this might sound like a dumb question but im not sure how to accomplish this. I have a client that wants me to put certain buttons and menus at the top of applications they have purchased. No source code or development tools of it, but he insists it has been done before. I dont know of any ways to add anything to existing executable applications without having any type of documentation from the developer. Can anyone tell me if my understanding is correct, and if i would have to get some sort of documentation from the developer in order to build off of their application. They are .NET applications.
