How does one declare (DIM) variables which are available to the PAGE and not the Session? I can't see an event to put them into.
TIA,
---JC

You would declare them in the white areas between events. Keep in mind that each page is executed twice: 1st time when the page is shown, and 2nd time when the page is submitted. All variables except sessions will be lost when the page is executed each time, thus it's not possible to declare a variable that will work in all events.

Possibly -really- stupid reply: I thought one was not supposed to use those white areas, since I seem to recall them being overwritten as the page is changed.
Are they really -safe- to use? IOW: I won't lose my edits as the page changes?
THANKS!

White areas are empty and OK to modify. Only avoid modifying code in gray areas, except events.

Safe - yes. But I prefer to write custom code in separate files, then add
'include' statements to load my separate files. That way I KNOW they won't
get eaten (at least nothing more than my include would ever be lost). Plus
it's just easier (for me) to maintain.

Hello Don,
Can you be a bit more specific as to the procedure? I can see how to include files for JS or HTML styles, but how does one include a page for declaring page level variables? Do you put it in an Event? If so, which one?
THANKS!

JC,
What I do is place the includes for anything that is global in the first
line of the _events page.
So, for example, if I have a charts page, the first line of
charts_events.asp may have something along the lines of:
<!-- #INCLUDE FILE="FGWrapper.asp" -->
<%
Dim DataType, BaseDate, StartDate, EndDate, graph
'BindEvents Method @1-7F418D9D
Sub BindEvents()
In here you can see 2 things. First, the inclusion of an external class
file.
Second, you will notice that the very first line after the opening "<%" has
my global page variables defined.
These are used by multiple charts which are presentedon the same page, so I
only want to retrieve them one. In this case, they are CCGetParam's, in the
AfterPageInitialize event.
You could declare these anywhere in the whitespace area - I prefer to do
this at the very top for consistency.
Also, when you include a page, make sure it is not inside the <% - %>.
