how does nsis bind files to the exe?

does nsis use visual basic or c++?
im making an installer through visual basic and dont know how to bind files to the exe so i can copy them to a location. does ammyone know?

I'm assuming c++ since the source code is in ... c++

Why build a completly new VB installer when you can use the mighty NSIS?

they are tacked on the end of the exe file. Just like the windows pe header is tacked on the end of an msdos exe. It doesn't matter to windows because the resource table is used to map the exe file to memory and the last part tacked on the end is simply not loaded.
