I have developed a very extensive FMS gauge for FS9 written in C. I would like to add a TCAS feature to my Nav Display. Unfortunately, the ITrafficInfo.h header is written in C++. This causes a lot of errors when I #include this header and I've been beating my head up against a wall trying to eliminate the errors. I tried to re-write the code in C++, but to no avail. Has anyone had any success using the ITrafficInfo interface? I'm using MS VC++ 5.0.Bobby Simmons

Yes, I used the ITrafficInfo interface in C++, to develop a TCAS. It works fine, but definitely wouldn't work in C. I followed the sample provided in the SDK and it went fine.Eric
