• How important is the .NET programming language when you choose a new job?

  - by Luhmann

  We are currently hiring at the company where I work, and here the codebase is in VB.Net. We are worried that we miss out on a lot of brilliant programmers, who would never ever consider working with VB.Net. My own background is Java and C#, and I was somewhat sceptical as to whether it would work out with VB, as - to be honest - i didn't care much for VB. After a month or so, I was completely fluent in VB, and a few months later i discovered to my surprise, that I actually like VB. I still code my free time projects in C# and Boo though. So my question is firstly, how important is language for you, when you choose a new programming job? Lets say if its a great company, salary is good, and generally an attractive work-place. Would you say no to the perfect job, if the language wasn't your preferred dialect? VB or C# is one thing, but how about Java or C# etc. Secondly if the best developers won't join your company because of your language or platform, would you consider changing, to get the right people? (This is not a language bashing thread, so please no religious language wars) NB: This is Community Wiki

• Creating a dynamic two-column iOS spinning wheel with HTML/Javascript

  - by JSW189

  I am trying to create a dynamic two-column spinning wheel for iOS Safari using this HTML/Javascript wheel. However, I am having trouble getting the value of the first column to change the results of the second column. I have tried using an if statement to get the value of the first variable (var beverage) and add the value of the second column correspondingly. Does anybody know what I am doing wrong/if there is a better approach? function openBirthDate() { var beverage = { 1:'Coffee', 2:'Soda' }; //THIS IS WHERE I'M HAVING TROUBLE var results = SpinningWheel.getSelectedValues(); if (results.values === 1) { var company = { 1:'Starbucks', 2:'Dunkin Donuts' }; } else { var company = { 1:'Coke', 2:'Pepsi' }; } var size = { 1:'Tall', 2:'Grande', 3:'Venti' }; SpinningWheel.addSlot(type, '', 1); SpinningWheel.addSlot(company, '', 1); SpinningWheel.addSlot(size, '', 1); SpinningWheel.setCancelAction(cancel); SpinningWheel.setDoneAction(done); SpinningWheel.open(); } function done() { var results = SpinningWheel.getSelectedValues(); document.getElementById('result').innerHTML = 'values: ' + results.values.join(' ') + '<br />keys: ' + results.keys.join(', '); } function cancel() { document.getElementById('result').innerHTML = 'cancelled!'; } window.addEventListener('load', function(){ setTimeout(function(){ window.scrollTo(0,0); }, 100); }, true);

• Querying calender events even if they do not have any for the day

  - by StealthRT

  Hey everyone, i am trying to figure out a way of query my mysql server so that even if a company does not have anything posted for the day the user clicks on their logo, it still adds them to the list. That sounds a little confusing so let me try to explain it another way. Say i have 3 company's in my database: Comp1 Comp2 Comp3 And Comp1 & Comp3 have something for today on the calender but Comp2 does not. I still need it to populate and place that company on the page but have something along the lines of "nothing on the calender for today". The other 2 companys (Comp1 & Comp3) would show the calender posting for that day. This is the code i have right now: SELECT clientinfo.id, clientinfo.theCompName, clientinfo.theURL, clientinfo.picURL, clientinfo.idNumber, clientoffers.idNumber, clientoffers.theDateStart, clientoffers.theDateEnd FROM clientinfo, clientoffers WHERE clientinfo.accountStats = 'OPEN' AND clientinfo.idNumber = clientinfo.idNumber AND '2010-05-08' BETWEEN clientoffers.theDateStart AND clientoffers.theDateEnd GROUP BY clientinfo.idNumber ORDER BY clientinfo.theCompName ASC That executes just fine but for Comp2, it just places the calender info from Comp1 into it when it really doesn't have anything. The output looks like this: Comp1 | 2010-05-08 | this is the calender event 1 | etc etc Comp2 | 2010-05-08 | this is the calender event 1 | etc etc comp3 | 2010-05-09 | this is the calender event 2 | etc etc Any help would be great :o) David

• Multiple "ObjectChangeTracker" getting created, can it be avoided?

