here is my problem ... i would like to populate the value of a textbox based on a form in a popup window. i keep getting an "object expected" error. i think the problem is that the popup window is a .net page that is submitted. by that i mean there is a search function on the popup ... i tested setting the textbox without doing a search and that worked fine ... it's only when i preform a search and then try to set the value that i get the error.
thanks - brian

okay - here is the code in the main page (the one i want to set the value):
function pop()
{
var newWin;
newWin = window.open("code.aspx","airportcodes",'resizable=no,scrollbars=no,width=200,height=250,toolbar=no')
}

<form id="form1" runat="server">
<div>
<table>
<tr><td><asp:Label ID="lblErr" runat="server" Text=""></asp:Label></td></tr>

<tr>
<td>From City or <a href="javascript:pop();"> Airport Code</a></td>
<td><asp:Label ID="lblDepDate" runat="server" Text="Departure Date"></asp:Label></td>
</tr>
</table>
</form>


here is the code the in the popup:
<script>
function setCode()
{
window.opener.document.all.form1.txtDepCity.value="jjj";
window.close();
}
</script>

<script runat="server">
sub search(Source As Object, e As EventArgs)
lblCodes.Text = "<br><a href=javascript:setcode();>" & txtCode.text & "</a>"
end sub
</script>

<html xmlns=" >
<head runat="server">
<title>airport code search</title>
</head>
<body>
<form id="form2" runat="server">
<div>
<asp:TextBox ID="txtCode" runat="server"></asp:TextBox><asp:LinkButton ID="LinkButton1"
runat="server" OnClick="search">search</asp:LinkButton><br />
<asp:Label ID="lblCodes" runat="server" Text=""></asp:Label>&nbsp;<br />
</div>
</form>
</body>
</html>

1) you don't have any fields in your main page with the name "txtDepCity". in fact, your fields don't have names at all. give the field the correct name, or use the getElementById method.

2) do not use the "all" collection - it is specific to IE only.

3) call your function in this manner:
Code: 
<a href="#" onclick="setcode(); return false;">

sorry - was only trying to post relative code, here is my form from the main page:

<form id="form1" runat="server">
<div>
<table>
<tr><td><asp:Label ID="lblErr" runat="server" Text=""></asp:Label></td></tr>

<tr>
<td>From City or <a href="javascript:pop();"> Airport Code</a></td>
<td><asp:Label ID="lblDepDate" runat="server" Text="Departure Date"></asp:Label></td>
</tr>

<tr>
<td><asp:TextBox ID="txtDepCity" runat="server"></asp:TextBox></td>
<td><asp:TextBox ID="txtDepDate" runat="server"></asp:TextBox></td>
<td><a href="javascript:show_calendar('document.all.form1.txtDepDate', document.all.form1.txtDepDate.value);"><img src="cal.gif" width="16" height="16" border="0" alt="Click Here to Pick up the timestamp"></a></td>
</tr>
</table>
</form>

use the getElementById method:

Code: 
<script [blue]type="text/javascript"[/blue]>
function setCode()
{[blue]
  var d = window.opener.document;
  d.getElementById('txtDepCity').value = 'jjj';[/blue]
  window.close();
}
</script>

there are multiple lines of javascript. please provide an error message and error line, or a link to your site.

per my first post, the error message is "object expected" line 0. according to the ms script debugger.

it would be much more helpful if you posted the code that the browser generates, rather than your ASP code. it is hard to tell where line 0 is - that most likely means inline javascript rather than a function. it could also very well be somewhere that you haven't even posted.

and if your error is happening on your call to the search sub, then you're in the wrong forum - that's VBScript.

it's not happening there ... the label is being changed fine and dandy. like i said, if i change the code to call the setCode() function instead on search(), it works fine. it has something to do with calling the search subroutine first: here is the generated code:

<script>
function setCode()
{
var d = window.opener.document;
d.getElementById('txtDepCity').value = 'jjj';
window.close();
}
</script>



<html xmlns=" >
<head><title>
airport code search
</title></head>
<body>
<form method="post" action="code.aspx" id="form2">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTE2NzIyMzE2NA9kFgICBA9kFgICBA8PFgIeBFRleHQFKTxicj48YSBocmVmPWphdmFzY3JpcHQ6c2V0Y29kZSgpOz5mZXc8L2E+ZGRk4DB3+4WYYrwAA+5O+62Owm+KERI=" />
</div>

<script type="text/javascript">
<!--
var theForm = document.forms['form2'];
if (!theForm) {
theForm = document.form2;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit();
}
}
// -->
</script>


<div>
<input name="txtCode" type="text" value="few" id="txtCode" /><a id="LinkButton1" href="javascript:__doPostBack('LinkButton1','')">search</a><br />
<span id="lblCodes"><br><a href=javascript:setcode();>few</a></span>&nbsp;<br />
</div>
</form>
</body>
</html>

in the code you have there, you are calling setcode(), yet the function is described as setCode(). case sensitivity matters. try that and let me know...
