• resolving localhost in php so can be views outside VM

  - by DA

  I'm running Windows 7. Within, I'm running Virtualbox and Ubuntu. Within Ubuntu, I'm running Apache and using PHP codeigniter. To reference our CSS and JS files, we use this syntax: <?php echo site_url('css/styles.css'); ?> When viewing the site locally (within Ubuntu VM) that resolves to: http://localhost/styles.css So works fine. The catch is when I access that site from within Windows 7 (for IE testing). To access the site in Windows 7, I refer to the IP address of the VM: http://xx.x.x.x/ That loads the site but, alas, all the site_url variables are still being rewritten as 'localhost'. Said files obviously don't exist on the localhost of my windows 7. Is there a way around this short of just hard-coding relative links in my PHP file?

• JAVA: How to use paint() method to update the previously drawn object?

  - by GamDroid

  How to use paint() such that when repaint() is called the previously drawn object should not get deleted when drawing the new object. That is the drawing area must get UPDATED only and not REDRAWN. In my code when one of many button is clicked, some aplhabet get displayed. I want to have functionality such that when other buttons are clicked the previously drawn alhabets must be present.Take is as if a string of alphabets getting created as the buttons are clicked. Im using Java Swing for coding. Some piece of my code: if(source == btnAlpha[i] ) bollyDraw.repaint(); //bollydraw is an object of a JPanel extended class having implemented the paintComponent(Graphics g) method In the paint() method: if (word[i] == key) { g.drawChars(word, i, 1, x, y); }

• Java: Local Enums

  - by bruno conde

  Today, I found myself coding something like this ... public class LocalEnums { public LocalEnums() { } public void foo() { enum LocalEnum { A,B,C }; // .... // class LocalClass { } } } and I was kind of surprised when the compiler reported an error on the local enum: The member enum LocalEnum cannot be local Why can't enums be declared local like classes? I found this very useful in certain situations. In the case I was working, the rest of the code didn't need to know anything about the enum. Is there any structural/design conflict that explains why this is not possible or could this be a future feature of Java?

• Database connection management in Spring

  - by ria

  Do we have to explicitly manage database resources when using Spring Framework.. liking closing all open connections etc? I have read that Spring relieves developer from such boiler plate coding... This is to answer an error that I am getting in a Spring web app: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: ORA-00020: maximum number of processes (150) exceeded The jdbcTemplate is configured in the xml file and the DAO implementation has reference to this jdbcTemplate bean which is used to query the database.

• Any good books out there for advanced concepts like lambdas, delegates, events etc?

  - by they_soft

  I've read about these features but I don't think I've seen enough to consistently apply them in my coding, eg "This would be better done with a delegate than with my other, outdated approach". I know what they do, but I want more examples of use cases, or want some heuristic to help me think in terms of such features. All the books I've seen either focus only on the basics or just mention the features as part of the language. Is there any book out there that deals with this? Preferably C# or language agnostic.

• TypeInitilazationException When Getting an NHibernate Session

  - by Paul Johnson

  I’ve run into what appears to be an NHibernate config problem. Basically, I ran up a simple proof of concept persistence integration test using NUnit, the test simply querys an Oracle database and successfully returns the last record received by the underlying table. However, when the assemblies are taken out of the NUnit test environment and deployed as they would be for an actual application build, my call for an NHibernate session results in a ‘TypeInitializationException’ whilst executing the code line: sessionFactory = New Configuration().Configure().BuildSessionFactory() The application is a vb.net console app running against an Oracle 9.2 database, using a ‘coding framework’ published on the web by Bill McCafferty entitled 'NHibernate Best Practices with ASP.NET' (pre S#harp Architecture). I am running version 2.1.2.4000 of NHibernate. Any assistance much appreciated. Kind Regards Paul J.

• SQL "JOIN" vs. "INNER JOIN"?

  - by froadie

  I recently came across a query that implements a join using just the "JOIN" keyword. On researching I saw that when using a join in SQL without specifying INNER or OUTER, the default is an INNER JOIN. I've never come across this syntax before; all the SQL I've written/read/worked with specifies INNER or some sort of OUTER (LEFT, RIGHT, FULL...). Is there any reason not to rely on the default? Is the plain JOIN widely used? What are the coding standards regarding JOIN vs. INNER JOIN?

