代碼示例：

#include<string.h>

#include<stdio.h>

#include<stdlib.h>

arg[0]='\"';

arg[len]='\"';

HWNDhWnd=FindWindow(NULL,arg);//找到程序運(yùn)行窗口的句柄

HDChDC=GetDC(hWnd);//通過(guò)窗口句柄得到該窗口的設(shè)備場(chǎng)境句柄

HPENhPen,hOldPen;//畫筆

inti=0;

for(;i<500;++i)

SetPixel(hDC,10+i,10+i,0x0000ff);//用畫點(diǎn)的辦法畫一根線,最后一個(gè)參數(shù)是顏色（32位）

hPen=CreatePen(PS_SOLID,2,0x00ff00);//生成綠色畫筆

hOldPen=(HPEN)SelectObject(hDC,hPen);//把畫筆引入設(shè)備場(chǎng)境

MoveToEx(hDC,20,50,NULL);//設(shè)置畫線起點(diǎn)

LineTo(hDC,520,550);//畫到終點(diǎn)

Arc(hDC,100,100,300,300,350,500,350,500);//畫圓

SelectObject(hDC,hOldPen);

ReleaseDC(hWnd,hDC);

//下面是對(duì)比，表明它確實(shí)是控制臺(tái)程序
