undo-redo for listview

[Jay]

I need to implement an undo and redo for an entire row in a listview
containing approximately 10 columns. I'm not sure of the best way to
implement this. The only thing that I've thought of is a stack
implementation. I need to be able to undo a delete, an insert (add), a
movement within the list

Any ideas?

Thank you and any ideas would be appreciated.

Just my $.02...

I've never implemented a real undo/redo sort of thing myself, but
here's something I *have* done that might give you some ideas - it's
(sort of) an undo/redo for navigating a series of images. I use two
arrays, one called prevPic() and one called nextPic(). prevPic() is
the undo stack - every time an image is selected, I do this:
ReDim Preserve prevPic(UBound( prevPic) + 1)
prevPic(UBound( prevPic)) = thisPic

(thisPic is a numerical index for another array that holds all the
image names.) To undo, I just step backwards through this array. When
an action is undone, it's pushed onto the nextPic() array in a similar
manner, so redoing is just a matter of stepping through that array.
