• With ARC why use @properties anymore?

  - by trapper

  In non-ARC code retained properties handily take care of memory management for you using the self.property = syntax, so we were taught to use them for practically everything. But now with ARC this memory management is no longer an issue, so does the reason for using properties evaporate? is there still any good reason (obviously other than providing public access to instance variables) to use properties anymore?

• SQL CASE WHEN NULL - question

  - by cc0

  Ok, so I'm trying to select an amount of rows from a column that holds the value 3, but only if there are no rows containing 10 or 4, if there are rows containing 10 or 4 I only want to show those. What would be a good syntax to do that? So far I've been attempting a CASE WHEN statement, but I can't seem to figure it out. Any help would be greatly appreciated. (My database is in an MS SQL 2008 server)

• sybase 'drop procedure'. can I get it to take a parameter instead of a naked proc name?

  - by Michael Wilson

  Happy Monday o/ I'm looking to do the following within a stored proc select @parameter="fooproc" drop procedure @parameter instead of drop procedure fooproc But it's choking with a syntax error. Is there some way I can bend this to my will? I would've expected to be able to do this. I've tried a few permutations of type declaration of @parameter to no avail. Thoughts?

• Catch all DOM events on a page (without Firebug et. al.)

  - by Morten Bergfall

  How would I go about creating a cross-browser script, that would intercept all events firing on a page/browser window/DOM-tree (regardless of browser)? What I'm hoping to accomplish is basically to get a better understanding of the different handling of events in different browsers; I know the basic theory, but need to see to believe...

• How can fill a variable of my own created data type within Oracle PL/SQL?

  - by Frankie Simon

  In Oracle I've created a data type: TABLE of VARCHAR2(200) I want to have a variable of this type within a Stored Procedure (defined locally, not as an actual table in the DB) and fill it with data. Some online samples show how I'd use my type if it was filled and passed as a parameter to the stored procedure: SELECT column_value currVal FROM table(pMyPassedParameter) However what I want is to fill it during the PL/SQL code itself, with INSERT statements. Anyone knows the syntax of this?

• Why DFS and not BFS for finding cycle in graphs.

  Predominantly DFS is used to find a cycle in graphs and not BFS. Any reasons? Both can find if a node has already been visited while traversing the tree/graph.

• C# How do I replace an actual asterisk character (*) in a Regex expression?

  - by fraXis

  Hello, I have a statement: I have a string such as content = "* test *" I want to search and replace it with so when I am done the string contains this: content = "(*) test (*)" My code is: content = Regex.Replace(content, "*", "(*)"); But this causes an error in C# because it thinks that the * is part of the Regular Expressions Syntax. How can I modify this code so it changes all asterisks in my string to (*) instead without causing a runtime error? Thanks.

• Should I invest time in learning Java language these days? (question from a greenhorn)

  - by dave-keiture

  Hi experts, Assuming you've already had a chance to look through the lambda syntax proposed for Java7 (and the other things that have happened with Java, after Oracle has bought Sun + obvious problems in Java Community Process), what do you think is the future of Java language? Should I, as a Java greenhorn, invest time in learning Java language (not talking about the core JVM, which definitely will survive anything, and worth investments), or concentrate on Scala, Groovy, or other hybrid languages on the JVM platform (I've came into Java world from PHP/Ruby). Thanks in advance.

• Python: Split, strip, and join in one line

  - by PandemoniumSyndicate

  I'm curious if their is some python magic I may not know to accomplish a bit of frivolity given the line: csvData.append(','.join([line.split(":").strip() for x in L])) I'm attempting to split a line on :, trim whitespace around it, and join on , problem is, since the array is returned from line.split(":"), the for x in L #<== L doesn't exist! causes issues since I have no name for the array returned by line.split(":") So I'm curious if there is a sexy piece of syntax I could use to accomplish this in one shot? Cheers!

• How to change aif to be able to access 'it' within the macrocall without making 'it' public in the package

  - by Sim

  If you put the aif code presented in onlisp in a package and try to use it in another you run in the problem that packagename:it is not external. (in-package :packagename) (defmacro aif (test-form then-form &optional else-form) ‘(let ((it ,test-form)) (if it ,then-form ,else-form))) wanted call syntax (in-package :otherpackage) (aif (do-stuff) (FORMAT t "~a~%" it) (FORMAT t "just got nil~%")) How can I fix this behavior in code, without making the variable it external in the package declaration and beeing able to access it just by it instead of packagename:it?

• Can I create a file that sits next to a .Designer.cs file in Visual Studio?

  - by Ian Potter

  In Visual Studio, two files are created when you create a new Windows Form in your solution (e.g. if you create MyForm.cs, MyForm.Designer.cs and MyForm.resx are also created). These second two files are displayed as a subtree in the Solution Explorer. Is there any way to add files to the sub-tree or group for a Windows Form class?

• What does the caret mean in C++/CLI?

  I just came across this code and a few Google searches turn up no explanation of this mysterious (to me) syntax. Hashtable^ tempHash = gcnew Hashtable(iterators_); IDictionaryEnumerator^ enumerator = tempHash->GetEnumerator(); What the heck does the caret mean? (The gcnew is also new to me, and I asked about that here.)
