這裡主要包出一些函式去控制 Console 視窗，大多都是一邊看 MSDN 一邊去 try。但有些結果我覺得不是很好就註解掉，同時也讓我遇到了一些問題現在還沒辦法解決。下次再研究其它功能的時候，會再發另一篇出來，主要程式碼如下所示…

原始碼
/*
filename: EConsole.h
*/
#ifndef _ECONSOLE_
#define _ECONSOLE_
#include <windows.h>
// ============================================
// 函式： ConsoleTitle
// 說明： 設定 Consle 名稱
// ===========================================
void _SetConsoleTitle(const char* title)
{
        SetConsoleTitle(title);
        
}
// ============================================
// 函式： GetConsoleTitle
// 說明： 取得 Consle 名稱
// ===========================================
void _GetConsoleTitle(char* title, DWORD nSize)
{
        GetConsoleTitle(title, nSize);
}

// =============================================
// 函式： gotoxy
// 說明： 移動游標至指定位置
// ============================================
void gotoxy(int x, int  y)
{
        COORD point;
        point.X = x, point.Y = y;
        SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), point);
}
// =============================================
// 函式： getxy
// 說明： 取得目前游標位置
// ============================================

        x = csbi.dwCursorPosition.X;
        y = csbi.dwCursorPosition.Y;
}
// ============================================
// 函式： SetCursorVisible, 設定游標顯示比例
// 說明： 其實就是設定游標多肥大,百分比 1~100
// ===========================================

}
// ============================================
// 函式： Clr, 清除螢幕
// 說明： 解決使用 system(“cls”) 會有閃爍問題
//        事實上這只是把每個點都填上空白而已
// 轉載： CodeGurn
// ===========================================
