Parameters

NameDescription
vtNewThe new variant type.
wFlagsVARIANT_NOVALUEPROP : Prevents the function from coercing an object to a fundamental type by getting the Value property. Applications should set this flag only if necessary, because it makes their behavior inconsistent with other applications.
VARIANT_ALPHABOOL : Converts a VT_BOOL value to a string containing either "True" or "False".
VARIANT_NOUSEROVERRIDE : For conversions to or from VT_BSTR, passes LOCALE_NOUSEROVERRIDE to the core coercion routines.
VARIANT_LOCALBOOL : For conversions from VT_BOOL to VT_BSTR and back, uses the language specified by the locale in use on the local computer.

Return value

Returns S_OK (0) or an HRESULT error code.
