Minor correction: that's under the assumption that the thread
that registered the window class (with RegisterClass()) is the
same thread creating the window, which is the case most of the
time.
But if it's one process instantiating the window of a different
process (which happens sometimes), or if it's one thread
instantiating the window of a different thread (which happens
more rarely), that's obviously not the case...
Never mind, I actually messed up the last part; it's the same
thread throughout:

I just got this confused because if you happen to use
SendMessage() to send the message, THEN the rule I mentioned
applies.
But here, the system calls the window procedure directly, and as
the link says, only the current ever calls the window procedure.
