Updating progress bar in MFC dialog from .NET C# D

问题:

I have seen this article but I need the reverse and find it confusing.

I have a C# DLL that is performing a lengthy task automating Outlook using interop.

This DLL method is called from my CDialog function in MFC.

My dialog has a progress bar control on it. Is it possible to update this progress bar in the dialog from the .NET DLL?

Does my question make sense?
