sql server 2000 的 bigint 型的字段绑定到 CRecorderset 怎么读不出数值啊？

绑定结果是CString 型的但是读不出数据，我将其硬性的改为long型的，结果一运行就出现错误。帮帮忙，是怎么回事呀？

绑定有误：
class CXXXRs: public CADORecordBinding
{

BEGIN_ADO_BINDING(CXXXRs)
#ifdef UNICODE//用双字符
ADO_VARIABLE_LENGTH_ENTRY2(1, adWChar,m_str_Name,
sizeof(m_str_Name),m_ul_NameStatus, TRUE)
ADO_VARIABLE_LENGTH_ENTRY2(2, adWChar, m_str_Password, ////////////////
sizeof(m_str_Password), m_ul_PasswordStatus, TRUE)

#else//用ANSI字符
ADO_VARIABLE_LENGTH_ENTRY2(1, adChar,m_str_Name,
sizeof(m_str_Name),m_ul_NameStatus, TRUE)
ADO_VARIABLE_LENGTH_ENTRY2(2, adChar, m_str_Password, ////////////////
sizeof(m_str_Password), m_ul_PasswordStatus, TRUE)

#endif

END_ADO_BINDING()
public:
TCHAR m_str_Name[50;
TCHAR m_str_Password[50;

ULONG m_ul_NameStatus;
ULONG m_ul_PasswordStatus;
};
可能问题有两个：1。绑定是单双字节2。绑定后变量定义
