Hi Chris,
As for the validating form inputs and submit it question you mentioned,
here are some of my understanding and suggestions:
1. For HTML page in webbrowser, when there is some entry fields and submit
buttons, if we set focus on a certain entry field( for example input some
value in a textbox) and hit enter key, we will found the page be submited
as if one fo the submit button is clicked. At lease IE browser will behave
as this. In fact, this is because when the entry field is accepting input,
the focus of the page is on the first submit button on the form, you can
have a check on this, so when we hit enter key, the focused submit button
is clicked. Also, this is not always true when the page's structure become
very complex. And I know many guys will manually use some script to hook
the entry fields's key down event and use script to submit the form in that
event.
2. For validation the form's fields and submit it to the correct page, my
suggestion is we just submit the form to the same page self. Then in the
page's code block, we do the validation, when the input data are valid, we
use server.transfer to redirect the request to our target processing page(
the forms collection will reserve when using server.Transfer to skip from
different page). For example:
<%
dim method
method = Request.ServerVariables("REQUEST_METHOD")
if method = "POST" Then
' do the validation here
if Request.Form("username") = Request.Form("password") Then
Server.Transfer("result.asp")
else
Response.Write("Invalid input!")
end if
end if
%>
also, make sure your form's Method is set to "POST" like:
<form name="xform" action="" method="POST">
Hope helps. Thanks,

| I've just realised part/all of the problem... My application uses a
| client-side script to validate the form inputs, before setting the Action
| property of the form and submitting it. Therefore, if the button is not
| pressed, the validation code is not run and the Action property is not -
so
| the page POSTs back to itself.
|
| Therefore I need to be able to detect that the Enter key has been
pressed,
| in which case I can validate the code and submit the form accordingly.
Can
| anyone give me any pointers on the best way to do this?
