本人刚接触mfc，老师要求在打开的图片上写字，找了个书上的例子，调试出错，请高手指点！！谢谢！！！没什么分了，不好意思！！

在CKeyExampleDoc定义了：
public:

CString m_strText[MAX_LINES];
int m_nCounter;



在这个地方出现错误和警告
KeyExample.cpp
error C2065: 'MAX_LINES' : undeclared identifier
error C2057: expected constant expression
error C2229: class 'CKeyExampleDoc' has an illegal zero-sized array warning C4200: nonstandard extension used : zero-sized array in struct/union

KeyExampleDoc.cpp

[开心的三三]

MAX_LINES 要 #define一下

[江川]

#define MAX_LINES 1024

class C***Class
{
public:

CString m_strText[MAX_LINES];
int m_nCounter;
}

谢谢了，感激不尽啊，运行出来了，谢谢了，想在自己打开位图上写字，这个能行吗，运行出来后，弹出来单文本后，一碰键盘就出错：说什么指令应用的内存不应该为read，不知道怎么回事？
