DAOTable--DAO Database, TableDef, and QueryDef Creation ----------------------------------------------------------------------- The information in this article applies to: - The Microsoft Foundation Classes (MFC), included with: - Microsoft Visual C++, 32-bit Edition, version 4.0 ----------------------------------------------------------------------- SUMMARY ======= The DAOTable sample demonstrates using the MFC DAO classes to create common database objects: Databases, Tables, Queries, Fields, and Indexes. This dialog-based application maps the properties of these objects to controls the user can set and/or view. The program source code is organized so that most database interaction is isolated from the user interface code to ease finding examples of how to use MFC DAO. In addition to demonstrating the use of the MFC DAO classes, this sample can be a useful tool for creating simple Access databases. You can create MDB files from scratch, create and delete tables and queries, add and delete fields and indexes in the tables, and modify existing queries. The following files contain the code which performs the database operations. Additional files in the project provide the user interface and high level database manipulation. QUERYDEF.CPP, .H -- functions to create and use queries TABLEDEF.CPP, .H -- functions to create and use tables FIELD.CPP, .H -- functions to create and use fields INDEX.CPP, .H -- functions to create and use indexes DATABASE.CPP, .H -- functions to create and use databases To use this code and the MFC DAO classes you must have version 4.0 or greater of Visual C++. To get the code for this sample, download DAOTBL.EXE, a self- extracting file, from the Microsoft Software Library (MSL) on the following services: NOTE: The file must be decompressed by typing "DAOTBL.EXE -d". - CompuServe GO MSL Search for DAOTBL.EXE Display results and download - Microsoft Download Service (MSDL) Dial (206) 936-6735 to connect to MSDL Download DAOTBL.EXE - Internet (anonymous FTP) ftp ftp.microsoft.com Change to the SOFTLIB\MSLFILES directory Get DAOTBL.EXE MORE INFORMATION ================ The MFC DAO classes provide a means of directly using the Jet Database Engine. While Visual C++'s wizards automatically generate code that will create and open recordsets for you based on implicitly created database and workspace objects, the code they provide does not demonstrate creating and manipulating MFC DAO objects directly. With MFC DAO classes you can create the majority of DAO objects and set their properties. This sample demonstrates using the MFC DAO classes to create and use the following DAO objects: Databases, Tables, Queries, Fields, and Indexes. Exception handling with both MFC exception macros and the C++ exception mechanism is also shown. Further, DAO exceptions are put to use in detecting the existence of objects in the DAO collections. Listed below are all the files in the project (except those which are common to all Visual C++ projects). Each file is shown with the type of components it contains and a brief description ADDQYDLG.CPP - USER INTERFACE - query definition dialog ADDQYDLG.H DAOTABLE.CPP - APPLICATION - main application objects DAOTABLE.H DAOTDLG.CPP - USER INTERFACE - main dialog DAOTDLG.H DATABASE.CPP - MFC DAO - database specific functions DATABASE.H (also demonstrates C++ exception handling) ADDIXDLG.CPP - USER INTERFACE - add indexes dialog ADDIXDLG.H ADDTBDLG.CPP - USER INTERFACE - table definition dialog ADDTBDLG.H FIELD.CPP - MFC DAO - field specific functions FIELD.H LISTCTRL.CPP - USER INTERFACE - derived CListCtrl class LISTCTRL.H INDEX.CPP - MFC DAO - index specific functions INDEX.H QUERYDEF.CPP - MFC DAO - querydef specific functions QUERYDEF.H TABLEDEF.CPP - MFC DAO - tabledef specific functions TABLEDEF.H ADDDBDLG.CPP - USER INTERFACE - database definition dialog ADDDBDLG.H REFERENCES ========== For more information about the MFC DAO classes, refer to the on-line help for Visual C++ 4.0. For additional documentation on DAO, refer to the help files in the DAO SDK which is provided on the VC++ 4.0 CD-ROM.
