• Cache Wrapper with expressions

  - by Fujiy

  I dont know if is possible. I want a class to encapsulate all Cache of my site. I thinking about the best way to do this to avoid conflict with keys. My first idea is something like this: public static TResult Cachear<TResult>(this Cache cache, Expression<Func<TResult>> funcao) { string chave = funcao.ToString(); if (!(cache[chave] is TResult)) { cache[chave] = funcao.Compile()(); } return (TResult)cache[chave]; } Is the best way?

• dynamic behavior of factory class

  - by manu1001

  I have a factory class that serves out a bunch of properties. Now, the properties might come either from a database or from a properties file. This is what I've come up with. public class Factory { private static final INSTANCE = new Factory(source); private Factory(DbSource source) { // read from db, save properties } private Factory(FileSource source) { // read from file, save properties } // getInstance() and getProperties() here } What's a clean way of switching between these behaviors based on the environment. I want to avoid having to recompile the class each time.

• Syntax to specify Namespace when using helper.RouteUrl

  - by B Z

  I am using Asp.Net MVC 2 - RC w/ Areas. I am receiving an ambigious controller name exception due to having same controller name in two different areas. I've read Phil Haack's post I can't figure out the syntax when trying to use UrlHelper (I have an extensions class). e.g. public static string MyAreaHome(this UrlHelper helper) { return helper.RouteUrl("ARoute", new { controller = "Home", action = "Index" }); } I've tried the obvious of adding namespace="mynamespace" but that didn't work, it just added the namespace to the url. Thanks for any help.

• Why doesn't this loop terminate?

  - by David

  Here's the sample code: public static void col (int n) { if (n % 2 == 0) n = n/2 ; if (n % 2 != 0) n = ((n*3)+1) ; System.out.println (n) ; if (n != 1) col (n) ; } this works just fine until it gets down to 2. then it outputs 2 4 2 4 2 4 2 4 2 4 infinitely. it seems to me that if 2 is entered as n then (n % 2 == 0) is true 2 will be divided by 2 to yeild 1. then 1 will be printed and since (n != 1) is false the loop will terminate. Why doesn't this happen?

• How to preserve whitespace indentation of text enclosed in HTML <pre> tags excluding the current indentation level of the <pre> tag in the document?

  - by Michael Barton

  I'm trying to display my code on a website but I'm having problems preserving the whitespace indentation correctly. For instance given the following snippet: <html> <body> Here is my code: <pre> def some_funtion return 'Hello, World!' end </pre> <body> </html> This is displayed in the browser as: Here is my code: def some_funtion return 'Hello, World!' end When I would like it displayed as: Here is my code: def some_funtion return 'Hello, World!' end The difference is that that current indentation level of the HTML pre tag is being added to the indentation of the code. I'm using nanoc as a static website generator and I'm using google prettify to also add syntax highlighting. Can anyone offer any suggestions?

• File private variables in PHP

  - by kayahr

  Is it possible to define private variables in a PHP script so these variables are only visible in this single PHP script and nowhere else? I want to have an include file which does something without polluting the global namespace. It must work with PHP 5.2 so PHP namespaces are not an option. And no OOP is used here so I'm not searching for private class members. I'm searching for "somewhat-global" variables which are global in the current script but nowhere else. In C I could do it with the static keyword but is there something similar in PHP? Here is a short example of a "common.php" script: $dir = dirname(__FILE__); set_include_path($dir . PATH_SEPARATOR . get_include_path()); // Do more stuff with the $dir variable When I include this file in some script then the $dir variable is visible in all other scripts as well and I don't want that. So how can I prevent this?

• Import boto from local library

  - by ensnare

  I'm trying to use boto as a downloaded library, rather than installing it globally on my machine. I'm able to import boto, but when I run boto.connect_dynamodb() I get an error: ImportError: No module named dynamodb.layer2 Here's my file structure: project/ project/ __init__.py libraries/ __init__.py flask/ boto/ views/ .... modules/ __init__.py db.py .... templates/ .... static/ .... runserver.py And the contents of the relevant files as follows: project/project/modules/db.py from project.libraries import boto conn = boto.connect_dynamodb( aws_access_key_id='<YOUR_AWS_KEY_ID>', aws_secret_access_key='<YOUR_AWS_SECRET_KEY>') What am I doing wrong? Thanks in advance.

