Description
Specifies the date, date-time, Duration or Period type values.
Members
dwValueType : Specifies the value type. AEEVVALUE_DATE specifies Date type AEEVVALUE_DATE_TIME specifies Date-Time type AEEVVALUE_PERIOD specifies Period type. AEEVVALUE_DURATION specifies duration type.bIsDuration : 1 specifies duration else date-time type. This is valid only if Value is period type (dwValueType = AEEVVALUE_DATE_TIME).bIsPriorDuration : Specifies whether the duration value is prior or not. This will be used for Trigger related properties.bIsUTC : It will be set to 1 if the values (dwValue1 & dwValue2) are in UTC format.dwValue1 : Specifies the value in Julian Seconds.
dwValue2 : Specifies the end date-time in Period type values seperated by solidus character from date-start value (19960403T020000Z/19960403T040000Z) in Julian Seconds. Julian seconds corresponds to end datetime (19960403T040000Z) will be filled.sDuration : Specifies the duration in Period type values seperated by solidus character from date-start value or Trigger related values. This is valid only if dwValueType = AEEVVALUE_PERIOD and bIsDuration = 1 or dwValueType = AEEVVALUE_DURATION and bIsDuration = 1;

If the value is Date type:
Ex: RDATE:19970406 then :
dwValueType = AEEVVALUE_DATE, bIsDuration = 0;
dwValue1 will be filled with julian seconds corresponds to RDATE value.
If the value is Date-Time type:
Ex: DTSTART:19980118T230000 then :
dwValuetype = AEEVVALUE_DATE_TIME, bIsDuration = 0;
dwValue1 will be filled with seconds corresponds to DTSTART value.
Ex: TRIGGER;VALUE=DATE-TIME:19970317T133000Z
dwValuetype = AEEVVALUE_DATE_TIME, bIsDuration = 0; bIsUTC = 1;
dwValue1 will be filled with julian seconds corresponds to TRIGGER value.
If the value is Duration type:
Ex: TRIGGER:-PT30M
dwValuetype = AEEVVALUE_DURATION, bIsDuration = 1;
bIsPriorDuration = 1;
m_JD structure will be filled corresponds to TRIGGER duration value.
If the value is Period type:
Ex; RDATE;VALUE=PERIOD:19960403T020000Z/19960403T040000Z then:
dwValueType = AEEVVALUE_PERIOD, bIsDuration = 0; bIsUTC = 1;
dwvalue1 will be filled with julian seconds corresponds to RDATE start
date-time value.
dwValue2 will be filled with julian seconds corresponds to RDATE end
date-time value.
Ex: RDATE;VALUE=PERIOD:19960404T010000Z/PT3H then:
dwValueType = AEEVVALUE_PERIOD, bIsDuration = 1;
dwvalue1 will be filled with seconds corresponds to RDATE start date-time
value.
m_JD structure will be filled corresponds to RDATE duration value.
dwValue2 will be considered only if dwValueType = AEEVVALUE_PERIOD &
bIsDuration = 0;
m_JD will be considered only if
dwValueType = AEEVVALUE_PERIOD & bIsDuration = 1 or
dwValuetype = AEEVVALUE_DURATON & bIsDuration = 1;
It always assumes that dwValue1 and dwValue2 are in same format.
If the user wants to generate property with UTC time format then bIsUTC
should be set to 1 and dwValue1 filled with corresponding seconds.
Structure To get DTSTART:19970301T200000Z buffer is:
bIsUTC = 1, dwValue1 filled with seconds all other filelds are zero.
