VB Quick View of table structure and table data
The younger brother often views the data in the database to view the table data. It is really troublesome to switch back and forth to use SQL plus for SQL server to have an Enterprise Manager or query analyzer to use SQL plus for oracle, so compiled a database viewer only for the MS SQL server and oracle database, using oledb to connect to the database this program for the VB program, the control libraries that use Microsoft Internet Controls and Microsoft Windows Common Controls 6.0 also reference Microsoft ActiveX Data Objects 2.5 Library.