• I have Person.Surname field implemented as a string if I change the implementation of the field to a

  - by AndyM

  This is me going right back to basics with TDD for learning purposes. I originally implemented Person.Surname as field of type object (the simplest possible way of passing the test. I then added a test setting Person.Surname stating that the return value should be a string and set Person.Surname=20. I 'fixed' the test by changing the implementation to use string rather than object. The test now long compiles due to static type checking, so I commented it out. So I'm left with no way of leaving my intention in the test. Is there a way of having a failing test in this circumstance?

• Copy Rows in a One to Many with LINQ (2 SQL)

  - by Refracted Paladin

  I have a table that stores a bunch of diagnosis for a single plan. When the users create a new plan I need to copy over all existing diagnosis's as well. I had thought to try the below but this is obviously not correct. I am guessing that I will need to loop through my oldDiagnosis part, but how? Thanks! My Attempt so far... public static void CopyPlanDiagnosis(int newPlanID, int oldPlanID) { using (var context = McpDataContext.Create()) { var oldDiagnosis = from planDiagnosi in context.tblPlanDiagnosis where planDiagnosi.PlanID == oldPlanID select planDiagnosi; var newDiagnosis = new tblPlanDiagnosi { PlanID = newPlanID, DiagnosisCueID = oldDiagnosis.DiagnosisCueID, DiagnosisOther = oldDiagnosis.DiagnosisOther, AdditionalInfo = oldDiagnosis.AdditionalInfo, rowguid = Guid.NewGuid() }; context.tblPlanDiagnosis.InsertOnSubmit(newDiagnosis); context.SubmitChanges(); } }

• C++ this as thread parameter, variables unavailable

  - by brecht

  I have three classes: class Rtss_Generator { int mv_transfersize; } class Rtss_GenSine : Rtss_Generator class Rtss_GenSineRpm : Rtss_GenSine Rtss_GenSine creates a thread in his constructer, it is started immediatly and the threadfunction is off-course declared static, waiting for an event to start calculating. the problem: all the variables that are accessed through the gen-pointer are 0, but it does not fail. Also, this-address in the constructer and the gen-pointer-address in the thread are the same, so the pointer is ok. this code is created and compile in visual studio 6.0 service pack 2003 ORIGINAL CODE no thread Rtss_GenSine::getNextData() { //[CALCULATION] //mv_transferSize is accessible and has ALWAYS value 1600 which is ok } NEW CODE Rtss_GenSine::Rtss_GenSine() { createThread(NULL, threadFunction, (LPVOID) this,0,0); } Rtss_GenSine::getNextData() { SetEvent(startCalculating); WaitForSingleObject(stoppedCalculaing, INFINITE); } DWORD Rtss_GenSine::threadFunction(LPVOID pParam) { Rtss_GenSine* gen = (Rtss_GenSine*) pParam; while(runThread) { WaitForSingleObject(startCalculating, INFINITE); ResetEvent(startCalculating) //[CALCULATION] //gen->mv_transferSize ---> it does not fail, but is always zero //all variables accessed via the gen-pointer are 0 setEvent(stoppedCalculaing) } }

• Making element draggable with Android WebView (ideally, just with Javascript) ?

  - by GJTorikian

  I'm building an app with a build target of 1.5 . I have a variable, WebView browser, that is calling loadUrl to load a static HTML page from my assets folder. In that HTML page, the following JavaScript is defined: var supportsTouch = ('createTouch' in document); ... var w = $('wrapper'); w[supportsTouch ? 'touchmove' : 'onmousemove'] = move; w[supportsTouch ? 'touchend' : 'onmouseup'] = function(event){ dragging = false; }; where move is another function that handles the dragging. Unfortunately, this doesn't seem to work. I cannot figure out a concise list of which touch events are available to Android--is it ontouchmove, or touchmove? Am I supposed to set up an onTouchEvent call back in my Java code, which then launches the JavaScript function?

