我想在用VC++1.5编程时，new一个[512][512]的大数组，却总是不行．                   
哪位专家可以指点一下．                                                           
                                                                                 
====> frank提到：
可以用CObArrary, 不过内存就不连续了。

选用Larger and Huger模式的库编译

我用过Large模式，好象不行呀！                                                    
我用Huge模式，头文件编译时就出错了！

VC++ 1.5 毕竟是16的, 512*512 是多少？                                            
做链表好了                                                                       
否则就用VC++2.0, 全32位就不该有这问题了

        这样的做法并不十分好,要分配如此大的内存最好用全局的内存分配函数.         
        直接用指针操作,效率也会提高.

用MFC类不行吗?如CObArray

请用GlobalAllocPtr和GlobalFreePtr这一对函数，如下：                              
                                                                                 
DWORD           dwSize ;;                                                        
hpsStr  =(char huge *)GlobalAllocPtr( GMEM_MOVEABLE , dwSize ) ;                 
...                                                                              
GlobalFreePtr( hpsStr ) ;                                                        
                                                                                 
不管多大数组，都保证没有问题。
