Can I request a session variable from a dll. To pass the value as a property would require huge rewritings of code. If not is there any other way I could do it. The scenario is I have a database access dll. This is called from asp or from other dll's. The problem has arrisen whereby I need to pass the connection string to the component as we now have more than one database. Any ideas?
DLL's can't access session variables. You have to pass the session variable to the procedure as a parameter.
If you want to maintain compatability with the current version of the DLL, you could either use an INI file or registry settings for your database connection information, then add a private function to the DLL that is called whenever a database connection is needed.