• Using Api to submit userdata to external party

  - by Younes

  I have to submit subscription data to another website. I have got documentation on how to use this API however i'm not 100% sure of how to set this up. I do have all the information needed, like username / passwords etc. This is the API documentation: https://www.apiemail.net/api/documentation/?SID=4 How would my request / post / whatever look like in C# .net (vs 2008) when i'm trying to acces this API? This is what i have now, I think i'm not on the right track: public static string GArequestResponseHelper(string url, string token, string username, string password) { HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url); myRequest.Headers.Add("Username: " + username); myRequest.Headers.Add("Password: " + password); HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse(); Stream responseBody = myResponse.GetResponseStream(); Encoding encode = System.Text.Encoding.GetEncoding("utf-8"); StreamReader readStream = new StreamReader(responseBody, encode); //return string itself (easier to work with) return readStream.ReadToEnd();

• Why does the data binding in this validation example work?

  - by MartyIX

  I'm wondering how exactly the XAML sample (MSDN sample) works: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Questions: (Validation.Errors)[0].ErrorContent - Is this code somehow checked by WPF? Because Validation.Errors may be an empty collection and in ordinary C# code this code may throw an exception. If this data-binding returns null for valid input - the null value is then casted to empty string (in a text control for example)? The index 0 corresponds to the first error message. How can I return more error messages from Validate method? Thank you for responses!

• WPF window scrolling with top menu

  - by Greg R

  I'm running into a dilemma. When I make the ScrollViewer the main content object of my window, scrolling behaves exactly like I want it to. You resize to make it smaller than the content and the window and scroll bars appear. The problem comes in when I want the to menu to be static and the rest of content to be scrollable. I want the scroll bars to behave the same way as a browser window does, meaning when you resize it, the scroll bars appear based on the size of the content. When you expand the window, the content takes up the entire real estate of the window. Is that possible in WPF? Help would be GREATLY appreciated.

• What's the smartest way to organize SVN for translated versions of the same project?

  - by brandonjp

  I apologize because I know this has been covered over and over again, but I'm trying to understand the smartest way to cleverly use subversion to our benefit. (*Note: I know our method is not the BEST way to handle localized versions, but external factors are forcing us to work this way on current projects) We have a fairly static website in English...html, css, js, etc. After the site comes back from the translator we will have 5 variations of the same code (this week...then potentially 25 more in the future!). So we'll soon have a folder for EN, FR, SP, DE, etc. Most files (css, js, img) will remain exactly the same; and html files (structure, id's, classes) will only vary based on the localized text inside the elements. Is there any way to use clever SVN folder structuring that would help us out in the event that if a small change is needed, we don't have to manually change the files in each and every translated version of the site? Thanks! --bp

• Count the number of lines in a Java String

  - by Simon Guo

  Need some compact code for counting the number of lines in a string in Java. The string is to be separated by \r or \n. Each instance of those newline characters will be considered as a separate line. For example, "Hello\nWorld\nThis\nIs\t" should return 4. The prototype is private static int countLines(String str) {...} Can someone provide a compact set of statements? I have solution at here but it is too long, I think. Thank you.

• Changing a limited user account in XP fails

  - by javamonkey79

  I have the following: using System; using System.DirectoryServices.AccountManagement; public class ChangePassword { public static void Main() { PrincipalContext context = new PrincipalContext(ContextType.Machine); UserPrincipal user = UserPrincipal.FindByIdentity(context, "someLimitedAccount"); user.ChangePassword( "xxx", "zzz" ); } } This works just fine with administrator accounts, but seems to crash like so when I try to change limited accounts in XP: Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at ChangePassword.Main() Is what I am trying to do possible? If so, how? EDIT #1: I added the following: Console.WriteLine( "user: " + user ); Below this line: UserPrincipal user = UserPrincipal.FindByIdentity(context, "someLimitedAccount"); And I get this: user: It doesn't look like user is null when I print it, but then again I'm not really a .Net guy - I seem to remember this being expected behavior.

• logging in scala

  - by IttayD

  In Java, the standard idiom for logging is to create a static variable for a logger object and use that in the various methods. In Scala, it looks like the idiom is to create a Logging trait with a logger member and mixin the trait in concrete classes. This means that each time an object is created it calls the logging framework to get a logger and also the object is bigger due to the additional reference. Is there an alternative that allows the ease of use of "with Logging" while still using a per-class logger instance? EDIT: My question is not about how one can write a logging framework in Scala, but rather how to use an existing one (log4j) without incurring an overhead of performance (getting a reference for each instance) or code complexity. Also, yes, I want to use log4j, simply because I'll use 3rd party libraries written in Java that are likely to use log4j.
