• Easy Flood Fill

  - by Jimmy

  Some advice, please. I'm just starting out in C#. I've managed to get some shapes created on a Windows form, and now I'd like to fill them with color. In the old C++ I studied years ago, there was a floodfill function that was really easy. It has been an unpleasant realization to find there's not a similar method available in regular old C#. Does anyone have advice for me, or some code, so I can implement filling without understanding GDI+, DirectX, or rest of the avalanche of acronyms that I've run into by researching this on the web? I need to fill irregular shapes, bounded by a certain color. Gradient and transparency control would be nice, but I'd settle for plain old solid fill right now, just to get a modicom of control over this. Any help, code or advice would be really appreciated.

• Adding a font for use in ReportLab

  - by Jimmy McCarthy

  I'm trying to add a font to the python ReportLab so that I can use it for a function. The function is using canvas.Canvas to draw a bunch of text in a PDF, nothing complicated, but I need to add a fixed width font for layout issues. When I tried to register a font using what little info I could find, that seemed to work. But when I tried to call .addFont('fontname') from my Canvas object I keep getting "PDFDocument instance has no attribute 'addFont'" Is the function just not implemented? How do I get access to fonts other than the 10 or so default ones that are listed in .getAvailableFonts? Thanks. Some example code of what I'm trying to make happen: from reportlab.pdfgen import canvas c = canvas.Canvas('label.pdf') c.addFont('TestFont') #This throws the error listed above, regardless of what argument I use (whether it refers to a font or not). c.drawString(1,1,'test data here') c.showPage() c.save() To register the font, I tried from reportlab.lib.fonts import addMapping from reportlab.pdfbase import pdfmetrics pdfmetrics.registerFont(TTFont('TestFont', 'ghettomarquee.ttf')) addMapping('TestFont', 0, 0, 'TestFont') where 'ghettomarquee.ttf' was just a random font I had lying around.

• Which information (files) of an eclipse-workspace should be tracked by source control

  - by Phuong Nguyen de ManCity fan

  I want to track the workspace of eclipse by source control so that important settings can be backed up. However, there are a lot of kind of *.index inside the .metadata folder of workspace. Some information are important, for example Mylyn repository, but some information is merely cached files and thus, doesn't make sense to me for being tracked. In short, what files inside eclipse workspace that should be tracked so that I can restore the working workspace after problems (like meta data file deleted, etc.)

• JPA - Performance with using multiple entity manager

  - by Nguyen Tuan Linh

  My situation is: The code is not mine I have two kinds of database: one is Dad, one is Son. In Dad, I have a table to store JNDI name. I will look up Dad using JNDI, create entity manager, and retrieve this table. From these retrieved JNDI names, I will create multiple entity managers using multiple Son databases. The problem is: Son have thousands of entities. It takes each Son database around 10 minutes to load all entities. If there is 4 Son databases, it will be 40 minutes. My question: Is there any way to load all entities and use them for all entity manager? Please look at the code below For each Son JNDI: Map<String, String> puSonProperties = new HashMap<String, String>(); puSonProperties.put("javax.persistence.jtaDataSource", sonJndi); EntityManagerFactory emf = Persistence.createEntityManagerFactory("PUSon", puSonProperties); PUSon - All of them use the same persistence unit log.info("Verify entity manager for son: {0} - {1}", sonCode, emSon.find(Son_configuration.class, 0) != null ? "ok" : "failed!"); This is the actual code where the loading of all entities begins. 10 mins.

