如何更改代码::块中的文本颜色和控制台颜色?
我正在用 C 编写程序.我想更改控制台中的文本颜色和背景颜色.我的示例程序是 -
I am writing a program in C. I want to change the text color and background color in the console. My sample program is -
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <dos.h>
#include <dir.h>
int main(int argc,char *argv[])
{
textcolor(25);
printf("
This is dummy program for text color ");
getch();
return 0;
}
当我编译这个程序时,code::blocks 给了我一个错误 - textcolor 未定义.为什么会这样?我在 GNU GCC 编译器和 Windows Vista 中工作.如果它不起作用,textcolor 的副本是什么.就像那样,我想更改控制台的背景颜色.编译器给了我同样的错误,只是函数的名称不同.如何更改控制台和文本的颜色.请帮忙.
When I compile this program code::blocks gives me an error - textcolor not defined. Why is this so? I work in a GNU GCC compiler and Windows Vista. If it is not going to work what is the duplicate of textcolor. Like that I want to change the background color of the console. The compiler gives me the same error just the name of the function is different. How to change the color of the console and text. Please help.
即使答案是在 C++ 中,我也没关系.
I am okay even if the answer is in C++.
推荐答案
textcolor 等函数在 turbo C 和 Dev C 等旧编译器中起作用>.在今天的编译器中,这些函数不起作用.我将给出两个函数 SetColor 和 ChangeConsoleToColors.您将这些函数代码复制粘贴到您的程序中并执行以下步骤.我提供的代码在某些编译器中不起作用.
Functions like textcolor worked in old compilers like turbo C and Dev C. In today's compilers these functions would not work. I am going to give two function SetColor and ChangeConsoleToColors. You copy paste these functions code in your program and do the following steps.The code I am giving will not work in some compilers.
SetColor 的代码是 -
void SetColor(int ForgC)
{
WORD wColor;
HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_SCREEN_BUFFER_INFO csbi;
//We use csbi for the wAttributes word.
if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
{
//Mask out all but the background attribute, and add in the forgournd color
wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
SetConsoleTextAttribute(hStdOut, wColor);
}
return;
}
要使用这个函数,你需要从你的程序中调用它.例如,我正在使用您的示例程序 -
To use this function you need to call it from your program. For example I am taking your sample program -
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <dos.h>
#include <dir.h>
int main(void)
{
SetColor(4);
printf("
This text is written in Red Color
");
getch();
return 0;
}
void SetColor(int ForgC)
{
WORD wColor;
HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_SCREEN_BUFFER_INFO csbi;
//We use csbi for the wAttributes word.
if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
{
//Mask out all but the background attribute, and add in the forgournd color
wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
SetConsoleTextAttribute(hStdOut, wColor);
}
return;
}
当您运行程序时,您将获得红色的文本颜色.现在我要给你每个颜色的代码 -
When you run the program you will get the text color in RED. Now I am going to give you the code of each color -
Name | Value
|
Black | 0
Blue | 1
Green | 2
Cyan | 3
Red | 4
Magenta | 5
Brown | 6
Light Gray | 7
Dark Gray | 8
Light Blue | 9
Light Green | 10
Light Cyan | 11
Light Red | 12
Light Magenta| 13
Yellow | 14
White | 15
现在我要给出ChangeConsoleToColors的代码.代码是 -
Now I am going to give the code of ChangeConsoleToColors. The code is -
void ClearConsoleToColors(int ForgC, int BackC)
{
WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
//Get the handle to the current output buffer...
HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
//This is used to reset the carat/cursor to the top left.
COORD coord = {0, 0};
//A return value... indicating how many chars were written
// not used but we need to capture this since it will be
// written anyway (passing NULL causes an access violation).
DWORD count;
//This is a structure containing all of the console info
// it is used here to find the size of the console.
CONSOLE_SCREEN_BUFFER_INFO csbi;
//Here we will set the current color
SetConsoleTextAttribute(hStdOut, wColor);
if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
{
//This fills the buffer with a given character (in this case 32=space).
FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);
FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
//This will set our cursor position for the next print statement.
SetConsoleCursorPosition(hStdOut, coord);
}
return;
}
在此函数中,您传递两个数字.如果您想要正常颜色,只需将第一个数字设为零,将第二个数字设为颜色.我的例子是 -
In this function you pass two numbers. If you want normal colors just put the first number as zero and the second number as the color. My example is -
#include <windows.h> //header file for windows
#include <stdio.h>
void ClearConsoleToColors(int ForgC, int BackC);
int main()
{
ClearConsoleToColors(0,15);
Sleep(1000);
return 0;
}
void ClearConsoleToColors(int ForgC, int BackC)
{
WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
//Get the handle to the current output buffer...
HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
//This is used to reset the carat/cursor to the top left.
COORD coord = {0, 0};
//A return value... indicating how many chars were written
// not used but we need to capture this since it will be
// written anyway (passing NULL causes an access violation).
DWORD count;
//This is a structure containing all of the console info
// it is used here to find the size of the console.
CONSOLE_SCREEN_BUFFER_INFO csbi;
//Here we will set the current color
SetConsoleTextAttribute(hStdOut, wColor);
if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
{
//This fills the buffer with a given character (in this case 32=space).
FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);
FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
//This will set our cursor position for the next print statement.
SetConsoleCursorPosition(hStdOut, coord);
}
return;
}
在这种情况下,我将第一个数字设为 0,将第二个数字设为 15,因此控制台颜色将为白色,因为白色的代码是 15.这在 code::blocks 中对我有用.希望它也适用于您.
In this case I have put the first number as zero and the second number as 15 so the console color will be white as the code for white is 15. This is working for me in code::blocks. Hope it works for you too.
