vs2012 MFC 编译时弹出参数错误对话框，还有内存泄露

程序代码：

void CData::SearchList(CString search)
{
   

    if(search.IsEmpty())//判断是否输入搜索值
    {
        AfxMessageBox(_T("请输入搜索关键词！"));
        return;
    }

    extern CListBox *glistbox;

    int count=glistbox->GetCount(),i=0,num=0;
    CString str;
    for(int j=0;jGetText(j,str);//获取行
        &search;
        if(str.Find(search)==-1)
        {//判断是否有搜索的内容
            glistbox->DeleteString(j);
            i++;
        }
    }
    
    num=count-i;
    str.Empty();
    str.Format(_T("搜索到%d条相关信息！"), num);
    AfxMessageBox(str);
  
}

调试时会弹出参数错误对话框
