A simple Java GUI question: Why the hell doesn't this work .

Link to workspace is here: http://www.2shared.com/file/EpirAeqg/Othello.html

GameBoard is a simple JPanel that is filled with 8x8 small tiles (just like a chess board). Nop java-gui is the worst shit that ever landed on PC. What am I missing?

It sounds like you need Javascript (<3 jQuery) to add in new fields as needed. The files can be accessed easily with a foreach over $_FILES['userfile']. You can then use file_get_contents to get the data directly, or you can copy the file to another location if you only want to save it.

I don't know how I missed this post.

Ok, so the code I provided IS javascript that helps to create a new field for more uploads. However I can't access more than one file if I dynamically allocate the number of forms using java. I do use $_FILES and the code works fine, when I create a set number of forms for attachments. I've given up on the issue though. It seems only google knows how to implement the feature, and if people need to submit more attachments to email, they should compress them into a zip file.

<script type="text/javascript">
moar = function()
{
    var formEl = document.createElement("div");
    var inputEl = formEl.appendChild(document.createElement("input"));
    inputEl.name = "filez[]";
    inputEl.type = "file";
    document.getElementById("f").insertBefore(formEl, document.getElementById("moar"));
}
window.onload = function()
{
    document.getElementById("moar").onclick = moar;
    moar();
}
</script>
<div>Submitted data:<pre>
<?php
if (isset($_FILES))
    var_dump($_FILES);
?>
</pre>
<form method="post" action="asdf.php" enctype="multipart/form-data" id="f">
<span style="color:blue;text-decoration:underline;cursor:pointer" id="moar">Moar</span>
<br>
<input type="submit" value="Submit">
</form>

array(1) {
  ["filez"]=>
  array(5) {
    ["name"]=>
    array(2) {
      [0]=>
      string(10) "aaaaaa.txt"
      [1]=>
      string(7) "bbb.exe"
    }
    ["type"]=>
    array(2) {
      [0]=>
      string(10) "text/plain"
      [1]=>
      string(24) "application/x-msdownload"
    }
    ["tmp_name"]=>
    array(2) {
      [0]=>
      string(23) "C:\WLMP\TMP\phpE2DF.tmp"
      [1]=>
      string(23) "C:\WLMP\TMP\phpE2E0.tmp"
    }
    ["error"]=>
    array(2) {
      [0]=>
      int(0)
      [1]=>
      int(0)
    }
    ["size"]=>
    array(2) {

Frigo, why do you want final methods (or classes for that matter)? They smell like bad design a lot and that stuff doesn't belong to C++ (there's a reason it's not natively supported and isn't part of C++0x). I've never used them and never saw a reason to. In Java it seemed like another one of those obsolete safety features which enabled you to say to another programmer who is a potential evil villain and who is playing around with your classes: "Hey you idiot, don't override this method or you'll break something!".

Nobody should ever want to override methods of classes about which he doesn't know anything about anyways. And if you're using them yourself you should know what to override and what not to override anyways.

It takes up to 24 hours, be patient (the NS you're querying is also caching the results).

On the php side... google is your friend. You're probably gonna need to check if $_FILES['your_field_name'] is set, then run a foreach loop over $_FILES['your_field_name']['tmp_name'] in which you do sth like $contents = file_get_contents($foreach_var). Then check if the reading succeeded with if ($contents === true) and do sth with $contents.

Hello TL,

I am a computer science major at UCSD. Recently, at the place I'm interning at, I got involved in a discussion about the future of the computer science degree. The guy I was talking with said in about 10-15 years, computer science will closely resemble a liberal arts degree, of sorts. He said that computer science by itself is useless and it's much better if you major in math, physics, biology, or something else and use computer science as a tool to help you get your job done. Furthermore, he said that basic computer science courses will probably be turned into GEs due to how helpful they can be to pretty much everybody.

What do people think about this?

That guy's full of shit. If anything, CS degrees are becoming more and more like Engineering degrees (which is why many schools now lump them into the same area). I'm not quite sure how you could say that computer science by itself is useless. Yes, CS can be helpful for solving problems in many realms, but it is also an end unto itself. Furthermore, like many other degrees, CS majors do not need to be a jack-of-all trades to be useful. As long as you have someone that can give you requirements, and/or describe things to you in a way that lets you develop requirements, you can develop software without in-depth understanding of the subject you are developing for.

Does anybody know some good books/guides for code design? I know the basics of programming and can get my way around code, but my code isn't really that elegant, well commentated, or structured that well (in other words, a design nightmare). I'm looking for a book to help me teach myself design methods, any suggestions?
