Greetings !I'm a begginer in FS and I want to know HOW I can make add-on for FS (some .DLL in subdir MODULES) with C++.Can anyone give to me URL where I can read about interfaces with MS FS and may-be some source examples.Thank you very much.Vladimir_BL

Firstly I think you're in the wrong forum. The general discussion forum is for general discussion and not development.You would get a better response in the MSFS Aircraft and Panel Design Forum http://forums.avsim.net/dcboard.php?az=show_topics&forum=122To answer your question :You can find an example module on the Squawkbox site under downloads.http://www.squawkbox.caIt's in C but you can convert it to C++ very easily.To get your module to appear in the FS menu you need to hook into some of the Windows messages. Download the Platform SDK from Microsoft and read all about the Win32 API.That should keep you busy for a couple of weeks if you're a n00b to the win32 API. ;)RegardsPaul

This is really helps me alot.
