Dennis Schram #1 / 4	VScroll-problem Hi, VB-Lovers, how can I check if the upper button or the lower button of a vscroll control is pressed? Thanks in advance, Dennis Schramm www.dennis-schramm.com

Hugh Laderma #2 / 4	VScroll-problem One method is to subclass the form for a WM_VSCROLL (&H115) message. I believe lParam is the hWnd of the control, wParam = 0 indicates the top arrow; wParam = 1 indicates lower arrow ... although I've been know to be wrong in the past.
