新建空白 Access 數(shù)據(jù)庫 (.mdb) 文件,
´并添加若干類型鏈接表:
´dBase 5 (*.dbf)、
´Microsoft Excel (*.xls)、
´Microsoft Access (*.mdb;*.mda;*.mde) 等,
´然后再編寫如下 VB6 程序:
´Delphi、VC 等程序同理也可:
´引用 Microsoft ActiveX Data Objects 2.x Library
´引用 Microsoft ADO Ext. 2.x for DDL and Security
´控件: Form1、Command1、Command2、Command3
