在ASP+中访问数据库

In an ASP+ page ,databases can be accessed by employing ADO+ objects. In order to retrieve values from
databases through ADO+ we have to follow certain procedures which are different from those employed in ADO.

The article throws Light on Various steps involved in using ADO+ in an ASP page for retrieving the
database values for an access database.

The datagrid control provided with ASP+ is used for displaying the values retrieved from the database.

First include the language in which the ASP+ page will be coded. This is specified by using Page directive
as shown below. In this example Let us use 'VB' as The language for coding ASP+ Page. The above thing can
be achieved by using the following page directive as shown below.

<%@ Page Language="VB"%>

Next Import the namespaces required for creating the Datasetcommand object and Other ADO objects such as
connection , dataset. This can be done by the following ASP+ statements

<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.ADO" %>

Next create the script required for accessing the database. In this example let us use a server side
submit control whose onClick triggers The script given below

Finally place the following HTML in the ASP+ code

<ASP:DataGrid id="dtgrid" HeaderStyle-Font-Bold="True" ToolTip="data Grid provided with ASP+"
runat="server" maintainviewstate="false" />

Thats it! The datagrid control in ASP+ page is filled up with the values retrieved from the access
database (database.mdb)
