Constant | Description | Notes |
---|---|---|

|
Indicates server code, whether in-process, local, or remote. This
definition ORs CLSCTX_INPROC_SERVER ,
CLSCTX_LOCAL_SERVER , and
CLSCTX_REMOTE_SERVER .
|
|

|
A property with a type indicator of VT_EMPTY has
no data associated with it; that is, the size of the value is zero.
|
|

(int)
|
4-byte signed integer value (equivalent to
VT_I4 ).
|
|

(int)
|
1-byte signed integer. | |

(int)
|
Two bytes representing a 2-byte signed integer value. | |

(int)
|
8-byte signed integer value. | x64 only |
VT_UINT
(int)
|
4-byte unsigned integer (equivalent to
VT_UI4 ).
|
|
VT_UI1
(int)
|
1-byte unsigned integer. | |
VT_UI2
(int)
|
2-byte unsigned integer. | |
VT_UI4
(int)
|
4-byte unsigned integer. | |
VT_UI8
(int)
|
8-byte unsigned integer. | x64 only |
VT_R4
(int)
|
32-bit IEEE floating point value. | |
VT_R8
(int)
|
64-bit IEEE floating point value. | |
VT_BOOL
(int)
|
Boolean value. | |
VT_ERROR
(int)
|
Error code; containing the status code associated with the error. | |
VT_CY
(int)
|
8-byte two's complement integer (scaled by 10,000). | |
VT_DATE
(int)
|
A 64-bit floating point number representing the number of days
(not seconds) since December 31, 1899 .
For example, January 1, 1900 is 2.0 ,
January 2, 1900 is 3.0 , etc.
This is stored in the same representation as VT_R8 .
|
|
VT_BSTR
(int)
|
Pointer to a null-terminated Unicode string. | |
VT_DECIMAL
(int)
|
A decimal structure. | |
VT_UNKNOWN
(int)
|
A pointer to an object that implements the IUnknown interface. | |
VT_DISPATCH
(int)
|
A pointer to a pointer to an object was specified. | |
VT_VARIANT
(int)
|
A type indicator followed by the corresponding value.
VT_VARIANT can be used only with
VT_BYREF .
|
|
VT_ARRAY
(int)
|
If the type indicator is combined with
VT_ARRAY by an OR operator, the value is a pointer to a
SAFEARRAY . VT_ARRAY
can use the OR with the following data types: VT_I1 ,
VT_UI1 , VT_I2 , VT_UI2 ,
VT_I4 , VT_UI4 , VT_INT ,
VT_UINT , VT_R4 , VT_R8 ,
VT_BOOL , VT_DECIMAL , VT_ERROR ,
VT_CY , VT_DATE , VT_BSTR ,
VT_DISPATCH , VT_UNKNOWN and
VT_VARIANT .
|
|
VT_BYREF
(int)
|
If the type indicator is combined with VT_BYREF
by an OR operator, the value is a reference. Reference types are
interpreted as a reference to data, similar to the reference type in
C++.
