Call DDV_MinMaxMonth to verify that the time/date value in the month calendar control (CMonthCalCtrl) associated with refValue falls between refMinRange and refMaxRange.

void AFXAPI DDV_MinMaxMonth(
   CDataExchange* pDX,
   CTime& refValue,
   const CTime* refMinRange,
   const CTime* refMaxRange 
void AFXAPI DDV_MinMaxMonth(
   CDataExchange* pDX,
   COleDateTime& refValue,
   const COleDateTime* refMinRange,
   const COleDateTime* refMaxRange 


A pointer to a CDataExchange object. The framework supplies this object to establish the context of the data exchange, including its direction.


A reference to an object of type CTime or COleDateTime associated with a member variable of the dialog box, form view, or control view object. This object contains the data to be validated. MFC passes this reference when DDV_MinMaxMonth is called.


Minimum date/time value allowed.


Maximum date/time value allowed.
