  • Can the memory used by MKMapView be released some how?

    - by gdr
    I am using an MKMapView in my iPhone application. When I load this view, the activity monitor instrument shows that the real memory of my App is increasing significantly. It keeps going up as you move the map around or zoom in and out. Once the View controller that loads this view is removed, the memory that was allocated due to the usage of the mapView does not get freed up. Is there something that can be done to get all this memory back?

  • Java. Best procedure to de-serialize a Java generic object?

    - by Jake
    What is the best procedure for storing and retrieving, using native Java serialization, generic objects like ArrayList<String>? Edit: To clarify. When I serialize an object of type ArrayList<String> I'd like to de-serialize to the same type of object. However, I know of no way to cast back to this generic object without causing warnings.

  • How to iterate with Selenium RC over XPath results directly?

    - by Gj
    I'm currently resorting to first doing a get_xpath_count, and then creating a loop incrementing an index variable, which in turn I inject back into the original xpath to select the nth result... very awkward no doubt. Is there some simple, direct, elegant way to iterate directly over the xpath results? Thanks!

    - by user956424
    I wish to disable loading the plone site if JS is disabled in the browser. Where exactly do I change the code? Which template/skin do I choose? I want to ensure that JS is always enabled while browsing any part of the plone site. While browsing, if JS is disabled, I can redirect to another page with tag to enable the JS in the browser and give a hlink to the site back if it is enabled. I am using Plone 4.1

    - by HollyStyles
    Gah! this is really causing me hassle today. Suddenly without warning '@' (at symbol) and '"' (double quote) are trading places on my keyboard but ONLY in Visual Studio 2008 !!! I can't seem to find anything in help or online to explain/remedy this. Is there some keyboard shortcut I am inadvertantly executing?? I rebooted my PC and it went away for an hour or two and then suddenly came back. Oh the insanity :(

  • How can I shuffle an NSArray?

    - by Mr. McPepperNuts
    All examples I find on shuffling arrays are for NSMutableArrays. Copying an NSArray to an NSMutable array, shuffling, then copying back always crashes the application. Is it even possible to shuffle an NSArray? Anything in objective-c similar to Collections.shuffle() (Java)?

  • enabling the "return button" in a UITextField keyboard (objective-c/iphone)

    - by peter61
    When I start editing a UITextField, I have the "Clear When Editing Begins" option checked so it starts off with no text. However, the "Return" button is grayed out until you type at least one character. I've seen other iphone apps where the "Return" button is not grayed out (and if you press it with no text, then it goes back to what the text used to be). How is this done? Thanks.

  • jQuery Validator's "required" not working when value is set at statup

    - by nandrew
    Hello, I have a problem with jQuery Validator. I want to use "required" property on a text input. It doesn't work when input has set value attribute by HTML code (tested on Firefox (3.5), and on IE 8 - on IE it works a bit better). Story: 1. Page loads; 2. value is cleared; 3. focus is changed. 4. Nothing happens but the error message should be displayed; 5. getting back to the field and typing some characters. 6. changing focus; 7. getting back to the field; 8. clearing the field. 9. Error is displayed even before leaving the field. The HTML code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <script src="Web/Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="Web/Scripts/jquery.validate.js" type="text/javascript"></script> </head> <body> <form id="form1"> <input type="text" id="name1" name="name1" value="test" /><br /> <input type="text" /> </form> <script type="text/javascript"> $(document).ready(function() { var validator = $("form").validate({ rules: { name1: { required: true, minlength: 2 } }, messages: { name1: "bad name" }, }); }); </script> </body> </html>

    Hi, I include several images of eps format in latex. After latex command, there are some of the images missing in the dvi file. Not sure if it is related to the image size, most of the images missing have size around 83kB while those shown up have a size less than 40kB. After conversion from dvi to ps, the images are all back. Just wonder what is the reason causing the images missing in dvi file? Thanks and regards!
