Hi, I have this problem:

I use some classes in my pages that I create using:

<% class MyClass

public function MyMethod()

end function

end class %>

I create an instance and store it on a session variable:

set session("MyClass") = New MyClass

so I can get the object in every page of my app, using:

set MyObj = Session("MyClass")

In the page I create the instance, I can acces the class methods with no trouble, The problem is that when I'm in another page ASP recognize the session variable as an object, but can't access the class methods.

What am I doing wrong?

Sorry about my engilsh.

Thanks.

If you wish to have this "session" variable avaliable to every page on your site then you should place it into the global.asa file in the root directory of your site. Place this code in the file...

<SCRIPT LANGUAGE="VBScript" RUNAT="Server">

'Application_OnStart runs when you start IIS
Sub Application_OnStart

class MyClass

public function myMethod()

'your code goes here...

end function
end class

'Create and instane of "my class" in application scope
Application("MC") = New myclass

End Sub

</SCRIPT>

Phew! Now to call the instance of myclass from anywhere in your site just call Application("MC"). You can use this in the same way, same code and all with a Sub Session_OnStart which will create the object when the user's session starts.

I wouldn't use a class for this unless it was absolutely necessary, classes get sort of corky in asp...

Hope I helped,

I don't want an Application variable, I want every user to have their own objects, so these must be session variables.

And I don't want to create these instances on every session start neither, just when is really needed.

Thanks anyway.
