> Sorry, I can't help you for that matter. I have looked carefully in my system, the structure is different with LOGFONT structure.
I know the fontsize is the first char with an old trick :-) you know change the appearance one at a time, then refresh the regedit, you will find out what the data is ( faster than searching in MSDN :-) )

Ok, that's what I'm going to do because I didn't found anything neither in MSDN nor over the internet. But (as always) leak of information may raise incompatibility problems on some systems where "unused" bits are used in unknown way.
