Since my application will be deployed on all kinds of Windows OSes i need to be able to get the folder 100% percent of the time. The question is how do you do it in C++? Since i don't know the the exact Windows OS it could be XP,Vista or 7 and most importantly i don't know what the Username is.

推荐答案

为了与所有版本的Windows最大兼容，您可以使用 SHGetFolderPath 函数。

它要求您指定 CSIDL 值，以获取要检索其路径的文件夹。对于应用程序数据文件夹，这将是 CSIDL_APPDATA 。

For maximum compatibility with all versions of Windows, you can use the SHGetFolderPath function.
It requires that you specify the CSIDL value for the folder whose path you want to retrieve. For the application data folder, that would be CSIDL_APPDATA.

在Windows Vista及更高版本中，您应该使用 SHGetKnownFolderPath 函数，这要求您指定文件夹的 KNOWNFOLDERID 值。同样，对于应用程序数据文件夹，适当的值为 FOLDERID_RoamingAppData 。

On Windows Vista and later, you should use the SHGetKnownFolderPath function instead, which requires that you specify the folder's KNOWNFOLDERID value. Again, for the application data folder, the appropriate value is FOLDERID_RoamingAppData.

要使用这些函数C ++应用程序，您需要包括 shlobj.h 。

To use either of these functions from your C++ application, you'll need to include shlobj.h.
