  • The date is always ignored

    - by TheLearner
    I cannot understand why the date is never set in the title - it's always ignored and if I swap around the date and the title, then the title is ignored! -(id)initWithCoordinate:(CLLocationCoordinate2D)c title:(NSString *)t { [super init]; coordinate = c; NSDate *today = [NSDate date]; [self setTitle:(@"%@%@", [today description], t)]; //[today release]; return self; }

Pseudo-code: function myFunction() { startProcess(); return $something; } function startProcess() { sleep(5); // Do stuff that user doesn't should have to wait for. }

  • Why thread started by ScheduledExecutorService.schedule() never quits?

    - by moonese
    If I create a scheduled task by calling ScheduledExecutorService.schedule(), it never quits after execution, is it a JDK bug, or I just miss something? note: doSomething() is empty method below. public static void doSomething() { } public static void main(String[] args) { ScheduledFuture scheduleFuture = Executors.newSingleThreadScheduledExecutor().schedule(new Callable() { public Void call() { try { doSomething(); } catch (Exception e) { e.printStackTrace(); } return null; } }, 1, TimeUnit.SECONDS); }

  • "SELECT DISTINCT" ignores different cases

    - by powerbar
    Hello, I have the problem, that MSSQL Server 2000 should select some distinct values from a table (the specific column is of the nvarchar type). There are the sometimes the same values, but with different cases, for example (pseudocode): SELECT DISTINCT * FROM ("A", "a", "b", "B") would return A,b But I do want (and do expect) A,a,b,B because they actually are different values. Any idea how to solve this problem? Thanks a lot in advance!

  • IE is doing strange things with JQuery

    - by Syncopated
    So ... The thing is, the code works in FireFox, no problems. But when I open the same page, it gives me the following error: "Undefined is null or not an object." But when I copy the code to a localhost page, it works fine. Also when I clear my cache in IE it works, but only once, if I refresh after that one load, it gives me the same error. Here is the code: <script type="text/javascript" src="datepicker/js/jquery-1.4.2.min.js"></script> <script type="text/javascript"> var count3 = 0; var count5 = 0; var count2 = 0; var count4 = 0; $(document).ready(function(){ $('#switch3').click(function(){ $('#switchDiv3').slideToggle(350); if(count3 == 0){ count3 = 1; document.getElementById('switchImage3').src = "images/ArrowDown.png"; return; } else { count3 = 0; document.getElementById('switchImage3').src = "images/ArrowRight.png"; return; } }); ... (this is the code for each item that is generated) </script> And the code that determines the div that should hide: <table width="100%" border="0" cellspacing="0" cellpadding="0" align="center"> <tr> <td width="20" align="center" valign="top" style="padding-right: 3px"> <a style="cursor: pointer;" id="switch3"><img width="20" height="20" src="images/ArrowRight.png" id="switchImage3" style="border-style: solid; border-width: 1px; border-color: black;"/></a> </td> <td> <div id="switchDiv3"> <div align="left"> (Contents of the div here) </div> </div> </td> </tr> </table> Any help is appreciated! Thanks in advance
