so i finally got a copy of adobe cs3 and flex builder2. flex is amazing, combining mxml and actionscript 3 together into a seamless package. now that im on the as3 tip, i decided to dive into papervision3D. pv3d is a set of actionscript classes that are used to create 3D objects within the flash environment. it's currently in beta and the source code is only available to osflash emailing list members. so if you want it signup here. thanx to carlos for creating pv3d, and to his girlfriend for convincing him to release the project open source!

<?php
$email = 'someone@somewhere.com';
if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) {
    //invalid email
} else {
    //valid email
}
?>

here's a simple SQL script that returns the last row created. this is great for when you add a new record that has an autogenerated id and you need that number.

mssql

CREATE PROCEDURE [dbo].[getLastLogin]
AS
SELECT TOP 1 *
FROM dbo.login
ORDER BY id DESC
GO

mysql

SELECT * FROM `login` 
ORDER BY `id` DESC
LIMIT 1,1;

i was having some trouble at work creating form buttons with graphics for reset buttons. i just thought someone might be interested in my non-javascript solution:

<button style="background: none; border: none;">
<img src="reset.jpg" alt="" />
</button>

here's a nice little snip of c# code. this is meant to be used in an asp.net web application. the following code will return either a querystring variable or a post variable, it tries both and finds the valid one.

public string RequestParam(string paramname)
{
    string result = string.Empty;
    if (Context.Request.Form.Count != 0)
    {
        result = Convert.ToString(Context.Request.Form[paramname]);
    }
    else if (Context.Request.QueryString.Count != 0)
    {
        result = Convert.ToString(Context.Request.QueryString[paramname]);
    }
    return (result == null) ? string.Empty : result.Trim();
}

place this code in a file called index.cgi, chmod it to 775, and place it in a directory of html files. this script will pick one of the files in the specified directory at random, and print it to the screen. refresh the page for a new random one.

#!/usr/bin/perl
print "Content-type: text/html\n\n";
 
#print "<pre>";
$basep = "/wwwroot/path2/randomdir";
 
srand(time ^ $$);
#print "got random time...\n";
 
@files = `ls $basep/*.html`;
#print "got file list...\n";
#foreach (@files) { print "-----$_\n";}
 
$file = rand(@files);
#print "got random file...$phrase\n";
 
$nupath = "$files[$file]";
#print "got new path...$nupath\n";
 
open(LOG, $nupath) or die "$!\n"; 
while () 
{
  print $_;
}
close (LOG);
#print "</pre>";

exit;
