Create sub-window in IE to transmit value and receive value "window.showModalDialog"

Parent window creates a window

var backinfo = window.showmodaldialog (' userselect.aspx ', ' ', ' dialogheight=600px; dialogwidth= 600px; edge=Raised; Center=yes;resizable= No; status= No;help=no ');

The child window calls JS to close itself and return the value

function Selectcompany (obj) {

Window.returnvalue = obj;
Window.opener = null;
Window.close ();
}

The Var backinfo defined by the parent window will receive the child window Window.returnvalue;
