• how to get latex to hyphenate a word that contains a dash ?

  - by Gyom

  In a latex document I'm writing, I get an overfull hbox warning because of the word "multi-disciplinary", which happens to be rendered at the end of a line. I can get rid of this particular warning by changing it into multi-discipli\-nary, but the same problem will happen elsewhere, since this word is used a lot in the paper. I'd like to use the \hyphenation{} command instead, but obviously my tentative \hyphenation{multi-disci-pli-na-ry} does not work, because it does not understand the first dash correctly. What incantation do I need to get correct indentation in a word that already contains a dash ? Bonus question: where could I have found the answer to that question myself ?

• How do you change the image of a bullet point in LaTeX Beamer

  - by cheshirekow

  When I use the itemize environment, i.e. \begin{itemize} \item one \item two \item three \end{itemize} The bullet points are ugly bitmap graphics that have harsh (aliased) edges. I'd like it to be a nice, clean font character or vector graphic

• WPF ToolBar Separator shrinks to nothing when inside a StackPanel

  - by qntmfred

  Given the very simple wpf app <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="800"> <Grid> <ToolBar Height="50" > <MenuItem Header="Test1" /> <MenuItem Header="Test2" /> <StackPanel Orientation="Horizontal"> <Separator /> <MenuItem Header="Test3" /> <MenuItem Header="Test4" /> <MenuItem Header="Test5" /> </StackPanel> </ToolBar> </Grid> </Window> The Separator element shrinks to nothing. If I put the Separator just before the StackPanel begins, it will show up. Why does this happen? Is there a style setting that can be applied somewhere to avoid this?

• TeamCity for continuous integration with Visual Studio 2010 solutions/projects

  - by JeffryEngberg

  I am running TeamCity build 5.1.1 on a virtual machine that also hosts our SVN environment. A team I support has recently made the move from Visual Studio 2008/Silverlight 3.0 to Visual Studio 2010/Silverlight 4.0 and when investigating how to do continuous integration with Visual Studio 2010 solutions/projects, it is not as cut and dried as it appeared to be in Visual Studio 2008. Previously I was using Web Deployment Projects and targeting different Release Configurations in TeamCity, which would use the Web Deployment Project to package/deploy the code to our various environments. However when checking out the new Publish ability in Visual Studio 2010 I cannot find a way to specify which location to deploy to. Does everything need to be done in MSBuild now (in the solution file or maybe the Web project file?). If anyone has any examples of how they've done Continuous Integration using TeamCity and Visual Studio 2010, it would be greatly appreciated as I am coming up blank at the moment.

• What Test Environment Setup do Top Project Committers Use in the Ruby Community?

  - by viatropos

  Today I am going to get as far as I can setting up my testing environment and workflow. I'm looking for practical advice on how to setup the test environment from you guys who are very passionate and versed in Ruby Testing. By the end of the day (6am PST?) I would like to be able to: Type one 1-command to run test suites for ANY project I find on Github. Run autotest for ANY Github project so I can fork and make TESTABLE contributions. Build gems from the ground up with Autotest and Shoulda. For one reason or another, I hardly ever run tests for projects I clone from Github. The major reason is because unless they're using RSpec and have a Rake task to run the tests, I don't see the common pattern behind it all. I have built 3 or 4 gems writing tests with RSpec, and while I find the DSL fun, it's less than ideal because it just adds another layer/language of methods I have to learn and remember. So I'm going with Shoulda. But this isn't a question about which testing framework to choose. So the questions are: What is your, the SO reader and Github project committer, test environment setup using autotest so that whenever you git clone a gem, you can run the tests and autotest-develop them if desired? What are the guys who are writing the Paperclip Tests and Authlogic Tests doing? What is their setup? Thanks for the insight. Looking for answers that will make me a more effective tester.

• DataGridView: Scroll bar does not refreshed

  - by David.Chu.ca

  I am working (fixing bugs) on a project which was written in VS 2005. There is one DataGridView control on a form. When it is first time loaded, the control's data grid is populated with rows of data from a collection manually or in codes. Actually, there is method PopulateDataGrid() do the job. There is also another control on the form. When control is changed, the data grid will be cleared first and then rows are repopulated again through PopulateDataGrid(). The problem is that when the grid is refreshed, the vertical scroll bar does not get reset correctly. I thought it should be. Since the scroll bar is not reset, when I tried to click on grid and move down, I got exception: the max value of scroll bar was exceeded. All the settings for grid control are default values. For example, the ScrollBars is Both. The following is the only related place to set row auto size property: poDataGridView.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.DisplayedCellsExceptHeaders; I am not sure if there is any property I have to set in designer?

