由于绑定操作是由宏实现的ADO EXTENTSION 绑定 recordset时需要注意冗余变量问题 不慎将导致记录无法出来 class CHasPrpRs : public CADORecordBinding { BEGIN_ADO_BINDING(CHasPrpRs) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_TenantIndividualID sizeof(m_ch_TenantIndividualID) m_ul_TenantIndividualIDStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Email sizeof(m_ch_Email) m_ul_EmailStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_TenantIDNumber sizeof(m_ch_TenantIDNumber) m_ul_TenantIDNumberStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Name sizeof( m_ch_Name) m_ul_NameStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Salutation sizeof( m_ch_Salutation ) m_ul_SalutationStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Country sizeof( m_ch_Country ) m_ul_CountryStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Phone sizeof( m_ch_Phone ) m_ul_PhoneStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_CellPhone sizeof( m_ch_CellPhone ) m_ul_CellPhoneStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Fax sizeof( m_ch_Fax ) m_ul_FaxStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_PHS sizeof( m_ch_PHS ) m_ul_PHSStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_MoveInDate sizeof( m_ch_MoveInDate ) m_ul_MoveInDateStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Company sizeof( m_ch_Company ) m_ul_CompanyStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Actived sizeof( m_ch_Actived ) m_ul_Actived true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_MemberID sizeof( m_ch_MemberID ) m_ul_MemberIDStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Language sizeof( m_ch_Language ) m_ul_LanguageStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Marriage sizeof( m_ch_Marriage ) m_ul_MarriageStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Occupation sizeof( m_ch_Occupation ) m_ul_OccupationStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_newsletter sizeof( m_ch_newsletter ) m_ul_newsletterStatus true) ADO_VARIABLE_LENGTH_ENTRY( adVarChar m_ch_Gender sizeof( m_ch_Gender ) m_ul_GenderStatus true) END_ADO_BINDING() public: //<Point A TCHAR m_ch_TenantIndividualID[]; // TCHAR m_ch_Email[]; // TCHAR m_ch_TenantIDNumber[]; // TCHAR m_ch_Name[]; // TCHAR m_ch_Salutation[]; // TCHAR m_ch_Country[]; // TCHAR m_ch_Phone[]; // TCHAR m_ch_CellPhone[]; // TCHAR m_ch_Fax[]; // TCHAR m_ch_PHS[]; // TCHAR m_ch_MoveInDate[];//datetime // TCHAR m_ch_Company[]; // TCHAR m_ch_Actived[]; // TCHAR m_ch_MemberID[]; // TCHAR m_ch_Language[]; // TCHAR m_ch_Marriage[]; // TCHAR m_ch_Occupation[]; // TCHAR m_ch_newsletter[]; // TCHAR m_ch_Gender[]; // //int m_i_TenantIndividualID; //<Point B ULONG m_ul_TenantIndividualIDStatus; // ULONG m_ul_EmailStatus; // ULONG m_ul_TenantIDNumberStatus; // ULONG m_ul_NameStatus; // ULONG m_ul_SalutationStatus; // ULONG m_ul_CountryStatus; // ULONG m_ul_PhoneStatus; // ULONG m_ul_CellPhoneStatus; // ULONG m_ul_FaxStatus; // ULONG m_ul_PHSStatus; // ULONG m_ul_MoveInDateStatus; //datetime // ULONG m_ul_CompanyStatus; // ULONG m_ul_Actived ; // ULONG m_ul_MemberIDStatus; // ULONG m_ul_LanguageStatus; // ULONG m_ul_MarriageStatus; // ULONG m_ul_OccupationStatus; // ULONG m_ul_newsletterStatus; // ULONG m_ul_GenderStatus; // public: inline void Init() { //m_i_TenantIndividualID=; memset(m_ch_TenantIndividualIDsizeof(m_ch_TenantIndividualID)); // memset(m_ch_Emailsizeof(m_ch_Email)); // memset(m_ch_TenantIDNumbersizeof(m_ch_TenantIDNumber)); // memset(m_ch_Namesizeof(m_ch_Name)); // memset(m_ch_Salutationsizeof(m_ch_Salutation)); // memset(m_ch_Countrysizeof(m_ch_Country)); // memset(m_ch_Phonesizeof(m_ch_Phone)); // memset(m_ch_CellPhonesizeof(m_ch_CellPhone)); // memset(m_ch_Faxsizeof(m_ch_Fax)); // memset(m_ch_PHSsizeof(m_ch_PHS)); // memset(m_ch_MoveInDatesizeof(m_ch_MoveInDate));//datetime // memset(m_ch_Companysizeof(m_ch_Company)); // memset(m_ch_Activedsizeof(m_ch_Actived)); // memset(m_ch_MemberIDsizeof(m_ch_MemberID)); // memset(m_ch_Languagesizeof(m_ch_Language)); // memset(m_ch_Marriagesizeof(m_ch_Marriage)); // memset(m_ch_Occupationsizeof(m_ch_Occupation)); // memset(m_ch_newslettersizeof(m_ch_newsletter)); // memset(m_ch_Gendersizeof(m_ch_Gender)); // } CHasPrpRs() { Init(); }; virtual ~CHasPrpRs() {}; };如上代码Point A与Point B之间不能出现冗余变量否则有可能导致取不到值或者无法显示 |
