Hi Cédric Moonen, Basically my class is subclass of CStatic. I set scrollinfo using below code

void CImageViewer::PreSubclassWindow()
{
CRect rect;
GetClientRect( &rect );

// set horizontal scroll bar
SCROLLINFO si;
ZeroMemory( &si, sizeof( SCROLLINFO ));
si.cbSize = sizeof( SCROLLINFO );
si.fMask = SIF\_ALL;
si.nMin = 0;
si.nMax = nScrWidth;
si.nPage = rect.Width();
si.nPos = 0;
si.nTrackPos = 0;
SetScrollInfo( SB\_HORZ, &si );
CStatic::PreSubclassWindow();

}

and handled OnHScroll Message

void CImageViewer::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
SCROLLINFO si;
int nScrollPos = nPos;
pScrollBar->GetScrollInfo( &si );
int nCurPos = si.nPos;
int nMin = si.nMin;
int nMax = si.nMax;

switch( nSBCode )
{
	case SB\_THUMBPOSITION:
	case SB\_THUMBTRACK:
		nScrollPos = si.nTrackPos;
		break;
	case SB\_LEFT:
		nScrollPos = nMin;
		break;
	case SB\_RIGHT:
		nScrollPos = nMax;
		break;
	case SB\_LINELEFT:
		nScrollPos = nCurPos - 2;
		break;
	case SB\_LINERIGHT:
		nScrollPos = nCurPos + 2;
		break;
	case SB\_PAGELEFT:
		nScrollPos = nCurPos - 5;
		break;
	case SB\_PAGERIGHT:
		nScrollPos = nCurPos + 5;
		break;
	case SB\_ENDSCROLL:
		nScrollPos = nCurPos;
		break;
}

if(nScrollPos < nMin) nScrollPos = nMin;
else if(nScrollPos > nMax) nScrollPos = nMax;
pScrollBar->SetScrollPos( nScrollPos );
Invalidate();
CStatic::OnHScroll(nSBCode, nPos, pScrollBar);

}

After this a scroll bar appears with my control. But i can't change scroll position.
