Control styles for up-down controls supported by Windows CE are described in the following table.
| Style | Description |
|---|---|
| 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 is 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 process the UP ARROW and DOWN ARROW keys on the keyboard. |
| UDS_AUTOBUDDY | Automatically elects the previous window in the Z order as the up-down control's buddy window. In Windows CE, the window must be an edit control. |
| UDS_HORZ | Causes the up-down control's arrows to point left and right instead of up and down. |
| UDS_NOTHOUSANDS | Refrains from inserting 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 end or beginning of the range. |
