What is this doing. What do these variables do mean?

$a = $row['workingtime'];
$b = $row['workedtime'];

1. You send email, regardless of whether If condition is true or false.
2. While loop isn't closed ('}')

Re: Which framework should I learn?

@evstevemd
I was wondering if you could give me your thoughts on a couple of frameworks I've seen on the web. one of the is X-Jax from http://www.xajax-project.org/ and Lithium from http://lithify.me/ I'm trying to learn how I can make a website that utilizes AJAX heavily while still working in a MVC framework (I hope thats possible).
Thanks to everyone for your great suggestions

I won't suggest you go for ajax-ified framework. I would say Check framework and Ajax library. as for me I will say take Codeigniter and JQuery :)

Re: SDL, Unicode, and Trash

If you don't mind Try wxWidgets. from version 2.9.x you can use wxBase which have no GUI components Just console. Remember to compile with unicode flag set.

wx is known to work with Unicode "naturally" when compiled with Unicode. also there is wx-SDL tutorial.

Re: Which framework should I learn?

I have been a professional developer since before the web came along. .....But PHP is 10 + years old. Yes there are billions of site written it it. Just as there were billions of lines of COBOL and FORTRAN 20 years ago. Now they are extinct.

Do you mean because it is 10+ old it is outdated like the two? Professional developer giving such statement? No way :-O

May be We should throw the outdated C++ before PHP since it have been long way 1979. PHP have been around since 1995. C language is supposed then to be in trash cans as it is even older than C++.

No offense intended but your "professional" is questionable due to criteria you set. may be after seeing your posts in this PHP section we can confirm your claims to professionalism. Also I hope the two links (which I didn't visit) are not Marketing links :)

Re: Passing a non-static member function as argument

I have made quite a lot of use of polymorphism, and turning out to be very useful :)
Pretty much have my code working now, however the results are not what I expect; so some more debugging to do to make sure there aren't any silly errors anywhere.

Re: database not displaying in form

The code works, but the incorrect data is not being displayed in the form. In the form, I a getting the character '/', and that is all. I have a column called fname that has names stored. The name is not showing up at all.
Here's what I am using for my code:

<?php 
session_start();  
 
if (!isset($_SESSION['memberusername'])){  
	header("Location: contractorlogin.php");  
	exit();  
}

mysql_connect('localhost','name','pword') or die( mysql_error() );
mysql_select_db('databasename') or die( mysql_error() );
$user = mysql_real_escape_string($_SESSION['memberusername']);
$sql = "SELECT Username FROM contractors WHERE Username='" . $user . "'";
$result = mysql_query($sql) or die( 'Unable to execute<br>'.$sql.'<br>'.mysql_error());
	   ?>
	<html>
	    <body>
	        <form>
            <?php
               while($rows=  mysql_fetch_array($result)){
                   echo "<input type='text' name=$rows[0] value=$rows[1] /> <br />";

Re: Form Post to DATABASE from MySQL Query output

Thanks evsteve...this current code doesn't seem to work. It wont update the database. I am looking for help to get this to work and I think I am close.

I will advice you the best way to do these stuffs. Get your copy of MySQL workbench and connect to your local copy (remote site?) and test queries. Tweak them until they work. Transfer query to PHP. MWB have got syntax highlighting. You can also create view that acts as a table with all sums you need!

Re: database not displaying in form

Wrong code...

else
{
    $row=mysql_fetch_assoc($result);
    echo '<table><tr><th>' .implode('</th><th>', array_keys($row) ).'</th></tr>';
    do
    {
        echo '<tr><td>'.implode('</td><td>',$row).'</td></tr>';
    }while($row=mysql_fetch_assoc($result));
    echo '</table>';
}

You wrote

while($row=mysql_fetch_assoc($result));

fist of all, it's

while(condition){ /*repeat something until it's false*/ }

Right code...

else
{
    while($row = mysql_fetch_assoc($result)){
        echo '<table><tr><th>' .implode('</th><th>', array_keys($row) ).'</th></tr>';
        echo '<tr><td>'.implode('</td><td>',$row).'</td></tr>';

Re: Can you password protect a dll?

\
This won't be a issue at all.There are something called one way security architecture.
Just reverse engineering the decrypt/encrypt (encryption engine) algorithm does not
violate the confidentiality or integrity as long as you are using asymmetric encryption
engine.You can use a client library which is static or even use templates where you
need to reveal the source code of the engine.It doesn't matter.

But when the code is loaded into the memory and the encryption engine had successfully
ran over it, there no longer be confidentiality on the machine code level.

The bottom line of my post was, you can try hard but if they try harder...

Re: Can you password protect a dll?

Thanks, I successfully created a sample dll last night, the walkthrough didnt help as much as I'd hoped (I am using visual studio).
I had to just write the functions like so..
extern "C" int __stdcall ...
and then make a .def file to export them.
But I cobbled one together in the end using a few different snippets found in various places.
Always willing to try a new IDE though, thanks.

Poor __stdcall ;)
Check __declspec dllexport/dllimport

Re: Can you password protect a dll?

>> I'm now off to learn how to compile to dll in C++, maybe it will hook me
Assuming you have some version of Visual Studio, you might go through MSDN's Walkthrough: Creating and Using a Dynamic Link Library. It's close to the simplest console app/dll configuration that one can have.
P.S. I think you should not underestimate the cheat team's capability/motivation to hack the protection (due to their young age) - there are lots of resources on internet to aid in just that - in other words, be sure to give this a good go ;)

I have found CodeLite to be easiest IDE I have ever used. Microsoft VS is a way too complex, at least for me but many out there loves its debugging capabilities. CL have projects for DLL for both Linux/Windows.
