UDM_GETPOS message
Retrieves the current position of an up-down control with 16-bit precision.
Parameters
-
wParam
- Must be zero.
-
lParam
- Must be zero.
Return value
If successful, the HIWORD is set to zero and the LOWORD is set to the control's current position. If an error occurs, the HIWORD is set to a nonzero value.
Remarks
When processing this message, the up-down control updates its current position based on the caption of the buddy window. The up-down control returns an error if there is no buddy window or if the caption specifies an invalid or out-of-range value. Also, an error flag is set in the HIWORD of the return if the control is created without the UDS_SETBUDDYINT style, even though it returns a valid position value in the LOWORD of the return.
If 32-bit values have been enabled for an up-down control with UDM_SETRANGE32, this message returns only the lower 16 bits of the position. To retrieve the full 32-bit position, use UDM_GETPOS32.
