form feild hints are not displaying for textboxses inside create user wizard?



I'm using following JS code to display input hint box besides the textbox whenever that asp.net textbox receives focus. 

I'm doing this for a registration form and all of the textboxes are inside the asp.net create user wizard control.

<script type="text/javascript">
function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {

function prepareInputsForHints() {
	var inputs = document.getElementsByTagName("TextBox");
	for (var i=0; i<inputs.length; i++){
		// test to see if the hint span exists first
		if (inputs[i].parentNode.getElementsByTagName("span")[0]) {
			// the span exists!  on focus, show the hint
			inputs[i].onfocus = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "inline";
			// when the cursor moves away from the field, hide the hint
			inputs[i].onblur = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "none";

"Type ASP.x is not defined" error for dynamic user control when publishing updateable


I have a user control (ContainerCtrl) which programmatically instantiates another user control (SimpleCtrl) in OnLoad. It builds and runs fine, but when I publish it I get the error "error BC30002: Type 'ASP.SimpleCtrl' is not defined." (If I publish without the "updateable" option there's no error, but I need the site to be updateable.)

I assume this has to do with the particulars of how the assembly(ies) are built for the different compiler options. My question is, how can I get it to work properly for "updateable" publishing?

VS 2008 / .NET 3.5 sp1

The code follows (web.config is the default from Visual Studio).

Many thanks, Dave


<%@ Control Language="VB" ClassName="SimpleCtrl" CodeFile="SimpleCtrl.ascx.vb" Inherits="_SimpleCtrl" %>

Typically, examples illustrating Office programmability use Visual Basic or Visual Basic .NET. In this article, the author develops a Smart Document for Excel using C++. He describes the new ISmartDocument interface and shows how to use it to manage a simple task list such as an Excel spreadsheet.

implementing a search similar to what you have in google when you type in a word


Dear all;

I have a textbox and what I would like to implement is basically a situation similar to what you have in google when you type in a word. In otherwords,

in the textbox when you type in J, it should generate a list of names that starts with O in alphabetical order, then next when you type in o, so that now you have Jo, it should generate a list of names instead that now starts with Jo in alphabetical order, then again when you type in h, it should generate a list of names that starts with Joh and so on. A sample code could be helpful. Thank you. No Javascript of Jquery please. All help will be greatly appreciated.
