ActiveX Controls have been deprecated by Microsoft in the latest versions of the Windows operating system in favor of the
DotNet framework and its controls.
While MAXScript still supports ActiveX controls, these have to be installed and registered on the system to be accessible to MAXScript.
As a replacement of ActiveX controls, MAXScript supports DotNet controls in 3ds Max 9 and higher.
See the topic Converting ActiveX ListView Control to DotNet ListView Control for an example of switching existing ActiveX code to DotNet.
The following example will not work on your system unless it has a ListView ActiveX control installed.
