Global Variables

[Tina]

I would like to know the preferred way in which to define, store, and
retrieve global varialbes in asp.net applications. I have read through past
threads here and have seen mixed advice. Some say to define them in
global.asax but I can't seem to reference them. Others say that they must
be defined in the session_start and that they cannot be simply defined in
global.asax. Yet others say just put them in any class anywhere and
reference them.

It seems the right answer would be defining them as session variables but I
can't seem to reference them with session.myvariable
Thanks,
T

If you want the same variable across the application, you use Application
variables and create them in the application_start event. If you need them
individually for each session then you use session variables. You don't
reference them assession.myvariable, it is actually a collection so you
would reference them (in C#) as session["myvariable"]. Just remember that
these are kept in server memory so if you have lots of sessions this can be
a performance drag.

Hope this helps,

I am trying to make it so a user can set a power level, and a ball will move a certain distance based on the power.

I created a text field for the user power imput in sprite 3. The scripts for the button, and the ball are below.

It works aright the first time you click on the button, but after that the ball stays stationary. Any tips would be helpful. I'm new to this.




-----------button script---------

global gPower

on mouseup me

gpower= sprite(3).member.text

end

---------ball script----------
global gPower
property my
property xvel, xaccel

on beginsprite me
my=sprite(me.spritenum)
xvel=0
xaccel=.1

end

on exitframe me

xvel=xvel+xaccel
if xvel>gPower then
my.locH=my.locH
else
my.locH=my.locH+xvel
end if


end

Hey it's me again,

I am wondering if there is a (secure) way to create a variable that is
global. For example, I have an include file right now that defines a number
of arrays for site configuration - eg:

$FilePath = array ("Logs" => "MyLog/", "Templates" => "MyTemplate/");

Lexically speaking, this is fine from the main script. The scope of the
variable resides within the main script. However when I go into a function
it is no longer in scope, obviously. I can always pass the information
through an arguement ie

WriteLog($FilePath['Logs'], 'error.log', $ErrorNum, $ErrorDetails);

This works fine, however, it is a little cumbersome. I know avoiding
use of global variables is good programming, but in this case it would make
life much easier if I could define a few global variables. Can someone
please tell me the best way to do this?

Thanks
/Aaron

(a) The 'global $FilePath' statement to bring the global into scope.
(b) The $_GLOBALS array, visible from all scopes.

Im having trouble understanding where I put code exactly. Can I have global
variables with serverside script?

When I create a variable outside of any functions it doesnt seem to be able to
be read from within application functions (like application.connect). Can
anybody point me in the right direction of understand how this whole dynamic
works?

I seem to remember reading something about the FMS Framework using _global for
specific purposes (don't remember exactyl what it was), and therefore using
_global elsewhere wasn't recommended.

I like to assign variables to the application object (FMS creates the
application object for you when the app starts) when I need a global var.

application.myVar = "someValue"

Now you can reference that application var from anywhere in your SSAS by using
application.myVar

[ekameleon]

Hello :)

you can use the _global in SSAS ... it's easy


in the main.asc :

_global = this ;

and now you can use this scope reference to call the global target when
you want.

All class in SSAS must be implemented in the global scope. The _global
scope it's the root environnement of the main.asc file.

For me it's a bad idea to override the application object with all the
global methods...

EKA+ :)
