Solved the problem by forcing the page to post the data into same page, when I press the "Submit" -button. But not a very nice way to solve a simple data handling, is it? Sigh | :sigh:

But the challange is still on, to find a solution that does it without making a "post". Unsure | :~

Any suggestion or contribution is most welcome! Smile | :)

When you specify the file to create you have to specify the full path, otherwise the default directory will be used, which is probably in some temp directory somewhere. Do it like this:

Set streamfile = fso.CreateTextFile(server.mappath("blahblah.asp"),True)

What is the difference between .asp, .htm, .html?

DanYELL10-Dec-03 7:49

I have seen websites where all the pages have the suffix
.asp and I have seen websites where all the pages have
the suffix .htm. Is there a difference between the two
files?

What really bothers me is I have a site where everything
is .asp and when I send this robot to crawl the site and
find all links, it only finds the first page. I want
google and other search engines to crawl all the pages
(and subpages of the site) and the .asp suffix seems to
hinder it.

Am I just imagining this or is something really different
between those suffixes?

Please, any response any one can give me will be greatly
appreciated.

Sincerely,
Danielle (an overworked graduate student)

The suffix is a clue as to what inline scripting language the site uses (e.g. .asp, .php, .shtml, etc.), but is by no means definitive (the web server can be configured map any suffix to any handler). .htm is usually just plain HTML, but on a platform with historical roots to three-character file extensions (e.g., Windows).

I doubt the .asp extension is hindering the web crawler, unless it is poorly designed. However, there are lots of reasons why a web crawler for a search engine (such as Google) may not completely cover your site. Are all of your internal links of the form "blah.asp?something"? If so, the crawler is probably avoiding following the link since it suggests that the link is dynamic and the bot designers don't want the bot to waste server resources by triggerring a potentially intensive query. Also, a robots.txt file may be instructing the bot to specifically ignore certain sections.

the extension tells the server what type of processing it must do to the file before it sends it to your browser. HTML and HTM files require no server-side processing and are simply sent as-they-are to your browser. ASP files use the VBScript or JScript server-side scripting language, and the server will look through these files for any script code and process it first before sending the resultant HTML to your browser. PHP files are the same idea, but use a different language.

Search engines are not a straight-forward technology. There are entire business devoted to optimising people's sites to please the search engines. What have you used to build the site? Search engines can't navigate flash files in general, and if you use a cryptic method to link to your subpages they may also have trouble. Do you use frames? These can cause problems also. What's the URL of your website? If we can have a look, you might get some better help.

Regular Expression e-mail verification

10-Dec-03 5:34

Hi there!

I'm most certain this topic has been discussed previously hundreds of times, yet I have a little problem with this which probably deserves a new thread:

I built a few days ago a regular expression email verification (actually copy-pasted it from some place I can't remember now :-P) to be used to filter email input in a web-page I'm working on.
Yesterday my boss called very angry because one of his clients wasn't able to enter his email. Obviously the client's email was a valid one and my function was rejecting it, so I have to correcti it. The problem was my regexp wasn't allowing the address to start with a digit (doh!):

^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$

Ok, solving this is most easy, but my boss was so damn angry, he told me to be absolutely sure all valid email addresses will be accepted when I fix it... so I made my homework... I ran into RFC2821 and RFC821 to check out SMTP rules, and found something weird:

According to RFC821 (http://www.faqs.org/rfcs/rfc821.html), the syntax for the email address is as follows (check the original RFC821 for a complete explanation, I'm filtering out a lot of stuff here):

<mailbox> ::= <local-part> "@" <domain>
<local-part> ::= <dot-string> | <quoted-string>
<dot-string> ::= <string> | <string> "." <dot-string>
<string> ::= <char> | <char> <string>
<char> ::= <c> | "\" <x>
<c> ::= any one of the 128 ASCII characters, but not any <special> or <SP>
<x> ::= any one of the 128 ASCII characters (no exceptions)
<SP> ::= the space character (ASCII code 32)
<special> ::= "<" | ">" | "(" | ")" | "[" | "]" | "\" | "." | "," | ";" | ":" | "@" """ | the control characters (ASCII codes 0 through 31 inclusive and 127)

