怎么改正！不胜感激

Answer 1

OnCreate\OnSize\OnDestroy三个函数不应该直接添加，他们是消息处理函数。把他们删除，然后给view类分别响应消息WM_CREATE\WM_SIZE\WM_DESTROY，在生成的这几个消息响应函数里用你的代码填充。

Answer 2

OnCreate

OnDestroy

OnSize

这3个函数需要声明

Answer 3

你再这个类的头文件中加入没有找到的那几个函数的头文件

Answer 4

消息响应函数,最好用类向导添加.手动添加的话还要修改几处

Answer 5

你是不是把那个图标拖到桌面上进行使用？？
