Sometimes you need to know if is a specific instance of an object, is the one you’re looking for.objptr() provides a nice VB-ish way to compre object pointers.
So, you have collection of objects. To find the instance of the object you are looking for (ignoring keys and bad design, granted), use this code:
private function IsMember(po_obj as Member) as objectdim o_obj as objectfor each o_obj in MyCol if(objptr(po_obj)=objptr(o_obj))then 'our specific instance matched set IsMember = o_obj end ifnext
