Hi! I'm quite new in ASP. I want to define a variable when a link is 

pressed and use it in the following page. How can I do it? Using the "?" 

character in the link that I see in many web pages, how?

Actually, you don't have to define the variable.  You can build the URL of 

the following page like this:



http://WEB_PAGE_ADDRESS?varname1=value1



where "varname1" is the name of the variable, and "value1" is the value 

you want it to have.  Then, in the ASP code for that following page, you 

can use the Request.QueryString("varname1") to retrieve the value, like 

this:



<%

dim local1

local1 = Request.QueryString("varname1")

%>



You can have multiple variables, too.  Just separate the "varname=value" 

pairs with the ampersand character (&).

You don't need to use the Request.Querystring for this either, you could

do it like so

<%

Dim local1

local1 =3D Request("varname1")

%>



Also, say you are passing values generated in asp



<%

varname1 =3D 1

varname2 =3D 2

'generate link

link1 =3D "<a href=3D""page1.asp?varname1=3D" & varname1 & 

"&varname2=3D" &

varname2 & """>Link</a>"

response.write(link1)

%>

or within html

<%=3Dlink1%>

or (not recomended, the more you go between html and asp the slower the

page)

<a

href=3D"page1.asp?varname1=3D<%=3Dvarname1%>&varname2=3D<%=3Dvarname2%>">

Link</a>

That's true, you don't have to use the QueryString function.  If you just 

use Request("varname"), it will search variables in the URL *and* 

variables from the form.  However, if you know that the variable is being 

passed through the URL, it would execute slightly faster and probably be 

clearer to those that would have to maintain the code.
