i currently write an applet which shall import data (Usernames, passwords, etc.) from e.g. Excel dynamically into gridfields which are processed by my applet. If the user changes for example his password the new password is stored in the gridfield and saved into a excelsheet.
Which is the best way to avoid long loading times?
How can i open excel in the background?
Is it possible to save data within the applet (without config file?) by the users?
thanks for help
