  • How to find the only UILabel in a view and hide it?

    - by tarnfeld
    I am adding a UILabel as a subview to a UIView and sometime later I want to hide it. It is assigned to a variable but I don't think setting the variables property Hidden after it's been added to the view will work (well it doesn't seem to anyway). Is there a way to loop through the subviews in a view and then find the one that has a specific tag or is of type UILabel that I could then remove?

  • undefined method `bytes' for for String in Ruby

    - by artsince
    I am working with ruby 1.8.6 (2007-03-13 patchlevel 0) [x86_64-linux] and I get undefined method `bytes' for #<String:0x2a95ec2268> (NoMethodError) even though my code works on ruby 1.8.7. patchlevel 249 I saw somewhere that you need to add require "jcode" for a similar method not defined error with each_byte. I tried adding that but it still does not work. Any suggestions are very appreciated.

  • Drupal 7: Create a taxonomy term for each node and use the node title as the term name

    - by Spre3
    Is there anyway of doing this by using rules or by some custom code? I did try using rules but I can't find a way of adding a new term and set the name as the node title because the [node:title] token is not avilable. I know this is possible using the NAT module but the way this module changes the taxonomy terms hierarchy if you add a term reference field that uses the same taxonomy vocabulary which ruins the whole purpose of what I am trying to do.

  • ant (1.8.0/1.8.1) zip empty directories

    - by andersonbd1
    Hi, I noticed that neither the zip or jar targets are including empty directories. I googled a little and found this was a regression issue way back with 1.6 (.2 I think), but it was claimed to have been fixed. I was using 1.8.0 so I upgraded to 1.8.1, but am having the same issue. Anyone know of any workarounds besides adding dummy files to those directories? Thanks, Ben Anderson

  • iPhone SDK - options when text is selected

    - by Jack
    Hi, When text is selected in the iPhone OS, the user is given the option to copy/cut etc. How would I go about adding a new option here? An example of this is in CourseNotes for iPad http://www.youtube.com/watch?v=VLQhKkgco_I where the option is used to look up on wikipedia (around 55seconds in). Thanks

  • Reasons to store users' data in LDAP instead of RDBMS

    - by Ancymon
    It is often said that using LDAP is a good way to store data about users. That's beacause users' "directory" is hierarchical and it changes rarely. But in my opinion that doesn't exclude using RDBMS. What might be reasons to use LDAP? I guess that storing multi-valued fields or adding custom fields in LDAP might be easier but it can be done in database too (unless you have many records)

    - by Tumble
    Basically I have a Listview control which has coloums (displayed in Detail mode) I add items to it that I want displayed, each under 1 colomn (Like an invoice) but it displays them all under the first instead. I've been adding items like this below which I guess is the wrong way to do it but every other way I tried is not working. You can see he result in the screenshot. lstVLine.Items.Add(lineItem, lstVLine.Items.Count); lstVLine.Items.Add(itemName,lstVLine.Items.Count);

  • How do you make a private member in the base class become a public member in the base class?

    - by jasonline
    Consider the following code: class Base { void f() { } }; class Derived: public Base { public: }; What can you change in the derived class, such that you can perform the following: Derived d; d.f(); If the member is declared as public in the base class, adding a using declaration for Base::f in the derived class public section would've fix the problem. But if it is declared as private in the base class, this doesn't seem to work.

  • Loading from pickled data causes database error with new saves

    - by hibbie
    In order to save time moving data I pickled some models and dumped them to file. I then reloaded them into another database using the same exact model. The save worked fine and the objects kept their old id which is what I wanted. However, when saving new objects I run into nextval errors. Not being very adept with postgres, I'm not sure how to fix this so I can keep old records with their existing ID while being able to continue adding new data. Thanks, Thomas

  • constructorless initialization and Dictionaries

    - by Stacey
    Using C# 3.0, we can initialize objects without their constructors for syntactical reasons. Such as .. ClassName c = new ClassName = { Property1 = "Value" } I was wondering how this works with Dictionaries and adding the items to them. Any ideas? class Foo { public Dictionary DictionaryObject { get; set; } } Foo f = new Foo = { // ??? } Thank you for your time!!

  • Mercurial cherry picking changes for commit

    - by mansu
    Say, I made many changes to my code and only need to commit a few of those changes. Is there a way to do it in mercurial? I know that darcs has a feature like this one. I know "hg transplant" can do this between branches, but I need something like this for committing code in the present branch and not when adding change sets from some other branch.