  - by user555937

  Hi, We are working on a POC where we have following architecture (MVVM), WPF(Client) + WCF + Model(DataAccess)+ ADO.Net Entity Framework 4.0 (with SQL Server 2008 R2 as DB) All are different projects. In the DataAccess layer we have created different Entity Models(edmx) based on the functionality. The tables under perticular flow are grouped and created different entity models. We are using self tracking entities to and fro to communicate with the WPF client through wcf service. For Single model everything works fine. But when we created a Multiple models then few issues started coming. Mutliple models have few duplicate tables/entities. Two probels are, 1) When we try to access entities from different models mutiple objects "ObjectChangeTracker" are getting created. E.g. CompanyModel(edmx) - Company(Entity) - ObjectChangeTracker, ObjectState ProductModel(edmx) - Customer(Entity) - ObjectChangeTracker1, ObjectState1 OrderModel(edmx) - Oder(Entity) - ObjectChangeTracker2, ObjectState2 Is there any way to avoid this? 2) There are few tables which shared across the Models, E.g. Company(Entity) is used in All above mdoels. During compile time it does not thow any error. But run time It gives error saying "Schema specified is not valid. Errors: The mapping of CLR type to EDM type is ambiguous because multiple CLR types match the EDM type "Company"".. To resolve this, we renamed the entities with some prefix to make them Unique. Is there any other way we can resolve this without changing the name of the entity in the same assembly? Thanks in advance and appreciate if anyone has approach for these issues. Thanks, Kiran

• Why is short project lifetime and other situation-specific reasons used to excuse crappy code? [clos

  - by sharptooth

  Every now and then (including on SO) people say things implying that "if the project is short lived you can leave obvious defects there" or "that memory leak only accounts for 100 bytes per whole program lifetime and could be left". Now in my practice I always reuse company-owned code to the greatest extent I can. Like if I need something and I can find it in the company codebase I take it from there and reuse or adapt. This means that any crappy code will be reused as well and I might notice or not notice defects therein. So the defect in some "test we only need for a month" can slip into a proram we ship to customers. And a leak that "only accounted for 100 bytes per lifetime" now could account for 100 bytes 10 times per second in a server application intended to run for months. That's why I don't understand why excuses like that are offered. Is our compamy the only one having a source control? Or are we the only company that requires writing human-readable code? Could anyone shed a light on why people seriously offer such excuses?

• Freelance web hosting - what are good LAMP choices?

  - by tkotitan

  I think it's best if I ask this question with an example scenario. Let's say your mom-and-pop local hardware store has never had a website, and they want you, the freelance developer to build them a website. You have all the skills to run a LAMP setup and admin a system, so the difficult question you ask yourself is - where will I host it? As you aren't going to host it out of the machine in your apartment. Let's say you want to be able to customize your own system, install the version of PHP you want, and manage your own database. Perhaps the best kind of hosting is to get a virtual machine so you can customize the system as you see fit. But this essentially a "set it and forget it" site you make, bill by the hour for, and then are done. In other words, the hosting should not be an issue. Given the requirements of hosting a website: Unlimited growth potential needing good amounts of bandwidth to handle visitors Wide range of system and programming options allowing it to be portable Relatively cheap (not necessarily the cheapest) or reasonable scaling cost Reliable hosting with good support Hosted entirely on the host company's hardware Who would you pick to host this website? Yes I am asking for a business/company recommendation. Is there a clear answer for this scenario, or a good source that can reliably give the current answer? I know there are all kinds of schemes out there. I'm just wondering if any one company fills the bill for freelancers and stands out in such a crowded market.

• Strange problem on some client's browsers

  - by Gustavo Cardoso

  We are fighting a strange problem on the company that I work. We created a site of a promotion to a client where its consumers can register products barcodes to win prizes. The site was created using PHP and MySQL. The site uses SSL on every form. However, some consumers report to the client's call-center they was no able make a registration at the site. We try everything, but we cannot, by no ways, reproduce the problem. The consumers reported the problem on several browsers ranging from IE8 to Firefox, the problem is same on everyone them. One co-woker this weekend was able to catch this same bug on his wife's notebook and brought her computer to the company so we could test. However, here on the company the problem didn't happened and we can make the registration normally. We suppose this problem could be a matter of encoding and special characteres like ã and ç. But we are sure that all source files are UTF8- with BOM. We also suspect of MSXml version, but we are note sure anymore. Because of legal impediments the client cannot ask the consumers to install anything on they computers to test or fix the problem. Sorry but by complience rules we also cannot share the url of the site, what is a pity. I know it is too much on vacuun, but perhaps you could had crossed something similar. Thank you

• Using Uploadify, I'm renaming uploaded files via uploadify.php, how do I get the check script to now check for this renamed file??

