Hi,

I'm trying to use what I'm learning from this book and experimenting with a test app. I have built a folder hierarchy and created a web app pointing to the top level folder and virtual directories pointing to the subfolders. However, I notice that application variables that I assign in my global.asa file are sometimes, but not always, unassigned as I switch to a different folder. What could be causing that, and how can I ensure that these variables stay assigned throughout the life of the app? Or am I missing the larger picture that there is a one-to-one correspondence between web apps and folders, and that it is just a fluke that these variables sometimes do remain assigned?

Application variables should keep their value for all subfolders between the "application root".

The "application root" is something you can define yourself using the IIS Management Console. If you change a directory into a Virtual Directory, it will act as a different application with different application variables (not 100% sure if you do need a global.asa file, though).

So, as long as you have a single application root, all other normal folders beneath it, should be able to read and set the same set of application variables.

If this is not the case, maybe you can post some code and describe your situation in some more detail. AFAIK, the way you describe things shouldn't happen.....

Thanks for your your prompt response. So is the issue then whether I use a physical reference to the subfolder or a virtual directory, the former being part of the same application while the latter being a separate application?

I am not sure what you mean, but consider this example: If you look at these four folder, you'll see that the wwwroot and the MyNewApp are both a separate application (that is, if you changed MyNewApp into a Virtual Directory through IIS).

The folders Admin in both example will belong to their parent application. That means that ASP pages in the First Admin folder cam't read application variables created in the other Admin folder (or its parent).

By changing your normal folders into Virtual Directories, you'll create a separate application scope.

Does that make sense?

Absolutely. Many thanks. Just tried it by "removing" the virtual directories I had linked to my physical folders and my application variables were pretty much saved. So, as you have explained, there is a 1-1 correspondence between web apps and virtual folders.

Thanks again for your help.

P.S. I wonder if you can help me with the other message I posted earlier regarding writing to web directories using the Record object's CopyRecord method. I'm really stuck on that one.

Yeah sure. Is it this one:

or this one:

For the first one, you should indeed check the "Script Blocking" feature of your Anti-virus program. There is no need to disable the entire program, just make sure that script blocking is turned of.
If it's the latter, can you post the code you're having problems with in that thread? I don't have the book, so it's hard to see what's going on. I may take until tomorrow until I have the time to look at it.....

Cheers,

Imar

It's the

topic, and I've added the code as a reply to that topic. I tried that one as well with scripting off in NAV with no success.
