If the documents you want to open are on the web server, you can open them via a url, for instance:
If you want to open local files (on the client), use
client_host('cmd /c start <your file>')
actually, i'm working on oracle developper suite 10g in my local machine, not in client-web server environment yet !! i'm doing some tests, , so is it possible to try the method u gave me (web.show_document or client_host) ?????
The process is the same whether your Form is deployed to an application server or running locally from the Forms Builder - you still have to use one of the methods listed by InoL.
