Sets the minimum and maximum positions (range) for an up-down control.
- Must be zero.
The LOWORD is a short that specifies the maximum position for the up-down control, and the HIWORD is a short that specifies the minimum position. Neither position can be greater than the UD_MAXVAL value or less than the UD_MINVAL value. In addition, the difference between the two positions cannot exceed UD_MAXVAL.
No return value.
The maximum position can be less than the minimum position. Clicking the up arrow button moves the current position closer to the maximum position, and clicking the down arrow button moves toward the minimum position.
