After much searching this morning, I think I found a credit card validation javascript that will work for the project I'm doing: here.

If you know of others please pass on the links! (10 points if you find one in ASP!) 😉

I stumbled across this article over at DevArticles. 10 PHP Functions I bet you didn't know about. (I didn't)

I talked about stored procedures here the other day. Today, I needed to create a page that would call one of those stored procedures (the selecting one) and display all data from a table. This code is very plug-and-play-ish – very little needs to be modified (that is, as long as you're using MS SQL Server). If all you need to do is a "screen dump" of everything in the table, this ASP takes care of everything for you… (it even uses an ASP version of the alternating color rows PHP script snippet I had posted awhile back here.

Hugh sent me an email telling me about a service called voicemonkey that he's developing. (Ok, I almost insta-deleted the email because I thought it might be spam. LOL!) But I signed up to give the service a try and it's pretty cool. (and FREE! at least for now while it's in beta-test mode) There's a few different levels you can sign up for – but the "blog" level I did works like this: there's one link (it never changes) and it will play you the latest message I've left. (Which in my case will likely always be the same, unless I get adventurous and start using it all the time.)

So if you've always wondered what I sounded like, if I had a NY or Boston accent, sounded like a wacko or whatever – Here's your chance to find out.

A few links I wanted to note…

Simon Willison: CSS ain't Rocket Science (RSS ver.)
Looks like some interesting tutorials there. [link via Kristine]

Font Browser
A neato Flash thingy that will show you the fonts you have installed on your machine with a little sample on the side. You can change the sample's text and size. [link via Jennifer's ETC.]

Debugging PHP
A little tutorial on how to figure out why your code doesn't work – when it… uh… doesn't work. ;0) I was actually considering writting a similar tutorial – listing just a few of the errors that I've come to know and love hate 😉 and what they mean to me. (from a "where do I look to fix it" perspective – not like an "I'm personally attached them" one) LOL! Maybe that'll be my weekend project… [link via Donna]

I know there was a few other links I wanted to take note of that I saw earlier this week… but now I can't find them (guess I should have made this post sooner. LOL!)

update: Here's one I wanted to add:
Dot Project
If you need a (free!) project management package – I installed this one and so far it's pretty cool!! It's actually got a lot more than what I needed, and the "trouble ticket" feature needs a little work (it doesn't email the person assigned when a trouble ticket is first created) but it's still in beta, so maybe they'll be fixing that soon. In either case, I'm really liking this so far and haven't found too much else (that's free!!) that does what I need…

I've been learning about stored procedures and calling them from ASP pages. So just wanted to jot down some examples/templates…

(note from my technical editor, Mike: This code is specific to MS SQL Server and probably wouldn't work with other databases.)

John (no URL provided) sent me a question based on some problems he was having with a javascript he had written. I've seen this happen with a few people now so I think a "tip" is in order. In javascript, ASP, and PHP(?) (and I believe other scripting and programming languages) – you can not have a number (ie. Integer, Float, etc.) with leading zeros. If you do – it will think it's something else (specifically a hexidecimal, or octal number.)

Here's a definition of hexidecimal and octal numbers I found here:

Hexadecimal and Octal numbers may also be represented in JavaScript. A hexadecimal number (base 16) is represented with a leading 0x, or 0X. The case of the X represents whether to use upper-case of lower-case letters for the hexadecimal number. Octal numbers are represented with a leading 0.

(don't ask me to explain hexadecimal or octal numbers more than that. I've never had to use them, and I don't know how I would. I only understand the textbook explanation you see above. LOL!)

If you have a number with leading zeros, and you need to KEEP the leading zeros, you need to treat it like a string. (i.e. put quotes around it).

So let's say you have a function that takes an ID number. Your ID number has leading zeros. (Lets say this function simply needs to take your number and forward you to a page with the ID number as the "name" of the page).

function fakeFunction(id) {
document.location= id + ".htm"
}
… some code …
<a href="#" onClick="fakeFunction(00123)">This link to page 00123 won't work</a>
but
<a href="#" onClick="fakeFunction('00123')">this one will</a>

If you want to see what it's reading (and this is a really good bugtesting tip in general) put in an alert. So make this the first line in your function:

alert(id)

In this example – the first link will pop up an alert that says "83" (I guess 00123 is the octal (?) equivalent to 83) the second will pop up the correct value; "00123".

Additionally – if you're populating a database – and the database is expecting a *NUMBER* you can't pass it a string. So if you've made your number with leading zeros into a string – you won't be able to put it into the database. If your "id" field is set to accept a number, this insert statment will give you errors:

INSERT into student (name, id) values ("Joe Schmo", "00123")

It needs to be this:

INSERT into student (name, id) values ("Joe Schmo", 123)

Yes, the leading zeros are gone. I suggest adding them in later (or changing your field type). You can easily add leading zeros to a number in php using the sprintf function like this

$aNumberThatsAString = sprintf("%05d"."id");

Breaking that down: %0 (pad with zeros) 5 (so that there are 5 "digits") d (this is an integer/decimal number)

Feel free to add to this or correct me in the comments. Some of the above may be incorrect assumptions…

A short article showing how to use CSS pseudo-classes to help users find hard to spot links on an otherwise well designed page. This involves using the :hover pseudo-class on paragraphs, so you'll need to use the newest version of Mozilla (1.3) to get the full effect!

(update: this technique has also been confirmed to work in Netscape 6+, Opera 7, Safari, and Konqueror.)
