Delete contents #37

Closed ADJ7WTB closed 1 year ago

Very weird problem. I added setings in the data file. Upload the code but reads nothing from the file. Open file on PC and the content is missing. Some how the data gets deleted.

The IniFile object can (and should) be created with the file mode set to read. That will prevent IniFile from writing to the file.

Thanks. Problem is that is cleared the file completely.

IniFile only requires read so set the mode to read. Opening an existing file with write mode (not append) will truncate the file.
