win32utils devel - Sep 2008 - Getting virtual folder information

Hi,

One of the problems with SHGetFolderPath is that it doesn''t work for
virtual folders. I _think_ we can get it with SHGetFolderLocation, but
I''m not positive, as I''m having a bit of trouble making it
work.

Any ideas on how to get, say, the value of CSIDL_DRIVES? I mean, it
should be "My Computer", but I want to get it programmatically.

Thanks,

Dan

PS - I''ve added SHGetFolderLocation to Windows::Shell in CVS.

require ''windows/shell''
include Windows::Shell

pidl = 0.chr * 4
SHGetSpecialFolderLocation(0, CSIDL_DRIVES, pidl)
# size of SHFILEINFO is 692 bytes
info = 0.chr * 692
# 0x200 says get display name, 0x8 says PIDL, not path.
SHGetFileInfo(pidl.unpack(''L'').first,0, info ,692,0x208)
folder = info[12..-1].strip
