Solved few errors but stuck in those---

3107, Reserved method must return a value (Integer/String/Buffer/Package/Reference required for _DSM)
3124, Switch expression is not a static Integer/Buffer/String data type, defaulting to Integer
3130, Result is not used, possible operator timeout will be missed

Can anyone tell me how to resolve this problem and any help should be apritiatable.
