DZone Snippets: hack code

Include text files in C source

scvalex (Alexandru Scvortov) — Mon, 01 Oct 2007 10:04:48 GMT

This includes the contents of myfile.txt into the char array text.

Note: This only works if ALL lines in the file are enclosed in "s.

Wrong myfile.txt:
Hello world
Goodbye world

Right myfile.txt:
"Hello world"
"Goodbyle world"
""



char text[] = {

#include "myfile.txt"

Multiple user accounts hack for zenPhoto

Multiple user accounts hack for zenPhoto

I needed support for several users, not really for any fancy reason, just so there was no password sharing, so here's a quick hack I made that shouldn't be hard to extend to be a bit more useful if you desire.

Hopefully I have used this forum's tags correctly. If I haven't perhaps a mod can lend a hand in rectifying them. :)



In admin-functions.php:

After:

	echo "\n  ";

Add:

	echo "\n  ";



Before:

  echo "\n  ";

Add:

  echo "\n        "> users";



In admin.php

After:

    } else if ($action == 'settheme') {

      if (isset($_GET['theme'])) {

        $gallery->setCurrentTheme($_GET['theme']);

      }

Add:

	  

/** USERS ******************************************************************/

/*****************************************************************************/



    } else if ($action == 'updateUsers') {

		$uid = explode("_",$_REQUEST['userid']);

		$uid = $uid[1];

		$name = $_REQUEST['username'];

		$pass = $_REQUEST['userpass'];

		$email = $_REQUEST['usermail'];

		$query = "SELECT * FROM users WHERE name='$name' LIMIT 1";

		$result = mysql_query($query) or die(mysql_error());

		if (mysql_num_rows($result)<1){

			//create new user

			$query = "INSERT INTO users (`name`,`pass`,`email`) VALUES ('$name',MD5('$pass'),'$email')";

			$result = mysql_query($query) or die(mysql_error());

			$r = mysql_insert_id();

			die("$r");

		}else{

			//update old user

			$query = "UPDATE users SET ";

			$query .= "name='$name'";

			if (!empty($pass) && ($pass!="")){ $query .= ",pass=MD5('$name')"; }

			$query .= ",email='$email'";

			$query .= " WHERE id='$uid'";

			$result = mysql_query($query) or die(mysql_error());

			die("Save successful!");

		}

    } else if ($action == 'removeUsers') {

		$uid = explode("_",$_REQUEST['userid']);

		$uid = $uid[1];

		$query = "DELETE FROM users WHERE id='$uid' LIMIT 1";

		$result = mysql_query($query) or die(mysql_error());

	}



Before:

Execute this SQL on your zenphoto table:

CREATE TABLE users (

`id` INT( 255 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,

`name` VARCHAR( 255 ) NOT NULL ,

`pass` VARCHAR( 255 ) NOT NULL ,

`email` VARCHAR( 255 ) NOT NULL

);



INSERT INTO users (`name`,`pass`,`email`) VALUES ('admin',MD5('password'),'you@yourdomain.com');

	Name	Password	Email
	Add User
Delete \| Edit	".$r['name']."	Saved	".$r['email']."

I recommend also changing the password info in the config file to something uninteresting.

Also, as always, I recommend doing a full backup before proceeding with these directions. YMMV. These directions are provided as-is with no warranty express or implied. You use this at your own risk.

Linux : Open, Copy and Paste, Mouse or keyboard? Who cares - with this.

MattScilipoti (Matt Scilipoti) — Mon, 14 Aug 2006 08:47:48 GMT

From http://news.u32.net/articles/2006/07/31/shell-vs-file-manager:

Would you rather click on files or type at them? This is the root of a dichotomy that has existed ever since day one (day one was some time in mid 1964 according to my sources). Except for TwoDudes' short-lived FinderShell, I have never seen a program that effectively combines the strengths of each environment. Why must we choose?

Here's a stupid trick that makes it easier to move data from mouse mode to finger mode and back. Add the following to ~/.bashrc or equivalent:



alias open=gnome-open

alias copy="xclip -i"

alias paste="xclip -o"

Now open opens pretty much anything:



open mswd.doc

opens mswd.doc in OpenOffice or AbiWord (whatever your default is).



open tt.mov

opens the QuickTime clip in a movie player.



open .

opens a new Nautilus window showing the current directory.



open http://u32.net

opens a new browser window showing this blog.

And copy and paste manipulate the clipboard:

* paste (with no arguments) prints the clipboard to the terminal.
* Select some text in a text editor and then run paste > newfile to save that selection to a file.
* copy bigfile copies the contents of bigfile into the clipboard.
* copy *.log copies the contents of all log files in the current directory.

Of course, you can combine these tricks:



paste | tr a-z A-Z | copy

converts the contents of the clipboard to upper-case.



paste | tr A-Za-z N-ZA-Mn-za-m | copy

will rot13 the clipboard.

Lightbox with IFrames

timmorgan (Tim Morgan) — Wed, 09 Aug 2006 20:42:14 GMT

A hacked version of lightbox that uses an IFrame when the url points to anything other than a jpeg. Also, added some syntax that allows a link to specify the height of the lightbox like this:

LB with height 300
