In Migration to 2018 COM Wrapper does not work

[Anonymous]

Dear Community,

I have migrated my ObjectARX app to 2018, and everything works fine, other than the COM Wrapper for the Properties palette. When I select a custom object, it does not catch if any object is selected.

I was careful to change the include files and libraries from 21 to 22, update the references, and so on.

When I load the COM Wrapper ARX file manually, it loads and does not show any error.

So I am stuck and ran out of any idea how to proceed to find the problem. I would appreciate your insights.

I found a log file, InfoCenter.log, in which whenever I load my application it says:

6/13/2017 7:56:51 PM: System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {CEE92F99-D9C7-4E46-9AB7-E3F705B9A543} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

 Attempting to load from registry

I checked the registry and I could not find that CLSID, and definitely it's not one of my projects' UUIDs.

Did any of you have seen this before? or if you know how to proceed to solve it?

thanks

Can you please share non-confidential sample project, I have a look at it.

Try running AutoCAD as administrator (or disable UAC) 

If the COM Wrapper is correctly built, it should be able to self-register when running as admin.

This is not the case when running in normal mode even if your user is local admin. You'll probably see the message "Failed to register COM server" on the command line. And this is because UAC prevents the AutoCAD to alter HKEY_LOCAL_MACHINE and HKEY_CLASSES_ROOT in the registry. 

But next time you run AutoCAD, normal mode suffices as the module then has been registered.

What we do, is to have all the registry keys necessary for the COM Wrapper to function properly included in our Installshield installer for our applications. Then we don't have to require the user to run AutoCAD as admin once for the properties to work. 

One way to see which keys and values to set, is to export the registry before self-registering the modules, and than export the registry after, and do a compare using Regshot or some other tool.

I had the same issue, calling a classname was not possible until I have changed my R value to 22.0 in the .rgs 

HKLM
{
	NoRemove SOFTWARE
	{
		NoRemove Autodesk
		{
			NoRemove ObjectDBX
			{
				NoRemove R22.0
				{
					NoRemove ActiveXCLSID
					{
						val YourObject = s '{xxxxxx-xxxxx-xxxxxx-xxxxxx-xxxxxxxx}'
					}
				}
			}
		}
	}
}

Check that your C++ code is registering to the correct version of autocad.

check IDL file. mb you forgot to change importlib("axdb22enu.tlb")

if the problem is in permissions, Alexander Rivilis have told me how to register DBX for a current user without any permissions. so, i can share it 

1. totally remove HKLM from your wrapper RGS file. 

2. use this code to register a dbx.