  - by Rob Macintosh

  I've modified my uploadify.php file to rename my uploaded files, i'm appending them with my clients company name. As you can see i'm using scriptData to set the company name, so that uploadify.php can use it. documents.php 'scriptData': { 'PHPSESSID': '<?php echo session_id();?>', 'client_company': '<?php echo $_SESSION['company'] . "-";?>' }, This all works great - but now it breaks my check.php. I'm using the default check script, but now it simply thinks the file doesn't exist, so it overwrites it. I've tried appending the client_company POST variable to the file check; check.php $fileArray = array(); foreach ($_POST as $key => $value) { if ($key != 'folder') { if (file_exists($_SERVER['DOCUMENT_ROOT'] . $_POST['folder'] . '/' . $_POST['client_company'] . $value)) { $fileArray[$key] = $value; } } } echo json_encode($fileArray); But it doesn't work :( Can anyone help?

• How do I organize C# classes that inherit from one another, but also have properties that inherit from one another?

  - by Chris

  I have an application that has a concept of a Venue, a place where events happen. A Venue is owned by a Company and has many VenueParts. So, it looks like this: public abstract class Venue { public int Id { get; set; } public string Name { get; set; } public virtual Company Company { get; set; } public virtual ICollection<VenuePart> VenueParts { get; set; } } A Venue can be a GolfCourseVenue, which is a Venue that has a Slope and a specific kind of VenuePart called a HoleVenuePart: public class GolfCourseVenue { public string Slope { get; set; } public virtual ICollection<HoleVenuePart> Holes { get; set; } } In the future, there may also be other kinds of Venues that all inherit from Venue. They might add their own fields, and will always have VenueParts of their own specific type. My declarations above seem wrong, because now I have a GolfCourseVenue with two collections, when really it should just have the one. I can't override it, because the type is different, right? When I run reports, I would like to refer to the classes generically, where I just spit out Venues and VenueParts. But, when I render forms and such, I would like to be specific. I have a lot of relationships like this and am wondering what I am doing wrong. For example, I have an Order that has OrderItems, but also specific kinds of Orders that have specific kinds of OrderItems.

• Avoid slowdowns while using off-site database

  - by Anders Holmström

  The basic layout of my problem is this: Website (ASP.NET/C#) hosted at a dedicated hosting company (location 1) Company database (SQL Server) with records of relevant data (location 2). Location 1 & 2 connected through VPN. Customer visiting the website and wanting to pull data from the company database. No possibility of changing the server locations or layout (i.e. moving the website to an in-office server isn't possible). What I want to do is figure out the best way to handle the data acces in this case, minimizing the need for time-expensive database calls over the VPN. The first idea I'm getting is this: When a user enters the section of the website needing the DB data, you pull all the needed tables from the database into a in-memory dataset. All subsequent views/updates to the data is done on this dataset. When the user leaves (logout, session timeout, browser closed etc) the dataset gets sent to the SQL server. I'm not sure if this is a realistic solution, and it obviously has some problems. If two web visitors are performing updates on the same data, the one finishing up last will have their changes overwriting the first ones. There's also no way of knowing you have the latest data (i.e. if a customer pulls som info on their projects and we update this info while they are viewing them, they won't see these changes PLUS the above overwriting issue will arise). The other solution would be to somehow aggregate database calls and make sure they only happen when you need them, e.g. during data updates but not during data views. But then again the longer a pause between these refreshing DB calls, the bigger a chance that the data view is out of date as per the problem described above. Any input on the above or some fresh ideas would be most welcome.

