The problem was I was saving the files as Unicode, when the simulator wants ANSI encoding. So I made that change and everything works.

Thanks for the help Vaughan.

This is not a gauge issue. As I said, I did not even add anything to the configuration files yet. Just opening and saving the cfg files in the simulator's main SimObjects\Airplanes aircraft makes the plane unusable. Without adding anything to them.

Well, that is one thing. And I understand it. But it does not address my issue. The Baron 58 was just an example. I did the same thing with the Lockheed Martin Piper Cub. First I saved the panel.cfg into a zip file. The I opened the panel.cfg, simply used the space bar at the end of the file, and sa...

I want to edit the Beach Baron 58 panel.cfg file to change one of the gauges. If I make any change and then save the file, all of the gauges disappear on the panel. Also, if I make any edit to the aircraft.cfg file, even just using the space bar and save the file, the aircraft is no longer listed in...

I have some aircraft from FS X that work fine in Prepar3D v4 with the exception of some of the VC panel lighting. On a few aircraft there is a rectangle where none of the gauges will illuminate at night, and other areas of the VC panel illuminate fine. Just a big, dark rectangle.

Any ideas?

What sort of thing should I be looking for?

Yes, the term "Driver" is being used loosely here. It is a DLL file that is intended to load when the simulator starts, to process data used by the aircraft displays. The add-on.xml file uses category <Category>DLL</Category>. I have compiled the DLL using the Multi-threaded (/MT) runtime ...

The dll is compiled in release version. I have set the Runtime Library setting to Multi-threaded (/MT) and sent it to my testers again. Waiting for some response.

I have the driver installing into the Program Files directory structure. Could an access/permissions issue be a problem?

You are referring to the C++ Optimization and Code Generation settings?

I had them check to make sure they have the Microsoft Visual C++ 2015 Redistributable package installed. What other dependencies would effect this?

I have developed an aircraft that uses a DLL to drive many gauge display elements. I have added it on my system using the add-on.xml method. It is a DLL compiled in Visual Studio 2015. It works fine on my computer. I have sent it to several other people for testing, but the driver will not load on t...

I have a gauge (not a library) written in C++ and I want to log data to a file. I have tried _wfopen, and std::wofstream std::wofstream::eek:pen. Both crash the simulator.

Has anybody got some clues on how to write to files from a gauge?

Had a long delay in addressing this due to a death in the family. I have tried everything. I compiled the Cabin Comfort sample in 64 bit using Visual Studio 2017. I entered it into the dll.xml file using the configuration command line, as outlined in the Lockheed Martin website: "C:\FS\Prepar3D...

My understanding is that VS 2015 is required to compile gauges that use Simconnect. This gauge does not. I cannot think of any ethical reason why a company like Lockheed Martin would require one certain C++ compiler to work in the simulator. What about people who don't even use MS Visual Studio? If ...

Yes, that's me.
