RE: [GD-Windows] Security/access when writing to registry

[Andrew G. <And...@ho...>]

There's another important thing in this area to remember as well. Depending
on their permissions users might not have write permissions to the directory
the game is stored in. It's now recommended that you ensure persistantdata
is stored in folders that users have guaranteed access to, and use
SHGetFolderPath to retrieve this path with the correct identifier. In the
case of application data it would be CSIDL_COMMON_APPDATA, or for user
specific settings you would use CSIDL_APPDATA.

This is going to become a real issue now that XP is around and allows people
to restrict access like this. We've already had one bug report from a
previous project because our game relied on write access to it's install
folder, and little Johhny's dad had locked him off from modifying the
Program Files subtree.

There was an excellent presentation from Mike Burrows at Meltdown this year
about how to write well behaved Windows apps taking these and other aspects
into account. It's now online and well worth a read.
