LRESULT
CContentWnd::OnCreate(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
::CreateWindowEx(
0,
_T("ScrollBar"), NULL,
SBS_HORZ,
0, 0, 0, 0,
m_hWnd,
NULL, NULL, NULL );

SCROLLINFO si;
RECT rcClient;

GetClientRect( &rcClient );

si.cbSize = sizeof( SCROLLINFO );
si.fMask = SIF_ALL;
si.nMin = 0;
si.nMax = nXMax;
si.nPage = rcClient.right - rcClient.left;
si.nPos = nXTop;
si.nTrackPos = 0;

SetScrollInfo( SB_HORZ, &si );

return 0;
}
