<html>

<body>

<form action="addition_n.asp" method="post">
-
First number: <input type="text" name="no1" size="20" />

dim n1,n2,n3
-
n1=cint(Request.form("no1"))

n2=cint(Request.form("no2"))

Sorry I can't display it VB.NET but in C# it's done this way - protected void Button1_Click(object sender, EventArgs e)
-
{
-
int i = 0;
-
i = Convert.ToInt32(TextBox1.Text) + Convert.ToInt32(TextBox2.Text);
-
TextBox3.Text = i.ToString();
-
}

The big problem is that the ASP is executed on the server before it is sent to the browser, but your call is executed when the user clicks the button. The server will never execute the function, because IT ALREADY FINISHED EXECUTING ALL OF THE ASP CODE. If you want it done on the browser, you will need to use a client-side technology, like javascript. Otherwise, try it like this: - <form method="post" action="thisPage.asp">
-
<input type="text" name="n1" value="<%=request.form("n1")%>">
-
<input type="text" name="n2" value="<%=request.form("n2")%>">
-
<%
-
dim n3
-
n3 = 0
-
if request.form("n1") <> "" AND request.form("n2") <> "" then
-
n3 = cint(request.form("n1") + request.form("n2")
-
end if
-
<input type="text" name="n3" value="<%=n3%>">
-
<input type="submit" name="submit" value="Add">
-
</form>
this method submits the form back to the server, the server looks it over and refills the form with the original inputs, and performs the addition, before sending the form back to the client. Does this make sense?

I've been playing with this form validation method for a while and have
tried an array of things but haven't had any luck with a couple items.
1. The validateForm() function doesn't detect when the Min price is
greater than the maximum price.
2. The validateForm() function doesn't call isNumber() on the minBaths,
maxBaths, minBeds, or maxBeds.
3. Despite errors in input and the validateForm() function returning
false, the form is still...

I don't do a lot of coding in Access & so every time I come back to do

If I had 2 tables, one that displayed ClaimNo, PartNo, and Quantity, and

add the associated quantity to table 2 from table 1, and if it is not found
to add it, with its associated quantity to table 2.
This should be simple.....its just a running total/tally....

I just realized that the code I inherited is using all asp.net server

It seems to me that as I begin to write the client side javacript code for

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
