# Pragma warning description

1. Disable, once, error
# 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.
2. Push, pop
This pragma warning also supports the following formats:
# Pragma warning (push [, N])
# Pragma warning (POP)
Here N represents a warning level (1---4 ).
# Pragma warning (push) saves the existing warning status of all warning information.
# Pragma warning (push, n) saves the existing warning status of all warning information and sets the global warning level to n.
# Pragma warning (POP) pops up the last warning message to the stack,
All changes made between the inbound and outbound stacks are canceled. For example:
# Pragma warning (push)
# Pragma warning (Disable: 4705)
# Pragma warning (Disable: 4706)
# Pragma warning (Disable: 4707)
//.......
# Pragma warning (POP)
At the end of the Code, save all warning information (including 4707, and ).
