求助懂VB破解的高手，反编译出来后有个关键的字符串编码函数有点看不懂，帮我看看代码
[Visual Basic] 纯文本查看 复制代码 Private Sub Proc_14_6_47A070(arg_C, arg_10) '47A070
loc_0047A0BE: On Error Resume Next
loc_0047A0D7: var_C4 = Len(arg_C)
loc_0047A0EE: GoTo loc_0047A102
loc_0047A0F3: var_24 = var_24 + var_C0
loc_0047A0FF: var_24 = var_24+var_C0
loc_0047A102: ' Referenced from: 0047A0EE
loc_0047A10B: If var_24 > var_C4 Then GoTo loc_0047A282
loc_0047A161: var_8008 = AscW(CStr(Mid(arg_C, var_24, 1)))
loc_0047A16A: var_8008 = var_8008 + edx
loc_0047A173: var_6C = var_8008+edx
