Apr 8 2001 ____________________________________________________________               C o v e r Y o u r A S P . c o m              Welcome to the latest newsletter!                  http://CoverYourASP.com/ ____________________________________________________________ Normal service will now resume! I've had a nice vacation, read and/or answered the 600 emails waiting for me, and now it's time for this, my last item of the to-do list. Then I can do some work! ____________________________________________________________         A   W O R D   F R O M   M Y   S P O N S O R S                 http://www.nsoftware.com/ ____________________________________________________________ IP*Works!

I had an excellent time, but response time may still be a little slow to your emails - I have over 600 to sift through... ;-) ______ 7 Apr ______ - Thanks to the anonymous user who pointed out that the link to the source code of utils/database.asp was broken on the Server Side Includes page. http://CoverYourASP.com/SSI.asp That's now fixed, and I now get emails when similar things happen - my ShowSource.asp page doesn't show files that don't appear in its switch statement just to give me the option of hiding some files on my site! ____________________________________________________________          A   W O R D   F R O M   M Y   S P O N S O R S                 http://www.developersdex.com ____________________________________________________________ Developersdex delivers the world's largest index for Microsoft web technologies.  Search, post, and reply to over 20 of the most popular ASP, SQL, VB and XML Usenet newsgroups. Devdex indexes over 5,000 new resources everyday including those from MSDN, ASP.NET, 15seconds, 4guysfromrolla, ASPToday, XML and ActionJackson.com just to name a few.

This will allow you to see the source for particular files without downloading the whole source code. You could always copy/paste the code into a new file if you wanted to get the updates! http://CoverYourASP.com/SSI.asp ____________________________________________________________               H E R O   O F   T H E   W E E K ! ____________________________________________________________ Since I've been on vacation, I haven't prepared anything or been able to get a decent biography from a real hero, so I'll take the easy route (no change there) and nominate my wife Tara. http://ShawThing.com/images/BenchTwo.jpg She's sitting in the room with our 20 month old son Jesse fast asleep on her lap, knowing that she can't talk to me (well, she can, but she knows she only gets grunts back). I sit in front of this beige box quite a lot as you can imagine (try every minute that I'm not doing odd-jobs), but strangely I don't get any grief for it. I think it's because she's amazed that one of my hair-brained ideas actually became successful. I've had quite a few attempts at doing something (anything?) from selling craft-fare trinkets mail order (I sold 11) to investing in rare coins (he was a conman) to spending 12 months with 3 partners writing a huge web site that never got launched, and now sits on my "maybe-next-year" list. I should have asked previous heroes, but I wonder if that's a common theme - behind every successful web site there's a very, *very* patient wife... ;-) ____________________________________________________________                N E E D   A N   A S P   I S P ?         Use mine.

