Global Scope Variables
I am making a testing project to get my hands on ASP classic. I have a question about Global Scope Variables e.g in PHP we make a file where we define some values which are global, e.g site URL, site title etc, and then we can include that in any page to get that value.
I read Global.asa works very good in fact we dont need to include that in every page to use stuff within this file. I read some examples but they are mostly about functions in this file. Can anybody guide me please how to define variables in Global.asa to use them sitewise?

I have a piece of vbscript that returns the user logged on to the machine. it is as follows:
<script language="vbscript">
Set WshNetwork = createObject("WScript.Network")
stringUser = (WshNetwork.userName) 'store username in variable stringUser
document.write("Username: " & stringUser) 'output value to web page
</script>
Now I need to use the value of stringUser on other pages of my asp application for database queries, form values etc. I have tried to call stringUser from inside <%..........%>, but it doesn't recognize the variable. Everytime I try to output the value from wthin asp code, it just appears as blank space. Any ideas?

There are many web sites on the server - each has a virtual directory pointer to a common directory containing frequently used routines. Scripts run from the virtual directory appear to have no access to session (or application) variables. Is this expected behaviour? Or have I yet to track down a bug?

I have a couple ASP applications running on my server (non .NET)
I would like to be able to get a sum total of how many active sessions I
have running.
I can do this within each app individually as I can just use an Application
variable and add/subtract as the sessions are created or deleted.
I am trying to come up with a sum total of all sessions between the two (or
more) apps running on this server.
That way I can tell if it is safe to reboot the box without affecting anyone
or not.

I'm trying to add a "user-verifacation" thingy to my site.
my problem is using/accessing session variables.
all the tutorials say that the global.asa should only have
the script tags (<script...> & </script>) and inside the script itself
only have the application/session onstart/end.
I've created this global.asa file and put it in my site-root folder:
<script type="text/javascript" language="javascript" runat=server>
function Session_OnStart()
{ Session("LoggedIn") = "NO"
}
</script>
but i can't access the session variable Session("LoggedIn")... from any page.

Is it possible to create a global variable from within a Sub
so it is available to another function in the same web page?
I want to tap a database for information within a Sub procedure
but end the Sub after assigning the values to global variables.
Simply defining the variables as global (outside the Sub) and
setting them to empty strings does not do the trick. The variables
don't persist after the Sub procedure is complete.

i have a logon page, i create session variables for every person who logs on, but when their session times out, i want to redirect them (or have a popup window) that tells them that they have been logged off, but i have no success.' global.asa:
<script language="vbscript" runat="server">
Sub Session_OnEnd
Response.Redirect "loggedout.asp"
End Sub
</script>
but it doesnt work, i set the timeout to 1 minute, and i lose the session variables, but i cant seem to redirect them to the loggedout page!

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 am trying to run a Session_OnStart Script based on a Session variable that is created on a .asp page. The problem is that when I reference the Session in Global.asa It has no value but it has a value on the .asp page level. Is there a certain way that I have to reference a Session in Global.asa?
What I have is somthing like the following:
Sub Session_OnStart
If Session("NIS")<> "" Then
Run The Routine
End If
End Sub
Based on the above the routine does not run because Global.asa does not seem to get the value of Session("NIS").

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 created a ADODB.Connection object in Session On_Start and tried to connect to the databse On_Start. It is giving errors. Can't have a connection opened only once in a whole applicatio like VB.
The Con variable is available for the whole session but the connection state is not available for the whole session. Do I need to open a connection everytime I want to access a database????

Basically, I have an asp application that uses a database connection,
and I want to declare (create) that connection in an include and use it
throughout the application in various functions. I've tried making the
connection object a public variable, a constant, making the functions
public, passing the connection object in byRef, byVal, etc... I just
can't get it to work. Is this not possible in classic ASP? Code:

Does anyone know of a way to enumerate the local variable scope? The
reason I ask is that I have a function that dumps the contents of
response,request,server,etc... for debugging purposes. I'd like to also
display the local variables.

