Reading data
To retrieve data from a saved Shared Object, just use the following syntax:
stored_user_name = local_data.data.user_name;
stored_user_age = local_data.data.user_age;
Don't forget that you still have to create the local_data shared object first. Now, the user's name is stored in a variable called "stored_user_name" and the user's age in the variable "stored_user_age"and you can use it anywhere in your movie.
ou can store more information in one Shared Object file in the same way. Similar to the way how we have saved simple text variables you can store whole arrays and other objects.
Important Point
There are some important things to remember when using the local Shared Objects in your movies:
The primary drawback of shared objects is that it can be overwritten/disabled/erased by the user (right click on the swf, and click on settings), so avoid to store information which is absolutely necessary to let the application work properly. Think of it as an additional feature.
The amount of the information you can store in a local Shared Object from one domain is set to 100 kb by default. If you will try to store more information, the Flash player will ask the user for a permission to increase this limit. Be sure the stage of your movie is at least this is the minimum size Macromedia Flash MX requires to display the dialog box.
