So they input something like: Email body text including <. (say ExistingVariable is an int or something like that) Any helpful hints for how to convert this text with a ToString() at runtime?

• Is it alright to call len() in a loop's conditional statement?

  - by DormoTheNord

  In C, it is considered bad practice to call strlen like this: for ( i = 0; strlen ( str ) != foo; i++ ) { // stuff } The reason, of course, is that it is inefficient since it "counts" the characters in a string multiple times. However, in Python, I see code like this quite often: for i in range ( 0, len ( list ) ): # stuff Is this bad practice? Should I store the result of len() in a variable and use that?

  I am curious to know if there is a way to edit code in VS 2008 right when it has hit a breakpoint and I am walking thru the code... can I modify the code (such as the value in a variable or if my stepthrough line is about to hit an if statement ... can I modify the if statement....etc)?

• Workflow for reading and writing files

  - by AIR_PhillipSenn

  In Workflow for reading and writing files the authors use these two lines of code: var file = air.File.documentsDirectory; file = file.resolvePath("AIR Test/testFile.txt"); But I think that it's using one variable for two different meanings, isn't it? Wouldn't it be better to write them as: var myDocumentsDirectory = air.File.documentsDirectory; var myTestFile = myDocumentsDirectory.resolvePath("AIR Test/testFile.txt");

• Answered: Selecting even table rows from a table element

  - by mvrak

  The issue I am having is: How do I go from a variable pointing at an element to using CSS selectors? I want to make this work: function highlight(table) {$(table " > :even").toggleClass('highlight');} where table is a reference to a table element. I don't want answers that tell me to use $('#table') because that defeats the point of the generality I am trying to make. Thanks

• Syntax proposition: readability of templated type declarations

  - by Knowing me knowing you

  I wonder if syntax as follows would be helpful in your opinion as a code readability improvent and self-commenting of code: std::map<std::string name, std::vector<int> scores> myMap; In this example it clearly says and no other comment is needed, what for we are using myMap variable. Looking forward to your opinions.

  - by John Topley

  Could somebody please explain why the variable named foo remains true in the code below, even though it's set to false when the method is called? And why the symbol version behaves as expected? def test(options = {}) foo = options[:foo] || true bar = options[:bar] || :true puts "foo is #{foo}, bar is #{bar}" end >> test(:foo => false, :bar => :false) foo is true, bar is false I've only tried this using Ruby 1.8.7.
