I am confused. I don't know about panel and gauge design and also C++. 

I looked up almost every thing about change some special designed panel switch  and get developer designed gauge values via C#. 

ddawson (thanks a lot) made some .dll for get and set some (L:vars) I try to use them in my C# app but I could't import them into the my C# project.

My stuation :

1. I am using prof licensed P3D v4.

2. I am using C# application(VS2019) to get and set some variable from aircraft via simconnect that everything is ok.

3. I have a helicopter add-on that was created "Cera Sim" and some special panels and switches and gauges. (example:   (L:Swbatt, bool) ,  (L:Swfpapu, enum) ,  (L:Start_Eng2, bool), (>K:PROP_PITCH2_LO), etc.).

The question that:

1.How can I change the position of the switches via my C# app?

2. How can I get the special gauge values to my app?

3. Are the anyone to have any C# project to make which I want. 

4. Is there any way the control them with joystick buttons or keyboard?

Thank you

I suggest that you go to https://www.fsdeveloper.com/forum/

ask the questions you have there or search in the forums there

Yes. But C# managed code alone won't do. An external app cannot access LVars. You need a second module, a C++ DLL, that is loaded in the simulator. An internal DLL can read and write LVars, so all you have to do is to make one, and then make your C# app communicate with it (for example using a shared data area in SimConnect).

Or you use FSUIPC (which is exactly that DLL inside the sim) and find a way to communicate with it from a C# app.

Thank you for your reply. Lorby_SI do you have a .dll that made from C++ for use C#? 

vv1918 I have already asked there. Thankyou.

I do - but are you willing to pay for that? These modules are not generic, I make custom ones for every app where I need that functionality. Is it for a freeware or payware project?

You should be able to make your own. The "Mixed Mode Sample" from the panels SDK shows you how to access LVars using C++. You just have to customize it and add the SimConnect shared data area on both ends (in the DLL and in your C# code). I remember an example for SimConnect integration into the DLL from the FSX SDK, I think that it was the GDI+ example gauge. Not sure if there is sample code in the current P3D SDK.

But - I also thought that the "classic" solution is by implementing some sort of FSUIPC wrapper. Or use LUA scripts? Or both? But I know nothing whatsoever about either of those.

Best regards
