The use of object varaibles, resultset and foreach loop in SSIS

I've recently been involved in documenting an SSIS package made by our lead developer and there is a foreach loop that he used to loop through a resultest from a query. An object variable is used to hold the resultset temporarily and the foreach loops through this result to repeat some actions. Since this trick is pretty new to me, I hence document a very good tutorial here to keep a memo.
