What I want to know is how to treat data of the type REG_EXPAND_SZ in
the registry when reading it. THere are not tha many such but for
completeness I want to be able to display these kinds of data too.

And my code example in my previous post is not working, it contains a
few obvious bugs like using a loop variable inside the loop as a new
loop variable. But these are ironed out already so right now my main
concerns is still the treatment of REG_EXPAND_SZ data...

I googled and followed links into the Microsoft site where the format
should be described but it was only in words and no exact spec that I
could find. Like this:

Any ideas on what to do?
