>What is the your preferred method to return more than one value from a form? Use an array? or pass a reference to a non-visual object? Or some other way?

Roi and Ken both gave good suggestions, but if I wanted to make this as simple as possible for myself and for other programmers, I would accept output parameters passed by reference.

For an example, check out the GridHitTest() method. That returns a value, plus 4 values gained by passing variables by reference.
