列举Windows注册表项中的所有子键和值

我正在尝试编写一个Windows应用程序，该应用程序可以让我返回给定某个键的所有子键和值。我编写的代码似乎可以在给定键内提供子键，但不能正确枚举值;它成功地枚举了不带值的子键，并以选项卡树的形式返回结果。但是，在枚举值时，程序会为每个存在的值返回一个随机值(每次都是相同的随机值)，然后崩溃并出现调试错误。

它的预期输出基本上是:

(1) KEY
    (1) SUBKEY
    (1) SUBKEYWITHINSUBKEY
        Code: value1data
        Code: value2data
        Code: value3data
(2) SUBKEY
    (1) SUBKEYWITHINSUBKEY
(3) SUBKEY

…等等。

(1) KEY
(1) SUBKEY
    (1) SUBKEYWITHINSUBKEY
        Code: someValue
        Code: someValue
        Code: someValue

(…然后崩溃)

之后会出现以下错误:
"调试错误!"运行时检查失败#2 -变量'valNameLen'周围的堆栈已损坏。"

代码现在有点乱(我是一个Windows API新手)，但是如果有人能告诉我我做错了什么，或者以任何他们认为合适的方式批评我的编码风格，那将是伟大的。

谢谢!
