>Same error - "Object class is invalid for this container". I just created a dummy vcx with one (untouched) form class in it, added it to the project, and tried to ctrl+drag and drop the rtf control from where it was into this classlib.

I tied it as well with a couple of my OLE classes. I then tried creating a class based on VFP container, add the RTF OLE to that. Now it can be added to another VCX without error message. So there must be something about the OLE class that prevents it from being added this way and can only be added manually.
