Hi Alexander

Yes, we found that and it's helpful, to a point. However (a) we're building
a wrapper, not an app and (b) it uses an old version of ATL and won't build
on VS7.

As a wrapper, we don't have access to the event loop. The keyboard solution
in this app to intercept keystrokes in the PreTranslateAccelerator of one
window and WM_FORWARDMSG them to another window. So far, we haven't managed
to find a way to do that in a wrapper. Surely getting the keyboard to work
can't be that hard?

Getting it to build in VS7 may be just a few tweaks -- dunno yet. There are
heaps of "ambiguous base class" errors.

The ideal would be just a few hints about what to add to the simple
container solution provided in the help and on MSDN, to get the keyboard to
work and to enable ambient properties. Doesn't anybody actually use this
sample? Everybody must run across the same problems.
