I suppose this question is more general than working with COM components. I have a .NET client written in C# and COM component written in pure Win32 API. Client side uses this component to perform some actions. How to know on the client that component did its job?
I think it may be socket/pipe, with component writing to it about results, and client reading from it displaying progress to the user. What is the best way to do this?
