проглядывало из фона - какое-то другое окно с тем же родителем (чего только индусы не наворотят...). Единственное, что получилось - это прямой subclassing хэндла таб контрола и затем перед вызовом "оригинального" кода для WM_ERASEBKGND - вызвать ExcludeClipRect() API с прямоугольником полученным через TCM_ADJUSTRECT. Если время позволит - выложу пример кода.
вот так создаю главное окно Код (Text): mov wc.cbSize, sizeof wc mov wc.style,NULL mov wc.lpfnWndProc, offset WndProc mov wc.cbClsExtra, NULL mov wc.cbWndExtra, NULL push hInstance pop wc.hInstance mov wc.hbrBackground, COLOR_BTNFACE+1 mov wc.lpszMenuName, offset MenuName mov wc.lpszClassName, offset ProgClass INVOKE LoadIcon, NULL, IDI_APPLICATION mov wc.hIcon, eax mov wc.hIconSm, eax INVOKE LoadCursor, NULL, IDC_ARROW mov wc.hCursor, eax INVOKE RegisterClassEx, addr wc INVOKE CreateWindowEx, WS_EX_WINDOWEDGE, addr ProgClass,\ addr AppName, WS_OVERLAPPEDWINDOW or WS_CLIPCHILDREN or WS_CLIPSIBLINGS ,\ 100, 100, 1152, 687, NULL, NULL, hInstance, NULL mov hWnd, eax а так таб котрол Код (Text): invoke CreateWindowEx,0,OFFSET szClassTabControl,0,WS_CHILD or WS_VISIBLE or 1 or TCS_HOTTRACK or\ TCS_FOCUSNEVER,4,27,600,300, hWin,0,hInstance,0
