I use SimpleShareMem Unit to pass strings but also tried ShareMem with borlndmm.dll. For one function i now pass a string from the Delphi 2007 programm to the dll (Therefore An...
Displaying a string while using cond in Lisp
Hi, I'm just starting off with Lisp and need some help. This is technically homework, but I gave it a try and am getting somewhat what I wanted: (defun speed (kmp) (cond ((> kmp 100) "Fast") ((< kmp 40) "Slow") (t "Average"))) However, if I run the program it displays "Average" instead of just Ave...
What is equivalent in JavaScript to C#'s @ language feature for ignoring escape chars in string literals?
I think this question may be fairly evident from the title alone: I am a C# developer who often uses @ before a string literal to make it more readable (e.g. string drive = @"C:\") I am in the process of scripting out a lot of my processes (using the wonderful V8 for .Net) and I am wondering whether there's a similar feature in JavaScri...

Suggestions to improve a C ReplaceString function?
Hi, I've just started to get in to C programming and would appreciate criticism on my ReplaceString function. It seems pretty fast (it doesn't allocate any memory other than one malloc for the result string) but it seems awfully verbose and I know it could be done better. Example usage: printf("New string: %s\n", ReplaceString("great",...

Passing const char* as template argument
Why can't you pass literal strings in here? I made it work with a very slight workaround. template<const char* ptr> struct lols { lols() : i(ptr) {} std::string i; }; class file { public: static const char arg[]; }; decltype(file::arg) file::arg = __FILE__; // Getting the right type declaration for this was irritating, so I ...
PHP - add/remove carriage returns to a base 64 encoded string

The problem is that this string doesn't have any spaces or carriage returns so it gets displayed on one line with a ugly horizontal scroll bar.

Shortest way to break-up long string (add whitespace) after 60 chars?
