• How can I manually interpolate string escapes in a Perl string?

  - by Ryan Thompson

  In perl suppose I have a string like 'hello\tworld\n', and what I want is: 'hello world ' That is, "hello", then a literal tab character, then "world", then a literal newline. Or equivalently, "hello\tworld\n" (note the double quotes). In other words, is there a function for taking a string with escape sequences and returning an equivalent string with all the escape sequences interpolated?

• Extending Visual Studio with a Custom Designer

  - by Mick

  How do I create a custom Visual Studio 2008 UI designer for a C# file? For example, when you double click on a DataSet in the Solution Explorer, a UI screen appears that allows you to edit the DataSet, even though it is defined in XML/code (which you can right click and "View Code"). Usually this code is separated from user code in some way, either by region ("Windows Forms Designer Generated Code"), by codegen (".g.cs" for WPF XAML files), or some other means like partial classes.

• Cocoa equivalent of diskEvt/kEventClassVolume?

  - by tewha

  We have a drop-down menu of volumes in our UI, and I'd like to update it when a new disk is mounted. In the Classic days, this would involve watching for a diskEvt event. In Carbon, I think this was kEventClassVolume. What's the Cocoa equivalent? (A pointer into Apple's documentation on this would satisfy the question. I've been unable to find anything!)

• Help with \0 terminated strings in C#

  - by Joshua

  I'm using a low level native API where I send an unsafe byte buffer pointer to get a c-string value. So it gives me // using byte[255] c_str string s = new string(Encoding.ASCII.GetChars(c_str)); // now s == "heresastring\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0(etc)"; So obviously I'm not doing it right, how I get rid of the excess?

• Lisp: Determine if a list contains a predicate

  - by justkt

  As part of a homework assignment in Lisp, I am to use apply or funcall on any predicates I find. My question (uncovered in the coursework) is: how do I know when I've found a predicate in my list of arguments? I've done some basic google searching and come up with nothing so far. We're allowed to use Lisp references for the assignment - even a pointer to a good online resource (and perhaps a specific page within one) would be great!
