set s=CreateObject("Adodb.Stream")
S.Mode=3
S.Type=1
S.Open
s.LoadFromFile(server.mappath(f))
response.contentType="application/x-gzip"
response.addheader "Content-Disposition:","attachment; filename=" & n
response.binarywrite(s.Read(s.size))

<body oncontextmenu="return false">
或
<s cript language="Javas cript">
<!--

if (window.Event)
document.captureEvents(Event.MOUSEUP);

function nocontextmenu()
{
event.cancelBubble = true
event.returnvalue = false;

return false;
}

function norightclick(e)
{
if (window.Event)
{
if (e.which == 2 || e.which == 3)
return false;
}
else
if (event.button == 2 || event.button == 3)
{
event.cancelBubble = true
event.returnvalue = false;
return false;
}

}

document.oncontextmenu = nocontextmenu; // for IE5+

禁止鼠标右键的动作

　　＜Script Language = "javascript"＞
　　function click() { if (event.button==2||event.button==3)
　　{
　　alert(’禁止鼠标右键’);
　　}
　　document.onmousedown=click // --＞
　　＜/Script＞

或：<script language="javascript">
function click() { if (event.button==2)
{alert(’*^_^*’); } } document.onmousedown=click // -->
</script>
