  • Should I use ICommand or Expression.Interactions InvokeCommand for MVVM in Silverlight 4?

    - by phejndorf
    I'm about to embark on a new project in Silverlight 4, and definitely want to take advantage of the MVVM pattern, now I've finally grasped the basics. For implementing commands in Silverlight 4 it seems there are rather a lot of options ranging from the new built-in Command/ICommand option on the Button, over the InvokeCommand defined in the Microsoft.Expressions.Interactivity namespace and on to the range of assisting MVVM frameworks (Prism, MVVMlight etc). Does anyone here have gotcha's, experience and wisdom to share on this subject?

  • Are there any way to apply regexp in java ignoring letter case?

    - by Roman
    Simple example: we have string "Some sample string Of Text". And I want to filter out all stop words (i.e. "some" and "of") but I don't want to change letter case of other words which should be retained. If letter case was unimportant I would do this: str.toLowerCase().replaceAll ("a|the|of|some|any", ""); Is there an "ignore case" solution with regular expressions in java?

Probably with Expressions. private void RegisterEvent(EventHandler handler, Action<EventArgs> action) { handler += action; m_toUnsubscribe.Add(handler, action); } ... in Dispose() { foreach(var pair in m_toUnsubscribe) { pair.handler -= pair.action; } }

  • JSF action, value and binding catalog generator

    - by BBSnowman
    I am looking for a simple tool that generates a catalog of all used action methods, values and bindings. I'm working on a big JSF/RichFaces project and I have lost the overview of the used links to the beans. Therefore I need a tool (would be nice if it is a Eclipse plugin) that generates a simple list of all used EL expressions. Is there something out there?

  • Good advanced book on developing robust C# modules

    - by AlexKuznetsov
    I have some experience with C#, and would like to improve my knowledge of its latest improvements. I am in the middle of reading and enjoying "Effective C#" by Bill Wagner right now. However, I would appreciate more examples, especially with lambda expressions and such. Any suggestions are greatly appreciated. High quality resources are preferable, and it does not matter much if they are free or not.

  • How do I escape backslashes in JSON?

    - by peteb
    I am using Firefox's native JSON.parse() to parse some JSON strings that include regular expressions as values, for example: var test = JSON.parse('{"regex":"/\\d+/"}'); The '\d' in the above throws an exception with JSON.parse(), but works fine when I use eval (which is what I'm trying to avoid). What I want is to preserve the '\' in the regex - is there some other JSON-friendly way to escape it?

  • Python PLY zero or more occurrences of a parsing item

    - by None
    I am using Python with PLY to parse LISP-like S-Expressions and when parsing a function call there can be zero or more arguments. How can I put this into the yacc code. This is my function so far: def p_EXPR(p): '''EXPR : NUMBER | STRING | LPAREN funcname [EXPR] RPAREN''' if len(p) == 2: p[0] = p[1] else: p[0] = ("Call", p[2], p[3:-1]) I need to replace "[EXPR]" with something that allows zero or more EXPR's. How can I do this?

  • gcc check if file is main (#if __BASE_FILE__ == __FILE__)

    - by Marcin Raczkowski
    Hello. In ruby there's very common idiom to check if current file is "main" file: if __FILE__ == $0 # do something here (usually run unit tests) end I'd like to do something similar in C after reading gcc documentation I've figured that it should work like this: #if __FILE__ == __BASE_FILE__ // Do stuff #endif the only problem is after I try this: $ gcc src/bitmap_index.c -std=c99 -lm && ./a.out src/bitmap_index.c:173:1: error: token ""src/bitmap_index.c"" is not valid in preprocessor expressions Am I using #if wrong?

  • Why are member constants available even if there are no instances of a its class?

    - by flockofcode
    1) Why are member constants available even if there are no instances of a its class? 2) Is the only reason why constant expressions need to be fully evaluated at compile time due to compiler replacing constant variable with literal value? 3) Since string is also an object, I would think the following would produce an error, but it doesn’t. Why? class A { const string b = “it works”; } thank you

  • PL/SQL REGEXP_LIKE testing string for allowed characters

    - by Arino
    I need to verify that the provided string has only allowed characters using Oracle regular expressions (REGEXP_LIKE). Allowed chars are: abcdefghijklmnopqrstuvwxyz0123456789_-. Trying to execute SELECT CASE WHEN REGEXP_LIKE('abcdefghijklmnopqrstuvwxyz0123456789_-.' , '^[a-z0-9_\-\.]+$') THEN 'true' ELSE 'false' END tmp FROM dual; results in 'false'. Any ideas on this?

  • android get URL path

    - by Tom91136
    I've got a string: public://imageifarm/3600.jpg How can I extract the imageifarm/3600.jpg Part out using android? What I've tried so far: URL drupalQuestionNodeImageURI = new URL("public://imageifarm/3600.jpg"); Log.d("TAG", drupalQuestionNodeImageURI.getPath()); but it throws this exception: 09-16 17:24:39.992: W/System.err(3763): java.net.MalformedURLException: Unknown protocol: public How can I solve this? I know I can use regular expressions but that seems to defeat the purpose of URL(URI) in this case.

  • PHP: Is_numeric returns false on 0

    - by Industrial
    Hi everyone, Is_numeric() as well as is_int() returns false if the value is 0. What can i do instead to verify that a specific value is numbers only in PHP? Are we heading straight for the Regular Expressions camp, or are there some nice, handy feature for this out there already? Thanks!

  • Python - Find where in string regex match was found?

    - by nb
    I'm currently using regular expressions to search through RSS feeds to find if certain words and phrases are mentioned, and would then like to extract the text on either side of the match as well. For example: String = "This is an example sentence, it is for demonstration only" re.search("is", String) I'd like to know where the is was found so that I can extract and output something like this: 1 match found: "This is an example sentence" I know that it would be easy to do with splits, but I'd need to know what the index of first character of the match was in the string, which I don't know how to find
