CPtrList保存Struct！！！在线急等！！！

struct ShowCharRange{
int x;
int y;
};

//// save struct
CPtrList g_Show_CString_Range;

//init CPtrList
for(int i=1;i<3;i+=2)
{
ShowCharRange *scr;
scr = (ShowCharRange *)malloc(sizeof(ShowCharRange));
memset(scr,0,sizeof(ShowCharRange));

scr->x = i;
src->y = i+1;

g_Show_CString_Range.AddTail(src);
}
free(src);

//ShowCharRange is struct
POSITION pst = g_Show_CString_Range.GetHeadPosition();
while(pst!=NULL)        //iterator list
{               
  ShowCharRange const *showChar;
  showChar = (ShowCharRange*)malloc(sizeof(ShowCharRange));
                        memset(showChar,0,sizeof(ShowCharRange));
  showChar = (ShowCharRange*)g_Show_CString_Range.GetNext(pst);
  int x = showChar->x;
  int y = showChar->y;
  CString str;
  str.Format("x:%d,y:%d",x,y);
  // show x and y error
  //this position always show x and y equal 0
  MessageBox(str,"test",MB_OK);
}

从CPtrList中取出的x和y要么都是0，要么就是很大的负数或正数...
