1、asp banner ad systemto the reader from joe:this is a user-submitted tutorial by the author above. i have read the tutorial and set the format to fit html goodies, but for the most part have not changed the language. i chose this tutorial because many readers have been asking for more asp tutorials.

2、this is a great one.sorry i cannot show you the event here. the html goodies servers do not offer asp. i will tell you though that if you run ie5.0 or better, open the contents of the zip file into a directory and it runs just fine.if you havent already, you may want to read my introductoryasp tutor

3、ialbefore this one. if not, then enjoy. there may be a point in your web design career, where your site becomes real popular. that is when companies become interested in advertising on your site. a banner ad system can be built to control all those advertisements that you are so willing to display,

4、for a price. active server pages makes it very easy to create a banner ad system. so easy, that the microsoft asp developers created an adrotator component for the occasion. before you begin reading this article, make sure you download the support material below.the files included aread.txtbanner.as

5、p3 banner imagesclicks.aspexample.aspredirect.aspad.txtin order for the adrotator component to work, you must configure a text file. this text file contains all the banner ad properties. however, the text file must follow a certain format. the first four lines are as follows：redirect redirect.aspwid

6、th 400height 50*redirectwhen a banner is clicked, the adrotator component goes to a preliminary page. this page is called a redirect page. the redirect page handles any extra programming events before directing a user to the banners destination. in this example banner system, i called the preliminar

7、y file redirect.asp.widththis sets the width of the banner ad image. the value must be in pixels.heightthis sets the height of the banner ad image. the value must be in pixels.*the asterisk tells the adrotator component that it is about to acquire banner ad information. the asterisk is required.once

8、 you define the general properties above the asterisk, then comes the list of banners to display. in thead.txtfile, there are three banners defined below the asterisk.banner1.jpghtmlg20banner2.jpgy30banner3.jpgd30each banner requires four lines of properties, which follow the format below：image file

9、nameweb address descriptionbanner weightimage filethe image filename can be a fully qualified web address or relative name that points to the image. if the image is in a different folder, then you also include the folder name as well.( banner1.jpg, or foldername/banner.jpg)web addressthe web address

10、 can be a page on your site or a fully qualified web address that leads to another site.descriptionthe description will be displayed as a tool tip. when you rest your mouse over the banner, the description pops up.banner weightthe banner weight determines how much a banner is displayed. the adrotato

11、r component adds all of the banner weights and determines the probability or percent chance of a particular banner being displayed. a banner with a higher weight has better a better probability.note:you can disable a banners property by substituting with a dash.banner3.jpg-d30the example entry above

12、 would create a banner ad that does not have a web address.banner.aspthis file uses the adrotator component and analyzes the contents of the ad.txt file. below is the code.sub banner(strtarget)dim bannerad, htmlset bannerad = server.createobject(mswc.adrotator)bannerad.targetframe = strtargethtml =

13、bannerad.getadvertisement(ad.txt)response.write htmlend subthe first thing to note is that the asp was written with vbscript. the second thing to note is that the code is written inside a sub procedure calledbanner(strtarget).for those of you who do not know, a sub procedure allows you to group toge

14、ther a bunch of code that can be reused over and over. like a function, it takes an argument, such as a word or variable. in the code above the argument is strtarget.unlike a function, a sub-procedure does not return any values, it just executes the code inside line by line.inside the sub i declare

15、two variables.dim bannerad, htmlnext i store the adrotator component inside the bannerad variable. when storing a component inside a variable you use the set keyword. since we are programming server-side with asp, we use server.createobject to summon the component. mswc.adrotator is the component ke

16、y or name value.set bannerad = server.createobject(mswc.adrotator)next i use a property of the adrotator called targetframe. this property is equivalent to：the target-value can be one of the values below：_blankopens the destination link in a new browser window._topopens the destination link on top o

17、f the web page._parentopens the destination link within a parent frame._newopens the destination link in a new browser window.next, i use an adrotator method or function called getadvertisement and stored its results in the html variable. notice that the getadvertisement takes the name of the ad ban

18、ner text file as an argument.html = bannerad.getadvertisement(ad.txt)finally, i want to print the contents of the html variable. this prints the code that displays the banner images.response.write htmlredirect.aspthis is the file that is processed before someone is redirected to the banners web addr

19、ess. inside this file, we can capture information like how many times a particular banner is clicked and so on. to start things off, i defined a variable called strurl.dim strurlnext i store a querystring value inside this new variable.strurl = request.querystring(url)a querystring is nothing more t

20、han a bunch of name/value pairs attached to a web address. when a user clicks on a banner, the adrotator component attaches a querystring to the redirect file. so if we were to click banner1.jpg, defined in ad.txt, we would end up with a redirect web address that looks like so.redirect.asp?url=&imag

21、e=banner1.jpgin essence assigning request.querystring(url) to strurl, is the same as assigning to it.finally, i check to see which banner was clicked. i accomplish this with the vbscript instr( ) function.if instr(strurl, htmlgoodies) then application.lockapplication(htmlgoodies) = application(htmlg

22、oodies) + 1application.unlockresponse.clearresponse.redirect strurlend ifthe instr( ) function returns the number position of a sub-word (sub-string) within another word (string). the format is as followsinstr(main word, sub-word)if the sub-word exist within the main word, then the function will equ

23、al a number greater-than zero or true. if the sub-word does not exist, then the function will equal zero or false. in the example above, i check to see if htmlgoodies exist within . since the answer is true, then the code inside the if. then. statement will execute.inside the if. then. i use an appl

24、ication variable. an application variable is native to asp. application variables store information as long as a web application exist, a web application ceases to exist when say someone shuts off the web hosting server. the beauty of an application variable is that you can define it on one web page

25、 and use it in other web pages within your web application. the downfall is that the users computer must have cookies enabled.anyways, the code adds one to the application variable, every time a banner is clicked. after one is added, the code redirects to the banners web page. so if banner1 was clic

26、ked then you shall be redirected to .response.redirect strurlexample.aspthis is an example page that uses the banner ad system. when you refresh the page, you should most likely see a different banner. whenever you want to insert the banner ad on a page, you can use the ssi directive below.once you

27、include the file above, then you can call the sub-procedure inside the banner.asp file like so.call banner(_blank)notice that i supply one of the values for the targetframe as an argument. so if the banner is clicked, then the web page should open up in a separate browser window.clicks.aspthis is a

28、very simple page that displays the number of clicks per banner ad. to display the number of times a banner was clicked, you just print the contents of the application variables that were created inside redirect.asp. pretty nifty.asp橫幅廣告系統(tǒng)喬給讀者的話：這是一個(gè)由用戶提交上述筆者的教程。我已經(jīng)閱讀教程和設(shè)置格式，以適應(yīng)的html超值，但大部分都沒(méi)有改變的語(yǔ)言。我
