Up-Down Control Styles

This section lists the styles used when creating up-down controls.

ConstantDescription
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 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_HOTTRACK

Causes the control to exhibit "hot tracking" behavior. That is, it highlights the UP ARROW and DOWN ARROW on the control as the pointer passes over them. This style requires Windows 98 or Windows 2000. If the system is running Windows 95 or Windows NT 4.0, the flag is ignored. To check whether hot tracking is enabled, call SystemParametersInfo.

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.
