I think the only tools you will find for doing this will be the like the one that comes with VMP and the ytpe that are found here in the files section. Hihglightling all controls in the form designer and changing their class won't work for the same reason that just changing the class in the property sheet won't work: you can't change the class of an object after it is instanciated, and when a form is open in the designer, it is instanciated.

It would be fairly easy to write a tool that wlil open every form or clas in a project and change the class of a specific occurence of object. I am sure somebody has already done it, and this may be the tool you are referring to.
