Hi
Yesterday, I upgraded the vMicro IDE for VS2022 to version 2023.731.2200.
Subsequently I clicked a button "upgrade to the new intellisense" (I think, because the button disappeared after having clicked it and was replaced by a settings symbol).
Also since yesterday, the header file of my Arduino project is grayed out completely, starting right after the #ifndef statement. I believe this is the result of this upgrade and / or upgrading to the new intellisense.
My project compiles without any issues, but it's very confusing.
Is there a fix for that ? 

I'm working with MS 2011, VS 2022 community version 17.6.5 (up to date) and writing software for an Arduino Nano 33 IoT.

Many thanks in advance
Best regards

Hi
Per your request, this is the structure of my header file:

#ifndef _JUSTINA_h
#define _JUSTINA_h

#include "Arduino.h"
#include <SD.h>
#include <SPI.h>
#include <avr/dtostrf.h>

#define J_productName "Justina: JUST an INterpreter for Arduino"
#define J_legalCopyright "Copyright (C) Herwig Taveirne 2021, 2023"
#define J_productVersion "1.0.1"
#define J_buildDate "July 12, 2023"

// class definitions
// .....

#endif
 

Starting at the second line in the code I copied in, everything is grayed out.
The structure of the file itself has not been changed.

Best regards

Hi 
Your answer contained the hint leading to the solution: apparently the header file was defined twice: once in the main project folder and once in the subfolder 'src' where all my cpp files are located. Only one header file was defined as part of the project, the other was just a copy lingering around. As soon as I removed that one, the header file was shown as it should.
As mentioned, compilation itself was never impacted.
Best regards
