Carlos,

I'm just not explaining it clearly enough.

I have a class cntReportControl it contains cntAllReports, opgReportDestination, chkSummary and cmdDoReport. It gets subclassed within the project classlib. Within the subclass I put instances of cntReport inside cntAllReports each one of these hold all the code for the reports. The subclass is put onto a form at design time (what I called dropped onto), so it's the same as AddObject, but it isn't done at runtime.

The form is the parent of the container.
