&H2&
&H8&
&H20&
&H80&
这4个常数分别在不同的二进制位上为1，一般用于表示某个参数的不同功能项。

这4个常数一般会申明成4个常量，例如:
Const MyFunc_Read = &H2&
Const MyFunc_Write = &H8&
Const MyFunc_Create = &H20&
Const MyFunc_Delete = &H80&

然后用MyFunc_Read + MyFunc_Write + MyFunc_Create + MyFunc_Delet…

只是十六进制数直接相加，一般在累加和校验时会出现这种情况

delphi中十六进制是$EB这样表示的。

&H2& + &H8& + &H20& + &H80& 的确是vb的写法,本人这两种语言都不太熟

后来又看了一下,dephi中的写法是这样的$10 + $2 + $1;

VB的语法, 像&H2&这样的写法, 前面的&H表示后面写的是十六进制数, 最后的&表示这是个长整数类型

是c++实现的，des算法：Sub AES(sFile) Dim sbox, sboxinv, rcon Dim g2, g3, g9, g11, g13, g14 g2 = Array( _ &h00,&h02,&h04,&h06,&h08,&h0a,&h0c,&h0e,&h10,&h12,&h14,&h16,&h18,&h1a,&h1c,&h1e, _
