How to run OPM sample from Kean's blog?

[Anonymous]

has anyone tried to get the following sample to run from c# express?

re: Modifying an AutoCAD object’s state via a dynamic property defined using .NET

URL:

http://through-the-interface.typepad.com/through_the_interface/2009/05/modifying-an-autocad-objects-...

This post has link to sample project for accessing property pallet, but I can't figure out how to make it work.  There is a mixture of c++ and c# and I can't find what modules I have to save to acad's folder (per kean's instructions) and what reference to use to replace the one that doesn't load when I try to run the sample project he supplied.

When I run the csproj file in the downloaded sample project a reference comes up "missing"

Warning 1 The referenced component 'OPMNetExt' could not be found.  

There is no OPMNetExt.dll in the downloaded sample, there is an OPMNetExtSample.dll and I placed that in the acad folder as he directed but that isn't the right one.

I also get the error:

Error 2 The type or namespace name 'OPM' does not exist in the namespace 'Autodesk.AutoCAD.Windows' (are you missing an assembly reference?) 

and the error:

Error 3 The type or namespace name 'IDynamicProperty2' could not be found (are you missing a using directive or an assembly reference?)

It seems you do not understand the difference between static and dynamic properties of entity. You can see the added dynamic properties only in the properties panel (OPM).

"asdkOPMNetExt.dll" not load in Autocad 2019 and 2020. After loaded this .dll Auto CAD 2019 & 2019 generated error i.e. Unable to load asdkOPMNetExt.dll is incompatible with this version of AutoCAD.

Please provide solution as possible.  I am waiting for your valuable response.

I'm so sorry, I was meaning to write AutoCAD 2021. So sorry... I will edit my question.

You should use ObjectARX 2020 if you are using AutoCAD 2020...

Hello,

This topic is popular again with the coming out of the new 2025 version. Anyone has the new build?

With kindest regards,
