check out wwWebPage::RegisterCursor if you are using WC5...
and one addition I would make to
use in tempCursoris
use in select(tempCursor)no error will occur if it does not exist...
Rick,
Thanks. I think I have structured the app to operate in a stateless manner (you finally got me to see what that was). My concern now is how to close the cursors created by visitors. Since I can never know when they leave, I don't see how I can close these files.

To access the site each user must login and I validate the login information against data in a FoxPro table. Once access is granted I provide access to information primarily by running queries, producing cursors and displaying the results in either a form or a grid. While this all works I'm not sure how Westwind handles multiple users. The query is producing a cursor with the same name each time that piece of code is hit. Does each user get their own set of temporary tables? I do not presently have a logout button so I'm not sure what's happening to the temporary tables created by a user visiting the site.
Web applications are stateless which means every hit is a new session effectively and it's your responsibility to restore the appropriate environment on each hit. This is why every request typically has some sort of ID that and action that tells the backend what action to perform and what record or data to perform it on.
There's no 'database session' for a user. Each hit is a new session and it's your job to "re-attach" to a session on each hit. This means that you need to keep track of the users state either in the database or using the Web Connection Session object. IOW, you as the developer have to track state.
Effectively this means that on each hit you have to restore the environment you need to run your logic. This might mean re-loading the user data based on the user's ID. THis might mean reloading the customer data that the user just entered to update it when they click on Save. Stateless programming basically means that every request has to be self-contained and set up its environment on each request.
A couple of weeks ago I mailed a letter and check. The check is not engaged in I wondered if you have received it
Got it. I'm not very good about putting checks into the bank quickly :-).
Aloha,
