I was wondering if there is a way to OVERLOAD Functions and Subs in classic ASP.
It would be very usefull...
Any tricks, ideas?

Classic ASP won't let you use overloads per se, and, if I remember correctly, you cannot use real VB parameters (like Optional ByVal ... As [Type]). I suppose the thing to try is to see if you can pass an array or a collection and have the function or sub behave differently depending on the number of elements in the list.
*thinking out loud* Also, if you define a function or sub with multiple parameters, and fail to pass one or more, does it error out at runtime? If it doesn't, you might be able to test using IsEmpty or IsNull or something on a param that wasn't passed...
Then again, you could define subs and functions in a VB6 DLL project with method signatures that use the Optional in the parameters list, making the sub or function "overloaded" and then calling the methods of the DLL from your classic ASP page...

Unfortunatelly it throws an error on runtime...
I have been spending 3 days to try and find a way to overcome this VBscript limitation and the only solution that is feasible is the ARRAY solution.
Thank you anyway...

I am using geocities to host my website, they offer an HTML editor. What I am trying to do is find out what OS the user is running, and load the page accordingly. In code it would look something like this:
if the user is running Windows XP
{
Set the web page text to "You are running XP";
{
else
{
Set the web page text to "Your are not running Windows XP";
}
how would I go about doing this? Any help is appreciated

To the best of my knowledge, no. The best you can do is determine that they are running "Win32", which is exposed in JavaScript as navigator.platform:
<!-- details omitted... -->
function window_onload() {
window.alert(navigator.platform)
}
<!-- details omitted... -->
<body onload="return window_onload()">

U can use Server object in ASp. It will provide u full information about what O.S. is running,Ur System Configuration and other system information. So try to find out the solution by using Server Object.

The previous, anonymous post would be correct, assuming you have the ability to write server-side code in something (PHP,ASP,ASP.NET,etc); however, given your example, I assumed that you don't have that capability, and are limited to JavaScript.
It might be feasible to do something with a Java Applet, but of course, that only works for users of your site with Java Runtime Environment installed.

I'm at the stage where I'm testing out my form. Everything works (error validation, sending data, sending auto reply) except sometimes it doesn't want to save the values of my radio buttons and textboxes. Should I be requesting those variables a different way? Please advise. Here's the form - http://www.csudh.edu/mcnair/application.asp
Gracias,
Donna

Donna,
Are you saying that it doesn't retain the values of the radio buttons when you post the form, and that you cannot access the values using Request(item) or Request.Form(item)? Or that you post the form and expect to see the values subsequent page displays?

Basically, my radio and text box values aren't kept whenever I get an error on my form. Yet, when I fill out my form completely, it works fine - goes to thank you page and sends me my data via email. I could send you my code if that helps.

I am assuming from the URL that you listed that you are using "classic" ASP -- ASP 2.0 or 3.0; this was one of the tragic flaws of form handling with ASP. ASP does not, by default, retain any state for the values a visitor enters in form fields on an HTML form. However, there is hope -- several folks have written things, like this one[^] that will assist with retaining the state of form controls on subsequent round trips.

Donna,
Overall, I must say you've produced very nice, clean ASP code, which is a hard thing to do, considering most people's propensity to write spaghetti ASP code...
So, only two observations:
1) To create the radio groups, both initially and on subsequent postbacks, I'd use a helper function, like this:
<%
Function WriteRadioGroup(Name, Items, selectedItem)
' By the way, I wrote this at warp speed, without actually running to check it
Dim i, strChecked
For i = 1 To UBound(Items)
If Items(i-1) = selectedItem Then
strChecked = " checked"
Else
strChecked = ""
End If
Response.Write("<input type=""radio"" name="" & Name & "" value="" & Items(i-1) & """ & strChecked & ">")
Next
End Function
%>
For this method to work, you'll have to declare arrays up top for the radio button groups:
<%
Dim aYearLevel(3)
aYearLevel(1) = "Sophomore"
aYearLevel(2) = "Junior"
aYearLevel(1) = "Senior"
%>
Then, in-line with the HTML:
<% WriteRadioGroup("sYearLevel", aYearLevel, sYearLevel) %>
That way, when the group is created, it checks to see if the value of a button in the group should be checked or not, and writes the appropriate attribute to the correct item, in this case the attribute of "checked"
On the text areas, I think all you need to do is to stick the value in between the TEXTAREA tags:
<TEXTAREA NAME="sFieldStudy" VALUE="" COLS=40 ROWS=8><% =(sFieldStudy) %></TEXTAREA>
and those values will show up on subsequent page displays as well.

