Referencing next record for a checkbox

[Chad]

Here is another though i had as well, could someone
please tell me how to reference the next record for a
checkbox? To be a little more specific:

in the code

For intIndex = 0 To ListBox1.ListCount - 1
Listbox1.Selected(intIndex) = True
Next intIndex

I would like to perform the same thing for a check box
that line 2 does for a list box. (sets it equesl to the
record associated with intIndex).

Thanks again for any help you can give,
Chad