The logic to understand the previous is rather simple: <mailbox> is composed of <local-part> AND "@" AND <domain>. Then <local-part> is composed of <dot-string> OR <quoted-string>, and so on. I left <quoted-string> and <domain> out of this because the quoted-string is a more complex notation for the same thing, and domain suffers of the same problem I'll explain now:

If you check the ASCII table, and filter out the INVALID characters according to the previous rules (not taking in count that quoting a char with backslash -i.e. \% - allows to enter ANY character), the valid set of characters for an email address is (values in parenthesis are ASCII codes):

letters: a - z AND A - Z
digits : 0 - 9
extras : ! (33), # (35), $ (36), % (37), & (38), ' (39), * (42), + (43), - (45), / (47), = (61), ? (63), \ (92), ^ (94), _ (95), { (123), | (124), } (125), ~ (126)

Now let's review this: letters, no problem... digits, no problem... but hey!!... what happened with the extra symbols?? I'm not complaining about 45, 95 (which are very common in email addresses) but the remaining are ALSO VALID?? Could this be possible?

Now, I can build a regexp to accept all this "extra" symbols, but my question here is ARE THEY ACTUALLY VALID? most of all ARE THEY VALID ANYWHERE IN THE SYNTAX?

I hope someone has the patience to read all this and give any comments about this.

I think yes, they are allowed. Just as a sample, Lotus Notes often generates e-mails using:
! (33), # (35), $ (36), % (37), & (38), / (47)
Although I never saw the others, what's the problem with this? If it's allowed by the RFC, then it should be only a matter of using them on your regex.
BTW, do you know about RegexLib.com? You have a good probability of finding the regex you need there.

Jeff Friedl provides exactly such a regex conforming to RFC821 in his book, Mastering Regular Expressions, and the regex can be found here:
http://public.yahoo.com/~jfriedl/regex/code.html[^]

There is an expanded version of the regex in the Email::Valid Perl module.

Thanks a lot guys!! that really helped a lot (although the regexp found at that url was built in perl and I'm working with asp, but I can do it myself anyway Smile | :)

).
I was most worried about this because some of those simbols are often used when some people with too much time on their hands try to hack a web by cross-scripting, so those simbols are considered somewhat "harmful", but with the special characters out of question ("<" ">" "\") not much harm can be done.

Thanks again!!

Hi,

I've created a little webservice.
I want to query, update and delete datas from 2 tables
So I've created a SQLConnection and a SQLDataAdapter.
The problem is with the SQLDataAdapter. I don't know how to tell .Net that the 2 tables are linked and must work togheter.
I've tried to made this with the "Configure Data Adapter Wizard" but it doesn't work.
Any1 know good idea to help me ?
regards
Sybux

Hi ,
If you want to link 2 tables you can use dataset for that.
In the dataset itself you will have to define that relationship .
something like this
custDS.Relations.Add("CustOrders",
custDS.Tables["Customers"].Columns["CustID"],
custDS.Tables["Orders"].Columns["CustID"]);
I hope you are asking about this only.
thanks

Hi all,

Iam facing a problem while populating data into Microsoft tree view control(ActiveX control) in ASP. Iam able to populate the data but all the data is visible as parent node. Can anyone help me out of this situation. Its very urgent.

Thanks in advance.

The code iam using is as follows
--------------------------------------------------
sub treeview_Load()

set oList = document.treeview1

Dim nodX
Set nodX = oList.Nodes.Add(, , "dad", "Mike") ' A first sibling.
Set nodX = oList.Nodes.Add(, , "mom", "Carol")
Set nodX = oList.Nodes.Add(, , , "Alice")

' Marsha is the FirstSibling.
Set nodX = oList1.Nodes.Add("mom", tvwChild, , "Marsha")
Set nodX = oList1.Nodes.Add("mom", tvwChild, , "Jan")
Set nodX = oList1.Nodes.Add("mom", tvwChild, , "Cindy")
nodX.EnsureVisible ' Show all nodes.

' Greg is the FirstSibling.
Set nodX = oList1.Nodes.Add("dad", tvwChild, , "Greg")
Set nodX = oList1.Nodes.Add("dad", tvwChild, , "Peter")

FrontPage Server Extensions- 2000 or 2002?

ThomasH17-Dec-03 16:26

7-Dec-03 16:26

Hey guys, what's up? Just set up my remote server (using semi-isolated development mode) for web projects (namely C# ASP.NET projects), and found the info about updating to FPSE 2002.

