File upload control size

Hi,

This code is for those people who are using ActiveX object and knows that browser will support the below script.

<script language=”javascript” type=”text/javascript”>

    var objFSO ;

    try

    {

        objFSO = new ActiveXObject(“Scripting.FileSystemObject”);

    }

    catch(err)

    {

        alert(err.message);

        alert(err.number);

    }

    function CheckExtention(el) // pass Upload File object’s ClientID here

    {

        var myel= document.getElementById(el);

        var file;

        var path = myel.value;

        //alert(path);

        file = objFSO.getFile(path);

        var size;

        size = file.size ; // This size will be in Bytes

  // We are converting it to KB as below

        alert(‘File Size is : ‘ + file.size /1024 +‘ KB’);

    }
