MonthCal_GetMonthRange macro

Retrieves date information (using SYSTEMTIME structures) that represents the high and low limits of a month calendar control's display. You can use this macro or send the MCM_GETMONTHRANGE message explicitly.

Syntax

INT MonthCal_GetMonthRange(
  HWND hwndMC,
  DWORD dwFlag,
  LPSYSTEMTIME lprgSysTimeArray
);

Parameters

hwndMC

Type: HWND

Handle to a month calendar control.

dwFlag

Type: DWORD

Value specifying the scope of the range limits to be retrieved. This value must be one of the following:

Value	Meaning
GMR_DAYSTATE	Include preceding and trailing months of visible range that are only partially displayed.
GMR_VISIBLE	Include only those months that are entirely displayed.

 

lprgSysTimeArray

Type: LPSYSTEMTIME

Pointer to a two-element array of SYSTEMTIME structures that will receive the lower and upper limits of the scope specified by dwFlag. The lower and upper limits are placed in lprgSysTimeArray[0] and lprgSysTimeArray[1], respectively. The time members of these structures will not be modified. This parameter must be a valid address and cannot be NULL.

Return value

Returns an INT value that represents the range, in months, spanned by the two limits returned at lprgSysTimeArray.
