>>In Rick Strahl's white paper, he states that you cannot bind objects to RDS data because originally when you create the RDS object and build your cursor, the cursor can fail.

That's what I thought until I tested it. Actually returning a .F. from the load will prevent the form from loading but as Erik Moore has pointed out it is not a documented feature. Actually this has been available since VFP 5.0.
