将ASP代码移植为VB COM组件-4

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
