Hi Bing ZHA,
Removing project "vs" will not harm. It's a small, stand
alone, not often used tool for extracting data from Nefis files.
We also noticed problems on compiling "vs" when using
Windows 10 and recent VisualStudio versions. It seems that Lex/Yacc
(used only for compiling "vs") is not supported anymore, or
at least in a different way. I'll discuss it internally what to do and
will propose to remove it from the solution permanently.
Regards,
Adri
