Get the path to My Documents with Inno Setup

Is it possible to retrieve the path to My Documents folder with Inno setup?

I tried to retrieve the path via registry

RegQueryStringValue(HKCU, 'SOFT开发者_如何学JAVAWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders', 'Personal', path);

But it returned: %USERPROFILE%\Mina dokument. When I tried to use it as install path it didn't work.

Inno Setup supports the Shell Folder Constants {userdocs} and {commondocs} for this job.
