# Pragma warning (Disable: 4507 34; once: 4385; error: 164)
It is equivalent:
# Pragma warning (Disable: 4507 34) // do not display the 4507 and 34 Warnings
# Pragma warning (once: 4385) // only one warning message is reported once
# Pragma warning (error: 164) // the error message 164 is used as an error.

//.......
# Pragma warning (POP)
