Presuming that first line is defined at the very top of the codebehind
outside any of the Subs.

But If I set it at the class level, but what's available to me when I
set it? At the time I'm setting it, do I have access to session
variables? Do I have access to values of controls on the page?

When you declare at class level, the variable is created in the constructor
of the page. At this point, you do not have access to session variables,
cookies, etc. yet, but I think you can access controls after
Initializecomponent is called. However, in the constructor you could
execute database queries or any other non-ASP.NET code and populate the
variables.

If you need to populate class variables with ASP.NET data, wait for the
Page_Init or Page_Load fire. By this point of the page lifecycle, the
ASP.NET session variables, cookies, etc should be populated in HTTPContext.

Does this answer your q?
