3/28/2014

This macro sets the display for days in all months that are currently visible within a month calendar control.

Syntax

BOOL MonthCal_SetDayState(
  HWND hwndMC, 
  INT iMonths, 
  LPMONTHDAYSTATE lpDayStateArray 
);

Parameters

  • hwndMC
    Handle to a month calendar control.
  • iMonths
    INT value that indicates how many elements are in the array that lpDayStateArray points to.
  • lpDayStateArray
    Long pointer to an array of MONTHDAYSTATE values that define how the month calendar control will draw each day in its display.

Return Value

Nonzero if successful. If the macro fails, it returns zero.

Remarks

The array at lpDayStateArray must contain as many elements as the value returned by the following macro.

MonthCal_GetMonthRange(hwndMC, GMR_DAYSTATE, NULL);

The preceding macro returns the total number of months that are in complete or partial view within the month calendar's display.

Keep in mind that the array at lpDayStateArray must contain MONTHDAYSTATE values that correspond with all months currently in the control's display, in chronological order. This includes the two months only partially displayed before the first month and after the last month.
