blocks|key|1038402|text|你可能在找CSIDL_COMMON_APPDATA。IIRC，这也应该是一个很好的选择，如果你去任何Windows标志认证。如果它不适合您的需求，请检查MSDN上的此链接，您应该能够找到最适合您的需求。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1038403|祝好运。|1038404|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/bb762494(VS.85).aspx)^0|24|9|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

You're probably looking for CSIDL_COMMON_APPDATA. IIRC that should also be a good choice should you go for any of Windows logo certifications. In case it doesn't fit your requirements, check <a href="http://msdn.microsoft.com/en-us/library/bb762494(VS.85).aspx" rel="nofollow noreferrer">this link on MSDN</a>, you should be able to find the best fit for your needs there. 
Good luck.

blocks|key|1015675|text|您不能仅仅使用一个固定的目录名，例如c:\FixedDataForYourProgram|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1015676|我们在XP上这样做。我没有在Vista/Win7+7上以编程的方式尝试这一点，但是作为Vista上的标准用户登录，我在root下创建一个目录没有问题。|1015677|我相信这违反了各种规则，但很简单。我喜欢简单。|1015678|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Can you not just use a fixed directory name, e.g. c:\FixedDataForYourProgram

We do this on XP. I've not tried this programmatically on Vista/Win7, but logged in as a standard user on Vista I have no problem creating a directory under root.

I'm sure this breaks all sorts of rules, but it is simple. I like simple.

blocks|key|2541918|text|如果您认为CSIDL_COMMON_APPDATA不合适(也许CSIDL_COMMON_APPDATA是一个很好的默认设置，但您希望管理员能够更改位置)，您可以让安装程序向HKLM\SOFTWARE\<your+app+subkey>写入一些东西，该HKLM\SOFTWARE\<your+app+subkey>指示将保存数据的公共目录的所需路径。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2541919|将指针放置在HKLM注册表中的另一种方法是在程序目录中有一个配置文件，该文件具有指向共享目录的指针。根据定义，程序目录必须由安装程序写，由管理员(可能负责修改配置)写，用户可以读。因此，标准用户可以读取一个众所周知的位置(一个HKLM子键或程序目录中的一个配置文件)，以获得一个指向所有标准用户可写目录的指针。|2541920|任何设置公共目录(安装程序或配置模块)的内容都需要确保公共目录的ACL为标准用户写入设置了适当的设置。|2541921|entityMap^0|5|K|V|K|2E|V|3H|V|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]|$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|V|8|@]|D|@]|E|$]]|$1|J|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|K|$]]

If you decide that <code>CSIDL_COMMON_APPDATA</code> isn't appropriate (maybe <code>CSIDL_COMMON_APPDATA</code> is a good default, but you want the administrator to be able to change the location) you can have the installer write something to an <code>HKLM\SOFTWARE\&lt;your app subkey&gt;</code> that indicates the desired path for the common directory that will hold the data.

An alternative to placing the pointer in the HKLM registry is to have a config file that resides in the program directory which has a pointer to the shared directory. By definition the program directory must writable by the installer, it's writable by administrators (who might be responsible for modifying the configuration), and it's readable by users. So a standard user can read a well-known location (either an HKLM sub-key or a config file in the program directory) to get a pointer to a directory that's writable by all standard users.

Whatever sets up the common directory (the install program or the configuration module) will need to make sure the common directory's ACL is set appropriately for standard user writes.

in my application I need to store settings that are 'global' (i.e. not user specific) in a known and predictable location.

I want the application to be able to be run from anywhere (as a standard user, NOT administrator), including multiple copies from different locations and be able to read and write the saved config files.

The data needs to have read and write access granted for ALL standard users, not just one.

With that in mind, the four options noted here are inappropriate:
<a href="http://msdn.microsoft.com/en-us/library/bb206295(VS.85).aspx#ID0E1BA" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/bb206295(VS.85).aspx#ID0E1BA</a>

So what are my alternatives?

My application is written in C++ and for Windows only. I need to support Windows XP and above.

Thanks.

EDIT:

To clarify, ignore race conditions caused by multiple instances. This question is solely to do with WHERE TO STORE THE DATA. I can't see anywhere suitable that is:

<ol>
<li>Predictable (e.g. %APPDATA%\Foo is a 'predictable' path, but unfortunately user-specific)</li>
<li>Global (e.g. %PROGRAMDATA%\Foo is a global path but unfortunately only the creating user has write-access)</li>
<li>Accessible (a standard user needs to be able to create new files in the given directory, this applies to all users on the system)</li>
</ol>

Saving 'global' data as a standard user?
