我的想法是这样的： 在一个程序中，我希望通过代码直接可以更改注册表某个值，比如一个可执行文件，其注册表值：0表示可用，1表示不可用， 程序中可以更改这个值。 希望可以通过回复方式把代码置上，先行谢过。

好像在我们VB论坛里也有关于注册表的操作，但觉得太麻烦了。 如果觉得论坛回复麻烦的话，可以发送到我的邮箱 mwj_425@163.com

我给一个操作注册表的类

Public Const ERROR_SUCCESS = 0& Public Const APINULL = 0&

Const REG_SZ = 1 ' Unicode nul terminated string Const REG_BINARY = 3 ' Free form binary Public Const HKEY_CURRENT_USER = &H80000001 Public Const HKEY_LOCAL_MACHINE = &H80000002

Public ReturnCode As Long
