VARTYPE (Windows Embedded CE 6.0)

1/6/2010

This enumeration is used in VARIANT, TYPEDESC, OLE property sets, and safe arrays.

The enumeration constants listed in the following VARENUM section are valid in the vt member of a VARIANT structure.

Syntax

typedef unsigned short VARTYPE;
enum VARENUM {
  VT_EMPTY = 0, 
  VT_NULL = 1, 
  VT_I2 = 2, 
  VT_I4 = 3, 
  VT_R4 = 4, 
  VT_R8 = 5, 
  VT_CY = 6, 
  VT_DATE = 7, 
  VT_BSTR = 8, 
  VT_DISPATCH = 9, 
  VT_ERROR = 10, 
  VT_BOOL = 11, 
  VT_VARIANT = 12, 
  VT_UNKNOWN = 13, 
  VT_UI1 = 17, 
};
VT_RESERVED = 0x8000
VT_BYREF = 0x4000
VT_ARRAY = 0x2000