• Why am I getting this error when overriding an inherited method?

  - by Sergio Tapia

  Here's my parent class: public abstract class BaseFile { public string Name { get; set; } public string FileType { get; set; } public long Size { get; set; } public DateTime CreationDate { get; set; } public DateTime ModificationDate { get; set; } public abstract void GetFileInformation(); public abstract void GetThumbnail(); } And here's the class that's inheriting it: public class Picture:BaseFile { public override void GetFileInformation(string filePath) { FileInfo fileInformation = new FileInfo(filePath); if (fileInformation.Exists) { Name = fileInformation.Name; FileType = fileInformation.Extension; Size = fileInformation.Length; CreationDate = fileInformation.CreationTime; ModificationDate = fileInformation.LastWriteTime; } } public override void GetThumbnail() { } } I thought when a method was overridden, I could do what I wanted with it. Any help please? :)

• Codeigniter: how should I restructure db schema?

  - by Kevin Brown

  I don't even know if that's the right term. May it be known that I'm a major novice! I have three tables: users, profiles, and survey. Each one has user_id as it's first field, (auto-increment for users), and they're all tied by a foreign key constraint, CASCADE on DELETE. Currently, for each user, let's say user_id 1, they have a corresponding db entry in the other tables. For profiles it lists all their information, and the survey table holds all their survey information. Now I must change things...darn scope creep. Users need the ability to have multiple survey results. I imagine that this would be similar to a comment table for a blog... My entire app runs around the idea that a single user is linked to a constraining profile and survey. How should I structure my db? How should I design my app's db so that a user can have multiple tests/profiles for the test? Please assist! Any advice, information and personal-knowledge is appreciated! Right now the only way I know how to accompany my client is to create a pseudo-user for each test (so unnecessary) and list them in a view table (called "your tests")-- these are obtained from the db by saying: where user_id=manager_id

• how to merge ecommerce transaction data between two databases

  - by yamspog

  We currently run an ecommerce solution for a leisure and travel company. Everytime we have a release, we must bring the ecommerce site down as we update database schema and the data access code. We are using a custom built ORM where each data entity is responsible for their own CRUD operations. This is accomplished by dynamically generating the SQL based on attributes in the data entity. For example, the data entity for an address would be... [tableName="address"] public class address : dataEntity { [column="address1"] public string address1; [column="city"] public string city; } So, if we add a new column to the database, we must update the schema of the database and also update the data entity. As you can expect, the business people are not too happy about this outage as it puts a crimp in their cash-flow. The operations people are not happy as they have to deal with a high-pressure time when database and applications are upgraded. The programmers are upset as they are constantly getting in trouble for the legacy system that they inherited. Do any of you smart people out there have some suggestions?

• Parsing dbpedia JSON in Python

  - by givp

  Hello, I'm trying to get my head around the dbpedia JSON schema and can't figure out an efficient way of extracting a specific node: This is what dbpedia gives me: http://dbpedia.org/data/Ceramic_art.json I've got the whole thing as a JSON object in Python but don't really understand how to get the english abstract from this data. I've gotten this far: u = "http://dbpedia.org/data/Ceramic_art.json" data = urlfetch.fetch(url=u) json_data = json.loads(data.content) for j in json_data["http://dbpedia.org/resource/Ceramic_art"]: if(j == "http://dbpedia.org/ontology/abstract"): print "it's here" Not sure how to proceed from here. As you can see there are multiple languages. I need to get the english abstract. Thanks for your help, g

• How to get the value of a ComboBox within a DataGrid

  - by Jason Towne

  While this may be a simple problem, I'm having a heck of a time coming up with a solution. I have a DataGrid with a ComboBox as an ItemRenderer for one of my columns. When the user selects a row, I want to get the ComboBox's selected value for the selected row. Any suggestions? Some sample code: <mx:DataGrid id="myGrid" dataProvider="{myData}"> <mx:columns> <mx:DataGridColumn headerText="Column 1" dataField="dataField1" /> <mx:DataGridColumn headerText="Column 2" dataField="dataField2_Array"> <mx:itemRenderer> <mx:Component> <mx:HBox paddingLeft="5"> <mx:ComboBox id="myComboBox" dataProvider="{data.dataField2_Array}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:DataGridColumn> </mx:columns> </mx:DataGrid>

• How can I run an external program from C and parse its output?