• What tools do you have at your disposal as a manager to promote a way of thinking

  - by John Leidegren

  This question goes beoynd just programming, but I'd like to get some input on this, if that's okay with the community. Preferably from people that do a lot of coding themselves but also manage other people coding. My problem is this. We have all these ideas that we know is good for the overall strategy of the company and the problem is not figuring out what to do, it's to come about this change. Just telling someone to do things differently isn't enough and it's hard to promote a mind set that is shared within all of the company, (this will take time). If I could jump forward I'd like it if we could create a very nurturing company culture that promotes these ideals cross all areas but I'm not sure what tools to use. And by tools I mean anything I'm legally permitted to do. e.g. we could talk about, we could arrange traning sessions, we could spend more time in meeting (talk about it more), we could spend more time designing, we could spend more time pair-programming, we could add/remove incentive or we could encurage more play. Ultimately if we did all of these things what will be the recurring theme that ties this together. I'd like to be able to answer the question -- why should we do things like this? -- and come up with an answer that explains how important it is to think about our ideals from begining to end. I've puposly avoided to talk about or specifics of the situtation becuase I believe that it narrows things down too much. But I guess, by know you either know how to answer this question or you're as confused as I am ;) I'd love to hear from people who had to bring about a change in order to go from chaos to order, or fix something in the organization which wasn't working. And I'd like to hear it from the perspective of the developer and designer. -- or -- You could simply weigh in on what are the most important qualities in an organization encurage or stimulate rigid fun development cycle from start to finish?

• StreamReader not working as expected

  - by Jon Preece

  Hi, I have written a simple utility that loops through all C# files in my project and updates the copyright text at the top. For example, a file may look like this; //Copyright My Company, © 2009-2010 The program should update the text to look like this; //Copyright My Company, © 2009-2010 However, the code I have written results in this; //Copyright My Company, � 2009-2011 Here is the code I am using; public bool ModifyFile(string filePath, List<string> targetText, string replacementText) { if (!File.Exists(filePath)) return false; if (targetText == null || targetText.Count == 0) return false; if (string.IsNullOrEmpty(replacementText)) return false; string modifiedFileContent = string.Empty; bool hasContentChanged = false; //Read in the file content using (StreamReader reader = File.OpenText(filePath)) { string file = reader.ReadToEnd(); //Replace any target text with the replacement text foreach (string text in targetText) modifiedFileContent = file.Replace(text, replacementText); if (!file.Equals(modifiedFileContent)) hasContentChanged = true; } //If we haven't modified the file, dont bother saving it if (!hasContentChanged) return false; //Write the modifications back to the file using (StreamWriter writer = new StreamWriter(filePath)) { writer.Write(modifiedFileContent); } return true; } Any help/suggestions are appreciated. Thanks!

• javascript array/object issue

  - by FlyingCat

  I am trying to push elements to an array. for (a=0; a < test.length; a++){ if(this.testnumber != test[a].number){ //it will only loop 8 times under conditional statement group = { title: test.Title , ID: test.ID, contents: [] }; this.company.push(group); this.testnumber = test.number[a]; } //outside of if conditional statement.. it will loop 15 times //i want every test[a].conetents get pushed to group.contents array. //this.company is the final variable I need for this function... group.contents.push(test[a].contents); } However, when I do console.log(this.company); I see 8 elmements with only 1 element in each group.contents array The ideal situation is to have 8 elements with 2 to 3 elements in the group.contents array I hope I explain my situation well. Any idea how to solve my issue? Thanks a lot!

• Windows Workflow Foundation 4.0 Designer Rehosting with Custom Activities

  - by Robert

  I have several WF 4.0 workflows that I have created for an application my company is developing. Some of these workflows are simple, and some are very complex (i.e. many steps, several different types of activities, custom activities). For many of these workflows, I have created several custom code activities to support some internal process types. The workflows work great and we have had very few problems when it comes to maintaining them within VS 2010. We now want to move that responsibility off to our business users, so I have created a WPF application to rehost the WF designer (according to the MS samples). My problem is that when I open one of the workflows that contains custom code activities, those activities are represented as red boxes with the error message of "Activity could not be loaded because of errors in XAML." I have done research and have found several posts that mention that this is usually a problem with namespacing and referencing. The rehosted designer is in a namespace similar to this: Company.Application.Workflow.Designer And the custom code activities are contained within a separate custom workflow library, which I have included as a reference in the designer project. The library's namespace is similar to this: Company.Application.Workflow.Data.Activities As I have mentioned, the library is set as a reference in the designer's project, and I see it being copied to the output when I build the project. I have also included the reference in the XAML of the main designed application. What am I missing?

