The thread is very interesting indeed, and the effort to replace VB6's long-outdated control palette is really worthwhile.
I'd however rather not rely on the supplied ActiveX .DLL's but compile the needed .CTL files/bundles directly into the resultant VB6 .EXE file. The reason is .OCX's are
huge (it happens very often when an .OSX is written in VB6 rather than C/C++) while .CTL's allow for selective compilation of features useful for the actual project, and you can even delete irrelevant features of the individual controls to further reduce the final .EXE size.
I've looked through the sources and I confirm that the author does know his way around
vbAccelerator.com -- the VB6 gurus' Mecca of hardcore VB6 programming.
