VB6 comes with an ActiveX control named MSWLESS.ocx (“Microsoft Windowless Controls 6.0”), which contains lightweight equivalents for these standard controls:
WLTextWLFrameWLCommandWLCheckWLOptionWLComboWLListWLHScrollWHVScroll
The controls have lower resource consumption than their regular counterparts, as well as better performance. Because they don’t have windows, they don’t have handles or DDE capability, and they can’t serve as containers. They’re also not installed automatically in the Visual Studio 6 setup, so you’ll need to dig them off your CD manually.
