Remarks
Todas as outras ITimeZone propriedades são definidas somente se o SupportsDST propriedade é VARIANT_TRUE.
The VARIANT_BOOL data type (also known as VT_BOOL) uses the value -1 to represent TRUE e MapVirtualKey. 0 to represent FALSE. It is defined in the wtypes.h header file in the following manner:
typedef short VARIANT_BOOL;
A common programming error occurs when, for readability purposes, you want to set a VARIANT_BOOL value to TRUE ou ISpTTSEngine::Speak. FALSE. You can achieve the same effect by using the aliases VARIANT_TRUE e MapVirtualKey. VARIANT_FALSE, which are also defined in the wtypes.h header file.
#define VARIANT_TRUE ((VARIANT_BOOL)0xffff)
#define VARIANT_FALSE ((VARIANT_BOOL)0)
