I downloaded the NBCog.exe and was able to execute the 'NBWin32Window getFocus setWindowText: 'Hello using Native Boost' example you showed above. It looks me to like they are direct calls to the Windows API which don't require any external DLLs other the built in Windows ones..

Yes, as I wrote I just call SetWindowTextA() function from Windows API. see http://msdn.microsoft.com/en-us/library/windows/desktop/ms633546(v=vs.85).as... This one is in User32.dll which comes with Windows. Bye Torsten
