New project - MSFS C++ USB interface

Thanks. Yup, tried C For Dummies 20+ years ago and got nowhere fast.

I'll refer you one youtube video later. The dude speaks clearly, and in no time you have a basic window with buttons and stuff.

Best part, Visual Studio 2022 Community is free. It's way better than what we had for Visual Basic way back when.

Here, download and install VS2022 Community. It's free.

Then follow his instructions to the letter. You have a simple Windows form in no time.

Thanks for the link.

It's so frustrating. "Experts" on forums assume you know C++ nearly as much as they do, or point to sample code that is exactly like what you've already put together, or say "hey, just use this conversion routine" - except that routine doesn't work against that sort of variable.



I'm so close, I can see the data in the structure and it matches what's displayed on the instrument panel. I guess I'm off to "C++ structure tutorials" in hope of finding something useful.

Argh, it's like extracting teeth; slow and painful. Thanks to google I was able to "address" the structure element properly and copy it into a double variable.



I may have got just a tad smarter by learning this, but I just moved the problem into another pile; I can't seem to be able to do anything with a double variable. Can't display it on screen, can't convert it to a string; I tried but commented out the attempts to keep track of what I did.

WOOT!

It helps when you know what questions to ask google, AND you get very well-explained pages.



Now I have to return that value to the PIC, but in the meantime, I'm getting a beer.

EDIT: Hmmm, maybe I don't deserve that beer yet. There's a 15 second lag before throttle changes are reflected in my app. I'm hoping it's because I used "option 2" on how you can poll SimConnect for variables; it also contains the USB code (not sure yet if that can impact the SimConnect logic).

Really hoping "option 1" works as promised by the Devs (it's a callback routine, not my type of code, but hey, if it works as promised).

About 7 years ago I decided to get serious about Visual Basic (as opposed to C++) and bought 5 different books on the subject. I'm an old fart (56) and still like paper books. At any rate, about 90% of what I need to know is somewhere in at least 1 of those books. Occasionally I have to jump on YouTube for answers, but the books really helped me. Just sharing my experience.
