如何读取和写入包含斜杠的键名中的数据?

[流水之风]

在注册表中有一些键名包含了反斜杠,如何从这些键名中读取和写入数据?请使用VB编写.

例如:
项名:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDlls
键名:C:\WINDOWS\system32\FM20CHS.DLL
值:1

有没有\不是关键，这些你查一下regopenkey等等就可以了。

十分感谢jennyvenus给的源码，现在已经解决了，原来是我自己的方法不对。

不太明白楼主的意思，正常的读取GetSetting和写入SaveSetting会有问题吗？
