AJAX problem on IE7

[agun]

Hello,

I'm having problem implementing AJAX on IE7. In other browser it works totally fine. In IE7, if i enable the Enable Native XMLHTTP support, everything just went wrong.

Here is the XMLHTTP request code : (thanks to www.masykur.web.id)

----------------

 http_request = false ;
        if (window.XMLHttpRequest) { 
            http_request = new XMLHttpRequest();
            if (http_request.overrideMimeType) {
                http_request.overrideMimeType('text/xml');
 
            }
        } else if (window.ActiveXObject) { // IE
            var aVersions = [ "MSXML2.XMLHttp.6.0", "MSXML2.XMLHttp.5.0", "MSXML2.XMLHttp.4.0", "MSXML2.XMLHttp.3.0", "Microsoft.XMLHTTP" ];
            for (var i = 0; i < aVersions.length; i++) {
                try { http_request = new ActiveXObject(aVersions[i]);
                    break;
                }
                catch (e)
                {
                // Do nothing 
                } 
            }
        }

------------

But if i disable the Enable Native XMLHTTP support, it just run smoothly.
I've read from several forums that this problem is quite common, but i just can't find out the work-around.


How do i overcome this problem?
Since out there i can't tell the IE7 user to 'disable their XMLHTTP native'.
Btw, i guess in IE6 there's no problem at all.

Thanks...

some ways I would try to solve this:
- try-catch on both objects
- try the ActiveXObject first

this one is working fine for me:

    try {
        request = new XMLHttpRequest();
    }
    catch (e){
        try {
            request = new ActiveXObject("Msxml2.XMLHTTP"); // IE 5
        } catch (e) {
            try {
                request = new ActiveXObject("Microsoft.XMLHTTP"); // IE 6
            } catch (e) {
                alert("...your error message here...");
                return false;
            }
        }
    }

must proceed, will check later
