Since I got such great response from the first set of questions,
I'll try my luck with round number two:

How does one cause a static window to respond to input?  I have a
fairly complex arrangement of static windows that I want to be able
to click on and get a response from...  Straight subclassing doesn't
work.  The subclass procedure never even gets called for the mouse
events.

(Somewhere in the Petzold book, he says that statics trap the
NCHITTEST message to disable mouse events.  Where and how do I
re-enable them?)

(Email, please, our news server just bit the dust)

A quick way is to create each static control using CreateWindowEx
which by default means your window DOESN'T have the
WS_EX_NOPARENTNOTIFY style.
Your dialog box therefore will receive WM_PARENTNOTIFY messages
and you can process these to tell you which control is pressed
in (only those created this way and added to the dialog box
will generate the message). It will even tell you the (x,y)
position 8-)
