Web Development

1. the user is not able to select options with the keyboard
2. when the user uses the mouse wheel and the select has focus the form is again submitted by accident
3. the form will not be submitted if the user has JS disabled

<script type="text/javascript">
function doSubmit(frm) {
    frm.submit();
}
</script>
...
<select onchange="doSubmit(this.form)">

Ahh this old chestnut. I'm going to take a stab in the dark here and say that you've got a Response.Redirect in the Login.asp file. This is getting called after you've written some data out to the client. There is a simple fix for this, just add

Response.Buffer = true

Setting Response.Buffer to true, tells asp to buffer all of the output until the page has been fully parsed and is ready to go. This means that if you make a change to the HTTP headers mid-page (Response.Redirect sends HTTP headers telling the browser that the requested item has been moved somewhere else [in this case wherever you Response.Redirected to]), asp will just issue out the final headers. Without buffered output, asp will have already sent an HTTP header saying that the resource was found as is following, then it will try to tell the browser that it moved (hence the error)

You will probably find that this page would work "as is" in IIS 5.0 as buffering is turned on by default, whereas in IIS 4.0 it was turned off.

If I'm wrong and this doesn't fix things for you, then please provide the broken code and I will try to help you further.

Accept: application/cab

CString szHeaders = "Accept: application/cab\r\n";
pFile->AddRequestHeaders(szHeaders);
