public enum VariantType

Member nameDescription
VT_ARRAY

An array of variants.

VT_BLOB

An arbitrary block of memory.

VT_BLOB_OBJECT

An arbitrary block of memory representing an object.

VT_BOOL

A value representing true (-1) or false (0).

VT_BSTR

A string.

VT_BYREF

A reference to an object.

VT_CARRAY

A C-style array (an array of pointers).

VT_CF

A value specifying a clipboard format.

VT_CLSID

A GUID for a class (a CLSID).

VT_CY

A Currency value (fixed decimal point value stored in 64-bits).

VT_DATE

A DATE object.

VT_DECIMAL

A decimal number stored as a string.

VT_DISPATCH

An object that implements the IDispatch interface.

VT_EMPTY

An empty variant.

VT_ERROR

An error code (typically returned from a Win32 function).

VT_FILETIME

A FILETIME value.

VT_HRESULT

An HRESULT or COM return value.

VT_I1

A 1 byte (8-bit) signed integer.

VT_I2

A 2 byte (16-bit) signed integer.

VT_I4

A 4 byte (32-bit) signed integer.

VT_I8

An 8 byte (64-bit) signed integer.

VT_ILLEGAL

Represents an illegal variant type.

VT_ILLEGALMASKED

A bit mask to isolate valid variant types.

VT_INT

A generic integer (typically a 32-bit value).

VT_LPSTR

A pointer to a null-terminated ANSI string.

VT_LPWSTR

A pointer to a null-terminated wide character (Unicode) string.

VT_NULL

A null value.

VT_PTR

A generic pointer.

VT_R4

A 4 byte real number, also known as a float.

VT_R8

An 8 byte real number, also known as a double.

VT_RESERVED

Reserved for future use.

VT_SAFEARRAY

An array that is guaranteed to be at least empty (that is, it is never a null value).

VT_STORAGE

Name of the storage.

VT_STORED_OBJECT

A storage object.

VT_STREAM

A stream of bytes.

VT_STREAMED_OBJECT

A stream that contains an object.

VT_TYPEMASK

A bit mask to isolate valid variant types.

VT_UI1

A 1 byte (8-bit) unsigned integer.

VT_UI2

A 2 byte (16-bit) unsigned integer.

VT_UI4

A 4 byte (32-bit) unsigned integer.

VT_UI8

An 8 byte (64-bit) unsigned integer.

VT_UINT

A generic unsigned integer (typically 32-bits).

VT_UNKNOWN

An object implementing the IUnknown interface.

VT_USERDEFINED

A user-defined blob.

VT_VARIANT

A reference to a variant object.

VT_VECTOR

An array with a leading count value.

VT_VOID

A C-style void type.

The values here correspond to a standard variant type but these are used specifically with the Variant structure in an MPF language service. The language service is interested in only one variant type, VT_UI2, which is a 2 byte unsigned integer representing a Unicode character.
