全屏幕窗口的創(chuàng)建實驗報告

1、實驗四實驗報告課程：全屏幕窗口的創(chuàng)建班級：2010級遠程教育班專業(yè)：教育技術(shù)學（遠程教育方向）實驗人：XXX學號：實驗時間：實驗室：數(shù)字媒體實驗室指導老師：XXX一、實驗?zāi)康?.熟悉窗口基本創(chuàng)建；2.學會對窗口模式改為全屏模式；3.熟悉全屏窗口的創(chuàng)建；二、實驗任務(wù)1.創(chuàng)建全屏窗口模式；3、 實驗過程1. 源代碼為：#include #include #include / define the screen resolution(定義屏幕分辨率)#define SCREEN_WIDTH 800#define SCREEN_HEIGHT 600/ include the Direct3D Libr
