Rick,

Returning .f. in load prevents form from instantiating. If it were not so, none of my (custom) DE stuff could kill the form if I had a data problem!

>>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.
>>
>>You couldn't do this in the init, of course because the your form objects have already been initialized and the form would fail, being unable to bind the objects.
>>
>>He then goes on to say that you could place the code in the load but there is no easy way to abort the process if the cursor fails to load. This is the part I do not understand. If the cursor fails to load, why can't you just return a .F. in the load?
