What is the notification code that gets sent when a scrollbar event occurs?

[skyapie]

Hi, I'm using the OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult) method to find out when a user uses a scrollbar. Except I'm not sure what to be checking lParam against. I've casted lParam to be a NMHDR*, but when I check the value of pNMHDR->code, it's usually 0xFFFFFFF4. Can anyone tell me what xxxxx should be in the following line? BOOL CBaseFormView::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult) { NMHDR* pNMHDR = (NMHDR*)lParam; **if(pNMHDR->code == xxxxx)** { //Do stuff } } Or can someone tell me if I'm going about this the wrong way? Thanks, skyapie

You will get control at OnVScroll() OnHScroll() when the suer scrolls the scrol bar Rinu Raj

If this scrollbar is of this view only then it will not send WM_NOTIFY message. Handle WM_VSCROLL message

This code will work , if you want to handle scrolling of child window of this view, lets say scrolling in listcontrol present as child of this view.

Prasad Notifier using ATL | Operator new[],delete[][^]

That will work if the scrollbar is for the view, not for a list control or list box in the view...
