My understanding was that you wanted to change the eventArgs.Succeeded property.

I simply did:
and that changes it from the default TRUE to FALSE.

It can have easily 5000 - 7000 bytes per one data change notification - are you OK with that?

It has a ProgID of "System.Exception" so it should be creatable using that, but since we instruct our users to import the type libraries including the "mscorlib", there should be a wrapper class for in Delphi too.

Let me see.... yes, it is most likely CoCLRException, in the imported mscorlib_TLB.pas.

I understand now.

With the Succeeded property, it is similar to those before. It is also derived from something else. In this case, it is derived from the (read-write) property Exception. Succeeded is false when Exception is not null, and it is true when Exception is null.

So, if you are not interested in details of the error (exception), you can just "transmit" the boolean Succeeded value. Then, on the receiving end, when Succeeded was true, simply keep the Exception at null. When Succeeded was false, create instance of any Exception or some class derived from it, and assign it to the Exception. That should do it. You can even set its exception text to something to indicate "Due to transfer limitations, the true type of the exception, its message and other details are unknown.".

Best regards

I am sorry but I do not understand you now. Please try to formulate it in a different way and better.
