Hi All,

Hello Experts!

I have been stumped at this all morning and can't seem to figure out why this data entry form doesn't seem to release completely!

I used a DataEnvironment subclass as my 'data layer', a Custom subclass as my business object.

In my data entry form (also a class), I then assigned DEClass and DEClassLibrary to my 'data layer'.

I then drop my BO class on the form, which has a property oDataLayer, which at design time, I assigned an '=thisform.mydatalayer' as its value, pointing to the DE.

All UI calls are made to the BO, which in turns relays the request to BO.oDataLayer.

Everything worked perfectly: Adding, Modifying, Deleting...

When I close the form, I can still see in the Data Session Window! drats!

I used the same data entry form class using native tables, but it does not leave dangling references.

Thanks in advance for any help.

More Power.

Dennis
