Hi Dragan,

Thanks for the responce. The way you describe it. It's close to the way things are at the moment. But we're in the process of re-thinking thing. And this came up. So if I need only a few textboxes on my form. It won't add the entire library into my exe. This is good to know.

We have created larger classes that have several of these sub-classed controls in them. These larger classes will handle stuff like printing. And were wondering if we were on the right track. Of starting down a dangerous path.
