Thanks for the tip. I was using ILDASM which was quite a bit slower than what I was able to do with Reflector. It was pretty easy to find the code in the VS assemblies that called the serializers. Turns out it only calls Serialize on objects of type CodeDomSerializer. Now if only I can figure out what all of the serivces that DocumentDesigner creates do (the inheritance ones, InheritanceUI and IInheritanceService, have got me befuddled, an idea?).

A specific use of such an integer is a pointer. There isn't anything special about a pointer, except that its value refers to a location in memory.

I tried something else out that gave me strange results as well... Instead of using PostMessage, I switched to using SendMessage. The WM_NCPAINT message is now reaching WndProc, however, the strange thing is that the drawing that I do there does not show up. The drawing code works fine in response to WM_NCPAINT messages caused by resizes, min/maxes, etc... Any ideas?

I'm fighting with the very same thing, if you find a solution, please let me know. Sorry didn't helped you out :) Andres Manggini. Buenos Aires - Argentina.
