OnMouseWheel() vs OnVScroll()

[Jesper Knudsen]

I'm using mouse wheel as user input in a CWnd. But when vertical scroll bars are on, I'm receiving OnVScroll() messages instead of OnMouseWheel() messages. How can I ignore OnVScroll() messages, and always receive OnMouseWheel() as if the scrollers were not enabled? Thanks

Do you mean to say that, even if you are using mouse wheel for vertical scrolling, you are getting OnVScroll called ? It should not.

I might have interpreted your question wrongly, but OnVScroll(WM_VSCROLL) will be called only when you use cursor to drag scrollbar. In case on mouse wheel it will not be called. -- modified at 10:48 Monday 11th December, 2006

Well, I am infact not getting mouse wheel messages, only vscroll. That is, if the scroll bar is on. I think it depends on the mouse driver. Once I got two mice connected. One would send mouse wheel as expected, another would translate wheel messages to vscroll. So I need to break in, where the mouse wheel comes in to reject cscroll messages on mouse wheel.
