VARIANT类型变量的vt值,得以确认:

     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_DECIMAL = 14,

     VT_I1 = 16,

     VT_UI1 = 17,

     VT_UI2 = 18,

     VT_UI4 = 19,

     VT_I8 = 20,

     VT_UI8 = 21,

     VT_BLOB_OBJECT = 70,

     VT_CF = 71,

     VT_CLSID = 72,

     VT_BSTR_BLOB = 0xfff,

     VT_VECTOR = 0x1000,

     VT_ARRAY = 0x2000,

     VT_BYREF = 0x4000,