I didn't think I -needed- FPSE, except that I don't want to run IIS on my development PC (Win2kPro). So I'm using my test server (Win2kServer) as a remote web server. Wound up with a ton of error messages (well, actually, only two), and found the answer in Microsoft KB # 320451. So apparently I need FPSE, because I really don't want IIS locally.

Anyway- should I upgrade the test server to FPSE 2002? Anyone done this? Any problems with it?

Or... like I said, I really don't want IIS running locally. But- I much rather like the idea of talking to my test server via a file share (wwwroot$). Would the ability to use a file share work if I installed IIS locally- but stopped the "World Wide Web Publishing Service" and the "IIS Admin Service"? That way, IIS gets installed on my client computer, but I'm wondering if ADSI (Active Directory Service Interfaces) would still work. The KB says it's integrated with IIS, but I'm not sure how. Did anybody try this? Or, /could/ anybody try this for me? I just tried to create a C# ASP.NET web application, and wound up with both of the error messages that KB #320451 talks about.

Oh, let me link up KB 320451 - click here for the article!

Thanks!!

Roger, thanks for the info!! I'll forget about FPSE 2002!

Do you use FrontPage to create your web projects? Just wondering if you know anything about my question regarding IIS (installing it locally but keeping the services and web page stopped, just to get the Active Directory Service Interfaces component installed.).

Thanks!

Roger Wright8-Dec-03 5:14

I didn't understand what you're trying to accomplish by installing IIS but leaving it off, so I didn't address that part. I leave IIS running all the time, but redirect the home directory to a different drive and host only one file on the default site (essentially a 'go away' page). Turning it off is no problem, but I suspect that the ADSI thing needs pages that are served, rather than merely shared. It's worth a try, though - I can't see that it would harm anything to try it.

"Your village called -

ThomasH18-Dec-03 7:12

I'm trying to follow the semi-isolated model of development, as written up in Microsoft's "Patterns & Practices" series. Find that document here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/tdlg_ch2.asp. Find another similar writeup here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vstechart/html/vetchWebProjectsSourceControlIntegrationInVisualStudioNET.asp.

So according to that KB 320451, IIS needs to be installed in order to get the ADSI component installed, and the IIS5 docs say that the IIS Admin Object exposes ADSI methods to configure the remote web server. But I don't want IIS running... so I was hoping that I could install IIS locally, keep it off, but get the ADSI functionality that would "find" my remote webserver.

Well, I gave it a shot, and I was wrong- on ALL counts. I installed IIS, kept all services and the default web page running, but still got the error messages from KB 320451.

For kicks I tried my idea of shutting all of IIS down and trying to create a web project, of course, the same error messages came up.

So apparently my computer doesn't like ADSI at all, and I can't use the file share option for creating a web project.

But... now I'm wondering if it's because of my domain layout. I work in two domains- production and test. Each domain has it's own DNS server, the two domains are completely isolated from each other. My workstation PC (Win2kPro) is a member of the production domain. I can access the test domain thru exploring "my network places", or doing a start/run/\\servername.

And then I'm back thinking to Active Directory Service Interfaces. The only Active Directory that I can see by exploring "My network places" is the ad for the production domain. I can't see any ad for the test doman. So that makes me wonder if my file share method is failing because VS.NET is search the Production domain for my remote web server, when in fact, it should be searching the Test domain!

Ugh. I'm a 1/2 step away from calling Microsoft on this one. This wasn't a big deal with Visual Studio 6.0, but then again, when I developed my ASP apps, I used Interdev 6.0 to just create standalone files on a share from the test domain- I never used Interdev to create an actual application via FrontPage.

The shame is that the best practice for using Visual SourceSafe is via a file share... which I can't seem to set up.

Thanks for the help!! If you (or anyone else!) has any other ideas, please let me know! I'm wasting so much time on this that it's not even funny...

Roger Wright8-Dec-03 8:33

Just a thought (I haven't explored this at all) but I've noticed some new user accounts added since installing IIS and the server extensions. One, of course, is the IUSR account to allow web access from outside, but there are others that appear to be service accounts. Possibly some of these have to be given permission on the test domain for the running services to find those shares.
