Hi all - this is driving me crazy but I can't find a solution. I posted a while back that I had a file input in a form that I wanted to test the file to ensure it is not over a specified file size before submission so that the form data could be submitted and emailed.

I got everything working except on FF.

Now with plenty of head banging I managed to get it to work on all browsers and FF. Great; but it stopped working on IE. Brilliant! Why can't W3C enforce a single code base which everyone else just puts their eye candy on???

Any way - I've tried several solutions and I feel so close but so far - can any one help??

Code:
<div class="fileUploadEntry">
       <input type="file" id="attachment1" name="attachment[]" onchange="attachmentsGoodToGo.value = findSize(this, 5242880, 1)" />
 </div>

function findSize(fileInput, maxFileSize, id) {
	//limit is set to 5242880 (5mb) in bytes

        //simple detect IE version script
	var ver = getInternetExplorerVersion();
	if(ver > -1) 
	{
		//for IE
		var exceeded = false;
		var idNumber = id;
		alert("id = "+id);
		var elementID = "attachment"+idNumber;
		var oas = new ActiveXObject("Scripting.FileSystemObject"); 
//the above line no longer works because of IE security. 
//cannot find a jQuery solution to this
		var d = document.send.elementID.value;
		var e = oas.getFile(d);
		var f = e.size;
		
		alert("theFile = " + d);
		alert("theFile value = " + e);
		alert("fileSize = " + f);
		if(f > maxFileSize) 
		{
			var exceeded = true;
			//this file is greater than 5mb - warn the user
			alert("This file exceeds the 5Mb limit - please click Choose File and reselect or compress the file.");
		}
	}
	else {
		//for everyone else
		var exceeded = false, bytes;
		if(fileInput.files && ( bytes = fileInput.files[0].size) > maxFileSize) 
		{
			exceeded = true;
			alert("This file exceeds the 5Mb limit - please click Choose File and reselect or compress the file.");
		}
	}
	return exceeded ? 0 : 1;
}
Any pointers would be amazing!

cheers
