1、Windows编程实验报告题目：图形与文本专业：班级：学号：姓名：指导老师：2014年10月19日8一、实验目的熟悉MFC技术中图形和文本的使用。二、实验环境Windows7操作系统，VC++6.0三、实验内容【程序1：】编写一个单文档的应用程序,在视图窗口中显示一行文本，要求文本颜色为红色，背景色为黄色。关键代码：voidCSy2_1View::OnDraw(CDC*pDC){CSy2_1Doc*pDoc=GetDocument();ASSERT_VALID(pDoc);//TODO:adddrawcodefornative

2、datahereCStringoutstr="显示一行文本";pDC->SetBkColor(RGB(255,255,0));pDC->SetTextColor(RGB(255,0,0));pDC->TextOut(100,100,outstr);}结果截图：【程序2：】编写一个单文档的应用程序,在客户区使用不同的画笔和画刷绘制点、折线、曲线、圆角矩形、弧、扇形和多边形等几何图形。关键代码：voidCSy2_2View::OnDraw(CDC*pDC){CSy2_2Doc*pDoc=GetDocument();8ASSERT_
