VBX v OCX

by John Mina - GUI Computing

32 Bit OCX’s by third party vendors are a bit scarce at the moment, and with the few which are available, the main issue was to equip the OCX with the features of the VBX or DLL equivalent.

All have a new tabbed Properties dialog (see below). Some have one or two additional properties, in some even one or two of the original properties from the VBX have yet to be included. But, whichever way you look at it, the 32 Bit OCX is what most of us will be using.

It is not fair to judge any of these controls on the basis of this first look - for good or ill. What we're trying to look at here is where they differ, and what problems or benefits those differences might bring. Both Desaware and Videosoft actually have OCX versions either shipping or in late beta that we could base this article on. Not all vendors can say that.


Let's take a look at a couple of OCX controls and compare them with their VBX bretheren.
