COM object btw ADO and VB client

I'm going to decide a middle COM object that using ADO objects to access a database server, to make use of some central security rule. However, if i write the methods for accessing database, then VB clients can't use the data controls to have database ability. How can i make the control that can be used in VB, but still have database bound ability ??

AFAIK you'll have to write an OLEDB (simple)Provider. VB Apps can than use that for data binding.
