XMLHttpRequest cannot be resolved to a type

[onion923]

function createXMLHttpRequest()
{
if(window.ActiveXObject)
{
try
{
return new ActiveXObject("MSxml2.XMLHTTP"); }catch(e)
{
return new ActiveXObject("Microsoft.XMLHTTP");
}
}
else if(window.XMLHttpRequest)
{
return new XMLHttpRequest();
}
}

ActiveXObject 和 XMLHttpRequest 不能解析 为什么？
