I am trying to get certification for some hardware integration in our application. In order to allow us to continue to modify the application without having to recertify the whole application, I want to encapsulate the functionality for integration into a separate module, such as a dll. I need to be able to include both the configuration screen and the screen that captures the data from the hardware in a separate library that I can compile and call into to display the forms. Is this possible? I don't think I can do it through a com exe because it hangs my app every time I try to display any UI elements.
