Работа со ScrollBar

[Maray]

Добрый день!

Помогите, пожалуйста. Создала Slider.

CreateWindowEx(0, TEXT("scrollbar"), NULL, WS_CHILD | WS_VISIBLE, 270, 260, 200, 40, hwnd, (HMENU)IDC_SCROLLBAR, lpCreateStruct->hInstance, NULL);

Помогите, пожалуйста организовать работу с ним. Мне для примера. Любая работа. Например, пусть под scrollBar находится текстовое поле, и при движении scrollbar вправо будет увеличиваться число от 0 до 100

Поискала в Интернете, нашла пример и переделала под себя. Но не до конца. Помогите, пожалуйста.
Нужно убрать с формы справа черную часть, и поставить Scroll в правую сторону, чтобы он находился там.
