The IsDaylightAbsoluteDateproperty retrieves a value that indicates whether DaylightDateis Absolute or Relative.

Syntax 

HRESULT get_IsDaylightAbsoluteDate(
   VARIANT_BOOL * 
pfAbsolute
);

Parameters

pfAbsolute

[out] Reference to the Boolean flag. VARIANT_TRUEwhen DaylightDateis Absolute. For information about the VARIANT_BOOLtype, see the union member of the PROPVARIANTstructure.

Return Value

This method returns the standard values E_INVALIDARG, E_OUTOFMEMORY, E_UNEXPECTED, and E_FAIL, as well as the following:

S_OK

The method completed successfully.

Remarks

IsDaylightAbsoluteDateis undefined if SupportsDSTis VARIANT_FALSE.

The VARIANT_BOOLdata type (also known as VT_BOOL) uses the value -1 to represent TRUEand 0 to represent FALSE. It is defined in the wtypes.hheader file in the following manner:

Copy Code 
typedef short 
VARIANT_BOOL;

A common programming error occurs when, for readability purposes, you want to set a VARIANT_BOOLvalue to TRUEor FALSE. You can achieve the same effect by using the aliases VARIANT_TRUEand VARIANT_FALSE, which are also defined in the wtypes.hheader file.

Copy Code 
#define 
VARIANT_TRUE  ((VARIANT_BOOL)0xffff)
#define 
VARIANT_FALSE ((VARIANT_BOOL)0)

Requirements

Header pimstore.h
Library Pimstore.lib
Windows Embedded CE Windows CE 2.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
