Members
| Member name | Description | |
|---|---|---|
| VT_ARRAY | An array of variants. | |
| VT_BLOB | An arbitrary block of memory. | |

| 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_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_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. |
Remarks
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.
