说明：  本教程举例说明了如何使用 ADO 编程模型对数据源进行查询及更新。教程首先讲述了完成此项任务的必要步骤，然后分别通过 Microsoft Visual Basic、以 VC++ Extensions 为特征的 Microsoft Visual C++、Microsoft Visual Basic、Scripting Edition 和以 ADO for Windows Foundation Classes (ADO/WFC) 为特征的 Microsoft Visual J++ 进行更为具体的说明。
(This tutorial illustrates how to use the ADO programming model for the data source query and update. First Tutorial about the completion of the tasks necessary steps, and then through the Microsoft Visual Basic, to VC++ Extensions characterized Microsoft Visual C++, Microsoft Visual Basic, Scripting Edition and ADO for Windows Foundation Classes (ADO/WFC) for the characteristics of Microsoft Visual J++ more specific.)
