              if(top.document.body.offsetWidth==screen.availWidth)
               var ismax=true;
    if (!ismax)
  { ismax=true;
  
    w=window.open("login.aspx","_blank","status=no,menubar=no,titlebar=no,toolbar=no");
w.moveTo(0,0);
w.resizeTo(screen.width,screen.height);
w.document.getElementById("set1").value="Restore";
    window.opener=null;
self.close();
alert(ismax);
}
else
   {
    ismax=false;
    w=window.open("login.aspx","_blank");
w.moveTo(0,0);
w.resizeTo(screen.width/2,screen.height/2);
w.document.getElementById("set1").value="Maximize";