• Unbelievable: Cannot cast from class X to its super class

  - by Phuong Nguyen de ManCity fan

  I'm encountering a very weird problem with Spring (3.0.1.RELEASE), TestNG (5.11) and Maven Surefire (2.5). I have a test class that extends a Spring helper class for testNG so that test context can be loaded from an xml file (that contains some bean definitions). My project was imported into eclipse using m2eclipse (using Import Maven Project) The class run fine in Eclipse TestNG runner. However, it throws this exception with Maven Surefire Caused by: java.lang.ClassCastException: com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:123) at org.springframework.beans.factory.xml.DefaultDocumentLoader.createDocumentBuilderFactory(DefaultDocumentLoader.java:89) at org.springframework.beans.factory.xml.DefaultDocumentLoader.loadDocument(DefaultDocumentLoader.java:70) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:388) I have eliminated all involved dependencies in my pom so that the two classes com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl and javax.xml.parsers.DocumentBuilderFactory are coming from JRE only (the rt.jar). So, it looks so unbelievable to me. I wonder if there is any mechanism in loading class that can explain for this behavior? Thanks.

• UTF-8 BOM in php response to mootools xmlhttprequest

  - by Jimmy

  Hi, I'm writing my first little AJAX-enabled Joomla component. I'm using mootools. I got a xmlhttprequest to contact my Joomla component, and the component returns a response - just plain text echoed by php, like echo 'Hello World!'; It's all working fine, except wireshark tells me that the response is prepended with \357\273\277\357\273\277 when it gets read by the javascript on the client side. This shows up as a little square before the response in an alert box that the script shows. I don't explicitly set the encoding on the xmlhttprequest; mootools docs say that it defaults to UTF8. What's the right way to handle this? Should I be setting the encoding on the request? Mime type? Should the javascript get rid of it? I'm not planning to have any characters requiring UTF8 in the response, so using plain old ascii would be ok for me too. Thanks

• Excluding files from being deployed with Capistrano while still under version control with Git

  - by Jimmy Cuadra

  I want to start testing the JavaScript in my Rails apps with qUnit and I'm wondering how to keep the test JavaScript and test runner HTML page under version control (I'm using Git, of course) but keep them off the production server when I deploy the app with Capistrano. My first thought is to let Capistrano send all the code over as usual including the test files, and write a task to delete them at the end of the deployment process. This seems like sort of a hack, though. Is there a cleaner way to tell Capistrano to ignore certain parts of the repository when deploying?

• How to debug GWT using Ant

  - by Phuong Nguyen de ManCity fan

  I know that the job would be simpler if I use Google Plugin for Eclipse. However, in my situation, I heavily adapted Maven and thus, the plugin cannot suit me. (In fact, it gave me the whole week of headache). Rather, I relied on a ant script that I learned from http://code.google.com/webtoolkit/doc/latest/tutorial/appengine.html The document was very clear; I follow the article and successfully invoked DevMode using ant devmode. However, the document didn't tell me about debugging GWT (like Google Plugin for Eclipse can do). Basically, I want to add some parameter to an ant task that expose a debug port (something like (com.google.gwt.dev.DevMode at localhost:58807)) so that I can connect my eclipse to. How can I do that?

