• when does java.util.zip.ZipFile.close() throw IOException?

  - by sk

  Under what circumstances would java.util.zip.ZipFile.close() throw an IOException? Its method signature indicates that it can be thrown, but from the source code there doesn't seem to be any place where this could happen, unless it's in native code. What corrective action, if any, could be taken at the point where that exception is caught?

  I have a DELETE query which deletes a record from a mysql db. is there any way to make sure if the delete was performed or not?

• Java 1.7ea: Files.probeContentType(path) returns null

  - by Cybertizzen

  Hi, I'm having a bit of a strange problem with an application using the Files.probeContentType(path)-method to test for file type: On both my Ubuntu and Fedora systems, it works fine, but when moved to a RedHat Enterprise server (2.6.18-194.el5 #1 x86_64 x86_64 x86_64 GNU/Linux), it only returns null. I'm using java 7 early access (1.7.0-ea-b84). I have to use this version due to functionality that isn't included in 1.6. Does anyone have an idea of what might be the problem here?

• How to add a UIView above the current UITableViewController

  - by user558096

  I'm have difficulty adding a subview UIView from within the viewDidLoad method of a UITableViewController This works: [self.view addSubview:self.progView]; But you can see the table cell lines bleed through the UIView progView. I've tried this approach: [self.view.superview insertSubview:self.progView aboveSubview:self.view]; Which is an attempt to add the progView UIView to the superview, above the current view. When I try this I get this the UIView never appears.

• Timing issue with jQuery and $(document).ready()

  - by ripper234

  I have the following code block code when the document is ready: $(document).ready(function() { createDivs(); // creates some divs with class 'foo'; // iterate $(".foo").each(function(index) { alert(index + " - " + $(this).text()); }); } I find that the "iterate" part misses the divs I created in the createDivs() method entirely! Is there some timing issue I'm not aware of? Why doesn't jquery see the divs that were just created?

• Protecting from crashes (beyond bounds) with [object objectAtIndex:]

  - by Tom

  Hi! I'd like to know if there's a way to verify if an index exists before getting it. So it'd be way to protect my code against: *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (2) beyond bounds (0)' Like in PHP you can do: isset($object[10]); and it'll return true if it exists. Is there such a method in Objective-C/Cocoa? Thanks!

• Javascript Date: Ensure getMinutes(), getHours(), getSeconds() puts 0 in front if necessary

  - by Mega Matt

  Hi all, Looking for a creative way to be sure values that come from the getHours, getMinutes, and getSeconds() method for the javascript Date object return "06" instead of 6 (for example). Are there any parameters that I don't know about? Obviously I could write a function that does it by checking the length and prepending a "0" if need be, but I thought there might be something more streamlined than that. Thanks.
