Soooo many handles to remember to free in the right order, even before you got into OLE/COM. It was a lot of fun to come up with your own C++ wrappers to put them under RAII -- and this was before "smart pointers." You sort of had to iterate on a few versions of that, trying out mechanisms to scope sharing, to understand why MFC was the way it was.

Fond memories of the #winprog IRC channel. Discussions there, theForger's tutorial, and Charles Petzold's books got me going on Startup Control Panel and the like.

Oh man, I remember fighting with handle leaks back then too - that stuff was a rite of passage.

I remember that on Win 9x, once you leaked too many handles, bitmaps and icons would just become black boxes.

This is still true; there are maximum limits on the number of open handles in a process.