• How do I create a polymorphic model with a collection_select?

  - by muxe

  This are my models: class Speaker < ActiveRecord::Base belongs_to :session, :foreign_key => :session_id, :class_name => :Session belongs_to :speakable, :polymorphic => true end class Session < ActiveRecord::Base has_many :speakers accepts_nested_attributes_for :speakers end class Person < ActiveRecord::Base has_many :speakers, :as => :speakable end class Company < ActiveRecord::Base has_many :speakers, :as => :speakable end What I want to do now is something like this: app/views/sessions/edit.html.erb <% f.fields_for :speakers do |sf| %> <p> <%= sf.label :speaker %><br /> <%= sf.collection_select :speakable, Company.all + Person.all, :id, :full_name %> </p> <% end %> But it is not working because of the polymorphic assignment. How do I approach this problem? EDIT: The Error is: undefined method `base_class' for String:Class with params being: "speaker"=>{"speakable"=>"1063885469", "session_id"=>"1007692731"} The value passed to speakable is the id of the Speaker/Company. Yes, this is the value I specified the collection_select to return, but how can I manage to supply both values (speakable_id and speakable_type) ?

• best PHP programming approach?

  - by Nazmin

  Hello guys, i guess that many of us has acceptable years of experience in PHP programming, me myself got 5 years programming in PHP since in University (not very solid), i just want to gather some suggestion here, what is better approach in PHP OOP? Since there is a lot of PHP framework out there as well as javascript framework, can anyone share their experience in using one of them as well as using both of the PHP and javascript framework together especially for developing enterprise system? (my company want to start using framework, ISP company) if someone has his/her own framework or class or php file so on and so forth, mind to share? now I've only database connection class. I've never use any php framework before, just jquery as javascript framework, my company has a messed up of programming approach because they did not actually a software house, so all the files are scattered across the server, I see that there are some question before about the framework but i just want to know you all approaches on OOP and in developing massive web apps using PHP, or maybe someone kind enough to share their solid written class. Also pro's and con's of all this things. Thanks in advance.

• Help converting subquery to query with joins

  - by Tim

  I'm stuck on a query with a join. The client's site is running mysql4, so a subquery isn't an option. My attempts to rewrite using a join aren't going too well. I need to select all of the contractors listed in the contractors table who are not in the contractors2label table with a given label ID & county ID. Yet, they might be listed in contractors2label with other label and county IDs. Table: contractors cID (primary, autonumber) company (varchar) ...etc... Table: contractors2label cID labelID countyID psID This query with a subquery works: SELECT company, contractors.cID FROM contractors WHERE contractors.complete = 1 AND contractors.archived = 0 AND contractors.cID NOT IN ( SELECT contractors2label.cID FROM contractors2label WHERE labelID <> 1 AND countyID <> 1 ) I thought this query with a join would be the equivalent, but it returns no results. A manual scan of the data shows I should get 34 rows, which is what the subquery above returns. SELECT company, contractors.cID FROM contractors LEFT OUTER JOIN contractors2label ON contractors.cID = contractors2label.cID WHERE contractors.complete = 1 AND contractors.archived = 0 AND contractors2label.labelID <> 1 AND contractors2label.countyID <> 1 AND contractors2label.cID IS NULL

• WPF binding comboboxes to parent- child model

  - by PaulB

  I've got a model with a few tiers in it - something along the lines of ... Company Employees Phone numbers So I've got a ListBox showing all the companys in the model. Each ListBoxItem then contains two comboboxes ... one for employees, one for phone numbers. I can successfully get the employee combo to bind correctly and show the right people, but I'd like the phone combo to show the numbers for the selected employee. I'm just setting the DataContext of the ListBox to the model above and using the following data template for each item <DataTemplate x:Key="CompanyBody"> <StackPanel Orientation="Horizontal"> <Label Content="{Binding Path=CompanyName}"></Label> <ComboBox Name="EmployeesCombo" ItemsSource="{Binding Path=Company.Employees}"></ComboBox> <!-- What goes here --> <ComboBox DataContext="???" ItemsSource="??" ></ComboBox> </StackPanel> </DataTemplate> I've tried (naively) <ComboBox ItemsSource="{Binding Path=Company.Employees.PhoneNumbers}" ></ComboBox> and <ComboBox DataContext="EmployeesCombo.SelectedValue" ItemsSource="{Binding Path=PhoneNumbers}" ></ComboBox> and all other manner of combinations ...

