RegOpenKeyEx 错误 [英] Error with RegOpenKeyEx

问题描述

我正在使用 Code::blocks 编写一个更改注册表的程序，但是当我调用时

I'm using Code::blocks to write a program that changes the registry, but when I call

RegOpenKeyEx (HKEY_LOCAL_MACHINE,
              "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunOnce", 
               0, 
               KEY_ALL_ACCES | KEY_WOW64_64KEY, 
               &key);

代码块返回

`KEY_WOW64_64KEY' 未声明(首次在该函数中使用)

`KEY_WOW64_64KEY' undeclared (first use in this function)

我添加了 #include 但它仍然不起作用.
谢谢:)

I had add #include <windows.h> but it still doesn't work.
Thanks :)

推荐答案

您需要定义 XP 或更高版本的 Windows 目标版本才能访问它.您的目标可能是 Windows 2000.

You need to define a Windows target version of XP or greater to have access to this. You are probably targeting Windows 2000.

在 targetver.h(或任何你定义 _WIN32_WINNT 的地方)你需要这个:

In targetver.h (or wherever you define _WIN32_WINNT) you need this:

#define _WIN32_WINNT 0x0501 //targets XP or later
