Lightweight controls, sometimes referred to as windowless controls, differ
from regular controls in one significant way: They don't have a window
handle (hWnd property). Because of this, they use fewer system resources.
You create a lightweight user control by setting the Windowless property to
True at design time. Lightweight user controls can contain only other
lightweight controls.

that is all for now...Mike

I am no expert, but I can tell you this. Many of the controls used by VB are
enhanced basic windows, while others are simply basic windows.
For an example. A label is a basic window, while a textbox is an enhanced
textbox. A command button is a basic window, while an option button is an
enhanced command button. I would guess the lightweight controls are the
controls that are basic Windows windows, while the heavy, or non-light
weight, controls are the enhanced windows. I know this is not worded to
well, but I hope you can get the gist of things from it.
