The following window styles are used with up-down controls.
| UDS_ALIGNLEFT | Positions the up-down control next to the left edge of the buddy window. The buddy window is moved to the right and its width decreased to accommodate the width of the up-down control. |
| UDS_ALIGNRIGHT | Positions the up-down control next to the right edge of the buddy window. The width of the buddy window is decreased to accommodate the width of the up-down control. |
| UDS_ARROWKEYS | Causes the up-down control to increment and decrement the position when the UP ARROW and DOWN ARROW keys are pressed. |
| UDS_AUTOBUDDY | Automatically selects the previous window in the Z order as the up-down control's buddy window. |
| UDS_HORZ | Causes the up-down control's arrows to point left and right instead of up and down. |
| UDS_NOTHOUSANDS | Does not insert a thousands separator between every three decimal digits. |
| UDS_SETBUDDYINT | Causes the up-down control to set the text of the buddy window (using the WM_SETTEXT message) when the position changes. The text consists of the position formatted as a decimal or hexadecimal string. |
| UDS_WRAP | Causes the position to "wrap" if it is incremented or decremented beyond the ending or beginning of the range. |