• Validating textboxes and checkboxes then add the values of those checkboxes

  - by TiTi Nguyen

  I am very new to Javascript. I am running to a problem and don't know how to solve it. Could you please help? Basically, I want to create some textboxes and checkboxes in a form. Then I have to validate those fields, and add the values of the checkboxes if they are selected. One of the textboxes asking for how many semesters attended, and 3 checkboxes with value of 100, 1000, and 750. Whichever checkbox is selected, it should multiply its value to the number of semesters attended. For example if the first two checkboxes are selected then totalCost = (100+1000)* semester. Here is my code: User Name: <label>User Address: <input type = "text" id ="address" size = "30"/></label> <br/><br/> <label> User E-mail address: <input type = "text" id ="email" size = "30"/></label> <br/><br/> <label> User Phone number: <input type = "text" id ="phone" size = "30"/></label> <br/><br/> <label> User area code: <input type = "text" id ="area" size = "30"/></label> <br/><br/> <label> User SSN: <input type = "text" id ="ssn" size = "30"/></label> <br/><br/> <label> User Birthday: <input type = "text" id ="birthday" size = "30"/></label> <br/><br/> <label> Number of semester attended: <input type = "text" id ="semester" size = "3"/></label> <br/><br/> <label><input type="checkbox" id="box_book" value="100"/>Books $100 per semester</label> <br/> <label><input type="checkbox" id="box_tuition" value="1000"/>Tuition $1000 per semester</label> <br/> <label><input type="checkbox" id="box_room" value="750"/>Room and Board $750 per semester</label> <br/> <input type="reset" id="reset"/> <input type="submit" id="submit" onclick="checking()"/> <p/> </form> function checking() { var name=document.forms["myForm"]["name"].value; var address=document.forms["myForm"]["address"].value; var email=document.forms["myForm"]["email"].value; var atpos=email.indexOf("@"); var dotpos=email.lastIndexOf("."); var phone=document.forms["myForm"]["phone"].value; var area=document.forms["myForm"]["area"].value; var ssn=document.forms["myForm"]["ssn"].value; var birth=document.forms["myForm"]["birthday"].value; var semester=document.forms["myForm"]["semester"].value; var boxBook = document.forms["myForm"]["box_book"].value; var boxTuition = document.forms["myForm"]["box_tuition"].value; var boxRoom = document.forms["myForm"]["box_room"].value; if (name==null || name=="") { alert("Please fill in your name."); return false; } if (address==null || address=="") { alert("Please fill in your address."); return false; } if (atpos<1 || dotpos<atpos+2 || dotpos+2>=email.length) { alert("The email (" + email + ") is not a valid e-mail address.

• How to write a virtual conditional breakpoint in java

  - by Phuong Nguyen de ManCity fan

  I'm sorry if the question title may mis-inform you, but I cannot find a proper word to explain that. If you ever working with .NET, you would know that there is Assert class that will automatically wake up and attach debugger if necessary and then have debugger (Visual Studio) pausing at the Assert command, given the Assert command failed. Given I'm running a java program and having debugger connected, then how can I have debugger to break on certain condition without manually setup a break point? I'm expecting something like that: void doSomeThing(String x){ if (x==null) breakDebuggerNow(); }

• mysql C connector unresolved symbols on Win2k8 but not on XP?

  - by jimmy glick

  I have a visual C++ 2008 express project which compiles fine on Windows XP with mysql C connector 6.0.2. When I copy the project over to a Windows Server 2008 x64 machine, it gets a bunch of linker errors like "unresolved external symbol _mysql_server_end@0" "unresolved external symbol _mysql_close@4" "unresolved external _mysql_real_connect@32". Is the mysql C connector 6.0.2 known to not work with Win Server 2008? (Note, the C connector is installed into the same place on both machines, and since I just copied over the project wholesale, it still has the correct libmysql.lib include. The interesting thing is that the errors I get on XP if I remove the libmysql.lib are not the same errors I'm getting on Win2k8, so that's what makes me think it might be an incompatibility...or maybe it's just because win2k8 is x64 and XP is x86?) Thanks

• Regex: Matching against groups in different order without repeating the group

  - by Jimmy

  Let's say I have two strings like this: XABY XBAY A simple regex that matches both would go like this: X(AB|BA)Y However, I have a case where A and B are complicated strings, and I'm looking for a way to avoid having to specify each of them twice (on each side of the |). Is there a way to do this (that presumably is simpler than having to specify them twice)? Thanks

• Ruby open-uri open method loses file extension opening images

  - by Jimmy

  I'm using ruby 1.9.2 along with Rails 3.1.4 and Paperclip 2.4.5. My issue is trying to save a paperclip attachment from a URI loses the file extension and saves the file without one resulting in issues with things like fancybox that require an extension. Some example code: uri = "http://featherfiles.aviary.com/2012-06-13/bbe5f0de1/0c5a672b88ea47ecb4631ac173e27430.png" open(uri) #=> #<File:/var/folders/zc/d69gxhzx10x_bvjrkqgyjgxr0000gn/T/open-uri20120613-27204-i6cldv> Because there is no extension on the temp file paperclip is saving the file without one resulting in issues. Has anyone run into this issue? I've seen multiple answers about using paperclip to store images from a URI but none seem to address the same problem we're running