• Is it a wise decision to go from dev to third line/Tier 3 dev support?

  - by dotnetdev

  Hi, I am an experienced, mid-level developer. However, I recently spotted a job for a company which is small but has a lot of emphasis on training(beyond the basic technical training, but also mentoring, leadership training, etc). The role is 3rd line so still very technical. It's in app support so it's post implementation development rather than pure out-and-out development like I do now (or don't, as the senior devs do all of the interesting work). However, and this is the question - is this sort of career move common? Also, wouldn't a tech support role be a big shock to the system because I've never dealt with customers? I therefore think it's a bad move? Working in dev, I am used to the lack of customer contact and it is all filtered through by my manager. But in tech support, contacting customers/rude customers could be scary. I don't mind fixing other people's mistakes (better than me making mistakes!) and doing post-implementation dev for production systems (will give me a lot of discipline), and I do get bored sitting in the same place looking/talking to the same people in suits (I work in a corporate environment). The company puts A LOT of emphasis on training and prospects, which I don't get in the current (big) company I work at. Any advice on how to handle tech support is appreciated! Thanks

• Updating DIV with XML content on Hover (JQuery)

  - by Andrew Parisi

  Hi everyone! The concept of what I'm trying to do is fairly simple. I have a grid of company logos loaded through XSLT from an XML document, each with their own unique links to the company profiles. I have a separate div on the page, essentially a "preview" box. What I want to do is this: I roll over a logo, and it loads the name of the company and a short description into the preview div. This content is loaded through XML. I have been messing around with the Jquery load() function, changing the target document to load on Hover—and it almost gets what I want, but it loads the whole target XML document into the div. How can I separate this target XML data into separate divs? (which I have styled differently) I'd assume I would make use of Ajax in some way. I want to load the <name> node into the name_div, and the <desc> node into the description_div, and have them update on hover. Thanks in advance for the help!

• What choices do I have for a future in software development?

  - by user354892

  After graduating from college with a degree in mathematics and a minor in computer science, I took over a year to find my first programming job. I very much enjoy my work environment, but sometimes I feel like I'm not developing professionally as quickly as I am capable of. My company does mostly web programming. The project that I work on is basically a front-end for a SQL database. The entire project is (AFAIK) coded is VB.NET. I've been working on the back-end logic of the program. After some time on the job, we decided that designing web pages is not my cup of tea. It seems like the thing that I spend more time on than anything else is searching the web and SO for information about poorly documented .net and web APIs. This does not make me happy; is this normal for a programming job; I don't think it is. It really hit me the other day when i saw a question about math asked here and I didn't know the answer; I feel like my knowledge is going stale! I was previously almost hired by another company where they design graphic-intensive battle simulations for the military. I sometimes wonder what my life might be like if I had that job. I feel like my math and problem solving skills might have been a better fit at this other company. Within the wide field of software development, there are a number of directions in which to go as evidenced by the huge variety of topics discussed here on StackOverflow. I would like to feel like I'm going in the direction where I will make the most of my skills and have a satisfying career. Let me word this question as clearly as possible: given the wide breadth of the field of software development, how does it break down into sub-fields and what are the considerations for developing a software development career. I do not want to manage my career by default.

