Redefined variable

[Serge Myrand]

Hi everybody,

In an ASP page, I need to load twice an include file that contains
variables. So I get an error message "variable redefine" I tried to test

with VarType before to define the variable (dim) with no success. Is it
faisable with VBScript to define a variable (dim) under condition.

' this code gives an error
if VarType("MyVar") = vbNull then
dim MyVar
end if


many thank's

Why would you need to include a file twice? If it has different
values for the variables, name them differently and include them once.

No.

' this code gives an error
if VarType("MyVar") = vbNull then
dim MyVar
end if

Hmm... Using a variable before defining it, why would that cause an
error?

You can REDIM if needed, but rethink your code and do it correctly the
first time.

One way, would be to lose 'option explicit' and all your variable
declarations (dim statements)

Although I have to say, including a file more than once is generally a sign
of bad coding practice....

I'm sure there will be a much much better way of achieving what you want
without resorting to including the same file multiple times.

Hi,

Because this is a menu bar and there is an option taht allow the user to put
it at the bottom and at the top of the page.

OK. So why don't you put it in a function and call the function to output
the menu?

Function TheMenu
TheMenu = "Some HTML for the menu"
End Function

If MenuPreference ="top" Then
Response.Write TheMenu
End If

So? Do this:

[Menubar.asp]

<%
Sub Menubar
Dim Menubar1, Menubar2
...Menubar code...
End Sub
%>

[Page.asp]

<!--#include virtual="menubar.asp"-->

<%
Menubar
Response.Write "Page text and stuff..."
Menubar
%>

Learn to use subs and functions.
