A workaround would be to create a cookie that you can use from either spot Scott ...

variable of variables
Say I have 2 scenarios and I want to use a different variable depending on which scenario applies without coding this logic. So I could have a database table t_variables which has: Scenario: Variable: --------- -------- 1 v_name 2 v_company In my Powerbuilder code I'd have values in v_name & v_company. What I'd like to be able to do is to select which variable to use from the table and assign that to something, e.g. select variable into v_variable from t_variables where scenario = 1 so at this point v_variable would be 'v_name'...

After a looong night managed to change Session mode from inProc to SQLServer but still can't get the session variables to be saved
Hi,  I ran my Shopping Cart project and somehow everything worked fine(while in inProc), session variables were saved fine.

Getting the same damned 'nulls' instead of the saved objects. private void Page_Load(object sender, System.EventArgs e)         {...

State management upon session variable changes
I noticed that whenever a session variable is changed...the application knows about it and suddenly restarts session. My question is does restart "ALL" sessions or only the active sessions for which the variables changed? Imagine a "multi-user" application all with different states and an administration panel that lets you change session variables.  In this case, my question has to do with the question that if Company X changes his session variables, will only Company X's sessions be reset or will all "sessions" be reset?  Hope that makes sense. ...
