Conditional Includes

Thomas · Jan 16, 2004

Hi,

Will this work in asp 3.0:

If True Then

Else

End If

- Thomas

Kris Eiben · Jan 16, 2004

Yes, it will work, assuming you start and end your ASP blocks
correctly -- though probably not in the way you expect. Both files will
be included, but only the one that matches the condition will be used.

Curt_C [MVP] · Jan 16, 2004

your IF is weird but the premise is correct

TomB · Jan 16, 2004

Yes and no.
The include files are processed first, so the contents of test1.asp and
test2.asp will be plugged in. Then your if/then will be processed.

Probably a better solution would be to wrap the contents of test1.asp in a
subroutine, and test2.asp in a separate subroutine.

Example.

test1.asp

Sub test1sub()
'code from test1.asp
End Sub

test2.asp

Sub test2sub()
'code from test2.asp
End Sub

page.asp



If True then
Call test1sub
else
Call test2sub

So

if test1.asp contains this line:
response.write "Hello 1"

and if test2.asp contains this line:
response.write "Hello 2"

The result of

will allways be

Hello 1
Hello 2

No. The processor would convert it to
If True Then
response.write "Hello 1"
Else
response.write "Hello 2"
end if

which would result in
Hello 1

So, it basically does what you want (presumably) but you can run into
conflicts.
If test1.asp contains
Dim x
x=1
and test2.asp contains
Dim x
x=2
then you've "redimmed" and will get an error. However, if they are in
subroutines, the scope of x is within the subroutine so you won't have a
conflict.

Alex Goodey · Jan 16, 2004

No the reult will alwasy be

Hello 1

doing

If True Then

Else

End If

If True Then
response.write "Hello 1"
Else
response.write "Hello 2"
End If

is exactly the same as doing

in my routines this runs well like:
<%
if Session("logado") <> "sim" then
'Rotina de verificação de sessão do usuário só funciona dentro das
tags<body></body>
%>

<%End If%>
bye

What most of the responses want to emphasise is that, even though the logic will work and only the 'correct' page will
be displayed, all of the includes will be read and processed before anything else happens...If those pages are large
and/or contain lots of processor intensive or memory heavy stuff, you can run into real resource depletion problems.

The faq citation from Tom B :
http://www.aspfaq.com/show.asp?id=2042

has, at the end, a discussion of using Server.Execute - It will help, if it can be employed in your situation.

If the content in test1.asp and test2.asp are not dependent on the
rest of the page ... I would consider Server.Execute in your if/then
... that way the entire pages code from the files won't be pulled in
... only what is executed.
