求个用c/c++编写windows程序源代码
期末考试用，，100行左右的代码就可以

Answer 1

下面是完整程序，MS VC++ 6.0 编译器。
主要用途，用鼠标点击调节 RGB 数值，椭圆里显示 对应的颜色。
程序里有多余的码，你可以删去。（一个多余是试验鼠标移动时连续显示坐标数值，还有一个多余部分是调用Vfw32.lib播放一个avi视频。）

Answer 2

mfc的图形界面，还是控制台的呢？具体功能是什么啊

追问

mfc的，，，功能最好是小游戏之类的，，

Answer 3

Qt写的要么？

追问

能用VS2010之类的软件编译运行吗？

追答

直接编译肯定不行
