The UDM_SETRANGE message sets the minimum and maximum positions (range) for an up-down control.
UDM_SETRANGE
wParam = 0;
lParam = (LPARAM) MAKELONG((short) nUpper, (short) nLower);
Parameters
nUpper and nLower
Maximum position and minimum position for the up-down control. 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.
Return Values

Remarks
The maximum position can be less than the minimum position. Clicking the up arrow moves the current position closer to the maximum position, and clicking the down arrow moves towards the minimum position.
