Asp components Intermediate entry and one of the master
Junior Guide wrote seven, and certainly there are still some things need to write the primary, I will gradually be supplemented
Intermediate Course contents:
This may also be the greatest concern of all: such as: the operation of the database and packaging. Asp the use of built-in object. I will spend part of the longer length to show that this part of the contents of need you can more skilled use ADO database and the asp operation of the five major targets are more familiar with.
We look at the spread of the Internet compared some of the information:
As we all know, the ASP-Response, Request, Server, Session, Application five targets, five built-in fact, this is precisely target IIS console ActiveX DLL initialization of the five components that can be initialized five IIS ASP component for the course, we can direct our ActiveX DLL in the application of these components to achieve our programming, in other words, we can VB applications through the use of these components to achieve visit within ASP Purchase object function.
As long as you have a PWS4 or IIS4 above WEB server, you should have a title called "Microsoft Active Server Pages Object" for the object, we can ActiveX DLL in the VB application of the use of this object, through the use of this object, We acquired an object (): ScriptingContext, this object is precisely our entire article on the core object. The relationship between the stored object as follows:
Members of the class of objects
ASPTypeLibrary ScriptingContext Application
Request
Response
Session
Server
Through the above diagram, we can easily understand ScriptingContent category.
Below we look at a specific example:
Open vb6, Activex Dll new projects. Works were revised to fCom, class name was revised to fZ1
Quote "Microsoft Active Server Pages Object" object library.
The creation of two components events: OnStartPage and OnEndPage
OnStartPage the incident created a category ScriptingContent invoked.
Examples of the type ScriptingContent.
Code as follows:
Option Explicit
'Object statement
Dim myResponse As Response
Dim myRequest As Request
Dim myApplication As Application
Dim myServer As Server
Dim mySession As Session
'When the component is created when this incident will trigger
Public Sub OnStartPage (myScriptingContent As ScriptingContext)
'To the object instantiation
Set myResponse = myScriptingContent.Response
Set myRequest = myScriptingContent.Request
Set myServer = myScriptingContent.Server
Set myApplication = myScriptingContent.Application
Set mySession = myScriptingContent.Session
MyResponse.Write "ActiveX DLL component has been created!"
End Sub
'When the components were destroyed when this incident triggered
Public Sub OnEndPage ()
MyResponse.Write "ActiveX DLL components have been destroyed."
'Destruction of target
Set myResponse = Nothing
Set myRequest = Nothing
Set myServer = Nothing
Set myApplication = Nothing
Set mySession = Nothing
End Sub
'Definition of a component of our own way
Public Sub HelloWorld ()
MyResponse.Write "This is the built-in object used to write asp"
End Sub
Test
Open visual interdev6.0, generate a document asp
<% @ Language VBScript% =>
<HTML>
<BODY>
<%
Set obj = server.CreateObject ( "fCom.fZ1")
Call obj.HelloWorld ()
%>
</ BODY>
</ HTML>
Configured virtual directory, ie asp in the implementation of this document are as follows:
ActiveX DLL component has been created! This is the built-in object used to write the asp ActiveX DLL components have already been destroyed!
