It is very easy using nFlags variable. Here is the sample code:

BOOL CClickScrollingDlg::OnMouseWheel(UINT nFlags, short zDelta, CPoint pt)<br />
{<br />
	if(nFlags == MK_MBUTTON)<br />
	{<br />
		if(zDelta>0)<br />
			MessageBox(L"UP!!!");<br />
		else if(zDelta<0)<br />
			MessageBox(L"DOWN!!!");<br />
	}<br />
<br />
	return CDialog::OnMouseWheel(nFlags, zDelta, pt);<br />
}

Do you want to press middle button and scroll simultaneously? Am I right?
