How to extract .dll files from an installed Win 7 OS

Hi all,

I have just written some C++ app using MS visual studio compiler and fltk graphics libraries. Now the .exe file of that app works fine on my machine and I know that this is why because I have installed all the needed apps/files etc. on my machine before creating that app.
I expect that when I copy that app into another Windows machine, since it is .exe file (which is the app), it works on that else machine as well. But that else machine needs some .dll files (that I have them in my machine)

My question is that how to copy those required .dll files from my machine and save them into an else machine to make it work with that .exe file, please?

Guys, it was very easy. I went to the System32 folder from my Win 7 machine, copied the two .dll files and pasted them into System32 folder of the target machine :) The app worked!
