How to check an object in my container, which containes 3 objects, has controls?

I have a container with 3 objects,
objects(1). has the usual number of objects
objects(2) and 3 are blank

MyObject.ControlCount returns 3
myObject.Controls(1).baseclass returns "Container"
myObject.Controls(2).baseclass errors

and although indeed debugger shows value (Object) for myObject.Controls(2) and 3,
debugger also shows myObject.Controls.+Controls(1) and no + sign for Control(2) and Controls(3) so apparently empty. How to check in code for this situation?

I have a recursive setallprops function which errors on Controls(2) = empty control

Regards,