• cannot output a json encoded dict containing accents (noob inside)

  - by user296546

  Hi all, here is a fairly simple example wich is driving me nuts since a couple of days. Considering the following script: # -*- coding: utf-8 -* from json import dumps as json_dumps machaine = u"une personne émérite" print(machaine) output = {} output[1] = machaine jsonoutput = json_dumps(output) print(jsonoutput) The result of this from cli: une personne émérite {"1": "une personne \u00e9m\u00e9rite"} I don't understand why their such a difference between the two strings. i have been trying all sorts of encode, decode etc but i can't seem to be able to find the right way to do it. Does anybody has an idea ? Thanks in advance. Matthieu

• As our favorite imperative languages gain functional constructs, should loops be considered a code s

  - by Michael Buen

  In allusion to Dare Obasanjo's impressions on Map, Reduce, Filter (Functional Programming in C# 3.0: How Map/Reduce/Filter can Rock your World) "With these three building blocks, you could replace the majority of the procedural for loops in your application with a single line of code. C# 3.0 doesn't just stop there." Should we increasingly use them instead of loops? And should be having loops(instead of those three building blocks of data manipulation) be one of the metrics for coding horrors on code reviews? And why? [NOTE] I'm not advocating fully functional programming on those codes that could be simply translated to loops(e.g. tail recursions) Asking for politer term. Considering that the phrase "code smell" is not so diplomatic, I posted another question http://stackoverflow.com/questions/432492/whats-the-politer-word-for-code-smell about the right word for "code smell", er.. utterly bad code. Should that phrase have a place in our programming parlance?

• adldap class, need to search for user in two groups

  - by Brad

  http://adldap.sourceforge.net/wiki/doku.php?id=api_user_functions#user_ingroup_username_group_recursive_null I am using the adLDAP class above to authenticate users against our ldap server. I was wondering how I could check multiple groups to see if the user belongs to either, if they belong to either. I don't know if user_ingroup($username,$group,$recursive=NULL); can handle search two different groups for the user, need help coding it to search for the user in two different groups, and as soon as it finds it in one of those, break the operation and set a variable to true. Any help is appreciated.

• Matlab tutorial for programmers

  - by Jonas

  I'm getting some new students soon, who will be writing Matlab code. They're new to Matlab, but they have experience coding in Java and C++. I'm going to have them go through the 'Getting Started' section of the Matlab help. In addition, I want to give a small tutorial with the goal to prevent them from making some of the most common mistakes people make when switching to Matlab ("Matlab starts counting at 1"), and show them some features that they may not be aware of when coming from other languages ("you can subtract a scalar directly from an array, and for vectors, there's bsxfun"). What are the most important things I should tell them?

• AS3 TextField - unwanted carriage return when setting value to ""

  - by jevinkones

  I have an input TextField and have a KeyboardEvent.KEY_DOWN even listener on the stage to listen for the Keyboard.ENTER event. The event listener adds the entered text to an array or whatever, and then clears the TextField. The problem is that when the Enter key event fires and the TextField value is set to "", it leaves a carriage return in the TextField and the cursor positioned on the second line. WTF? I've been coding AS2 and AS3 for a LONG time and have never ran into this before. Am I losing my mind? Please help, people! :-) Example: var myTextArray:Array = new Array(); stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown); function onKeyDown(e:KeyboardEvent):void{ if(e.keyCode == Keyboard.ENTER){ if(_inputText.text != null){ myTextArray.push(_inputText.text); } _inputText.text = ""; } }

• What next in the career map for a Lead QA Engineer

  - by chandran

  I am a Lead QA Engineer in a Software company and at a stage in my career wherein i need to plan my next move. Option 1: The very obvious move would be to stay as a QA Lead and eventually become a QA Manager. But i don't see very good prospects/future after that. Or am i wrong? Option 2: I love programming/coding, though i haven't spent a whole lot of time on that. So a direct move to becoming a Software Developer is not possible. Will moving to Test Automation eventually lead me to development. Even so, am i looking at step-down in pay and career-level. Option 3: Moving to Product Management. Is this even possible and if so what would be the best approach. Appreciate all your responses in advance. Thanks.

• SharePoint Permissions

  - by Greg

  I have a custom workflow. This workflow removes permissions to items when an item is added (example an item is added by a service account and once added those permissions need to be removed from that item). This works as I have the service account 'hard coded' in the custom workflow. Now I would like to remove this hard coding and when a item is added to a list I would like to iterate through all users that have access to the list item. If a user matches some algorithm then remove that user from the item permissions which will be 0 to many. The piece I'm stuggling with is how to iterage all users with permission to a SPListItem. Any thoughts on how to accomplish this? Thanks in advance!

