MonthCal_GetMonthDelta

INT MonthCal_GetMonthDelta(
    HWND hwndMC
);

Retrieves the scroll rate for a month calendar control. The scroll rate is the number of months that the control moves its display when the user clicks a scroll button. You can use this macro or send the MCM_GETMONTHDELTA message explicitly.

• If the month delta was previously set using the MonthCal_SetMonthDelta macro, returns an INT value that represents the month calendar's current scroll rate. If the month delta was not previously set using the MonthCal_SetMonthDelta macro, or the month delta was reset to the default, returns an INT value that represents the current number of months visible.