I copied the ASP pages and changed their extensions to .txt expecting that when I linked to these files notepad, or some other application, would open up and display their contents. This does not happen." Me: That's what is supposed to happen I'm afraid. A browser cannot open another application for security reasons. You obviously see the text file inside the browser, but Notepad won't be used. ______ Desmond: "I got most of the search working while you were away. Funny thing though I had to put a space in front of the fields in the database and then the search worked. Hmmmm. Any way the only part I have not figured out is how to print a group heading for the fields. Welcome back. Hope you and your family enjoyed the time away." Me: We had a great time thanks. I do a word search, hence I search for space followed by the word you search for. So you need a space at the front of each field, exactly as you found, or the first word in the field won't ever be found. ______ Paul P-W: "Your site looks great - I'm just getting into this ASP game & was in need of some friendly advice, so thanks! :>) Here is a problem that you *might* not be aware of, might have a fix for & also may want to refer to on your site: I have installed PWS (from a Win98 CD) onto my laptop which came with WinME (it is not included with WinME - see Microsoft knowledge base Q266456). It installed okay (apart from a problem with MTS, documented in Microsoft knowledge base Q246081). PWM then seemed to run okay, but I could not get Frontpage2000 to publish to my PWS directory - it gave an error and suggested I try ftp instead. I also could not run the server extension manager that installed with PWS - it told me there was a more recent version of the server extensions on my PC. I have downloaded the Windows NT 4.0 Option Pack which has another version of PWS, so I will try that next. Thanks for your time." Me: Thanks Paul! I knew about the first two issues, but not about FP. FP is of course the devils spawn - see http://coveryourasp.com/Search.asp?frontpage ______ Indira Bhat: "What is the best way to walk through the folders recursively and list them ORDER BY LAST MODIFIED DATE?" Me: Store the file dates in an array, like I store the names in an array in http://CoverYourASP.com/ArchivesDescr.asp, and then sort the array afterwards. Using my code as a basis, the oFile object has a property that you can query to get the date - oFile.DateLastModified. ______ David Davtian: "Hi James, first of all great-great website, I've learned a lot from your work and I'm glad that there are people like you in this world. So I have an ASP driven membership website and I'm running an SQL server for the back end, and I'm trying to find a script that will show which member is online, perhaps showing a list with all members and those folks who are connected to the server, a red star or something next to their name and those offline will have no star. Do you know where I can start?..where/what I can research?" Me: I've been asked that a few times, but I've never needed it myself. Maybe in the future when I have a real members area or forum it'll be useful. I'd suggest setting the members status to "online" by adding code to update the database in utils/login.asp, ValidateLogin, just below where the session variables are set up. See http://CoverYourASP.com/ShowSource.asp?page=utils/Login To keep note of logged out users, update the database in global.asa's Session_OnEnd. ______ Kurt Meyers: "I use to have something in VBScript that took a 9 digit SSN and split it so I could put in the '-''s. But after looking at your code I have grown fond of JScript. I was just wondering how can I do that in JScript? Here is what is looked like in VBScript : Left(SSN,3) & " - " & Mid(SSN,4,2) & " - " & Right(SSN,4) Any help would be greatly helpful" Me: JavaScript's string object has a slice method (amongst many other useful ones) but no left/mid/right- but see http://msdn.microsoft.com/scripting/jscript/doc/jsobjstring.htm ______ Carl Revell: "Just a simple one, I found that by doing a refresh on the SurveyResults page I was able to increment the option I'd voted for with every page refresh. I noticed the code uses a Cookie to prevent this and I have cookies enabled but was still able to increment the count. I refreshed 3 times if you want to reduce the value for an accurate count! http://CoverYourASP.com/SearchSurvey.asp Me: Thanks! If you look closely, you'll see that I set the cookie, but never test for it! I must have been interrupted while I was writing that bit! Thanks for letting me know! ______ Conan: "Reading through your ad-system and how it manages user clickthroughs, I noticed a little "flaw" (or "feature", in case you already knew about it). It's not a flaw that is bad for your advertisers. Far from it; it could be losing you money! Lets see... Only one application variable for storing used IP addresses? Shouldn't you set up a variable for EACH advertiser? This would mean that someone could hit your site, click an ad and that would be it. If he came back to your site again and clicked a different ad, the clickthrough would not be registered and you would have given away a free clickthrough! P.S. Love the new-look site - looks like the best just got better.You should definitely use JScript.NET not C# for CoverYourASP.NET ;-) Oh, and I hope you enjoyed Florida!" Me: What led me to that decision were spiders. I wanted to play it safe for my advertisers, and if a spider hit the site "clicking" on every banner I wanted to minimize the damage. I still think that keeping advertisers happy is worth a lot! P.S. You're losing the fight for Jscript.NET - everyone else wants C#. :-( ____________________________________________________________         A   W O R D   F R O M   M Y   S P O N S O R S      http://www.hexillion.com/refer.asp?id=cya7&dest=%2F ____________________________________________________________ Get FREE sample code, online utilities, and articles at Hexillion.
