Detecting scrollbar click on CScrollView scrollbar

I have a CScrollView derived view in an MFC application, and I want to
detect when the user clicks on the right scrolling button of the
scrollbar (not the mouse). I need to do this so that I want to
increase the scroll size if the user wishes to go beyond the current
scrolling range.

How can I do this?

Thanks in advance for your help,
Abhijit

Add a message handler to your view for WM_HSCROLL. Your message handler
must call CScrollView::OnHScroll if you want it to continue working
normally.
