VARTYPE

VARTYPE is an enumeration type used in VARIANT, TYPEDESC, OLE property sets, and safe arrays. The enumeration constants listed below are valid in the vt field of a VARIANT structure.

typedef unsigned short VARTYPE;

enum VARENUM{

VT_EMPTY = 0, // Not specified

VT_NULL = 1, // Null

VT_I2 = 2, // 2-byte signed int

VT_I4 = 3, // 4-byte signed int

VT_R4 = 4, // 4-byte real

VT_R8 = 5, // 8-byte real

VT_CY = 6, // Currency

VT_DATE = 7, // Date

VT_BSTR = 8, // Binary string

VT_DISPATCH = 9, // IDispatch FAR*

VT_ERROR = 10, // SCODE

VT_BOOL = 11, // Boolean; True=-1, False=0

VT_VARIANT = 12, // VARIANT FAR*

VT_UNKNOWN = 13, // IUnknown FAR*

VT_UI1 = 17, // Unsigned char

.

. //Other constants that are not valid in VARIANTs

.

};

VT_RESERVED = (int) 0x8000

// By reference: a pointer to the data is passed

VT_BYREF = (int) 0x4000

VT_ARRAY = (int) 0x2000 // A safe array of the data is passed
