The References dialog in VB6/VBA shows ActiveX controls that are registered in the Windows registry. The portable iGrid demo is a special exe that 'knows' how to find the iGrid and ImageList OCXs in the OCX subfolder without having those OCXs registered in the registry. The portable demo does not register them in the registry - that's why you do not see them in the references dialog. Only the full demo installer does this work as a part of the installation process.
