I maintain a very mature product (over ten years old) that was written in VC++ 6 (MFC). My team is in the process of giving the app a new look and feel. We decided to try to convert the project to .net to leverage the GUI elements; but had too many issues during this process and forfeit the idea. This leads to my questions: 1.Could an application that is compiled under VC++ 6 use Win Forms, or VC++ 2003(or higher)Dialogs? 2.This is more of a secondary question to number 1). Could controls be written in C# or VC++ 2003(or higher)then the assembly or .dll be used by an application compiled in VC++ (MFC) 6? 3.If you answer yes to either question; is there any documentation? Thank you:), -e P.S. My goals is to slowly move the application to the new platform. I am trying to make the application co-exist between VC ++ 6 (old code) and VC++ (maybe .net) 2003 or greater (new code). Since I don't have the option to compile the application greater than VC++ 6.

Thanks for replying, I should of been more specific with the development language. The existing application is coded using VC++ 6 (MFC). At the moment I can't covert (promote) the existing code to a greater platform than VC++ 6 (for various reasons). So I am looking for a way to have new development be written in VC++ 2003(or higher) or C# and try to co-exist with the existing code. So I guess what I'm looking for is an application that is compiled with VC++ (MFC) 6 to have mixed code; the existing code to use MFC 6 components (like dialogs etc..) and the new code to use C#, VC++ 7 code (like Win-Forms etc...). Thanks, -e P.S. My goal is to eventually move the application to the newer platform (in baby steps).

Thanks for the input. To answer your question I had assigned developers to try to convert the application to VC++ 2003. Since the applications is over ten years old it has seen its share of GUI toolkits and some of these toolkits are not converting to the new platform. So one of my goals is to slowly move the application to the new platform. I am trying to make the application co-exist between VC ++ 6 (old code) and VC++ (maybe .net) 2003 or greater (new code). Since I don't have the option to compile the application greater than VC++ 6. Thanks, -e

I maintain a very mature product (over ten years old) that was written in MSVS 6. My team is in the process of giving the app a new look and feel. We decided to try to convert the project to .net to leverage the GUI elements; but had too many issues during this process and forfeit the idea. This leads to my questions: 1.Could an application that is compiled under MSVS 6 use Win Forms? 2.This is more of a secondary question to number 1). Could controls be written in C# then; built into an assembly; be used by an app compiled in MSVS 6? 3.If you answer yes to either question; is there any documentation?
