Answer 1

你选择工程类型时出错了,应该选择Win32 Application

Answer 2

project->settings->link 
project options中将subsystem对应的改为如下
/subsystem:windows

Answer 3

改链接选项
在Project中的Setting中，选Link选项，下面的文本框里把/subsystem:console改为/subsystem:windows

Answer 4

代码中加
#pragma comment(linker, "/subsystem:windows")
就不用次次改了~

Answer 5

工程类型错误
在setting中/subsystem:windows

Answer 6

如果你学VC,建议看看VC内幕,那是一本好书.
