How do I get the application data path in Windows using C++?
提问by Brian T Hannan
I looked all over the internet and there doesn't seem to be a decent solution that I could find. I want to be able to programmatically in C++ obtain the path "%ALLUSERSPROFILE%\Application Data" that explorer can translate into a real path.
我查看了整个互联网，似乎没有找到合适的解决方案。我希望能够在 C++ 中以编程方式获取资源管理器可以转换为真实路径的路径“%ALLUSERSPROFILE%\Application Data”。
Can I do this without relying on third-party code?
我可以在不依赖第三方代码的情况下做到这一点吗？

Use SHGetFolderPathwith CSIDL_COMMON_APPDATAas the CSIDL.
使用SHGetFolderPath与CSIDL_COMMON_APPDATA作为CSIDL。
TCHAR szPath[MAX_PATH];
if (SUCCEEDED(SHGetFolderPath(NULL, CSIDL_COMMON_APPDATA, NULL, 0, szPath)))
{
//....
}

Just to suppliment interjay's answer
只是为了补充 interjay 的回答
I had to include
shlobj.hto useSHGetFolderPath.Often you may need to read a file from appdata, to do this you need to use the
pathAppendfunction (shlwapi.his needed for this).
我必须包含
shlobj.h才能使用SHGetFolderPath.通常，您可能需要从 appdata 读取文件，为此您需要使用该
pathAppend函数（shlwapi.h为此需要）。
#include <shlwapi.h>
#pragma comment(lib,"shlwapi.lib")
#include "shlobj.h"
TCHAR szPath[MAX_PATH];
// Get path for each computer, non-user specific and non-roaming data.
if ( SUCCEEDED( SHGetFolderPath( NULL, CSIDL_COMMON_APPDATA, NULL, 0, szPath ) ) )
{
// Append product-specific path
PathAppend( szPath, _T("\My Company\My Product\1.0\") );
}
See herefor more details.

you can also read the value from the registry
您还可以从注册表中读取值
path = HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
路径 = HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
key = Common AppData
键 =通用应用数据
