  • jquery add remove objects

    - by Scarface
    Hey guys quick question, I have an add remove script that will add a unique element and should remove it on a click function but does not. I think it is because the added object is not in the DOM when page is loaded but I am not sure how to fix this. IF anyone has any advice I would greatly appreciate it. $(document).ready(function(){ if (action=='content-change'){ $('#droppable2-inner').empty().append('<div id="content-image"><img id="visual-background2" src=' + src + '></div><div id="drop-content" action="drop-image">x</div>'); } $("#drop-content").click(function() { $('#content-image').remove(); }); })

  • php/mysql question, retrieving information

    - by chance
    Hey SO, I have a question, pretty new at PHP and MySql but was curious is it possible to display only the most recent column to a table, from a database? I know it is possible to display a list of all information, or if you have just one column of information in your table to display that using the Here is my code for my basic script (just loads 1 column of information) I would like it to only print out the recent column i added to the table $con = mysql_connect ("localhost","username","password"); if (!$con) { die ('Could not connect:' . mysql_error()0; } mysql_select_db("db_name", $con); $result = mysql_query(Select column FROM table"); while($row = mysql_fetch_array($result)) { echo $row['column']; } mysql_close($con); * keep in mind, im not looking for someone to shoot me my code with it completed, though it would be handy, however just giving me the options of what I have to do, or what the script is called would be plentiful enough for my research, thanks!

  • how to do collision detection for hollow(?) movieclips in flash AS3?

    - by Pieter888
    Hey everyone, I'm making small interactive games in flash to learn AS3, now I ran into a problem that I need some help with. I need to check the collision between the player and the wall which is normally simple using the hitTestObject function. But now I made a wall object totally surrounding the player with corridors and turn, a collision playground so to speak. Now when I use the hitTestObject function to check whether the player is in collision with the wall it tells me it always collides supposedly because the player object is within the bounds of the wall object. So assuming that I'm correct about the error: How can I prevent getting a collision when I'm inside the bounds of the wall object but not touching the actual walls in that object?

  • Getting URL of executing JavaScript file (IE6-7 problem mostly)...

    - by TooTallNate
    Hey all, I've been trying to throw together a generic function that retrieves the absolute URL of an executing JavaScript file on a web page: http://gist.github.com/433486 It works great in almost all the browsers I've tested (Firefox, Chrome, Safari, Opera v10 at least, and IE 8). It seems to fail, however, in IE 6 and 7. The callback function gets executed, but the retrieved name is simple the URL to the main HTML page, not the JavaScript file. So all I'm really asking is if there's some other way of getting the URL of the current JavaScript file (which could be IE 6 and 7 specific)? Thanks in advance!

  • Storing SQL in MySQL: Insert as Text?

    - by Tim F
    Hey all, Working in a team environment, each one of us has put together our own list of SQL statements that we use to help with our day to day job functions. As the case often is, there may be some redundancy with this, and we are often in need of each other's statements. To circumvent this, I'm looking to put together a small app that can be used to store and search for these SQL statements. To begin with, I'm keeping it basic, just storing and searching the statements. This may build out to be the actual execution at some point in the future, but I'm not concerning myself with this at the time. This will be built with PHP and MySQL - Should I store the SQL as text, or is there something that I need to be concerned with?

  • J2ME linking interfaces.

    - by user554031
    Hey guys, I've been working with J2ME for a short while, however I've been unable to find anything regarding my query. I'm wanting to link interfaces, I.E A to B to C. Similar to a card layout. Information on each interface changes based on the choices the user made previously. For example City - Cinema - Cinema Listings. The eventual target is to create a MIDlet that displays information from a database (I understand a midlet needs to connect to a servlet which connects to the DB). Thanks in advance for you're time.

  • PHP Detect Pages Genre/Category

    - by Alexwhin
    Hey, I was wondering if their was any sort of way to detect a pages genre/category. Possibly their is a way to find keywords or something? Unfortunately I don't have any idea so far, so I don't have any code to show you. But if anybody has any ideas at all, let me know. Thanks! EDIT @Nican Perhaps their is a way to set, let's say 10 category's (Entertainment, Funny, Tech). Then creating keywords for these category's (Funny = Laughter, Funny, Joke etc). Then searching through a webpage (maybe using a cUrl) for these keywords and assigning it to the right category. Hope that makes sense.

  • [C++] Passing around objects to network packet handlers ?

    - by xeross
    Hey, I've been writing a networking server for a while now in C++ and have come to the stage to start looking for a way to properly and easily handle all packets. I am so far that I can figure out what kind of packet it is, but now I need to figure out how to get the needed data to the handler functions. I had the following in mind: Have a map of function pointers with the opcode as key and the function pointer as value Have all these functions have 2 arguments, packet and ObjectAccessor ObjectAccessor class contains various functions to fetch various items such as users and alike Perhaps pass the user's guid too so we can fetch it from the objectaccessor I'd like to know the various implementations others have come up with, so please comment on this idea and reply with your own implementations. Thanks, Xeross

  • Object still linked (referenced) after selecting it out of list?

    - by djerry
    Hey guys, I was wondering, and i'm not really sure, but help me out here. If you have a List items, and there's one object you need to change a property of it. Say myClass has a string property "status". I'm searching my list with a for-loop and i get my object so i do myClass item = items[i]; if i want to change the "status" property, i do this for example : item.Status = "new status"; My question/issue is this: is "item" still linked to the list item, so that if i execute the line above, it will be changed in the list as well without having to set this : items[i] = item; Hope this is clear. Thanks in advance.

  • Problems with the Enterframe Event

    - by user434565
    Hey guys, I have been developing a game using Flex, and used the Timer class to keep the main loop going. However, when I tried using the enterFrame event to do the main loop, there were a few problems. First of all, physics simulation seemed way too fast. Is the enterFrame event called more than once per frame? I set the application's global frame rate to 24, so shouldn't the application set off the event every 1/24 of a second? And the second problem is that when the game runs like this, some MXML components that are added are not shown. I have absolutely no idea why this happens. Help me please?!? Thanks.

  • Qt QMainWindow at Close

    - by Cenoc
    Hey, this may seem like a very simple question, but I want to dump some data whenever the QMainWindow closes, so I used the following piece of code: QObject::connect(MainWindow.centralwidget, SIGNAL(destroyed()), this, SLOT(close())); but this doesnt seem to make it call close(). Am I doing this wrong? Isnt the centralwidget suppose to be destroyed? Or perhaps the application closes before close() can be called? Any other ways of doing it then? Thanks in advance!

  • equivalent to getch(), mac/linux crash

    - by acidzombie24
    Hey guys. So I am using getch() and my app crashes instantly. Including when doing: int main() { getch(); } I can't find the link but supposedly the problem is, it needs to turn off buffering or something strange along those lines and I still want cout to work along with cross platform code. I was told to use std::cin.get(), but I'd like the app to quit when a key is pressed, not when the user typed in a letter or number then press enter to quit. Is there any function for this? The code must work under Mac (my os) and Windows.
