I am working on a software which has developed for long time. It is a Singe Document based MFC application. Now, we have a custom project which require everything with some additional features. These feature my boss don't want in a normal software and he wants to create another copy of the software. My question would be what is the best way to do this? I know copy and paste is the easiest way but not the best way. Also, I can use the inheritance but if I inherit my software Dialog class will all the controls comes in to the child dialog class too?
Thanks for the help!!!
