往列表中push_back出现错误

wow_allpoint *point_tag = new wow_allpoint();
memset(point_tag,0x0,sizeof(wow_allpoint));
wow_alllist.push_back(point_tag);

错误提示:
error C2228: left of '.push_back' must have class/struct/union

前提:
#include <vector>
using namespace std;

struct wow_allpoint
{
wsConnection *all_ws;
xyzf *all_point;
};

vector<wow_allpoint*>wow_alllist;

请高手指点

[解决办法]
还没有定义wow_alllist
wow_alllist在哪儿定义的？
[解决办法]
可能是比较老的编译器吧。
typedef struct wow_allpoint
{
wsConnection *all_ws;
xyzf *all_point;
}wow_allpoint;

试试？

[解决办法]
我没找到那2个类型，用int代替了，在vc6上编译没问题

C/C++ code

#include <vector> using namespace std; struct wow_allpoint {     int *all_ws;     int *all_point; };vector <wow_allpoint*> wow_alllist; int main(){    wow_allpoint *point_tag = new wow_allpoint();     memset(point_tag,0x0,sizeof(wow_allpoint));     wow_alllist.push_back(point_tag);    return 0;}
[解决办法]
是不是
struct wow_allpoint  
{  
wsConnection *all_ws;  
xyzf        *all_point;  
};  

里面的all_ws 、all_point没有分配内存造成的

还有，容器中包含指针，极容易造成内存泄露， 最好自己写一个类来管理内存
