  • Handling apostrophes, php and pgsql

    - by running4surival
    For my forms, I'm using pg_escape_string on every field before I insert them into the database. So I get something like firstname='O''reilly'. But when I try to print that out, I get O''reily, 2 apostrophes. Shouldn't it only 1 apostrophe, O'reilly? This isnt a debugging problem, im just wondering if you have firstname='O''reilly', how do you print that so it is just O'reilly instead of O''reilly?

  • How can I make a simple path generator?

    - by user360737
    Hi all, I have a link that I have to repeat 50 times, for each folder, and I have 15 folders.the link that I have to repeat looks like this: <a href="update/images/Cars/car (x).JPG" rel="lightbox[cars]"></a> now, the jpg files are named car 1- car 50. and I would really like to be able to generate this script so that I can input the path "update/images/Cars/" the picture title (car) and the input the number of times that I need this link, and then have it spit out something that looks like this: <a href="update/images/Cars/car (1).JPG" rel="lightbox[cars]"></a> <a href="update/images/Cars/car (2).JPG" rel="lightbox[cars]"></a> <a href="update/images/Cars/car (3).JPG" rel="lightbox[cars]"></a> <a href="update/images/Cars/car (4).JPG" rel="lightbox[cars]"></a> <a href="update/images/Cars/car (5).JPG" rel="lightbox[cars]"></a> <a href="update/images/Cars/car (6).JPG" rel="lightbox[cars]"></a> and then it keeps repeating, I'm assuming this can be done with a counter, but I'm not sure. Thanks!

  • how to deal with the position in a c# stream

    - by CapsicumDreams
    The (entire) documentation for the position property on a stream says: When overridden in a derived class, gets or sets the position within the current stream. The Position property does not keep track of the number of bytes from the stream that have been consumed, skipped, or both. That's it. OK, so we're fairly clear on what it doesn't tell us, but I'd really like to know what it in fact does stand for. What is 'the position' for? Why would we want to alter or read it? If we change it - what happens? In a pratical example, I have a a stream that periodically gets written to, and I have a thread that attempts to read from it (ideally ASAP). From reading many SO issues, I reset the position field to zero to start my reading. Once this is done: Does this affect where the writer to this stream is going to attempt to put the data? Do I need to keep track of the last write position myself? (ie if I set the position to zero to read, does the writer begin to overwrite everything from the first byte?) If so, do I need a semaphore/lock around this 'position' field (subclassing, perhaps?) due to my two threads accessing it? If I don't handle this property, does the writer just overflow the buffer? Perhaps I don't understand the Stream itself - I'm regarding it as a FIFO pipe: shove data in at one end, and suck it out at the other. If it's not like this, then do I have to keep copying the data past my last read (ie from position 0x84 on) back to the start of my buffer? I've seriously tried to research all of this for quite some time - but I'm new to .NET. Perhaps the Streams have a long, proud (undocumented) history that everyone else implicitly understands. But for a newcomer, it's like reading the manual to your car, and finding out: The accelerator pedal affects the volume of fuel and air sent to the fuel injectors. It does not affect the volume of the entertainment system, or the air pressure in any of the tires, if fitted. Technically true, but seriously, what we want to know is that if we mash it to the floor you go faster..

  • Drupal 7: Create a taxonomy term for each node and use the node title as the term name

    - by Spre3
    Is there anyway of doing this by using rules or by some custom code? I did try using rules but I can't find a way of adding a new term and set the name as the node title because the [node:title] token is not avilable. I know this is possible using the NAT module but the way this module changes the taxonomy terms hierarchy if you add a term reference field that uses the same taxonomy vocabulary which ruins the whole purpose of what I am trying to do.

  • Python coin-toss

    - by Andy
    i am new to Python, and i can't wrap my head around this. I have following function defined: def FlipCoins(num_flips): heads_rounds_won = 0 for i in range(10000): heads = 0 tails = 0 for j in range(num_flips): dice = random.randint(0,1) if dice==1: heads += 1 else: tails += 1 if heads > tails: heads_rounds_won += 1 return heads_rounds_won Here is what it should do (but apparently doesn't): flip a coin num_flip times, count heads and tails, and see if there are more heads than tails. If yes, increment head_rounds_won by 1. Repeat 10000 times. I would assume that head_rounds_won will approximate 5000 (50%). And it does that for odd numbers as input. For example, 3, 5 or 7 will produce about 50%. However, even numbers will produce much lower results, more like 34%. Small numbers especially, with higher even numbers, like for example 800, the difference to 50% is much narrower. Why is this the case? Shouldn't any input produce about 50% heads/tails?

  • Running code/script as a result of a form submission in ASP.NET

    - by firmbeliever
    An outside vendor did some html work for us, and I'm filling in the actual functionality. I have an issue that I need help with. He created a simple html page that is opened as a modal pop-up. It contains a form with a few input fields and a submit button. On submitting, an email should be sent using info from the input fields. I turned his simple html page into a simple aspx page, added runat=server to the form, and added the c# code inside script tags to create and send the email. It technically works but has a big issue. After the information is submitted and the email is sent, the page (which is supposed to just be a modal pop-up type thing) gets reloaded, but it is now no longer a pop-up. It's reloaded as a standalone page. So I'm trying to find out if there is a way to get the form to just execute those few lines of c# code on submission without reloading the form. I'm somewhat aware of cgi scripts, but from what I've read, that can be buggy with IIS and all. Plus I'd like to think I could get these few lines of code to run without creating a separate executable. Any help is greatly appreciated.

