>This approach may work for you now, but it has some limitations. For one thing, using VFP cursors throughout an n-tier system won't work unless all the tiers are VFP.

Good point. I meant that the VFP tiers would use cursors for their actual operations. If necessary they could pass results to non-VFP layers in recordsets or XML cursors.

I meant to pass just This, but This.ControlSource would be OK too.

Thanks for your input, Barbara.