This has been puzzling me for very long time and no where has
talked about the scope of a 'On Error Resume Next' statement.
When we program ASP(.NET) pages then we usually like to let
ASP(.NET) stop at errors and report back to us. However there
are parts of our scripts that we know an error will be thrown
and we encapsulate that area inbetween:
On Error Resume Next
Err.Clear
'Try block
If Err.Number Then
'Catch block
End If
On Error GoTo 0
This is similar to the infamous try {} catch(e) {} blocks in
Java/C++, etc.
If we forget the last line 'On Error GoTo 0' then our ASP(.NET)
scripts runs over all errors thrown and we find it hard to
find bugs. So the big question is, does 'On Error Resume Next'
go out of scope when it's written inside a block
(eg. Function)?
Function Function1()
On Error Resume Next
'Our code
End Function
When the Function1 call returns, does the outside calling scope
automatically stays as it was (On Error GoTo 0)?

How can I give a user-defined object session scope? From
http://www.microsoft.com/windows200...asp/iiwaobu.htm
I gather that it can be done, but there are no examples. Simply setting
Set Session("tag") = new MyClass
doesn't work.

I'm not sure how to best describe my problem, so a simple example should help explain things:
I have two arrays, called set1_data and set2_data
if I create a variable like so:
firstPart = "set1"
and then assign like this:
copyOfArray = firstPart & "_data"
how do I make copyOfArray reference the set1_array, as opposed to just a string "set1_array" which is what it's doing?
I've had a good rummage round ye olde Internet but couldn't find anything there must be a keyword or function to achieve this?!?

I am trying to put a condition in my Global.asa file based on the server
name.the reason, I want to set a global string as a application variable based on
the server I am on.
I also need to set a coonection string based on the value of the server.
I need to use this connection string to retrieve values from an sp in
application on start that sets a load of global variables so I can't really
do this anywhere else.

I have a site which until this morning, was on a remote server. The structure was that the "site" was actually a folder on the server, as I am designer and use this arrangement to develop sites. Under the root directory, I had modified the global asa file to include session variables. Ok, so I download the site (folder) to my hard drive, and put it in the folder of "MY Documents" called MyWebs. I then opened VB Studio and created a new solution, which is pointing to the before mentioned directory in My Documents. When I pull the site up in IE, the session variables were not being called, and I realized I had not copied over the asa file. So I did so, placing a copy of it in the hard drive's c inetpub wwwroot directory, and also directly in the my docs mywebs directory,and the site's directory as well. It seems it is still not being called.Can anyone tell me what I am doing wrong?

How does IIS 6.0 treat the global.asa file? I had the following problem;
1. uploaded a new site to the win3k server
2. had incorrect db connection string in Session_OnStart in global.asa and website caused errors.
3. Changed the global.asa file to include the correct details. Saved the file. Still got the same errors.
I could not resolve this unless restarting the WWW Service on this server. In IIS 5.0 the global.asa file would reload after resaving it (as the timestamp is updated).
I even waited the next day before restarting the service because I though Session_OnStart expires after my session ends...but the error was still there
in the morning.
Hopefully someone will make sense of it for me. Here is the code (I inherited) in the global.asa
Sub Application_OnStart
Application("DB.ConnectionString")= ""
Application("MaxLoginAttempts") = 5
Set Application("Con") = Server.CreateObject("ADODB.Connection")
Session("Test") = Now()
End Sub
Sub Session_OnStart....

We have over 100 asp pages that reference a table (distribution_components). We added a new column and primary key to that table, so now we have to modify the where clause to include that column (we have to make the new column = to a session variable in the page)
The table appears 531 times in our code. Is there some util or method that allows us to change it globally, other than going to each occurrance, and adding the new column to the where clause.

Basically session_onend will not fire in my global.asa files! I have just made a very simple test to prove its not my programming and it still doesnt fire.
Session_onstart works a treat but onend will not work even if you force the session to expire with abandon. I have tried on 2 of our servers now and it doesnt work on either.
my simple test is this:
Sub Session_OnEnd
application("test") = "hello"
End Sub
Now surely that should work. i obviously have a page that writes that test variable to the page but its always empty.

Set IE 6.0 ver. X to "Block all Cookies" in privacy settings and try
this code in three separate files.
<-- Global.asa -->
sub Session_OnStart
response.cookies("test") = "-1"
end sub
<-- Global.asa -->
<-- testcookie1.asp -->
<%Response.Redirect("testcookie2.asp")%>
<-- testcookie1.asp -->
<-- testcookie2.asp -->
<%=request.cookies("test")%>
<-- testcookie2.asp -->
I get "-1" on testcookie2.asp
Anyone else get the same result?
Why am I getting the cookie in this test?
