VB6如何利用API函数读、写注册表中的多字节的二进制binary值？

to dbcontrols(泰山__抛砖引玉):这个“注册表访问.bas”中的getkeyvalue（）函数，得不到我上面说的二进制数值。对于读取string或Dword值我知道怎么读，但就是不知道怎么读出来？我用的方法是：msgbox getkeyvalue(HKEY_CURRENT_USER, "Software\Microsoft\Windows\CurrentVersion\Policies\Explorer", "NoDriveTypeAutoRun")

读取注册表的模块和类我手头有很多，但好像都不能读出多字节的二进制binary数值！！！！！！！！！！！！！！

'引用 Windows Script Host Model
Dim x As New IWshRuntimeLibrary.WshShell
Dim buffer0 As Variant
'buffer0 即为二进制流
buffer0 = x.RegRead("HKEY_CLASSES_ROOT\.UDL\ShellNew\Data")Dim i As Long
Dim buffer() As Byte
ReDim buffer(LBound(buffer0) To UBound(buffer0)) As Byte
'将 buffer0 复制为 buffer
For i = LBound(buffer) To UBound(buffer)
buffer(i) = buffer0(i)
Debug.Print "&H" & VBA.Hex(buffer(i))
Next i