  • PHP/MySQL time zone migration

    - by El Yobo
    I have an application that currently stores timestamps in MySQL DATETIME and TIMESTAMP values. However, the application needs to be able to accept data from users in multiple time zones and show the timestamps in the time zone of other users. As such, this is how I plan to amend the application; I would appreciate any suggestions to improve the approach. Database modifications All TIMESTAMPs will be converted to DATETIME values; this is to ensure consistency in approach and to avoid having MySQL try to do clever things and convert time zones (I want to keep the conversion in PHP, as it involves less modification to the application, and will be more portable when I eventually manage to escape from MySQL). All DATETIME values will be adjusted to convert them to UTC time (currently all in Australian EST) Query modifications All usage of NOW() to be replaced with UTC_TIMESTAMP() in queries, triggers, functions, etc. Application modifications The application must store the time zone and preferred date format (e.g. US vs the rest of the world) All timestamps will be converted according to the user settings before being displayed All input timestamps will be converted to UTC according to the user settings before being input Additional notes Converting formats will be done at the application level for several main reasons The approach to converting time zones varies from DB to DB, so handing it there will be non-portable (and I really hope to be migrating away from MySQL some time in the not-to-distant future). MySQL TIMESTAMPs have limited ranges to the permitted dates (~1970 to ~2038) MySQL TIMESTAMPs have other undesirable attributes, including bizarre auto-update behaviour (if not carefully disabled) and sensitivity to the server zone settings (and I suspect I might screw these up when I migrate to Amazon later in the year). Is there anything that I'm missing here, or does anyone have better suggestions for the approach?

  • Saving order of a List in JPA

    - by Rosen Martev
    Hello, I have the following question about JPA: Can I save the order of the elements in a java.util.List? In my application the order in which I put elements in the Lists is important but after I get those collections from the database the order is not the same (as expected). Can you show me a way to deal with this problem? P.S. There is not a field in the entities that I put in the collections by which I can order them. Rosen

  • Sequential (comb) GUIDs for Oracle

    - by Eyvind
    We are in the process of switching from the C# Guid.NewGuid() random-ish guid generator to the sequential guid algorithm suggested in this post. While this seems to work well for MS SQL Server, I am unsure about the implications for Oracle databases, in which we store guids in a raw(16) field. Does anyone have any insight as to whether this algorithm would be good for creating sequential guids for Oracle as well as for MS SQL Server, or if a different variant should be used. Thanks!

  • jquery event handler- trigger function upon specific key and action

    - by Gal
    Background story: when a user selects a portion of text in a text field with her mouse (mark it up manually), and subsequently hits "alt" key, a certain function would trigger. My questions are: How can I trigger a function when a user hits a key (in her keyboard)? How can I preserve a portion of text selected, and use it as a parameter for that function? I've tried looking up online but haven't found any good answers, but i'd greatly appreciate links as well.

  • Selecting a form which is in an iframe using jQuery

    - by Khnle
    I have a form inside an iframe which is inside a jQuery UI dialog box. The form contains a file input type. The jQuery UI dialog contains an Upload button. When this button is clicked, I would like to programmatically call the submit method. My question is how I could select the form which is in a iframe using jQuery. The following code should clarify the picture: <div id="upload_file_picker_dlg" title="Upload file"> <iframe id="upload_file_iframe" src="/frame_src_url" frameborder=0 width=100% scrolling=no></iframe> </div> frame_src_url contains: <form action="/UploadTaxTable" enctype="multipart/form-data" method="post" id="upload-form"> <p>Select a file to be uploaded:</p> <p> <input type="file" name="datafile" size="60"> </p> The jQueryUI dialog box javascript code: $('#upload_file_picker_dlg').dialog({ ... buttons: { 'Close': function() { $(this).dialog('close'); }, 'Upload': function() { $('#upload-form').submit(); //question is related to this line $(this).dialog('close'); } }, .... }); From the javascript code snippet above, how can I select the form with id upload-form that is in the iframe whose id is upload_file_iframe ?

  • Is this an acceptable use of "ASCII arithmetic"?

    - by jmgant
    I've got a string value of the form 10123X123456 where 10 is the year, 123 is the day number within the year, and the rest is unique system-generated stuff. Under certain circumstances, I need to add 400 to the day number, so that the number above, for example, would become 10523X123456. My first idea was to substring those three characters, convert them to an integer, add 400 to it, convert them back to a string and then call replace on the original string. That works. But then it occurred to me that the only character I actually need to change is the third one, and that the original value would always be 0-3, so there would never be any "carrying" problems. It further occurred to me that the ASCII code points for the numbers are consecutive, so adding the number 4 to the character "0", for example, would result in "4", and so forth. So that's what I ended up doing. My question is, is there any reason that won't always work? I generally avoid "ASCII arithmetic" on the grounds that it's not cross-platform or internationalization friendly. But it seems reasonable to assume that the code points for numbers will always be sequential, i.e., "4" will always be 1 more than "3". Anybody see any problem with this reasoning? Here's the code. string input = "10123X123456"; input[2] += 4; //Output should be 10523X123456
