基于C++怎么编写一个键盘提示音程序

这篇文章主要讲解了“基于C++怎么编写一个键盘提示音程序”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“基于C++怎么编写一个键盘提示音程序”吧！

准备资源

首先我们要下载鸡你太美的音频并剪辑好，然后再准备一个可爱的图片当作图标。

将准备好的资源添加到工程中。

之后不要忘记在主程序引用资源文件

#include "resource.h"

播放声音

使用PlaySound函数即可

 PlaySound((LPCTSTR)IDR_WAVE1, NULL, SND_RESOURCE | SND_SYNC);

获取键盘按键

使用GetAsyncKeyState获取键盘按键状态。为了方便使用，我使用了宏定义

#define KEY_DOWN(key_name) ((GetAsyncKeyState(key_name)& 0x8001)?1:0)
#define KEY_UP(key_name) ((GetAsyncKeyState(key_name)& 0x8001)?0:1)

然后就是获取键盘输入了

for (;;)
    {
        //鸡
        if (KEY_DOWN('J')) {
            if (hasPress[0] == false)
            {
                hasPress[0] = true;
                niganma = 1;
                thread t1(PlaySounds,0);
                t1.detach();
            }
        }
        if (KEY_UP('J'))
        {
            hasPress[0] = false;
        }
        //你
        if (KEY_DOWN('N')) {
            if (hasPress[1] == false)
            {
                hasPress[1] = true;
                if (niganma == 1)
                {
                    niganma = 2;
                }
                else
                {
                    niganma = 0;
                }
                thread t1(PlaySounds, 1);
                t1.detach();
            }
        }
        if (KEY_UP('N'))
        {
            hasPress[1] = false;
        }
        //太
        if (KEY_DOWN('T')) {
            if (hasPress[2] == false)
            {
                hasPress[2] = true;
                if (niganma == 2)
                {
                    niganma = 3;
                }
                else
                {
                    niganma = 0;
                }
                thread t1(PlaySounds, 2);
                t1.detach();
            }
        }
        if (KEY_UP('T'))
        {
            hasPress[2] = false;
        }
        //美
        if (KEY_DOWN('M')) {
            if (hasPress[3] == false)
            {
                hasPress[3] = true;
                if (niganma == 3)
                {
                    thread t1(PlaySounds, 4);
                    t1.detach();
                    niganma = 0;
                }
                else {
                    thread t1(PlaySounds, 3);
                    t1.detach();
                }
                
            }
        }
        if (KEY_UP('M'))
        {
            hasPress[3] = false;
        }
    }
