 | Use [icode]<pre></pre>[/icode] or [icode]<code></code>[/icode] tags around it like: [code=html] <pre> #include <iostream> int main(int argc, char** argv) { std::cout << "Hello World!\n"; return 0; } </pre>[/code] Note the [icode]<[/icode]. Make sure you encode any HTML entities (<, >, &, etc.) so they don't get mixed in with the markup  |
| | It does save newlines, but my guess is that on output you're not using nl2br. The browser ignores newlines when rendering text unless it is in a <pre>, <code> or tag with white-space:pre applied. So yeah, use nl2br or get a rich-text editor  |

| | [icode]../images/[/icode] The .. means up one directory, so [icode]../images/[/icode] really says [icode]htdocs/mysite/images/[/icode]. It would probably be better to use the absolute path but you haven't posted one so I don't know you're directory structure :) |

| | You would setup a server-side script (using PHP or ASP or whatever your language is) that uses cURL or whatever your language uses to make and output the response. Then your AJAX call just points to your script. [code]RemoteServer ------------------- somefile.php MyServer ----------------- myapifile.php `- Make request to RemoteServer.com/somefile.php `- … |
| | The example you described isn't AJAX, that's just standard Javascript validation. AJAX would be, for example, as the user types display a list of possible selections underneath the box. [url]http://w3schools.com/ajax/ajax_intro.asp[/url] |

| | A) Use [icode] <script type="text/javascript>[/icode], not [icode]<Script language="JavaScript">[/icode], it's old and the language attribute is deprecated B) Your code doesn't actually do anything since it's never called (or at least, it'll always fail as soon as the page loads C) [code=html] <head> <script type="text/javascript"> var validateUsername = function () { …  |

| | [quote]Show all steps and derivations to receive full credit.[/quote] Sounds like you better get going. You could start by showing us some of what you've tried already or by explaining bits you don't understand. After all, this is your first post so maybe you missed the GIGANTIC text at the … |

| | None that I know of. That's a very strange question for a programming language. It's not like using PHP kills babies or something. The only thing that could even be remotely construed as an ethically related issue is the decision between open/closed source which I'll let you search for on … |

| | _ is usually associated with gettext with deals with text localization. |
| | It's syntactically correct and there's really no harm in it except for the fact that its a complete waste since the reason you have a function returning a value is because you want to use it. If you don't want to return a value then a function returns void. [code=c] …  |
| | Try actually putting something in your catch statement. And if you're not getting anything there then take the old-fashioned approach and just put asserts/couts along your code to see where it dies [CODE=c++]catch (sql::SQLException &e) { }[/CODE] |
| | [code=php]$row=mysql_fetch_array($result); $vValue = $row['vValue'];[/code] You're fetching one row before your while loop so its essentially doing nothing with the first row |

 | A) Don't bump like that, its annoying. B) Try Element.prototype. If that doesn't work I have no idea since both Object.proto... and Element.proto... worked for me. |

| | You create your list as [icode]list <char>[/icode] but your function prototype never defines a template type, you just have [icode]list[/icode]. So you could either make the function templated or you can always assume [icode]<char>[/icode] [code=c++] template <typename T> void sort(list<T> ch) { ch.sort(); } sort<char>(ch); // or void sort (list … |

 | Re: Fill Function Hmm, have you seen sprintf or does this serve a different purpose? This could be great if the function took, say, a callback function that could be used to validate fields that were passed to it. |
| | I would suggest that you think of a way to make it a bit more secure than simply posting any email you get to the web but if that's what you want to do IMAP is probably the way to go. [url]http://php.net/imap[/url] |

| | Here's a hint: You want to use both. The PHP shouldn't be a "backup" since you can't trust client-side validation. Client-side validation is nice to give users some feedback but it can also be malicious. |

 | You would use the function just like you would inside another function. With the example code afunction isn't defined (there is no prototype.) You could do something like this [code=c++] void afunction(); // function prototype class example { public: example(); ~example(); void doSomthing() { afunction(); } }; void afunction() { … |
