说一下错误的详细信息，包括触发条件等，如果知道错误的大概地方贴出些代码更好，这些调试时候的状态信息看不出是什么错误。

首先感谢楼上的回答!

[hdmxch]

定义了一个public class lkmap类!
然后在public class maincanvas类中创建了个对象
private lkmap map;
map=new lkmap();

就这两句去掉就不会出现错误!

[Maxying]

你跟踪一下，这个类的构造函数有错吗？继续执行，看看是哪里出的错，你这个类是读取地图？还有什么其他的处理？比如响应按键？

[hdmxch]

只是读取地图!地图是个数组好象是读取时指针的错误!WTK运行出问题!

不知道这个mc是什么？会不会在某种情况下mc大于8呢？如果大于8恐怕就会ALERT: Invalid heap pointer found，请仔细检查程序的其它部分。

[Maxying]

你程序中这个函数：
public int getmcbyche(int cheid){
int x=0;
int flag=0;
for(x=0;x<9;x++){
if(lk[x][0]==cheid){
//break;
flag=x+1;
}
}
return flag;
}
当cheid在x=8的时候满足，这样flag就是9了，这样后面的操作会出现数组越界，你仔细看看你的程序，flag = x+1;没做任何边界处理。
