getting response string problem

[Mr. x]

Hello,

I have declared in my program (*.aspx) something like this :

<%@ Page Language="VB" Debug="true" %>
....

<%
dim current_view_pa ge
current_view_pa ge = "1"

if not (Request.QueryS tring is nothing) then
current_view_pa ge = Request.QuerySt ring
end if

%>
in the body section I put something like this :

....
<% if current_view_pa ge = "1" then
response.write( " .... ")
end if
%>
I got an error message :

Operator is not valid for type 'HttpValueColle ction' and string "1".

Why ?

Thanks :)

The QueryString object is a collection of name/value pairs, not an
actual string. Try something like this instead:

If current_view_pa ge.Item(<nameOf Param>) = "1" Then

Actually, the value of the name/value pair IS a string and should be
accessed as such:

<%
dim current_view_pa ge
current_view_pa ge = "1"

if Request.QuerySt ring <> "" then
current_view_pa ge = Request.QuerySt ring
end if
%>

By the way, you are using VB.NET now, not VB 6.0 and classic ASP so remember
to declare your variable types.

That point was never argued. What I said is that a NameValueCollec tion
is not a string. In the code posted, the user is attempting to see if a
NameValueCollec tion object is equal to "1". That's an invalid comparison
as well as an invalid assignment.

I was surprised to see he got away wth the assignment in the first place
until you pointed out the lack of type declarations.

I see what you are saying, but to clarify: Request.QuerySt ring does return
a string. It may be several name/value pairs strung together and, yes,
QueryString is a collection, but when accessed via Request.QuerySt ring, you
get a string value back. Because he did not specify a specific name (or
index) to retrieve just means he'll get the whole string back and that is
his problem. As you pointed out, he's trying to evaluate the whole string
(names & values) against one particular value for one particular key in the
collection.

My main point was that he was using "Not Is Nothing" when he should have
been using <> "".

He is assigning the whole QueryString to "current_view_p age" and then later
checking "current_view_p age" for a value of "1", rather than either
assigning "current_view_p age" just the value of one of the keys in the
QueryString (which hopefully contains a value of "1") or when he's checking
the value of "current_view_p age", he should see if it contains "1" rather
than if it = "1".

Sorry for any confusion.

until you pointed out the lack of type declarations.
