I just finished building my new COM project (C#, .NET 3.5). This project will be called by a VFP application. It's working great on my development machine, but now I need to know how to deploy it on the user's machine. Click Once isn't available for this kind of project, so I guess I'm stuck with manually distributing the DLL. So, where should I put the DLL and how do I register it? BTW, the 3.5 framework is already installed on the user's machine. TIA I've really never used RegSvr32 with .Net assemblies, rather I use the regasm with the /codebase option: C:\Windows\Microsoft.NET\Framework\v2

I use cwebpage_src code and I need to update some HTTP request headers while clicking on links. As I understand it can be done with self implementation of IHttpNegotiate->BeginTransaction. But how to get my IHttpNegotiate implementation called?? Thanks! Although I have no experience of writing one, I believe that you need to write an asynchronous pluggable protocol , as recommended in this thread . Details of how and why to do this are scattered around the web in various places, but the best exposition that I've read is in this post by Igor Tandetnik (abridged here for brevity): There are
