In the end we listed the source program of the technology of ASP applied in actual project for reference.鷙俗舍脂豐濱松吼觚簪趨萏選Key Words: ASP, HTML, Web Server駁洄韭帆菽

3、街黠濃蹼牽溺鐙痙ASP is Web Servers script environment, which explains script in Internet and intranet stations Web Server. It can explain and execute every request, which are sent by IE, and then responses and executes active, interactive and high efficient Web Server applied program. In construction any su

ASPS and HTML 坭結(jié)滋頌評(píng)栲紲痦雜候蛔染锍When it comes to ASP, we have to talk about another language, in which we construction Web Site need: Hyper Meta Text Language, which is short for HTML.爺看集醇鴕螃饌躥塋耳痼琳菜 HTML usually describes a

5、 pages all basic factors in text description language. All content and model shown by page to users are included in a smaller script file. Usually designers use as seen as is compliers such as FrontPage 98, Netscape Gold 3.0 and so on design a page and then upload it to Web Server. After using brows

Because users browse this page every time, they see all the same

7、things unless designer refreshes this page. At the same time, as not having interconnected operation with users. Not having interfaced with enough database resource, these web stations content is very single. Although Web applied program written in CGI technology can be changed into active web page,

8、 it can only be made with a single data operation, not having interconnection capacity. And has very high and strict request to designers. It needs making a CGI program for every acquirement, its work is very large and its Codes are not all successfully executed. When many users visit a CGI at the s

For example when we have filled in table and send HTTP request in IE, it may need Web Server executes an applied program designed by table, not a simple HTML file. This applied pro

The work principle and configuration ASP誶戛守猢鷥畚菸獺嬡歧刀羔電 In server machine, we may apply an ASP homepage; web server should responses this HTTP request and explains this applied file. When it meets any compatible script with Active X Scripting (for exam

14、ple VBScript and JavaScript), ASP can ask proper script to deal with it. If script instruction includes request of visiting database, it can connect with the behind database by ADOPB and ODBC. It may execute visiting database-by-database visited machine. ASP script is explained and executed in Web S

What we can see page in users IE is shown in single HTML, for example, content of behind database expressed in form of table. As ASP combinated with JavaScript and VBScript. it can visit ActiveX component by pr

ASP and ACTIVE X鰨揪獗髁芍憮樺觫淠舡隕竽秒When we make Web with ASP technology, we have to follow with this principle. It

27、 is that, only in cohere between ASP Server script and component object model, can we make out practical and useful information software. ASP script is a connection, can connect some component objects with some certain characteristic function objects to form finish software. This industrial principl

Reuse latter, we can abstain directly without downloading. This is what Active X is better than Java Applet.薩慘憬榪翰承蹼雩跣犖井槿儐From the far sight,

58、行動(dòng)態(tài)Web開發(fā)的時(shí)候，應(yīng)遵循這樣一個(gè)原則:即ASP的服務(wù)器端腳本必須與微軟倡導(dǎo)的組件對(duì)象(Component Object Model)配合使用才能開發(fā)出具有實(shí)用價(jià)值的信息產(chǎn)品。ASP腳本相當(dāng)于一種粘合劑，把一個(gè)個(gè)具有特定功能的組件對(duì)象粘合在一起，以形成最終的軟件產(chǎn)品。這一軟件制作的工藝思想類似于硬件工廠生產(chǎn)板卡的過程，那一個(gè)個(gè)的組件對(duì)象就相當(dāng)于集成電路的芯片，而ASP腳本只是焊接芯片的焊接劑，由此可見組件對(duì)象起著核心作用。屈藍(lán)菠伴瓤嚯標(biāo)材逃筅墩蚴紙組件對(duì)象模型COM是微軟提出的一種基于二進(jìn)制的Windows軟件標(biāo)準(zhǔn)，它是由OLE技術(shù)逐漸發(fā)展而來的。在使用不同語言工具寫成的組件對(duì)象之間，依據(jù)COM的標(biāo)準(zhǔn)可以進(jìn)行交互。COM是技術(shù)概念和標(biāo)準(zhǔn)，其商業(yè)概念的稱謂則使用Active X。楝葑縱僚半峋驕糕瞪佤坌肉坻 在WEB網(wǎng)站開發(fā)中，最重要的就是使用ADO對(duì)象訪問數(shù)據(jù)庫了。用戶在登錄網(wǎng)站以后，WEB服務(wù)器就自動(dòng)執(zhí)行數(shù)據(jù)庫服務(wù)器程序登錄的程序，然后針對(duì)用戶以后的不斷的復(fù)雜的請(qǐng)求，WEB服務(wù)器自動(dòng)解釋執(zhí)行ASP網(wǎng)頁中內(nèi)嵌的VB Script或Java Script語句，然后運(yùn)行SQL查詢，最后再將結(jié)果反饋回給用戶。叼曷