• XMLNodes being appended to an XMLNode are "undefined"? Actionscript 2.0 is being unkind

  - by DigitalMercenary

  If anyone can offer an explanation for this one, I'd LOVE to see it! I was required to append a legacy application to display 20 random questions from an XML data source, as opposed to the total of 70 questions that are part of the original XML. No big deal, right? WRONG! I got it to work just fine in the end, but it's a total HACK! For some reason, some of the nodes that I am appending to a dynamically generated XML document are being returned as "undefined". I kept getting between 16 and 20 questions to render until I modified my iteration from a 'for' loop to a 'do while' loop with the appropriate number of XMLNodes as the condition of the 'do while' loop. Can anyone offer an explanation? Below is the code, with some notes for the reader : function editXML(xml:XML):XML { var node:XMLNode = xml.firstChild; var newNode:XMLNode = new XMLNode(); var nodeArray:Array = new Array(); var usedNodes:Array = new Array(); var totalNodes:Number = node.lastChild.childNodes.length - 1; var nextNode:Number; var returnNode:XMLNode = new XMLNode(); var tempNode:XMLNode; var buildNode:XMLNode; var addNode:Boolean = true; var tempXML:XML = new XML(); var pagesNode:XMLNode = tempXML.createElement("pages"); tempXML.appendChild(pagesNode); tempXML.appendChild(node.childNodes[0]); tempXML.appendChild(node.childNodes[1]); tempXML.appendChild(node.childNodes[2]); var questionsNode:XMLNode = tempXML.createElement("pages"); tempXML.firstChild.appendChild(questionsNode); do { nextNode = Math.floor(Math.random()*totalNodes); **//random number to represent random node** //trace(nextNode + " nextNode"); **//check usedNodes Array to look for node.childNodes[nextNode]. If it already exists, skip and reloop.** trace(node.childNodes[1].childNodes[nextNode] + " : pre building Node " + totalNodes); if(usedNodes.length == 0) { buildNode = new XMLNode(); buildNode.nodeName = node.childNodes[1].childNodes[nextNode].nodeName; buildNode.nodeValue = node.childNodes[1].childNodes[nextNode].nodeValue; tempXML.firstChild.lastChild.appendChild(node.childNodes[1].childNodes[nextNode]) usedNodes.push(node.childNodes[1].childNodes[nextNode]); nodeArray.push(node.childNodes[1].childNodes[nextNode]); trace("adding first node : " + nodeArray.length); addNode = false; } else { for(var j:Number = 0; j < usedNodes.length; j++) { if(usedNodes[j] == node.childNodes[1].childNodes[nextNode]) { addNode = false; trace("skipping node : " + nodeArray.length); } } } **//if node not in usedNodes, add node to XML** if(addNode) { trace(node.childNodes[1].childNodes[nextNode] + " : building Node"); **//This trace statement produced a valid node** tempXML.firstChild.lastChild.appendChild(node.childNodes[1].childNodes[nextNode]); **//Before modifying the code from adding nodes to the xml from an Array called 'nodeArray' in a for loop to adding nodes directly to the xml in a do while loop with the length of the xml node used to retrieve data for the questions as the condition, I was not always getting 20 questions. Some of the nodes were being rendered as 'undefined' and not appended to the xml, even though they were traced and proven valid before the attemp to append them to the xml was made** usedNodes.push(node.childNodes[1].childNodes[nextNode]); } addNode = true; } while(tempXML.firstChild.lastChild.childNodes.length <= 19); trace(tempXML.firstChild.lastChild.childNodes.length + " final nodes Length"); courseXML = tempXML; //removes the old question list of 70 and replaces it with the new question list of 20. Question list is the last node. return tempXML; } If I had my choice, I would have rebuilt the whole application in Flex with AS3. I didn't have that choice. If anyone can explain this mystery, PLEASE DO! Thank you in advance!

• How to suppress an unwanted external Autodiscover lookup?

  - by chris

  In a small network with Exchange 2007, when starting Outlook 2010 (and once in a while afterwards), users get a prompt to confirm that it's safe to get account configuration information from cpanelemaildiscovery.cpanel.net/autodiscover/autodiscover.xml (I could read in a couple of forums that there is a bug in cpanel, but that's beside the point.) I'm puzzled because I can't find any autodiscover DNS entries anywhere, neither internally nor externally. The only hint is that we use an external hosting company for our website and for one single email address, which runs on cpanel. So I guess that Outlook makes an external DNS query to test all entries? It reates a lot of confusion for the users and frankly I'm not too happy that the external hosting company gets contacted by all our users. How can I suppress this behavior? Thanks

• Using AuthzSVNAccessFile for controlling SVN Access produces HTTP 400 Bad Request

