Hi all,I am trying to make a simple radar screen showing AI around the aircraft. Does anyone know of a tutorial or some reference material of any kind that could help me work with the Traffic Toolbox and itrafficinfo? Like a basic example of source code to start from.I am using VC++ 2005 for this btw, the rest of the gauges are in XML though. Haven't coded gauges in C for two years so a little rusty... ;) Cheers,Thomas

Thanks Ernie!Yes I knew about the sample code in the SDK, but making it work for me is another thing... I am obviously doing something wrong. That is why I was looking for more code examples.I use VC++ 2005 Express. Having successfully compiled other gauges with this setup, I now get the following compiling errors: V:gaugesinc..incITrafficInfo.h(9) : error C2061: syntax error : identifier 'ITrafficInfo' V:gaugesinc..incITrafficInfo.h(9) : error C2059: syntax error : ';' V:gaugesinc..incITrafficInfo.h(9) : error C2059: syntax error : ':'What could be the problem here? Thanks /Thomas

Hi, I'm getting the same errors when I try to compile a gauge using trafficInfo functions and I was wondering if you ever found out how to correct it. Thanks,Eric

Where are you #define'ing itrafficinfo.h file???This is the format I use for all gauges that require itrafficinfo.h file. This is in the main .cpp file for the project:#include "..incfs9gauges.h"#include #include #define ULONG_PTR DWORD#define UNICODE#include using namespace Gdiplus;#include "MyGauge.h"#include "..incgpsprop.h"#include "..incacparams.h"#include "..incitrafficinfo.h"

Thanks Bill! I actually managed to solve the error myself since I started this topic some months ago. The header file was messed up, by me as usual. Mea culpa.My C/C++ programming skills are still very rusty, since I make everything in XML these days. So to avoid wasting everybody's time I was looking for some complete samples to get me started, e.g. printing data for the nearest 20 aircraft as strings. Unlike most people, I have some difficulties understanding the SDK...So thanks anyway, but now it's back to "C++ for morons" I guess.Cheers /ThomasProud father of the J 35J Draken for FS2004http://flightsim.bookmark.se

I have a source example for a DLL in the pipeline where I program a radar screen for use with XML and C gauges, with ITrafficInfo and GDI+. Actually my "old" RadarGauge as DLL for XML usage.Anyone interested?

Very interested Arne! Been working on the same thing as it turns out. Might save me a ton of coding.Thanks!Doug

Me too! Me too! ;o) Something like that would really save the day. Thanks /Thomas

I attached the source, the dll and a XML example. The real hindrance for uploading in the library is of course the dreaded monster named documentation.

Documentation... What's that?! :7Thanks Arne.Doug

Amazing Arne! There will be a statue of you someday I am sure. This saves us mortals some weeks of trial-and-error coding.A zillion thanks /Thomas

Arne,Thanks a lot! :7 Tom

Just tried implementing this in my (still experimental) xml radar gauge. Works like a charm. One question to Arne: the blips have a dark (1,1,1?) edge, is there any way to change that color to fit another bg? I use a vector drawn circle as bg and not a bitmap btw. /Thomas

Use a dark background, then you don't see it. Or no transparancy. It's a problem with the antialiasing and the use of RGB(0,0,0) for transparency by FS. Since the RGB(0,0,0) background is somewhat smeared out with the drawn pixels, you end with some pixels above RGB(0,0,0) and therefore darker as the normal pixels, but intransparent. So either use a dark background, or for transparent drawings remove the Antitaliasing command in the GDI-drawing.... //make all drawings antialiased// m_graphics->SetSmoothingMode(SmoothingModeAntiAlias);...I'm not sure if that helps.
