I think it is not VB6/Windows issue. It is AutoCAD2018. Up to AutoCAD 2017, in AutoCAD\s VBA editor, when any Acadxxxx class/method/property is highlighted in Object Browser window, press F1 button, or click "?" in Object Browser window's up-right corner, AutoCAD VBA help document opens. It is not any more with AutoCAD 2018. While there is less and less use of AutoCAD VBA/COM API, still, losing this convenient help document sucks, because AutoCAD's COM/VBA help document is (was) the best help document among all AutoCAD APIs' poor help documentation.
The AutoCAD ActiveX/COM documentation is still available as a CHM file, but it seems that the CHM files are not currently being installed to the correct folder or the Help in the VBA IDE is not finding the files in the correct folder.
The CHM files you are looking for can be found here C:\Program Files\Common Files\Autodesk Shared\en-US:
- acad_aag.chm - Developer's Guide
- acadauto.chm - Reference Guide
It looks like if you copy the CHM files from C:\Program Files\Common Files\Autodesk Shared\en-US to C:\Program Files\Common Files\Autodesk Shared, then F1 works correctly from the VBA IDE; not sure if that will fix the issue with VB6 though but it might since the CHM files would now be located in the same folder as the TLB files.
Additionally, the ActiveX/COM documentation can also be found online with the rest of the AutoCAD Developer documentation at: http://help.autodesk.com/view/OARX/2018/ENU/