  - by meeper

  I have a new repository on an existing subversion server that requires us to perform path based authorization within the repository. I found that the AuthzSVNAccessFile directive in apache is directly responsible for allowing this functionality. After fixing several other problems such as AuthzSVNAccessFile preventing SVNListParentPath from operating properly, I am left with one single problem. I can checkout, I can update, I can commit, BUT I cannot execute an SVN COPY for performing branch/tagging operations. The moment I comment out the AuthzSVNAccessFile line in the Apache config everything works as expected except the obvious path authorizations. Versions: The server OS is Debian 6.0.7 (Squeeze) Apache 2.2.16-6+squeeze11 Server Subversion 1.6.12dfsg-7 Clients are running windows Clients tried are: TortoiseSVN 1.8.2 Build 24708 64bit SVN CLI Client 1.8.3 (r1516576) Authentication is performed via AD to a Windows 2003 domain and appears to be operating normally. I have stripped out all other configurations and repository setups to produce this single configuration that reproduces the problem. Apache Configuration: <VirtualHost *:443> ServerName svn-test.company.com ServerAlias /svn-test ServerAdmin [email protected] SSLEngine On SSLCertificateFile /etc/apache2/apache.pem ErrorLog /var/log/apache2/svn-test_error.log LogLevel warn CustomLog /var/log/apache2/svn-test_access.log combined ServerSignature On # Repository Access to all Repositories <Location "/"> DAV svn SVNParentPath /var/svn SVNListParentPath on AuthBasicProvider ldap AuthType Basic AuthzLDAPAuthoritative Off AuthName "Subversion Test Repository System" AuthLDAPURL "ldap://adserver.company.com:389/DC=corp,DC=company,DC=com?sAMAccountName?sub?(objectClass=*)" NONE AuthLDAPBindDN "CN=service_account,OU=ServiceIDs,OU=corp,OU=Delegated,DC=na,DC=corp,DC=company,DC=com" AuthLDAPBindPassword service_account_password Require valid-user SSLRequireSSL </Location> # <LocationMatch /.+> is a really dirty trick to make listing of repositories work # http://d.hatena.ne.jp/shimonoakio/20080130/1201686016 <LocationMatch /.+> AuthzSVNAccessFile /etc/apache2/svn_path_auth </LocationMatch> </VirtualHost> SVN Access File: [/] * = rw The repository used (AuthTestBasic) consists of the following directory structure and contains no externals (this is a literal listing, not an example): / /branches/ /tags/ /trunk/ /trunk/somefile.txt Tortoise produces the following error during a tag operation in it's tag result window: Adding directory failed: COPY on /authtestbasic/!svn/bc/2/trunk (400 Bad Request) The svn.exe CLI client produces the following error: C:\Users\e20epkt>svn copy https://servername/authtestbasic/trunk https://servername/authtestbasic/tags/tag1 -m "svn cli client" svn: E175002: Adding directory failed: COPY on /authtestbasic/!svn/bc/2/trunk (400 Bad Request) The Apache error log has nothing in it, however the apache access log has the following in it (IP addresses and usernames changed obviously): 10.1.2.100 -

Please note that, while yes this is a test repository on a test server, I am experiencing this same issue in this test setup where I have eliminated all other possible causes (mixed repository configurations, externals, etc). I have also confirmed that all files for the repository (/var/svn/authtestbasic) are owned by the Apache user www-data.

• SysAdmin Career Question: Internal or Client Based

  - by Malnizzle

  ServerFault Community, It seems there are two positions SysAdmins find themselves in, either you are working for a non-IT services based single client (your employer) and providing in-house IT support or you work for a company who provides out sourced IT services to multiple clients. Right now I work for a company who does the latter, and I often consider how nice it would be doing the in-house side of things, to just have one network I am focused on and instead of feeling like I have a dozen bosses between clients and internal management, I would just have one set of management and people to appease. There is also the technical aspect of every client wanting something different, and having to manage numerous different technology platforms, or trying to force clients into using the technologies we prefer, neither situation is enjoyable. Is this just "the grass is greener on the other side" syndrome, or is there some legitimacy to the the stress of client based IT work compared to being an in-house IT guy? Thanks!
