  • NSNotification for UIMenuControllerWillShowMenuNotification

    - by Bob Keathley
    I am trying to use the NSNotificationCenter to get UIMenuControllerDidShowMenuNotification from a UIWebView. I have the following code in my ViewDidLoad method: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(menuControllerWillHide:) name:UIMenuControllerWillHideMenuNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(menuControllerWillShow:) name:UIMenuControllerWillShowMenuNotification object:nil]; And methods: - (void)menuControllerWillHide:(NSNotification *)notification { } (void)menuControllerWillShow:(NSNotification *)notification { [[self navigationItem] setRightBarButtonItem:highlightBtn animated:NO]; } But I never get the Notifications? Any help would be helpful

  • Fluent NHibernate: Entity from one table, but reference will map to another tables?

    - by Andy
    Given the following tables: Product ----------- ProductId : int (PK) ProductVersion : int ProductHistory ----------- ProductId : int (PK) ProductVersion : int (PK) Item ----------- ItemId : int (PK) ProductId : int (FK) -- ProductId + ProductVersion relates to ProductHistory ProductVersion : int (FK) And the following classes: public class Product { } public class Item { public Product Product { get; set; } } What I want to happen is this; we get a Product from the Product table, assign it to Item.Product property. But that Item.Product property should map to ProductHistory. The idea is that only the latest version of a product is in the main Product table, so we allow customers to search against that table (so that if each product has 4 versions and there are 1000 products, we only need to query though 1000 products, not 1000 products * 4 versions of each). Any idea how to acomplish this? Thanks Andy

  • How to get a list of unchecked checkboxes when submitting a form?

    - by SzamDev
    Hi I have this code for example : $b = ""; while ($row = mysql_fetch_array($rows)) { if ($row['enabled'] == 1) { $b = "checked"; } else { $b = "": } echo "<\input name='nam[$row[id]]' type='checkbox' value='$row[id]' $b /"; } When I execute this code, I will get a list of checkboxes, some of them are checked and others are not. I can use this code to get a list of checked checkboxes. if (isset($_POST['sub'])) { //check if form has been submitted or not $nam = $_POST['nam']; if (!empty($nam)) { foreach($nam as $k=>$val){ // proccess operation with checked checkboxes } } I need to know how I can get list of unckecked checkboxes after submitting the form. Thanks in advance.

  • Handling the distinction between undefined- and null-parameters in JavaScript

    - by Jakob
    I know very well that null and undefined are distinct in JavaScript. However, I can't seem to decide whether or not use that fact when my own functions are passed one of those as its argument. Or, expressed in a different way, should myFoo(undefined) return the same thing as myFoo(null) or is everything fine if it doesn't? Or, in yet another case, since myBar(1, 2, 3) is the same thing as myBar(1, 2, 3, undefined, undefined), should myBar(1, 2, 3, null, null) return the same thing as myBar(1, 2, 3)? I feel that there's potential for confusion in both cases and that a library should probably follow a convention when handling null/undefined. I'm not really asking for personal opinions (so please express those as comments rather than answers). I'm asking if anyone knows if there is a best practice that one should stick to when it comes to handling this distinction. References to external sources are very welcome!

    - by Chris Dixon

An OSX utility which does this is Breeze (http://autumnapps.com/breeze/ ) -- Is there a Linux equivalent?

  • Programmatically navigate to a new page

    - by [email protected]
    Did you know you can programmatically navigate to a new page via code?  Inside your bean method, you can simply use the NavigationDispatchHelper class to do the work for you. The invokePageNavigation method of NavigationDispatchHelper takes a String parameter that holds the value of the navigation rule to follow.   import oracle.adfnmc.util.NavigationDispatchHelper; public void MyBeanMethod() { /'/ Do stuff NavigationDispatchHelper.invokePageNavigation("patients"); }

  • Best way to optimize queries like this in Django

    - by chris
    I am trying to lower the amount of queries that my django app is using, but I am a little confused on how to do it. I would like to get a query set with one hit to the database and then filter items from that set. I have tried a couple of things, but I always get queries for each set. let's say I want to get all names from my DB, but also separate out the people just named Ted. Both the names and the ted set will be used in the template. This will give me two sets, one with all names and one with Ted.. but also hits the database twice: namelist = People.objects.all() tedList = namelist.filter(name='ted') Is there a way to filter the first set without hitting the data base again?

  • What are the PHP "encryption" functions?

    - by Rob
    Looking for built in encryption functions, not to hide the string from the clever programmer, but instead just to obfuscate it a bit. Looking for functions such as str_rot13 and base64_encode, but I can't seem to locate any. Surely there are more?

  • How to add a Mac to Windows Active Directory

    - by Ben Daniel
    I've gone into the Directory Utility on the mac, clicked on the services tab, entered the Active Directory Domain and Computer ID, clicked the Bind button and it showed a little status label which flickered through 5 of 5 steps and then said "An unknown error occurred". If I ignore the error and just click the OK button further down the screen and make sure the Active Directory service is ticked in the list of services, then go to the Directory Servers tab and try to add an Active Directory by entering my ad domain, computer id, admin username and password I get an error "Unable to add the domain. An unexpected error of type -14090 (eDSAuthFailed) occurred." Any ideas?

  • Equivalent of Switch Statement in MySql 5

    - by Robert Gowland
    Using MySql 5, I have a task where I need to update one table based on the contents of another table. For example, I need to add 'A1' to table 'A' if table 'B' contains 'B1'. I need to add 'A2a' and 'A2b' to table 'A' if table 'B' contains 'B2', etc.. In our case, the value in table 'B' we're interested is an enum. Right now I have a stored procedure containing a series of statements like: INSERT INTO A SELECT 'A1' FROM B WHERE B.Value = 'B1'; --Repeat for 'B2' -> 'A2a', 'A2b'; 'B3' -> 'A3', etc... Is there a nicer more DRY way of accomplishing this?
