推荐答案

如果在cmd控制台中使用 set 命令，则此set命令仅对您当前的控制台和您从该控制台启动的其他控制台/程序。但是还有一个 setx 命令，它为当前控制台窗口设置控制台变量并改变全局设置！我不能告诉你什么是支持此命令的最低Windows版本，但在我的windows7上它存在。有关 setx 命令的更多信息，请打开cmd控制台并发出setx /？命令。



不要手动编辑注册表，不要浪费时间探索这些变量，因为你可以轻易地破坏你的窗口，这些值可能只能起作用在某些Windows版本上。这次投资学习有用的东西。你可以学到很多东西，所以要仔细选择！

If you use the set command in a cmd console then this set command has effect only on your current console and the other consoles/programs that you start from that console. BUT there is a setx command too that sets the console variable for the current console window and alters the global settings too!!! I can not tell you what is the lowest windows version that supports this command but on my windows7 it is present. For more on the setx command open a cmd console and issue the "setx /?" command.

Don''t edit the registry manually and don''t waste your time exploring these variables as you can easily wreck your windows and the values may work only on some windows versions. Invest this time in learning something useful. There are an infinite number of things you can learn so choose from them carefully!

正如Richard MacCutchan所说，你需要告诉我们你是什么正在努力做到。

i猜这些可能对你有帮助：

EnvironmentVariableTarget Enumeration [ ^ ]

GetEnvironmentVariable function [ ^ ]



由于您使用GetEnvironmentVariable收到的值可能不是当前值，因此最好直接从注册表中读取值

然后你可以使用RegOpenKeyEx（...）和RegQueryValueEx（...）函数



也 MSDN示例 [ ^ ]显示一些代码。



hope这有帮助。

as Richard MacCutchan has said, you need to tell us what you are trying to do.
i guess these might help you :
EnvironmentVariableTarget Enumeration[^]
GetEnvironmentVariable function[^]

Since the values you receive with GetEnvironmentVariable may not be the current ones it''ll be better to read the values directly from the registry
then you might use RegOpenKeyEx(...) and RegQueryValueEx(...) functions

also MSDN Examples[^] shows some code .

hope this helps .
