请问高手：如何用键盘控制小球的运动？先谢谢了！

Question

我在CMyView::OnCreate()里设置了一个定时器SetTimer(1,200,NULL);在视类的构造函数中给小球一个初速度，使其在定时器事件里自动行驶，问如何用小键盘的四个方向键、Home（左上）、PgUp（右上）、End（左下）、PgDn（右下）这八个方向键控制小球的行驶，并且当按键时，定时器关闭；不按键时，小球按原来轨迹自动行驶？
    以下是源代码：
    CMyView::OnTimer(UINT nIDEvent)里
    {
CClientDC dc(this);
dc.Rectangle(10,10,520,450);//画边框,使小球移动范围限制在该矩形框里
CDC *mdc=new CDC;
mdc->CreateCompatibleDC(&dc);
CBitmap *bitmap=new CBitmap;//小球20*20象素即半径10象素
bitmap->LoadBitmap(IDB_BALL);//装载小球图片
mdc->SelectObject(bitmap);
dc.BitBlt(x,y,20,20,mdc,0,0,SRCCOPY);//小球初始位置(500,430)
//x,y,vx,vy是视类的成员变量int x,y,vx,vy;
//在视类的构造函数中赋初值x=500;y=430;vx=vy=5;
x += vx;//小球的初速度vx=vy=5象素
y += vy;
if(y >= 430)//小球碰到矩形底时,初速度反向
{
vy = -vy;
y = 430;
}
if(x >= 500)//矩形右边
{
vx = -vx;
x = 500;
}
if(x <= 20)//矩形左边
{
vx = -vx;
x = 20;
}
if(y <= 20)//矩形顶
{
vy = -vy;
y = 20;
}
CFormView::OnTimer(nIDEvent);
if(mdc) delete mdc;
if(bitmap) delete bitmap;
    }

Answer 1

楼主:我怎么编译不行呢
说这个CFormView::OnTimer(nIDEvent);有问题哦还请楼主指点一二

Answer 2

设一个标志，当键盘按下时执行另一个函数，而在OnTimer()里面的绘图动作停止

Answer 3

nuaawenlin(飘人):你好！能不能详细点，我是初学者，好多东西都不会。如何获取键盘对小球的控制？函数如何写？能帮我写写吗？

http://fxstudio.xiloo.com/code/snake.zip这个怎么玩呢

Answer 6

Skt32(荒城之月)谢谢指点，今天晚上我研究一下！但是我运行的时候怎么没有背景音乐啊！我仔细没看源代码！还是看了再问你吧!

重载ON_KEYDOWN消息
void CMyView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) 
{
switch(nChar)
{
case 87://大写W键的ASCII值       可以控制小球向上移动
case 119://小写w键的ASCII值
KillTimer(1);//KeyDown时关闭定时器
y += vy;
this->DrawBall(x,y);//你自己定义一个画小球的函数
if(y <= 20)//
{
vy = vy;
y = 430;
}
SetTimer(1,200,NULL);//不按键时让小球自己走
break;
         //其他的键控制可以参考上面，自己要多练习
}
