MFC中使用控制台输出Debug信息

1. 改变整个控制台的颜色

用 system("color 0A");

其中color后面的0是背景色代号，A是前景色代号。各颜色代码如下：

0=黑色

1=蓝色

2=绿色

3=湖蓝色

4=红色

5=紫色

6=黄色

7=白色

8=灰色

9=淡蓝色

A=淡绿色

B=淡浅绿色

C=淡红色

D=淡紫色

E=淡黄色

F=亮白色

2. 改变下一个输出或者输入字体和背景的颜色

采用SetConsoleTextAttribute函数，如

White on Black：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);

Red on Black：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_RED);

Green on Black：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_GREEN);

Yellow on Black：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_RED | FOREGROUND_GREEN);

Blue on Black：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_BLUE);

Magenta on Black：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_RED | FOREGROUND_BLUE);

Cyan on Black：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_GREEN | FOREGROUND_BLUE);

Black on Gray：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |

BACKGROUND_INTENSITY);

Black on White：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |

FOREGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE);

Red on White：

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |

FOREGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE |

FOREGROUND_RED);

等等。

需要引入头文件：

windows.h

函数原型：

BOOL SetConsoleTextAttribute( HANDLE hConsoleOutput, WORD
wAttributes );

wAttributes 的取值含义对应如下：

Attribute	Meaning
FOREGROUND_BLUE	Text color contains blue.
FOREGROUND_GREEN	Text color contains green.
FOREGROUND_RED	Text color contains red.
FOREGROUND_INTENSITY	Text color is intensified.
BACKGROUND_BLUE	Background color contains blue.
BACKGROUND_GREEN	Background color contains green.
BACKGROUND_RED	Background color contains red.
BACKGROUND_INTENSITY	Background color is intensified.
COMMON_LVB_LEADING_BYTE	Leading byte.
COMMON_LVB_TRAILING_BYTE	Trailing byte.
COMMON_LVB_GRID_HORIZONTAL	Top horizontal.
COMMON_LVB_GRID_LVERTICAL	Left vertical.
COMMON_LVB_GRID_RVERTICAL	Right vertical.
COMMON_LVB_REVERSE_VIDEO	Reverse foreground and background attributes.
COMMON_LVB_UNDERSCORE	Underscore.

案例：

在MFC中使用Console作为信息输出。

AllocConsole();

int hCrt = _open_osfhandle((long)GetStdHandle(STD_OUTPUT_HANDLE), /*_O_TEXT*/_O_APPEND);

*stdout = *(::_fdopen(hCrt, "w"));

::setvbuf(stdout, NULL, _IONBF, 0);

*stderr = *(::_fdopen(hCrt, "w"));

::setvbuf(stderr, NULL, _IONBF, 0);

//system("color 0A");

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);

fprintf_s(stdout, "Info:1234567890\n");

//system("color 01");

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |

FOREGROUND_RED);

fprintf_s(stderr, "Error:1234567890\n");

FreeConsole();
