You're getting WM_HSCROLL messages with different scroll codes (wParam's). You're probably receiving SB_THUMBPOSITION, SB_THUMBTRACK and SB_ENDSCROLL.
From VC++ online help:
SB_BOTTOM
Scrolls to the lower right.
SB_ENDSCROLL
Ends scroll.
SB_LINELEFT
Scrolls left by one unit.
SB_LINERIGHT
Scrolls right by one unit.
SB_PAGELEFT
Scrolls left by the width of the window.
SB_PAGERIGHT
Scrolls right by the width of the window.
SB_THUMBPOSITION
Scrolls to the absolute position. The current position is specified by the nPos parameter.
SB_THUMBTRACK
Drags scroll box to the specified position. The current position is specified by the nPos parameter.
SB_TOP
Scrolls to the upper left.
