Hello,

I need to push user value in a ROM array to save mqtt username and password in the C code. I tried with StringInit Component but when I push a new value in "Str0", this variable is not saved when I restart the Pc App.

This function is it possible without design a txt file ?

1 - I set the box with the Str0 string.
2 - I enter a new string and save in Str0.
3 - I read the string from Str0.

It's ok, I have my new string in step 3 but the new string is lost if I restart the Pc App. I start with the string of step 1, registered in the Str0 parameter.





Thank you for your advices.

Hello.
If you want to use properties to store and load values, then you can use the Property Manager (Component Libraries > Storage > Utility).
It will crate a file for you, so all the hard work is removed.
Alternatively, if you attach your project, I can see if there is a better way of achieving desired results.

Hello Martin,

It's probably a perfect tool to save the variables in a .cfg file but have you an example or a method ? What is the good syntax to use the RegisterProperty Function ?

The config.cfg file is not wrote with a Save.




Thank you

If you attach your project, I will see what I can do with it.

I finally used the CSV Read Write Component to save and read variables in a config.cfg.
As this data content is password and username, I will encrypt the data before the save.

Thank you for your help.
