Adding a dll function to QM

[ldarrambide]

Thanks for detailed answer.

Now i'm quite perplex, as I wanted to adapt QM ChangeFolderIcon, as
MSDN documentation seems to say that SHGetSetFolderCustomSettings is somehow obsolete and deprecated.
see http://msdn.microsoft.com/en-us/library/...85%29.aspx
I stumbled upon a document giving the way to do the same thing in "modern" way.

Actually my function is now working (returns 1 and no more 0) but
directory does not become system as supposed to.

I'm afraid all that is to much under the hood for my skills...
