Before you begin:
An API ImageList object is created and populated with icons extracted from specified executable or library file. Then the ImageList is linked to a ListView control on the form. Each item in the ListView represents an icon.

    My comment:
    May 24, 2007: code sample rewritten from scratch

    ImageList ActiveX control wraps several API functions in comctl32 library, like ImageList_Create, ImageList_GetImageCount and so on.

    While writing this code sample, I found the API ImageList object much more reliable and predictable then the ActiveX one. For example, the ImageList_Add successfully adds new images to the ActiveX control. But that does not affect the Count property of its ListImages collection.

    The hImageList handle of an empty ActiveX ImageList control is always zero. To apply any ImageList API function to this guy, at least one image must be added. That I found an inconvenient feature also.
