Re: [boost] [interprocess] Different processes accessing shared memory in different locations

if shared documents folder is not found, then the temporary path is used. The shared documents folder is found in the registry in the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Common AppData

That's the wrong way to do it. You should instead call either SHGetKnownFolderPath (on Vista+) or SHGetFolderPath (on -XP). Don't forget to pass the flag that requests creation of the folder if it doesn't already exist.
