The answer to your questions really depends on how you intend to initiate the update to the shared dataset. If the update will be done from the first form (which is what I'd recommend) then all you really need to do is pass the dataset to the other form, bind the data, and let the user have at it. Remember, your just passing a reference to the same set of data. The changes made to it from the second form will be available once control returns to the first form. Then just save it as you normally would.

Actually, I've done this quite a few times, and truthfully, the second form may be able to be base on a .net form instead of a MM form...depends on what you're doing with that second form.
