Visual studio 2019 doesn't generate wrappers for Activex/OCX RRS feed

  • Question

  • Back in VS2017, when referencing an OCX two files were created and referenced:

    • Interop.XYZLib.dll
    • AxInterop.XYZLib.dll

    from there I was able to create a wrapper around AxInterop.XYZLib.dll that exposes the methods and properties of the OCX as if they are native. Now after installing VS2019 only Interop.XYZLib.dll is generated. Even if I go back to VS2017 the behavior is the same, only one is generated, and trying to use it causes a catastrophic failure. Other answers suggest to use AxImp.exe, I tried, only to have an error saying "Did not find a registered ActiveX control in ...", that's confusing since the OCX is registered with RegSvr32.exe, any ideas?

    Thank you

  • Hi Dave, thank you for the input, I used AxImp.exe as described on the link you've provide and was able to make it work, well sort of..., it does generate two files but something seems to be odd about it. VS2019 doesn't seem to like those files, and why now it seems broken? before Visual Studio was able to generate those files for me now it doesn't. I'm sure it is a setting or something silly, but I'll keep looking.
