VC调用存储过程出错，各位高手帮看看

try
{
//初始化数据库连接对象
m_pConnection.CreateInstance("ADODB.Connection");
//定义数据库连接字符串
_bstr_t strConn="Provider=SQLOLEDB;Server=192.168.4.185;DAATBASE=ryjk;UID=sa;PWD=123;";
//打开数据库连接
m_pConnection->Open(strConn,"","",adModeUnknown);

if (m_pConnection->State == adStateOpen)
{ MessageBox("数据库已连接上"); }
m_pRecordset=NULL;
m_pRecordset.CreateInstance("ADODB.Recordset");

_variant_t vra;
//执行SQL语句
m_pRecordset=m_pConnection->Execute("EXEC backupdata",&vra,adCmdStoredProc);