  - by Josh Matthews

  I've got a utility that outputs a list of files required by a game. How can I run that utility within a C program and grab its output so I can act on it within the same program? UPDATE: Good call on the lack of information. The utility spits out a series of strings, and this is supposed to be complete portable across Mac/Windows/Linux. Please note, I'm looking for a programmatic way to execute the utility and retain its output (which goes to stdout).

• TFS Auto Shelve - New Visual Studio 2010 / TFS 2010 Extension

  - by MikeParks

  We've been working with the Visual Studio 2010 SDK and the TFS 2010 SDK a lot recently to create new Visual Studio Extensions. You can find these extensions in the Visual Studio Gallery. If you're a developer/programmer, you should check it out, they have some pretty cool tools out there. I'd be surprised if you told me you went there and couldn't find any tools that could help you. One of the new extensions Cory and I made is called TFS Auto Shelve. Check out the description and read about it below. If you're interested and you have VS 2010 w/TFS 2010, feel free to try it out and let us know what you think.

• Xdebug 2.0.5 with Zend Server CE PHP5.2.12 possible?

  - by notbrain

  I'm using Zend Server CE with PHP 5.2.12 on OSX Snow Leopard and want to use Xdebug. I've turned off Zend Data Cache, Zend Optimizer+, and Zend Debugger in the console. When I run $ cd ~/Downloads/xdebug-2.0.5 $ /usr/local/zend/bin/phpize I get Configuring for: PHP Api Version: 20041225 Zend Module Api No: 20060613 Zend Extension Api No: 220060519 The PHP API Version, 20041225, seems to be off from the documentation (aka wrong). When I continue installation with $ ./configure ---with-php-config=/usr/local/zend/bin/php-config $ make $ sudo make install The installed xdebug.so seems to be the wrong one. Which version of xdebug do I need for this PHP API version? The Zend API numbers are ok. I'm just confused at why the PHP API Version doesn't match. PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/zend/lib/php_extensions/xdebug.so' - (null) in Unknown on line 0 PHP 5.2.12 (cli) (built: Feb 17 2010 13:39:36)

• The very bare minimum of latex to compile documents

  - by ldigas

  I'm creating a relatively small console program which will be used by some other people as well. As part of its output it will be creating a tex file which will contain some two tables, a few rows of text and one plot. Not, my program is pretty small - under a Mb. The problem is I can't count on my users to have latex installed, so I'd like to include the very bare minimum required files to create it (pdf). What would be a good place to start searching on that topic, or even better, does anyone know what I would need to include with it to accomplish that ? I remember my last latex install being pretty ... well, gigantic. Kind regards !

• How to Optimize Your Website Using the Title Meta Tag

  When I browse the internet I am shocked to see just how many big websites which don't correctly utilize the TITLE META tag to extract as much weight as possible to their keyword they are optimizing for. From my experience the TITLE tag is one of the most powerful onsite SEO factors. We all are aware that back links with anchor text using the targeted page keyword is the most important factor but it never fails to amaze me just how much people ignore this powerful META tag.

• SEO - A Crash Course

  Search engine optimization, otherwise commonly referred to SEO, is a way to make web content appear as high as possible in search engine rankings. Here, we'll discuss a number of ways you can use this valuable tool to your advantage for your website. Using text on your website and on titles and things of this nature will be used to create placement on web pages. Keywords repeated throughout a page will bring it up towards the top based on the phrase a search engine user types into the search box. You will want to use a keyword phrase in your title tag, the website URL, and about a 4-6% keyword phrase density in your overall page text. Additional locations that these keyword phrases are important include within inbound links, within headings, in the beginning of a document, in alternative text tags, and in metatags.
