Ouch Austin. But thanks Ricardo for explaining to Austin that I wasn't
actually contributing "code" and I also didn't use any reverse
engineering to come up with that discovery.

All I did was go to Microsoft's MSDN Libary web site and compare the
Toolbar messages listed there with the "publicly available" Microsoft
header files (you guys do actually allow yourselves to visit
Microsoft's MSDN Library every now and then and peruse Microsoft's
publicly available header files don't you?). And I discovered that
there were several Toolbar messages that were listed on the MSDN
Library web site that were not listed in the publicly available header

If you had actually gone to the web links I had listed before you
would have seen text similar to the following at the bottom of each

<< This message is not included in a public header at this time. It is
defined as WM_USER + 94. >>

All I was trying to do was give you guys actual, "published" names
from Microsoft for some constants you guys are using in your code so
you didn't have to suffer from looking at names like TB_UNKWN45E
rather than a much more meaningful and now published name of

I will list that information here again in case someone other than
yourself finds the information of use. But I really don't care whether
you make use of this discovery or not. I just figured since the code
from your community helped me out, I would try to give something back
to you guys. Take it and make use of it, or leave it. I really don't

TB_UNKWN460 is really TB_SETLISTGAP  (WM_USER + 96)
TB_UNKWN467 (which is not in the Wine source yet) is really

Take care, and good luck,

although he used disassembly to check our implementation, he gave msdn
proof for the notifications he talked about...
and didn't contribute code.
