control totally disappear (in designer and runtime) , but code concerning
controls remains present and apparently unchanged

Look for Exceptions being thrown in the Form constructor(s).
These mess up both the application at run-time and, more
importantly (to us) the Forms Designer itself.

If necessary, use two instance of the 'Studio IDE, one debugging
the other!

Open the Forms project in one (with the Designer /not/ open).
Attach the second instance to the first's process.
In the second instance, break /any/ Exception into the debugger.
Then open the Forms Designer in the first instance.

HTH,

I find sometimes if I change any code and I mean any in the Designer Section
of the class that inherits the base form, it can really screw things up.
