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
serge

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.

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.

Re: Redefined variable

Why do you need to load it twice?

Re: Redefined variable

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.

Re: Redefined variable

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="menuba r.asp"-->

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

Learn to use subs and functions.
