将ASP代码移植为VB COM组件-4
类别: ASP教程
这个例子中的第一站是ASP页。这个ASP页用ADO与Northwind 数据库连接。为了保持良好的编码习惯,我
使用了Option Explicit 并明确地声明了所有变量。这个ASP页的第一个草稿使用了内联代码。
< % @ LANGUAGE=VBScript % >

\'Example of Inline code
Option Explicit
\'Declare variables
Dim oConn
Dim oRS
Dim ConnectionString
Dim x
ConnectionString = "DSN=Northwind;"
Set oConn = Server.CreateObject("ADODB.Connection")
oConn.Open ConnectionString
Set oRS = Server.CreateObject("ADODB.Recordset")
\'Set variables
oRS.ActiveConnection = oConn
oRS.Source = "Select * from Products"
oRS.Open
