Application Variables Vs Include File
What are the best methods for using global constants and variables? I've noticed that many people put all global constants in a file and include that file on every page. This is the best way of doing it - is it not? Once the application has loaded the page it is cached and is immediately available for other pages.
With global variables - the best thing to do would be to use application variables - so long as there weren't too many declared. Is there another (easy) way of using global variables apart from using application variables?

i have response.contenttype= "application/msword", i follow that with <!--#include virtual="/slof.rtf" --> and it doesnt work, the other version of this file has a string as long as any i have seen, don't know why, this was working until we moved it off an unstable server. when i navigate in my software it shows the text of the asp file rather than executing the instructions.
basic history, it's a report viewing system (old) that uses vb6 and asp2.0 to generate reports that were written in word, do i need to convert the report to html and then add that to the bottom of my asp file.

I am using IIS 6.0 and am trying to use application variables to track uasge. They work fine as long as there is an active client but about 20 minutes after the last activity they are reset to the default values declared in the global.asa file.

If I'd use 1000+ application variables, would it decrease my server's performance?

I'm building a web app with a lot of ASP files which I'd like to split out into several different subfolders. However, I noticed that application variables that I set up in my Application_OnStart event sometimes survive switching to a different folder while at other times they do not. I am relatively new to ASP so I'm not sure if I'm doing something that inadvertently unassigns these variables.
One thing I kow I'm not doing is explicitly reassigning or unassigning them.My other option is to assign them in a default.asp or some other generic file that I replicate in all my folders and include in the entry point asp file to each folder,but I'd rather avoid the redundancy so as not to complicate maintenance further.

can I put together an object (not too big, just a small array or something) and chuck it in an Application variable or are there better ways to do this? Sessions are okay if it's a better alternative to Application but I'd rather skip cookies if I can.

I would like to know what are the Advantages &
Disadvantages of using Application variables in an ASP page.
In my application I would like to store some physical
paths from database to application variables.
I'm in a dilemma whether to hold this values in
application variables or in server side variables in
an include file. Please help me with this..

users login and can navigate an administration area, however, at random (it seems) when you click on a link to navigate to another spot in the admin portion the application variable used to denote the user as an admin is getting changed, and therefore load the homepage because it thinks you are not logged in. any suggestions? need more info?

I've got two domain names sharing the same IP address that use ASP VBScript
If I set a session variable with domain 1, it is only available for domain 1 - this is
correct?
If I set an application variable with domain 1, the app variable is sharing across all
domains using that IP address - this is correct?
This is the behavior I am seeing and I want to make sure that my server is set up
correct. I especially want to make sure application variable behavior is correct.

Has anyone worked with Application variables in an array format? I need to create a list of 40 items using some sort of persistant array. I can do this with a DB, but in this case, it would not be efficient.
I did a few tests by trying to pass an array to an Application var, but can't seem to get it back.
<% Dim MyArray(39)
'populate the array
Application("myArray") = myArray
%>
then on another page, I tried
<%
Dim myArray(39)
myArray = Application("myArray")
'loop through the retrieved elements
%>
This doesn't seem to work.. anyone did something similar with good results?

i would need to know if i can permanently modify the content of the global.asa file.
I am writing a web log in form that enables users to change their password (i dont need much security, this is more for practical purpose so i use application variables), these passwords are defined in the Application_OnStart() event but i would like to be able to change them without having to manually rewrite them.

I want to store the link of the page that each user of my web site visited so it can help me to personalise information for each user depending on the pages visited.I don''t know what kind of variable should I use.
If I understand well, a Session variable is deleted when the session end so when a user close the browser and then reconnect to my web site, the session variables used the first time will be deleted and I can''t keep track of the pages visited.Same thing for the application variable except that the variables will be deleted when the application stops.

I intend to use application variables to control access to editable blocks on an intranet site. There are about 300 blocks currently and that may grow to as many as 400 as time goes along.
Using the scheme I am thinking of an application variable will contain the username of the person currently editing a block. Is there a way to "destroy" the application variable so it no longer occupies memory or is this anything to be concerned about? I don't plan to place much more than a 20 character string into the variable.

