A scroll bar control can have a number of styles to control the orientation and position of the scroll bar. You specify the styles that you want when you call the CreateWindowEx function to create a scroll bar control. Some of the styles create a scroll bar control that uses a default width or height. However, you must always specify the x- and y-coordinates and the other dimensions of the scroll bar.
Scroll bar styles supported by Windows CE are described in the following table.
| Style | Description |

| SBS_BOTTOMALIGN | Aligns the bottom edge of the scroll bar with the bottom edge of the rectangle defined by the CreateWindowEx parameters x, y, nWidth, and nHeight. The scroll bar has the default height for system scroll bars. Use this style with the SBS_HORZ style. |
