• .NET MVC Code Generation

  - by Josh

  Is there a way to force the MVC automatically generated code to follow the conventions you have set in your preferences? For example, I keep all curly braces on the same lines as their declaring class, method, etc, but when generating a controller, it completely disregards my settings. Is there a setting someplace to force the same code generation as other parts of project?

• Poor performance / speed of regex with lookahead

  - by Hugo Zaragoza

  I have been observing extremely slow execution times with expressions with several lookaheads. I suppose that this is due to underlying data structures, but it seems pretty extreme and I wonder if I do something wrong or if there are known work-arounds. The problem is determining if a set of words are present in a string, in any order. For example we want to find out if two terms "term1" AND "term2" are somewhere in a string. I do this with the expresion: (?=.*\bterm1\b)(?=.*\bterm2\b) But what I observe is that this is an order of magnitude slower than checking first just \bterm1\b and just then \bterm2\b This seems to indicate that I should use an array of patterns instead of a single pattern with lookaheads... is this right? it seems wrong... Here is an example test code and resulting times: public static void speedLookAhead() { Matcher m, m1, m2; boolean find; int its = 1000000; // create long non-matching string char[] str = new char[2000]; for (int i = 0; i < str.length; i++) { str[i] = 'x'; } String test = str.toString(); // First method: use one expression with lookaheads m = Pattern.compile("(?=.*\\bterm1\\b)(?=.*\\bterm2\\b)").matcher(test); long time = System.currentTimeMillis(); ; for (int i = 0; i < its; i++) { m.reset(test); find = m.find(); } time = System.currentTimeMillis() - time; System.out.println(time); // Second method: use two expressions and AND the results m1 = Pattern.compile("\\bterm1\\b").matcher(test); m2 = Pattern.compile("\\bterm2\\b").matcher(test); time = System.currentTimeMillis(); ; for (int i = 0; i < its; i++) { m1.reset(test); m2.reset(test); find = m1.find() && m2.find(); } time = System.currentTimeMillis() - time; System.out.println(time); } This outputs in my computer: 1754 150

• .NET read binary contents of .lnk file

  - by Flores

  I want to read the binary contents of a .lnk file. As long as the target of the shortcut (lnk file) exists this works fine with IO.File.ReadAllBytes(string file). BUT If the target of the shortcut does not exist (believe me I want this) the method only returns zero's. I guess this is because the OS follows the link and if it does not exist it returns zero's Is there some way to bypass the fact that the framework follows the target of the .lnk before displaying the contents of the .lnk file?

• I need to encrypt the names of my http form elements

  - by William Calleja

  I have a form with certain elements, input boxes, check boxes etc. I need to encrypt the names of these input boxes and check boxes. I'm currently using a Rijndael encryption/decryption method through c# however this is making the encrypted names too long to be passed in a post. Is there a better way to get decent encrypted names? my purpose is to have the names encrypted before the post happens so if someone views the code behind the names are already encrypted.
