I am trying to connect ODBC database as follows:

CDatabase m_database;
	CRecordset m_recordset; 
	CString strSQL,PlateNo;
	CString conn=(L"DRIVER=SQL Server Native Client 10.0;SERVER=.\\SQLEXPRESS;Trusted_Connection=Yes;APP=Microsoft\x00ae Visual Studio\x00ae 2010;WSID=EGGEN2;DATABASE=DB01;");
	m_database.Open(conn);
	m_recordset.m_pDatabase=&m_database;
	strSQL.Format(L"select * from NP where S.NO.=1");
	m_recordset.Open(CRecordset::forwardOnly,strSQL);
	if(m_recordset.GetRecordCount()>0)
	{
	m_recordset.GetFieldValue(L"PLATE NO",PlateNo);
	}
	m_recordset.Close();
	m_database.Close();

It gives an error "Failed to create empty document"

When i debugged it,the error i found was in the line "m_database.Open(conn);"

Pl suggest a solution
