  • Enumerate printers on a Mac

    - by Kirk Backus
    So, I'm familiar how to enumerate the printers using the Windows API, there are a ton of examples out there. What I gathered from here is that I can find the printers in the /Library/Printers/ directory. When I searched there, I found more folders which didn't really mean anything to me. To keep it simple, how do I query the mac to get a list of printers (local and networked) "attached" to the system? Or can anyone point me in the right direction?

  • pagination - 10 pages per page

    - by arthur
    I have a pagination script that displays a list of all pages like so: prev [1][2][3][4][5][6][7][8][9][10][11][12][13][14] next But I would like to only show ten of the numbers at a time: prev [3][4][5][6][7][8][9][10][11][12] next How can I accomplish this? Here is my code so far: <?php /* Set current, prev and next page */ $page = (!isset($_GET['page']))? 1 : $_GET['page']; $prev = ($page - 1); $next = ($page + 1); /* Max results per page */ $max_results = 2; /* Calculate the offset */ $from = (($page * $max_results) - $max_results); /* Query the db for total results. You need to edit the sql to fit your needs */ $result = mysql_query("select title from topics"); $total_results = mysql_num_rows($result); $total_pages = ceil($total_results / $max_results); $pagination = ''; /* Create a PREV link if there is one */ if($page > 1) { $pagination .= '< a hr_ef="?page='.$prev.'">Previous</a> '; } /* Loop through the total pages */ for($i = 1; $i <= $total_pages; $i++) { if(($page) == $i) { $pagination .= $i; } else { $pagination .= '< a hr_ef="index.php?page='.$i.'">'.$i.'</a>'; } } /* Print NEXT link if there is one */ if($page < $total_pages) { $pagination .= '< a hr_ef="?page='.$next.'"> Next</a>'; } /* Now we have our pagination links in a variable($pagination) ready to print to the page. I pu it in a variable because you may want to show them at the top and bottom of the page */ /* Below is how you query the db for ONLY the results for the current page */ $result=mysql_query("select * from topics LIMIT $from, $max_results "); while ($i = mysql_fetch_array($result)) { echo $i['title'].'<br />'; } echo $pagination; ?>

  • Are parametrized calls/sanitization/escaping characters necessary for hashed password fields in SQL queries?

    - by Computerish
    When writing a login system for a website, it is standard to use some combination of parameterized calls, sanitizing the user input, and/or escaping special characters to prevent SQL injection attacks. Any good login system, however, should also hash (and possibly salt) every password before it goes into an SQL query, so is it still necessary to worry about SQL injection attacks in passwords? Doesn't a hash completely eliminate any possibility of an SQL injection attack on its own?

  • Is it possible to use SQL XML to insert, and get output from each record?

    - by nbolton
    I would like to perform a SQL XML insert (on MSSQL), and in this case I need to insert a list of files into the DB (this is simple enough). However, there's an auto generated PK column (ID), and I need the ID for each newly created filename without performing a 2nd query. Is this possible? I guess it doesn't matter if the result is/isn't XML, but the input certainly has to be.

  • Drawbacks of using an integer as a bitfield?

    - by Mark
    I have a bunch of boolean options for things like "accepted payment types" which can include things like cash, credit card, cheque, paypal, etc. Rather than having a half dozen booleans in my DB, I can just use an integer and assign each payment method an integer, like so PAYMENT_METHODS = ( (1<<0, 'Cash'), (1<<1, 'Credit Card'), (1<<2, 'Cheque'), (1<<3, 'Other'), ) and then query the specific bit in python to retrieve the flag. I know this means the database can't index by specific flags, but are there any other drawbacks?

  • What is the best approach using JDBC for parameterizing an IN clause?

    - by Uri
    Say that I have a query of the form SELECT * FROM MYTABLE WHERE MYCOL in (?) And I want to parameterize the arguments to in. Is there a straightforward way to do this in Java with JDBC, in a way that could work on multiple databases without modifying the SQL itself? The closest question I've found had to do with C#, I'm wondering if there is something different for Java/JDBC.