In my application, one of the form enables end user to upload files.On web server side I am doing HTTP uplad.So far so good accept since "Network Service" account does that for me on IIS 6.0 (IIS 6.0 uses this inbuilt account - for newbies).Instead inbuilt account I would like to have seperate account do that for me.So I will have one account with read/write permission that I can use for upload.Can I run one form that enables upload to run under one say windows integrated account?
Can I do <"Identity Impersonate=true Username=abcd Password =pqrs> just for single form ? Any ideas.
Does any one know if I should be concern about giving "Network Services" account Read/Modify/Write access to harddrive ?

You can place that form in a separate directory with a separate web.config using the impersonation for parts of the application in that directory.
It might be possible to temporarily impersonate an account, using a method outlined here[^]. If you get that to work out, let me know...

Also, I would stick with impersonating a unique account created specifically for this purpose, or using the ASPNET worker process account and giving the account only the permission it needs, and only for a particular directory. Do not grant other accounts (Administrator, Run As Service) permission under your web application, as those kinds of accounts can be exploited, leaving your web application, your server, your network vulnerable to more kinds of attacks.

I can't seem to understand why IE 6 and Netscape 7 render a specific page of mine differently. I have an unordered list within a table division and everything looks OK except for when the list ends. In Netscape there is no extra "space" added to the end of the list whereas in IE6 it adds an extra line (blank of course) like padding.
Is this normal behavior of IE? I can get rid of it by omitting the tag but I definetely don't want to do this. Can I overcome this w/ CSS somehow?

I've tried and tried to do this successfully. The most I ever achieved was to set the blocking around a UL to zero at the top and zero at the bottom, but then wherever I used this, I ended up adding extra BR's and P's anyway. If someone else has a great solution to this, please let me know, too?

Does anybody know a program that will turn the .txt file IIS made into a certificate (.cer). In other words sign it.
and I already tried openssl, and it dosn't work for me....

nevermind. server 2003 has a tool to do it.
anyone want a ssl certificate from the Alex Egg CA???

Hi,
I'm calling for some script which displays info according to category.
This is how i do it :
<!--#include virtual="/cgi-bin/info_by_category.pl"-->
It works , but currently it always displays the same default category.
Now , the problem : I dont know what category i gonna use. It comes through URL , because the URL looks like this :
www.mydomain.com/info.html?category=1
where the number "1" can be any number from 0-9.
The perl script cant retrieve this info through
$ENV{'QUERY_STRING'}
because i call the script without any parameters.
I'd like somehow to add category number when calling
the script IN RUNTIME (!)
<!--#include virtual="/cgi-bin/info_by_category.pl?category=x"-->
where the "x" is category number passed in URL ,
but dont know if its possible.
Help needed!
Thanks in advance
I tried adding it with JavaScript but id didnt work out ;(

Why use SSI at all if you have perl at your disposal?
You're really using the wrong tool for the job here. SSI is really intended for adding simple dynamic information (e.g. dates, hit counters, document modification dates, etc.). It's support for variables, conditionals, and dynamic string manipulation (which you apparently need) are very limited if they exist at all.
It seems to me that the only way to do what you want is to dynamically load your page that contains the SSI. At that point, it seems just silly to be using SSI at all. PHP or Perl itself would be much more capable to do what you want.
Here's a couple of questions that may help if you're insistent on using SSI:
1. Where are you obtaining the category id from. Is it just hard coded in a hyper link? If so, then why not just make your hyperlink point the cgi itself passing the appropriate id directly?
2. Can you use perl or php along with SSI? If so, to do what you want would be as simple as:
<?php
$categoryID = $HTTP_GET_VARS["category"];
echo "<!-- #include virtual=\"/cgi-bin/info_by_category.pl?category=$categoryID\"-->\n";
?>
3. Can you get rid of SSI altogether? If so, just move your perl script code into a CGI that draws everything you need and then runs the info_by_category.pl code. The url would then just be:
<a href="/cgi-bin/info_by_category.cgi?category=1">Info</a>
Let me know if you need any clarification.
Best Regards.

Matt, thanks for your reply.You're right - capabilities of SSI are very limited , but i still successed to do what i wanted 
Here's how i do it :
