  • jQuery selector question

    - by Jakey
    I have a span and an anchor inside a table cell. I have the anchor set up to show a tooltip. I would like the text inside the span to be used for the tooltip. How can I select this text in jQuery? <td class="row-head" colspan="5"><span class="tip-text">Complete Coverage</span><a href="#" class="help"></a></td> JQuery code - the current selector always finds the first instance only for all tips. $(document).ready(function() { $('.help').qtip({ style: { name: 'cream', tip: true }, content: { text: $(this).find('span.tip-text').html() } }); }); Thanks

  • XCode won't open: "Mac OS X platform is missing"

    - by Jan Hettich
    XCode won't open. I had it running fine a couple of weeks ago. Now I get the following error message when XCode tries to open: Internal Error File: /SourceCache/DevToolsBase/.../XCPlatformSpecification.m Line: 438 Object: <XCPlatformSp(ecification> Method: loadAllPlatforms The Mac OS X platform is missing - cannot set a default platform. Any idea what caused this or how I can recover? Changes I have made to my system (Snow Leopard) in the last couple of weeks include (a) allowing Software Update to run and (b) installing Eclipse IDE. But the problem may or may not be related to these changes.

    - by zildjohn01
    I'm running PHP 5.3.0. I've found that the curly string syntax only works when the first character of the expression is $. Is there a way to include other types of expressions (function calls, etc)? Trivial example: <?php $x = '05'; echo "{$x}"; // works as expected echo "{intval($x)}"; // hoped for "5", got "{intval(05)}"

    - by contactmatt
    Would someone please explain to me what the below paragraph means? This is a snippet from "Design Patterns: Elements of Reusable OO software" Part of an object's interface may be characterized by one type, and other parts by other types.

  • Algorithm Question Maximize Average of Functions

    - by paradoxperfect
    Hello, I have a set of N functions each denoted by Fi(h). Each function returns some value when given an h. I'm trying to figure out a way to maximize the average of all of the functions given some total H value. For example, say each function represents a grade on an assignment. If I spend h hours on assignment i, I will get g = Fi(h) as my grade. I'm given H hours to finish all of the assignments. I want to maximize my average grade for all assignments. Can anyone point me in the right direction to figure this out?

  • SQL CASE WHEN NULL - question

    - by cc0
    Ok, so I'm trying to select an amount of rows from a column that holds the value 3, but only if there are no rows containing 10 or 4, if there are rows containing 10 or 4 I only want to show those. What would be a good syntax to do that? So far I've been attempting a CASE WHEN statement, but I can't seem to figure it out. Any help would be greatly appreciated. (My database is in an MS SQL 2008 server)

  • Question about ITextUndoHistory returned from TryGetHistory

    Everytime the IWpfTextView's TextBuffer changes I am trying to get the history's redostack and undostack and simply checking the count. When doing this I am encountering a "Method not supported exception" when trying to access the two stacks. Am I retrieving the history incorrectly or does VS not want me seeing/editing the contents of the stacks? I can post the code if necessary... Thanks, Nick

    I've made a global authentication via WCF to use with the most of our systems, but found that load data via WCF not very so fast. What I need to do now is verify every time that the page is loading if the user has access granted to that page.... Its a good pratice to go back in WCF request this info for every page that the user access?This will not slow down my entire system?

  • PHP Class Question

    - by Jerry
    Hi all I am trying to build a PHP class to check the username and password in MySql. I am getting "mysql_query(): supplied argument is not a valid MySQL-Link resource in D:\2010Portfolio\football\main.php on line 38" database has errors:" message. When I move my userQuery code out of my Class, it works fine. Only if it is inside my Class. I am not sure if the problem is that I don't build the connection to mysql inside my Class or not. Thanks for any helps!! Here is my code <?php $userName=$_POST['userName']; $userPw=$_POST['password']; class checkUsers { public $userName; public $userPw; function checkUsers($userName='', $userPw=''){ $this->userName=$userName; $this->userPw=$userPw; } function check1(){ if (empty($this->userName) || empty($this->userPw)){ $message="<strong>Please Enter Username and Password</strong>"; }else{ //line 38 is next line $userQuery=mysql_query("SELECT userName, userPw FROM user WHERE userName='$this->userName' and userPw='$this->userPw'", $connection); if (!$userQuery){ die("database has errors: ". mysql_error()); } if(mysql_num_rows($userQuery)==0){ $message="Please enter valid username and password"; } }//end empty check return $message; }//end check1 method }//end Class $checkUser=new checkUsers($userName, $userPw); echo $checkUser->check1(); ?> I appreciate any helps!!!!

  • Fibonacci Function Question

    - by DMan
    I was calculating the Fibonacci sequence, and stumbled across this code, which I saw a lot: int Fibonacci (int x) { if (x<=1) { return 1; } return Fibonacci (x-1)+Fibonacci (x-2); } What I don't understand is how it works, especially the return part at the end: Does it call the Fibonacci function again? Could someone step me through this function?

  • Android: SurfaceView and Z-Level Question

    - by JimBadger
    I have a FrameLayout containint first a SurfaceView, and second a RelativeLayout which in turn contians various Buttons and TextViews. Upon the canvas of the SurfaceView I am drawing numerous Bitmaps, and, via Touch and Motion Events am allowing the user to drag them around. These Bitmaps, when dragged around pass underneath the Buttons etc that are inside the RelativeLayout. Now, it's my (possibly mistaken) understanding that the "Z-level" of the SurfaceView, or whatever it has that passes for it, is entirely unrelated to the actual Z-level of the rest of the Layout. Is this the case? If so, how may I get around it, so that dragged Bitmaps are drawn ontop of other Views? Or what other way can I implement a full-screen canvas and yet not have my buttons etc act like the controls of an overlay. I guess what I actually need is an underlay, where touch events can still be picked up by the Buttons etc underneath. But I don't know how to achieve this, as, when redrawing my Canvas, I have to also redraw the background. Can I swap the order of the RelativeLayout and the SurfaceView inside the FrameLayout, and then make the background of the Canvas transparent? If so how? Will touch events still "fall through" to the buttons underneath? Thanks for bearing with me, I know I'm a bit of a waffler.

  • Design question for windows application, best approach?

    - by Jamie Keeling
    Hello, I am in the process of designing an application that will allow you to find pictures (screen shots) made from certain programs. I will provide the locations of a few of the program in the application itself to get the user started. I was wondering how I should go about adding new locations as the time goes on, my first thought was simply hard coding it into the application but this will mean the user has to reinstall it to make the changes take affect. My second idea was to use an XML file to contain all the locations as well as other data, such as the name of the application. This also means the user can add their own locations if they wish as well as sharing them over the internet. The second option seemed the best approach but then I had to think how would it be managed on the users computer. Ideally I'd like just a single .exe without the reliance on any external files such as the XML but this would bring me back to point one. Would it be best to simply use the ClickOnce deployment to create an entry in the start menu and create a folder containing the .exe and the file names? Thanks for the feedback, I don't want to start implementing the application until the design is nailed.
