Flex Examples

The following example shows how you can determine the current security sandbox type for a Flex application by checking the static, read-only Security.sandboxType property. You can also check for specific sandbox types by comparing the sandboxType property to the static constants in the Security class (LOCAL_TRUSTED, LOCAL_WITH_FILE, LOCAL_WITH_NETWORK, and REMOTE).