I have absolutely no idea how global.asa works. I've read through quite a number of articles and they're all fine and dandy but implementing it on my (first) ASP application just doesn't work. It's amazing how ASP.NET automates everything for you.
Anyway, I need to store session variables and I have no idea how to. I have no global.asa file, but I can declare session variables fine. So does that mean that somewhere in the ASP process, a Session_OnStart() method's already running.
If I create a global.asa file, I put it in the same directory with other ASP files right?
A global.asa file should contain the basic four application/session methods... and shouldn't really contain much code, unless I want to start a variable with a default value. True or false (I say true). Code:

i have many different variables like addr, addr1, addr2 addr3 etc and i want this to occur
if addr = "" then
error = "ERROR:You have not entered all the required information. <br>Press the Back Button on your web browser and try again."
Response.Write error
But that only works for addr. Is there any way to include addr2 and the rest of the variables in that statement without writing it out 50 times

Is there a way i can send variables to an included page other than the session. I know about doing it via the session but i find that a bit messy and it might affect system performance.
can i use
server.execute (my.asp?id=6)
or something similar ?
I have to include a menu on the side of every page that looks different depending on what page is being displayed so i need to find a way to do this properly.

I'm just dipping my toes into server-side scripting.
The Global.asa file seemed really nice, but am I understanding correctly that the application onstart event is fired ONLY when the server is started/re-started or when the FIRST user logs onto an ASP application?
If that's the case, then all the changes I keep making to my Global.asa file are pretty useless, right? (which seems to be the case -- i.e., my pages are not using any of the new information). Code:

I'm using application variables for a web based sales tracking application. I use the variables for stuff like connection string, database name, etc. I store the values in a asp file that is included in a login page. The assignments are in a procedure that I then call on the login page. This is done everytime a user connects to
the login page.
what's happening to the variables? Are they being overwritten everytime a user accesses the page? I'm not checking for the existence of the variables. I just call the routine everytime the page is accessed. I know the values are shared for all users but, I was wondering if I should check for the existence of variables? Will it free up resources? Should I be using locks?

I have this:
1 emailBody = "<html>" & vbCrLf _
2 & "<head>" & vbCrLf _
3 & "<title>Interpreter Request details</title> " &
vbCrLf _
4 & "</head> " & vbCrLf _
5 & "<body> " & vbCrLf _
6 & "<font face=Verdana><b>Interpreter Request
details: " & vbCrLf _
7 & "Requestor: </b><u> <% strFName strLName %></u>"
& vbCrLf _
...
& "</body> " & vbCrLf _
& "</html> " & vbCrLf
In line 7, I need to display the results of the variables strFName and
strLName (and have a space in between the two) but I don't know the proper
formatting. If I just use the & then I get the literal strFname instead of
the value. Could someone please show me the correct syntax for this?

I want to be to call my menu from another file onto my page so that i dont have to add it to every page of my website. The problem is when i try to add it using the include method it says that only one include file is allowed on an ASP. The other include file is my connection string so i cant really take that out of the page because then nothing else will work!
How can i get the menu page included as well as the connecting string?
Have added the code below, i have highlighted the 2 include files that i want to use in blue, i have also left the div tag in for where i currently have the menu which is what i want to take out and have ther include file there instead, if that makes sense. Basically the bit in red i want to be able to remove from all of my pages and add the blue file above the red code in instead, but i dont know how!!!!! Code:

I have an asp page written entirely in jscript with a vbscript used as an include file which one variable on the page must access.
When the page runs, I run into jscript complilation errors when it tries to access the include file (since it is written in vbscript), and I can't figure out how to get the two to work together. How do you get both scripting languages to work on the same page?

At my site I have designed a framework with tabs as below:
(tabs_1.asp)
+----+ +------+ +-------+
| MC | | Cars | | Boats |
+ +-------------------------
then, into tabs_1.asp I include another page
(tabs_1_2.asp)
--------+ +--------------
| New | | Used | | Crasched |
+-----+ +------+ +----------+
Works fine so far... Here comes the problem...
The file tabs_1_2.asp has an included page (data.asp) witch doesnt appear...
When I look at the sourcecode from the webbrowser it seems to have been included but nothing is visible.
Is it inpossible to make several includes in the way I described?

How can I include a .cgi file in an .ASP file?
I've tried #include, Server.Transfer, and Server.Execute (yes, I know the last two are
only for ASP, but I tried it anyway).
If I have to, I guess I'll use ASPHTTP to do an http call to the file but first I wanted
to see if there was a more elegant way to do it
Is there an efficient way to include the output of a .cgi file in an ASP file?

I do almost exclusively ASP on IIS, so I'm stupid when it comes to dealing with flat HTML on Linux/Apache.I have a static site on a Linux box where I want to do an include on an ASP file on an IIS box, and can't make it work.
I've tried <!--#include virtual="http://where.com/abc.asp"-->
and <!--#include virtual="http://where.com/abc.txt"-->
The ".txt" extension try was in case it's true what I heard that IIS won't let a remote server execute an ASP in an include file.
Also tried <!--#include file=...", even though I know from experience that Apache requires "virtual," not "file."
And also tried <!--#exec cgi=...".
NOT drawing any errors: the generated output just repeats the "<!--#include..." line instead of outputting results from the ASP file.
