A few years back I was working as a contractor and one of the tasks I was working on required that my application be packed as a single executable file. I used a solution by a company called "Bit-Arts" that I don't believe is around anymore. They had a product called "Fusion" that would take a Visual Basic project file and compile the whole application, including dependent libraries/controls into a single compressed executable. They claimed that they translated everything into assembly language and thats how they were able to create the single executable, in place, file.
Does anyone know of a similar solution today? Like I mentioned the company, Bit-Arts, is not around today and I have yet to discover a similar solution. It would be great for use on our USB drives.