• foreach loop from multiple arrays c#

  - by Mike

  This should be a simple question. All I want to know is if there is a better way of coding this. I want to do a foreach loop for every array, without having to redeclare the foreach loop. Is there a way c# projects this? I was thinking of putting this in a Collection...? Please, critique my code. foreach (TextBox tb in vert) { if (tb.Text == box.Text) conflicts.Add(tb); } foreach (TextBox tb in hort) { if (tb.Text == box.Text) conflicts.Add(tb); } foreach (TextBox tb in cube) { if (tb.Text == box.Text) conflicts.Add(tb); }

• Problem requesting a HTTPS with TCL

  - by Javier

  Hi Everybody, I'm trying to do the following request using TCL (OpenACS) http::register https 443 tls::socket set url "https://encrypted.google.com" set token [http::geturl $url -timeout 30000] set status [http::status $token] set answer [http::data $token] http::cleanup $token http::unregister https The problem is that when I read the $status variable I get "eof" and the $answer variable becomes empty. I tried enabling tls V.1 http::register https 443 [list tls::socket -tls1 1] and it works only for the site https://www.galileo.edu, but not for https://encrypted.google.com. The site what I'm trying to connect is https://graph.facebook.com/me/feed?access_token=... but it doesn't work. I used curl to retrieve the contents of the pages in HTTPS and it works, I have installed OpenSSL, so I can't see the problem, there is another way to do HTTPS connections with TCL?. I can't see if this is a problem of coding (maybe I'm registered wrong the https protocol) or maybe It is a bad configuration of my server. Hope somebody helps!! Thanks!

• Generate links for routes with non-parameter url segments on ASP.NET MVC 2

  - by spapaseit

  I have a route defined with several hardcoded (non-parameter) segments: routes.MapRoute(null, "suggestion/list/by/{tag}", new { controller = "Suggestion", action = "List", tag = UrlParameter.Optional }); Suppose I'm in the Index view of SuggestionController, which has a Suggestion object for Model, how can I create a link that matches that route? I'd rather use one of the provided helpers and keep the route name as null in order to avoid hard-coding to much on my views, but I can't figure out how to user these non-parameter segments in Html.ActionLink or RouteLink methods. I've even tried to render the link using plain ol' html <a href="/suggestion/list/by/<%=Model.Tag %>"><%=Model.Tag %></a> but this somehow didn't match the route either. There's probably a very simple solution and I might be over-complicating things in mi mind, but I'm at a loss. Any ideas? Thanks in advance.

• Best way to plan a task ?

  - by Indigo Praveen

  Hi All, As I am very new to programming, I am very curious about learning the best ways/practices of programming. Whenever I want to write any program , I strat directly with coding while some guys say that you should plan your program first before starting the code. But I don't understand the real value of creating the class diagrams and all that kind of stuff coz I think that ultimately I have to write the code. Can you guys please share your experiences about how you are doing your programming means what is your first step when you start an application.

• Yield In VB.NET

  - by MagicKat

  C# has the keyword called yield. VB.NET lacks this keyword. I am curious how some of the VB programmers have gotten around the lack of this keyword. Do you implement your own iterator class? Or do you try and code to avoid the need of an iterator? The yield keyword does force the compiler to do some coding behind the scenes. http://blogs.msdn.com/oldnewthing/archive/2008/08/12/8849519.aspx is a good example of that.

• Why Use PHP OOP over Basic Functions and When?

  - by Codex73

  There are some posts about this matter, but I didn't clearly get when to use Object Oriented coding and when to use programmatic functions in an include. Somebody also mentioned to me that OOP is very heavy to run, and makes more workload. Is this right? Lets say I have a big file with 50 functions, why will I want to call these in a class? and not by function_name(). Should I switch and create object which holds all of my functions? What will be the advantage or specific difference? What benefits does it bring to code OOP in php ? Modularity?

• If you can't do a Support Role, does this mean you should not be in development?

  - by Alex

  Hi, I've been shifted around roles a lot, and have been put in a support role which seems to deal out a lot of rubbish due to poor business management. Anyway, my line manager says that he's not sure he would recommend me for a developer role as they regard support as a poor technical role. What I resent is the fact that not all the information is available to us about what we're supporting and I miss coding. This thing I'm supporting has been regarded as a disaster when it went in and is still highly unstable. The thing is...does he have a point about Support roles being under developers, or are they completely two different kettle of fish?

• Visual Studio web tests: Can a coded webtest be run through the Web Test Editor run view?

  - by Frank Rosario

  Hello, Full disclosure, I'm new to Visual Studio Web Tests and coding for them. I've written a webtest; coded in VB; it runs great. Our QA engineer wants to use this script for performance testing; but he wants the nice GUI that comes when you build a WebTest with the VS WebTest Editor and run it. Is there a way to run a coded webtest through this view? He wants to be able to view each test as it runs to see which pages are having issues, but within the GUI he's used to. Alternatively, I know I could just code something that writes out to a log file; but before I go with that solution; I just wanted to see if this is possible. Any constructive input is greatly appreciated.
