主界面上有icon，点击icon后建立一个frame，然后这个frame上有两个控件，一个 ok button和一个multipage，multipage中有三个页面，问题是如何关闭frame回到主界面？
原本想按ok button关闭frame回到主界面？但在vs仿真执行就出现dereference free block in GUI_ALLC_h2p()错误，求解？
贴出回调函数代码，大家帮忙看看，谢谢：
这个是multipage的第一个页面的回调函数，这个页面就是一个button，想按这个button销毁frame回到主界面上，但是不行
static void _cbDialog_Page1(WM_MESSAGE * pMsg) {
  WM_HWIN hItem;
  WM_HWIN hItem2;
  int    NCode;
  int    Id;
  WM_MESSAGE msg;
  // USER START (Optionally insert additional variables)
  // USER END

  switch (pMsg->MsgId) {
  case WM_INIT_DIALOG:
hItem = WM_GetDialogItem(pMsg->hWin, GUI_ID_BUTTON0);
BUTTON_SetSkin(hItem, _DrawSkin_Button);

// USER START (Optionally insert additional code for further widget initialization)
// USER END
break;
  case WM_NOTIFY_PARENT:
Id = WM_GetId(pMsg->hWinSrc);
NCode = pMsg->Data.v;
switch(Id) {
case GUI_ID_BUTTON0: // Notifications sent by 'Checkbox'
   switch(pMsg->Data.v) {
   case WM_NOTIFICATION_CLICKED:
      // USER START (Optionally insert code for reacting on notification message)
      // USER END
      break;
   case WM_NOTIFICATION_RELEASED:
      // USER START (Optionally insert code for reacting on notification message)
      // USER END
      #if 0
            hItem = WM_GetParent(pMsg->hWin);
      hItem2 = WM_GetParent(hItem );
      hItem = MULTIPAGE_GetWindow(hItem2,0);
      WM_DeleteWindow(hItem);
      hItem = MULTIPAGE_GetWindow(hItem2,1);
      WM_DeleteWindow(hItem);
      hItem = MULTIPAGE_GetWindow(hItem2,2);
      WM_DeleteWindow(hItem);
      GUI_EndDialog(hItem2, 0);
      #endif
      hItem = (WM_GetParent(WM_GetParent(pMsg->hWin)));
      hItem2 = WM_GetParent(hItem );
      WM_DeleteWindow(hItem);
      //GUI_EndDialog(hItem2, 0);
      msg.MsgId = WM_DELETE;
      WM_SendMessage(hItem2,&msg);
      break;
   case WM_NOTIFICATION_VALUE_CHANGED:
      // USER START (Optionally insert code for reacting on notification message)
      // USER END

      break;
   // USER START (Optionally insert additional code for further notification handling)
   // USER END
   }
   break;
// USER START (Optionally insert additional code for further Ids)
// USER END
}
break;
  // USER START (Optionally insert additional message handling)
  // USER END
  default:
WM_DefaultProc(pMsg);
break;
  }
}

这个是frame的回调函数，frame中有个button，想按这个button销毁frame回到主界面也是不行。求解啊
