is there any possibility to use an ActiveX component from Lazarus on Windows - at least low level. Any HOW-TO / example? Its about a hardware driver which is only accessible through an ActiveX DLL.

2.3.1 is able to start and instrument word or IE using dispatch interfaces.
See examples in winunits-base/examples.
I don't know the exact status of 2.2.4 in this regard. A lot of the windows headers parts are merged, but I don't know how much of the languag and objpas/variants units parts are merged.
For 2.2.4 I'd try to get the IDL description of the OCX, and then translate it to FPC taking winunits-base units (like shlobj) as an template.
There are no FPC tutorials yet, but this is fairly close to how Delphi does it, so general Delphi tutorials should be fine.
