MrNobody,

    I would say create a typed data set. You can use the designer to create
the data set structure in the editor, and then it will create a strongly
typed data set (with properties that you can access instead of using field
lookups). It should help with this sort of transition, and help reduce the
amount of code that you need to change.

    Hope this helps.
