This is the code i am using for ajax call... the code is working fine with all the lower version browsers 5.5 , 6 and giving object doesnot support error only in Internet explorer 7.. why? any one help me?...

The code follows
// JScript source code
<script>
function getXMLObj()
{
if (window.XMLHttpRequest)
{ // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType)
{
http_request.overrideMimeType('text/xml');
return(http_request);// See note below about this line
}
}
else if (window.ActiveXObject)
{ // IE
try
{
http_request = new ActiveXObject("Msxml2.XMLHTTP");
return(http_request);
}
catch (e)
{
try
{
http_request = new ActiveXObject("Microsoft.XMLHTTP");
return(http_request);
}
catch (e)
{alert("Your Browser settings not suitable");
}
}

}
}

var XMLObj;
function getCons()
{
XMLObj=new getXMLObj();
url="test.aspx";
XMLObj.onreadystatechange=loadItems;
XMLObj.open('GET',url,true);
XMLObj.send(null);

}
function loadItems()
{
if (XMLObj.readyState==4)
{

var obj=document.getElementById("myDIV");
obj.innerHTML=XMLObj.responseText;

}

}
</script>

I am having similar problem, this link [blogs.msdn.com...] is relevent but seems to indicate your code is ok. Can you narrow problem to a particular line? My problem is getting responseXml, responseText is Ok and getResponseHeader("Content-Type") = text/xml and xml looks valid.

Because IE7 does support window.XMLHttpRequest, but does not support
.overrideMimeType, so you are returning null from the function.

overrideMimeType shouldn't come into play if it's not available, according to the script. Maybe your IE7 is having trouble getting the appropriate ActiveX object version? Here's what I use with no IE7 trouble:

var msxmlhttp = new Array(
'Msxml2.XMLHTTP.5.0',
'Msxml2.XMLHTTP.4.0',
'Msxml2.XMLHTTP.3.0',
'Msxml2.XMLHTTP',
'Microsoft.XMLHTTP');
for (i=0;i<msxmlhttp.length;i++) {
try {
thisConn = new ActiveXObject(msxmlhttp[i]);
} catch (e) {
thisConn = null;
}
}
if(!thisConn && typeof XMLHttpRequest!= "undefined") {
thisConn = new XMLHttpRequest();
}
if (!thisConn) {
thisConn = false;
}

Hope it's helpful.

function getXMLObj() {
if (window.XMLHttpRequest){ // Mozilla, Safari,... &&IE7!
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType){ //Not in IE7
http_request.overrideMimeType('text/xml');
return(http_request);// See note below about this line
}
}
else if (window.ActiveXObject){

The above code finds window.XMLHttpRequest for IE,
and so it does not run the else to get an ActiveX object.

But there is no return value for a browser that does support
XMLHttpRequest but does not support overrideMimeType,
as in IE7.
